Standard Team Agreement
Version 1.0 · In effect from October 20, 2026
https://tillyard.org/policies/team-agreement/v/1.0 · Fingerprint (SHA-256) 9170b4727716c682383c9f2bab7d31409fd718405a2f351ffd60204d5e1fd65b
This is the agreement that the people on a project make with each other. Each person accepts it when they start a project or take a seat at its booth, before the team's first session.
It is the teammates' agreement, so it is written in their voice. In this document we, us and our mean the people on the project, and you means each one of them. The nonprofit that runs Tillyard is called Tillyard here. It supplies this text and keeps a record of who accepted it. It is not a party to the agreement.
In short
- This is an agreement among the people on one project. Tillyard is not part of it and owns nothing we make.
- We own what we make together in one of two ways, chosen on the form when the project opens: we release it under a named open licence (Option A), or we own it equally (Option B).
- Under Option A, once the team makes the work public, anyone may use it on the licence's terms, including for money, and that cannot be undone.
- Under Option B, each owner may show the work and use it for purposes that are not commercial. Any commercial use needs every owner's agreement in writing.
- Each of us is credited honestly for what we did, may show our own part as ours, and may ask not to be named.
- Anyone can leave at any time. What they made stays in the project on the terms we chose, and they keep their credit and their rights in what existed on the day they left.
- Ordinary choices are made by more than half of the team. The lead keeps the booth and is nobody's manager.
- Unfinished work stays within the team until the team makes it public.
- Nobody is paid for this and nobody is working for anybody else. If money, pay or a company comes into it, we stop and write a new agreement away from this site.
- If we disagree, we talk, then put it in writing, then ask a neutral person if we all want one. Nobody gives up the right to go to court.
If this summary and the numbered clauses below ever differ, the clauses govern. They are the agreement.
Before you accept
This section is written by Tillyard to explain the agreement. It is not part of it.
How you accept. The form that opens a project, and the form that offers you a seat, show a short version of this agreement, the version number of this full text with a link to it, and a box to tick, which starts empty. The tick is your acceptance of the full text of this document, in the version the form names, with the ownership option the project was opened with. Open the full text and read it before you tick: the five lines are a summary, and it is the numbered clauses that you are agreeing to. Tillyard records the version and the date against your seat, and you can see both in your account.
What the form shows. The short version on the form is these five lines. The screen reads:
- What we make here belongs to us, the people recorded on this project. Tillyard owns none of it and may show only what we put on our project page, until we take it down.
- We own it as chosen above.
- If someone leaves, what they made stays in the project on those terms, and they may still show their own part as theirs.
- Nobody sells the project or uses it in a business unless everyone recorded on it agrees in writing.
- Nobody is paid for this and nobody is working for anybody else. If that changes we stop and write a new agreement off this site.
Those five lines are a summary. Where they and the numbered clauses differ, the numbered clauses govern.
The two options, side by side. The table states what each option does. It does not say which to choose; that is for your team.
| What to compare | Option A: an open licence | Option B: equal co-ownership |
|---|---|---|
| Who holds the rights | Each person keeps the rights in what they made, and licenses it | The owners hold the whole of it together, in equal shares |
| Who may use the work | Once it is public, anyone, on the licence's terms | The owners. Nobody else without every owner's agreement |
| Use for money | Allowed to anyone by the licence, with no duty to share | Only with every owner's agreement in writing |
| Can it be undone | No. A released open licence is permanent | The owners can change the arrangement if every one of them agrees |
When this agreement is not enough. It was written for student projects. It was not written for running a business, employing anyone, taking investment, or handling an invention that matters. If your project is heading that way, clause 11 tells you to stop and make your own agreement, and you should get advice from someone qualified.
What Tillyard does not do. Tillyard does not advise on this agreement, recommend one option over the other, interpret it, or enforce it. Reading it carefully is up to you. If it does not fit your team, you can make your own written agreement as well, or instead.
The agreement
1. Who agrees, and when it starts
1.1 This agreement is between the people who take a seat on the project named on the form where each of us accepted it (the project). Together we are the team.
1.2 Each of us accepts this agreement by ticking the box on the form that opens the project or offers us a seat. That tick is our signature. We each accept the same text, with the same ownership option.
1.3 The agreement starts when the second person takes a seat. Each person who takes a seat later joins it with everyone already bound by it, and nobody needs to accept again when that happens.
1.4 Each of us confirms that we are 18 or over, that we are free to make this agreement, and that no promise we have made to anyone else, such as a term in a contract with an employer or a rule that comes with a scholarship or a grant, stops us keeping it.
1.5 A person who was invited and has not taken a seat is not part of this agreement.
2. Words we use
Where this agreement uses a word that Tillyard's documents define, such as member, project, booth, seat, lead or counted session, it has the meaning given in Definitions and the Projects and Collaboration Terms. The words below are added for this agreement.
- Project work is everything any of us makes for the project while holding a seat, in any form: writing, code, designs, data we gather, models, recordings, the write-up and the like. It does not include earlier work or outside material.
- A contribution is the part of the project work that one person made.
- Earlier work is anything one of us made before joining the project, or makes outside it, even if we bring it in.
- Outside material is anything made by someone who is not on the team, such as a code library, a dataset, a typeface, a photograph or a passage of text.
- A seat, the lead, a counted session and the booth mean what they mean on Tillyard's pages for projects.
- Commercial use means selling the project work or a licence to it; using it in a business, or to earn money or anything else of value, including through advertising, subscriptions, sponsorship or paid services; or using it to raise investment. Showing the project or our own part in a portfolio, on a résumé, in an application, in an interview or in a talk is not commercial use.
- In writing means in a message that can be kept and that shows who sent it: a message in the booth's thread, an email, or a signed document. Where this agreement asks for several people's agreement in writing, each of them sends their own message. Saying it aloud is not enough.
- Made public means put somewhere that people outside the team can reach it, by a decision of the team under clause 8.
3. What each of us brings
Each of us promises the others that:
3.1 It is ours to bring. What we contribute is our own work, or something we have the right to bring into the project on the terms of this agreement.
3.2 Nobody else has a claim we have not mentioned. We have checked, and nothing we contribute belongs to, or is restricted by, a college, an instructor, a lab, a research sponsor, an employer or a client. The answer the project gave to "Whose it is" is true for our own contribution. If that stops being true, we tell the team straight away.
3.3 We say what we borrowed. We tell the team about any outside material we bring in and the licence it comes under. We bring in only material whose licence fits the ownership option we chose, and we keep the notices and credits its licence asks for.
3.4 We say what a machine made. We tell the team which parts of our contribution were made with an AI tool and which tool, and we follow that tool's terms. We understand that material generated wholly by a tool may not be protected by copyright, which can affect both options.
3.5 No secrets and no private details. We do not bring in information we hold in confidence for someone else, or private information about people who have not agreed.
3.6 We put it right. If something we brought in turns out not to have been ours to bring, we tell the team as soon as we know and help take it out or replace it.
4. Who owns what we make
4.1 It is ours. The project work belongs to the people who made it, in the way this agreement sets out. Tillyard owns none of it and has no share in it. Each of us has separately given Tillyard permission to store and show the text we type into its pages. That permission is set by Tillyard's own terms, and this agreement adds nothing to it.
4.2 One of two options applies. We own the project work as chosen on the form that opened the project: under Option A (clause 5) or under Option B (clause 6). Only the chosen option applies, and the other clause is of no effect for this project.
4.3 Earlier work. Earlier work stays the property of the person who made it. If you bring earlier work into the project, you give the team permission to keep it in the project work and to use it, as part of the project work, in every way the chosen option allows the project work to be used. Under Option A that means it goes out under the open licence with everything else. If you do not want that, do not bring it in. You stay free to use your earlier work anywhere else.
4.4 Outside material. Outside material stays the property of whoever owns it and is used only as its licence allows.
4.5 Ideas. This agreement covers the things we make. It gives none of us ownership of an idea, a method or a fact. Clause 10 says what we keep within the team.
4.6 The project's name. The project's name belongs to the team. Nobody registers it, takes a web address or an account in it for their own use, or uses it for a business or another project, unless everyone who holds a seat, and under Option B every owner, agrees in writing.
4.7 Inventions. If we think we have made something that could be patented, we talk before anyone makes it public, because publishing can end the chance to patent it. Patent law, not this agreement, decides who counts as an inventor. Nobody files an application alone, and we get advice before anybody files.
4.8 Things held for the team. A shared account, repository, folder or web address that one of us opens for the project is held for the team, and clause 9.5 applies to it.
5. Option A: we release it under an open licence
This clause applies only if the project was opened with an open licence.
5.1 The licence. The chosen licence is the one named on the form that opened the project and shown on the project's pages. The form offers these:
| Licence | In a sentence | Written for |
|---|---|---|
| MIT License | Anyone may use, change and share the work for any purpose if they keep the copyright and licence notice | Software |
| Apache License, Version 2.0 | As MIT, with an express patent licence from each contributor and a duty to state changes | Software |
| Creative Commons Attribution 4.0 International (CC BY 4.0) | Anyone may use, change and share the work for any purpose if they give credit | Writing, images, data and other material that is not software |
| Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) | As CC BY, and anything built on the work must be shared under the same or a compatible licence | The same |
| CC0 1.0 Universal | The makers give up their rights as far as the law allows, so that anyone may use the work for anything with no conditions | Data and material meant for the widest reuse |
The licence's own published text is its terms. The table is a guide and does not change them.
5.2 What each of us does. Each of us applies the chosen licence to our own contribution, and to our share of anything two or more of us made together. Under every licence in the table except CC0 that means we each keep the copyright in what we made and give a licence. Under CC0 it means we each give up our rights in it as far as the law allows. The licence runs:
- to every other person on the team, from the moment the contribution is made; and
- to everyone else, from the moment the project work is first made public.
5.3 Before it is made public. Until the team makes the project work public, it is unfinished work under clause 10, and nobody outside the team has a licence to it. The team decides when to make it public under clause 8.3. A contribution that has been taken out of the project work before then is not released.
5.4 Once it is public, it stays public. An open licence cannot be taken back from people who already have the work. Leaving the team, a change of mind, the end of the project or the end of this agreement does not undo it. We each accept that before we contribute.
5.5 Notices and names. We put the notice the chosen licence calls for with the project work wherever we publish it, in a form such as "Copyright [year] the contributors to [project name]", with the name of the licence. Each of us chooses whether our own name is listed.
5.6 Anyone may use it, and that includes us. Every licence in the table lets anyone use the released work for money, on the licence's terms, without asking and without sharing what they earn. Each of us may do the same. If that is not what we want, we should have chosen Option B. These things still need the agreement in writing of everyone who holds a seat and everyone whose contribution is in the work:
- any commercial use of the project work before it has been made public;
- giving anyone rights that go beyond the chosen licence, such as an exclusive licence or a licence without the licence's conditions;
- using the project's name in a business, or telling anyone that you act for the team or the project.
5.7 Our own contributions. Because each of us keeps the rights in our own contribution, each of us may also use it, and license it to others, in any other way we like. That does not take away the licence already given under 5.2.
5.8 Changing the licence. The licence on work that is already public cannot be withdrawn. Releasing later versions under a different licence needs the agreement in writing of every person whose contribution is in them, including people who have left.
5.9 Projects with more than one kind of work. The chosen licence covers all of the project work. If the project has both software and other material, the team may agree in writing to apply one of the software licences in the table to the software and one of the Creative Commons licences to the rest. If we do, we say so in the write-up and beside the work, because the project's pages at Tillyard show only the licence chosen on the form.
5.10 Patents. The licences in the table deal with patents differently, and some do not license them at all. If a patent could matter, clause 4.7 applies before anything is made public.
6. Option B: we own it equally
This clause applies only if the project was opened with "We own it equally".
6.1 Who the owners are. A person becomes an owner when they have sat two counted sessions on the project. That is the same line the booth draws for a say in the credit at the end. If the booth cannot count sessions for a reason outside the team's control, the people who hold a seat may agree in writing, all of them, that a person has become an owner. Once a person is an owner they stay one, whether or not they stay on the team, unless they give up their share under clause 9.7.
6.2 Equal shares. The owners own the project work together, in equal undivided shares, however much or little each of them did. To make that so, each of us, on becoming an owner, transfers the rights in our contribution to all the owners together, and does the same with each later piece as we make it. This is a transfer of ownership, and the tick by which we accepted this agreement is our signature to it. When another person becomes an owner, the shares become equal again among all the owners.
6.3 What a share covers. An owner's share covers the project work as it stands on the day they leave the team, including what was made before they joined. It does not cover what the others make after they have gone. Because later work is built on earlier work, clause 6.5 still applies to the whole.
6.4 What each owner may do alone. Without asking anyone, each owner may:
- show and describe the project and their own part anywhere, such as a portfolio, a résumé, an application, an interview or a talk;
- keep a copy of the project work;
- use the project work for study, teaching, research and any other purpose that is not commercial use;
- build on the project work for a purpose that is not commercial use. What they add is theirs. What they built on stays ours;
- reuse a part that they alone made in other work of their own, for any purpose, so long as none of anyone else's contribution comes with it and they do not use the project's name;
- ask a website to take down a copy of the project work that was posted without permission, telling the other owners when they do.
Each of these is subject to clause 7 on credit and clause 10 on unfinished work.
6.5 What needs every owner. Each of these needs the agreement in writing of every owner:
- any commercial use of the project work or of a substantial part of it;
- giving anyone outside the owners permission to use the project work, including releasing it under an open licence, other than showing it as 6.4 allows;
- selling, transferring or pledging the project work, or an owner's share, to anyone, including another owner;
- registering a copyright, a trademark, a patent or a web address for the project in the names of fewer than all the owners;
- starting or settling a legal claim about the project work in the name of the team.
An owner may say no for any reason, and may make a yes depend on conditions, such as how money is shared. Silence is not agreement, except as clause 6.7 provides.
6.6 Money. When the owners agree to a commercial use, they agree in writing at the same time how the money from it is shared and which costs come out first. If they agree a use and say nothing about money, what is left after the costs they agreed is shared equally among the owners. No owner owes the others any money for a use that 6.4 allows.
6.7 An owner who cannot be reached. If the other owners ask an owner in writing to agree to a commercial use, at every address they have for that owner, and ask again at least 30 days later, and 60 days pass from the first request with no answer, the other owners may go ahead with that use, on these conditions:
- the use gives nobody an exclusive right and transfers no ownership;
- they keep a record of the money that comes in and set aside that owner's equal share, and pay it over with an account when asked;
- once that owner answers, any new use needs their agreement like anyone else's. A use already begun under this clause may continue.
6.8 A person who is not yet an owner. What a person makes for the project before they become an owner stays theirs. They give the owners permission, free of charge and without an end date, to keep it in the project work and to show, copy and use the project work with it in, for any purpose that is not commercial use. A commercial use needs that person's agreement in writing as well, unless their contribution is taken out first. If they later become an owner, clause 6.2 applies to what they made before as well as after.
6.9 If a share passes to someone else by law. If an owner's share passes to another person by operation of law, that person takes it subject to this agreement.
6.10 Changing to an open licence. The owners may later release the project work under an open licence if every owner, and every person whose contribution is in it under 6.8, agrees in writing. Clause 5 then applies from the date they agree, and the release cannot be undone.
7. Credit
7.1 Honest credit. Each of us is credited for what we did, no more and no less. When the booth asks "Who did what", each of us claims only the parts we did, ticks for teammates the parts we know they did, and answers alone. Nobody presses anybody about their answers, and nobody trades them.
7.2 Credit goes with the work. Wherever any of us shows the project, we name the people who worked on it and their parts, unless a person has asked not to be named. Under Option A the chosen licence's own rule on credit applies as well.
7.3 Being named, or not. Each of us may ask not to be named in connection with the project. The others then leave that person's name out of anything new, and take it out of places the team controls within a reasonable time.
7.4 Our own part. Each of us, including a person who has left, may show our own part as ours and describe the project truthfully. Nobody claims a teammate's part, and nobody describes the project as theirs alone.
7.5 Credit is not ownership. Whether a person is credited, and for what, does not change who owns the project work. What Tillyard's pages show about credit is decided under Tillyard's own rules. If we disagree about a credit line there, we use Tillyard's tool for questioning a part. Whatever Tillyard displays does not decide what we owe each other under this agreement.
7.6 People who helped from outside. A person who is not on the team is not part of this agreement. We use their work only if they have given us the right to, and we thank them by name only if they agree.
8. How we decide things
8.1 A team of equals. Each person who holds a seat has one voice. The lead keeps the booth: invitations, the card and the seats. The lead has no larger say than anyone else, sets nobody's hours and gives nobody tasks.
8.2 Day to day. The people doing a piece of work decide how to do it, in the open, at the table or in the thread. If anyone on the team objects, more than half of the people who hold a seat decide.
8.3 More than half of the team. These need the agreement of more than half of the people who hold a seat:
- changing the project's aim;
- offering a seat to a new person. The lead tells the team before offering one;
- making the project work public for the first time;
- entering the project for a prize or a competition;
- releasing a person's seat for a reason other than their own request or their having gone quiet (clause 9.3);
- agreeing that the project is finished, or closing it.
8.4 Everyone. These need the agreement in writing of every person this agreement names for them: the matters in clause 5.6 or clause 6.5; using the project's name under clause 4.6; and changing this agreement under clause 14. Whether the project has a public page at Tillyard is decided by each recorded person's own switch, under Tillyard's rules.
8.5 How we count. A decision under 8.3 is made in the thread, so that there is a record. A person who has been asked in the thread and has not answered within seven days is left out of the count. A person who has not answered is never counted as agreeing to anything in 8.4.
8.6 A tie. If the team is evenly split, the thing is not done.
8.7 Nobody speaks for the others. None of us signs anything, makes a promise, spends money or takes on a debt in the name of the team or of another teammate, unless every person who would be bound has agreed in writing.
9. If someone leaves, is released or goes quiet
9.1 Leaving is free. Any of us may leave at any time and need give no reason. A person who leaves tells the team in the thread if they can.
9.2 What stays. What a person made stays in the project on the terms of the option we chose. Under Option A, the licence they gave continues. Under Option B, an owner who leaves is still an owner, with the share described in clause 6.3 and every right in clause 6, and a person who was not yet an owner leaves behind the permission in clause 6.8. The team may go on building. A person who leaves has no right to have their contribution taken out, though the team may agree to take it out.
9.3 Releasing a seat. The lead releases a person's seat only:
- at that person's request;
- when the person has gone quiet (clause 9.4); or
- when more than half of the other people who hold a seat agree, after the person has been told the reason in the thread and has had seven days to answer.
A person whose seat is released keeps everything a person who leaves keeps.
9.4 Going quiet. A person has gone quiet if, for 30 days, they have not come to a session, written in the ledger or the thread, or answered a question put to them by name in the thread, and they then do not answer a message in the thread asking whether they are still in within 14 days. The team may then treat them as having left. They can be invited back.
9.5 Handing things back. No later than 14 days after leaving, a person hands over to the team whatever they hold for the project that the team needs in order to carry on, such as control of a shared account, repository or web address. They do not delete project work or lock the team out. The team decides what access the person keeps. The person may keep their own copy of the project work as it stood, for the uses this agreement allows them, and stays bound by clause 10.
9.6 Credit after leaving. Leaving does not change what a person did. Clause 7 applies to them as before, and the booth's own rules say whether they are asked at the end.
9.7 Giving up a share. Under Option B an owner may give up their share to the other owners by saying so in writing to all of them. They are owed nothing for it unless that was agreed. They keep their rights under clause 7 and their right to reuse a part they alone made under clause 6.4.
9.8 The last person. If only one person is left on the team, they may carry on. They remain bound to everyone else for what was made before.
10. Unfinished work stays within the team
10.1 What this covers. Project work that has not been made public; what teammates say in the thread or at the table about the project's plans; and anything a teammate brings to the team and says is private.
10.2 The promise. None of us shows, sends or describes these things to anyone outside the team in a way that gives them away, or uses them for another project or a business, unless more than half of the people who hold a seat agree. Any of us may show unfinished work in confidence to a teacher, a mentor or an adviser to get feedback, unless the team has decided otherwise, and we tell that person that it is unfinished and private.
10.3 What it does not cover.
- our own part, shown without giving away anyone else's unfinished work;
- anything that is already public through no fault of ours;
- anything we knew before, or worked out for ourselves without using the team's material;
- anything we are required by law to disclose;
- anything we tell Tillyard, a college or the authorities in order to report a problem, and anything we tell a lawyer in order to get advice.
10.4 How long. The promise lasts until the thing is made public, or for two years after the project closes, whichever comes first. It continues for a person who leaves.
10.5 Not a bar on other work. Each of us is free to work on similar things, alone or with other people, at any time, using our own skills and what we know in general. The promise is about the team's unpublished material, and nothing more.
10.6 The booth is not a vault. Tillyard can read text typed into its pages in the cases its own notices describe, and has promised us no confidentiality. We do not put anything in the booth that must stay secret.
11. Nobody is paid, and nobody works for anybody else
11.1 No pay. Nobody is paid for working on the project, and nobody has been promised pay, a share to be worked out later, or any other reward for it.
11.2 Nobody works for anybody. None of us is another's employee, contractor, agent, intern or trainee, and none of us is Tillyard's. Nobody sets anyone's hours or directs anyone's work.
11.3 Not a business. The project is not a business, and we do not intend to form a partnership or a company by working on it. We understand that the law can treat people who carry on a business together for profit as partners whatever they intend, and that partners can be responsible for each other's business debts. That is one reason for 11.6.
11.4 Costs. Each of us pays our own costs. A cost is shared only if the people sharing it agreed to in writing beforehand, and then equally among them. Nobody has to spend money to keep their seat.
11.5 Prizes and money we did not plan for. If the project is given a prize or any other money or thing of value, it is shared equally among the people who held a seat when it was entered or given, and under Option B among the owners, unless everyone entitled to a share agreed otherwise in writing first.
11.6 If any of that changes, we stop. Before anyone is paid for work on the project, before the project sells anything or takes money from anyone, before a company is formed for it, and before anyone talks to an investor about it, we stop and write a new agreement, away from Tillyard, that every one of us signs. We get advice from someone qualified. Until the new agreement is signed, this one goes on governing what we have already made.
11.7 Venture ideas. If the project is a venture idea, each of us joined as a co-owner of the idea, with a say in where it goes, and not to carry out tasks for someone else's business. This agreement gives nobody shares in any company. If a company exists or is formed, a stake in it needs its own signed document.
11.8 If a part is ever paid. If Tillyard's pages come to allow a paid part and one of us is to be paid for one, clause 11.6 applies first. The pay is a separate arrangement between the person paying and the person paid, and it changes nothing about who owns the project work unless everyone agrees in writing.
12. If we disagree
12.1 Talk first. We raise a disagreement with the people it affects, at the table or in the thread.
12.2 Then write it down. If talking does not settle it, any of us may post a short note in the thread saying what the disagreement is and what they propose. Everyone it affects answers in writing no later than 14 days afterwards.
12.3 Then a neutral person, if we all want one. If it is still not settled, we may ask one person we all accept, who is not on the team and has no stake in the outcome, to hear each side and suggest an answer. The suggestion binds nobody unless everyone affected accepts it in writing. Many colleges offer students a mediation or ombuds service.
12.4 Meanwhile. While a disagreement is open, nobody makes it worse. Nobody deletes project work, locks others out of what the team shares, makes unfinished work public, or starts a commercial use.
12.5 Credit on Tillyard's pages. A disagreement about a credit line shown by Tillyard goes through Tillyard's own tool. Tillyard decides only what its pages show.
12.6 Reporting conduct. Reporting a person's conduct to Tillyard, to a college or to the authorities is always allowed. It is never a breach of this agreement, and nobody is treated worse within the team for doing it in good faith.
12.7 Courts. Nothing in this clause takes away anyone's right to go to court, and nothing in this agreement requires arbitration. This agreement does not choose a state's law or a particular court. The ordinary rules decide both.
12.8 Tillyard is not our referee. Tillyard does not interpret this agreement, decide who is right under it, or enforce it.
13. Tillyard is not part of this agreement
13.1 Tillyard supplies this text and keeps a record of who accepted which version and when. It is not a party to this agreement. It owes none of us anything under it, and it has not checked that it suits our project.
13.2 Tillyard owns none of the project work and has no share in any money the project earns.
13.3 What each of us owes Tillyard, and what it may do with the text we type into its pages, is set by its own terms. This agreement does not change them. Between us, this agreement governs. If the two seem to disagree about what Tillyard may do or show, Tillyard's terms govern that point.
13.4 Nobody outside the team has rights under this agreement. Under Option A, people outside the team get their rights from the chosen licence itself.
14. Changing or ending this agreement
14.1 Changes. This agreement can be changed only in writing, by every person who holds a seat together with every other person whose rights the change would affect, such as an owner who has left or a person whose contribution is still in the work.
14.2 What Tillyard's pages show. The booth keeps showing the option the project was opened with. If we change it, we say so in the write-up.
14.3 How long it lasts. This agreement has no end date. Clauses 4 to 7, 9, 10 for the time it states, 11.5, 12 and 13 go on applying to a person after they leave and to all of us after the project closes.
14.4 New standard texts. If Tillyard publishes a new version of its standard agreement, that does not change ours.
14.5 Replacing it. A later agreement that every one of us signs may replace this one, in whole or in part.
15. General points
15.1 The whole agreement. This document, with the option chosen on the form, is the whole of what we have agreed about the project. It replaces anything we said or wrote to each other about these things before, and nothing said aloud changes it.
15.2 If part of it fails. If a court finds that part of this agreement cannot be enforced, that part is read as narrowly as it needs to be, and the rest stands.
15.3 Signing. Each of us signs by ticking the box. Each tick is a separate signature to the same agreement, and a record of it is as good as the original.
15.4 Letting something go. If one of us does not insist on a right once, that does not give the right up for the future.
15.5 The law's limits. Nothing in this agreement takes away a right that the law does not allow a person to sign away.
15.6 No passing it on. None of us may hand our place in this agreement to someone else.
15.7 Summaries and headings. The headings, the section "In short", the section "Before you accept" and the five lines on the form are there to help. Where they differ from the numbered clauses, the numbered clauses govern.
15.8 No advice from Tillyard. Tillyard did not advise any of us on this agreement, did not recommend one ownership option over the other, and none of us relied on it for legal advice. Each of us had the chance to read the full text and to take our own advice before accepting.
