Part of: Cohabitation Agreement
A declaration of trust is a signed document that records who owns what share of a property. In England and Wales it sits behind the legal title. So two people can hold a 70/30 split even though HM Land Registry lists them simply as joint owners. Because land is involved, the law requires signed writing to prove the trust (Law of Property Act 1925, s.53(1)(b)). Many couples sign one alongside a cohabitation agreement, although either document can stand alone.
If you put more into a home than the deeds suggest, or a parent helped with the deposit, this guide is for you. It covers England and Wales only, and explains what the document does, what it should cover and how to put one in place. You will also find the tax and marriage points people often miss, and when a court might look behind it.

Key takeaways
- It fixes the shares. The document records each owner’s share of the equity, so the deeds and the money can tell different stories.
- Signed writing is essential. A trust over land must be proved by signed writing (Law of Property Act 1925, s.53(1)(b)).
- The register will not show your split. HM Land Registry keeps trusts off the register, so the title shows who owns the property, not each person’s share (HM Land Registry practice guide 24).
- Courts normally hold you to it. A signed declaration of the shares is treated as conclusive unless a later agreement changes it or a court sets it aside, for example for fraud or mistake (Pankhania v Chandegra [2012] EWCA Civ 1438).
- Marriage changes the picture. On divorce, the court can still divide the home differently (Matrimonial Causes Act 1973, s.24).
- Without one, the court decides. A judge can then declare the extent of each person’s interest (Trusts of Land and Appointment of Trustees Act 1996, s.14).
What is a declaration of trust?
It is a written statement by the legal owners about who really holds the value in a property. In plain terms, the deeds say who can sell, while the trust says who gets the money afterwards. HMRC’s trusts manual describes it in the same way: the legal owner states that they hold the benefit for someone else, without handing over the title (HMRC manual TSEM9520).
Two kinds of ownership sit on top of each other, and the difference matters. Legal title is the name on the register. Beneficial ownership, often called the beneficial interest in property, is the real economic stake: the share of the sale proceeds, and often the share of any rent. A trust splits the two apart. So one person can hold the title while two people share the value.
People also call it a deed of trust, especially when the owners sign it as a deed. “Trust deed” is a looser label that can describe other trust documents too. What matters is whether the document says who owns what, and whether the right people signed it.
What does a declaration of trust cover?
A short document can settle years of argument, because it answers the awkward questions while you still agree on the answers. Most cover the following ground.
- The share each of you owns, either as a percentage or as a fixed sum.
- How the deposit comes back out when you sell, and who it belongs to.
- Who pays the mortgage, the insurance, the ground rent and the repairs.
- What happens to money spent later on an extension or a new kitchen.
- Who can live in the property, and what happens if one of you moves out.
- What happens if one of you wants to sell and the other does not.
- How one of you can buy the other out, and how you value the property.
Parents who help with a deposit often ask for one. Property bought with family money needs a clear record of whether that cash was a gift or a loan. Without that line, a helpful cheque can quietly turn into a family dispute five years later. The same applies to a partner who pays towards a home held in the other’s sole name. A declaration can record their share even though the register never mentions them.
Why doesn’t the Land Registry title show your share?
Co-owners in England and Wales hold a property either as joint tenants or as tenants in common. Joint tenants have equal rights to the whole property, and the survivor takes it automatically. Tenants in common can own different shares, and each of you can leave your share by will (GOV.UK, joint property ownership).
The transfer form you sign on purchase, the TR1, has a trust panel. There, buyers can say they hold as joint tenants, as tenants in common in equal shares, or on other stated trusts. That panel counts as a declaration in its own right. For example, in Pankhania the Court of Appeal held two co-owners to the equal split recorded in their transfer.
However, HM Land Registry keeps the terms of trusts off the register. For tenants in common, it enters a “Form A” restriction instead. That restriction shows there is a trust, but it never records who owns how much. So the entry stays silent on whether yours is half, a third or 70 per cent. For tenants in common, a separate signed declaration is where unequal shares, deposit refunds and buyout rules are set out in full.
This matters most for unmarried couples. The government itself says that couples who live together have limited financial rights if the relationship ends. Our guide to common law marriage in the UK explains what living together does, and does not, give you. In June 2026 the government also consulted on new rights for cohabiting couples. These are proposals, not law, so for now a signed declaration remains the clearest record of your shares.
Which document settles what?
Several documents get mixed up, and people often sign the wrong one. This table orients you before you choose. It is a map of the options rather than advice on which combination fits your circumstances.
| Document | What it settles | When people sign it |
|---|---|---|
| Trust declaration (this guide) | Who owns which share of one property, and how the deposit and equity come back out | On purchase, or when the contributions change |
| Living-together agreement | Wider money between a couple: bills, contents, debts and what happens if you separate | When moving in together |
| Prenuptial agreement | How a couple intend to divide their finances if the marriage ends. Today it is not legally binding on the court | Before a wedding |
| Will | Who inherits your share when you die. It cannot pass on a share held as a joint tenant | Alongside any of the above |
| Land Registry transfer (TR1) | How the title is held and, through its trust panel, sometimes the shares | At the point of purchase |
These overlap, so most couples need two of them rather than one. If you are about to marry, our guide to prenuptial agreements explains how that document works. If you also have children, or a former spouse with a claim, the picture widens again.
How do you make a declaration of trust?
The process is short. Nevertheless, each step exists for a reason, and skipping one is what creates arguments later.
- Agree the numbers first. Write down the deposit, who paid which part of it, and the split you both want. Vague words such as “fair shares” cause the disputes.
- Match how the title is held. If the shares are unequal, the property should be held as tenants in common rather than as joint tenants.
- Put the terms in writing. Set out the shares, the deposit and the buyout rules. The law requires signed writing to prove a trust over land (Law of Property Act 1925, s.53(1)(b)).
- Have every owner sign, ideally as a deed. HMRC notes that the document does not need a witness to the signatures. Even so, signing as a deed, with a witness who also signs, gives clearer evidence of what you both meant (Law of Property (Miscellaneous Provisions) Act 1989, s.1).
- Store it and revisit it. Keep it with the deeds. Update it whenever someone pays off much of the mortgage or funds an extension.
There is no official declaration of trust form. The law asks only for signed writing, and the TR1 trust panel is the nearest thing to a standard format. HMRC’s Form 17 is different: it only changes how married couples and civil partners who live together are taxed on joint property income. A declaration of trust template bought online may suit two buyers splitting everything equally. However, the wording is rarely the problem. The problem is the sums nobody sat down and agreed.
A list cannot weigh a parent’s loan, a home one of you already owned or years of uneven mortgage payments. Those are the calls worth talking through in a free initial consultation before anyone signs.
Does marriage or divorce change it?
Between the two of you, the declaration still counts after a wedding. On divorce, though, the court is not limited to it. It can order one spouse to transfer property to the other (Matrimonial Causes Act 1973, s.24). To decide what is fair, it looks at needs, resources and contributions, and it gives first consideration to the welfare of any child of the family (s.25).
So a declaration signed before the marriage becomes evidence of what you each put in, rather than the final word. Our guide to a financial settlement after divorce explains how the court divides a home when a marriage ends.
Does it affect tax or your mortgage?
Recording shares you already hold is usually simple. Moving value between you is different. Stamp Duty Land Tax can be due when you receive a share and give something of value for it, and taking on part of the mortgage counts as payment (GOV.UK, SDLT on transfers). By contrast, a gift of a share, where you pay nothing and take on none of the mortgage, does not normally trigger it. Transfers between spouses or civil partners under a divorce or dissolution agreement or court order are also exempt.
Income tax follows the shares too. A married couple or civil partners who live together are normally taxed on an even split of income from property they own jointly. To change that, they send HMRC Form 17 with evidence of unequal shares, such as a declaration. Other taxes can depend on the shares as well, so take tax advice before you sign if the home is let or large sums are moving.
Finally, a declaration deals with the shares between the owners. It does not change what either of you owes the lender, so ask your lender whether it needs to know before you sign.
How much does a declaration of trust cost?
Cost tracks complexity, so nobody can quote a single national figure honestly. A short document for two buyers with one deposit sits at the cheap end. Bringing in a parental loan, a share held for a child, or a property one of you already owned pushes the work, and the price, upwards.
Ask for a fixed fee in writing before anyone starts. Then weigh that number against the alternative. A property dispute between unmarried owners runs in the civil courts, where the general rule is that the losing side pays the other side’s costs (Civil Procedure Rules, r.44.2). As a result, a dispute can cost far more than the paperwork that might have prevented it.
Can a declaration of trust be challenged?
Rarely, and that is precisely the point of signing one. The Court of Appeal has confirmed that a signed declaration of the shares is conclusive. The exceptions are a later agreement that changes it, or a promise one of you relied on that overrides it, known as proprietary estoppel (Pankhania v Chandegra). A judge will not revisit the split merely because it now feels unfair to one of you.
Other limits still exist. A court can set the document aside for fraud, undue influence or a genuine mistake about what you were signing. You can also replace it whenever you both agree, by signing a fresh document that says so.
Without one, the argument runs under the Trusts of Land and Appointment of Trustees Act 1996. For a home in joint names, the starting point is equal shares. Whoever wants more must show that you both intended something different. The court judges that from the whole course of dealing between you (Jones v Kernott [2011] UKSC 53). Separately, section 15 lists what the court weighs before ordering a sale, such as why the home was bought. That route is slow and uncertain, as our guide to property claims after separation shows.
Frequently asked questions
What is a declaration of trust document?
It is a signed written record of who holds the beneficial interest in a property, and in what shares. It usually names the owners, states each share, and explains how the deposit and the equity come back out on a sale. Because it deals with land, it must be in writing.
Can I write my own declaration of trust?
Yes. No rule stops you, and a signed homemade document can bind you both. The risk is not the wording but the gaps: an unclear deposit, silence on who pays the mortgage, or no route to a buyout. Those gaps are what later end up in court.
Do I need legal advice to put one in place?
Not as a matter of law. Even so, advice is worth having when the shares are unequal, when a parent contributes, or when one of you already owned the home. Each of you should take advice separately, because your interests differ, and it helps show that each of you understood what you signed.
Can you sign one after buying the property?
Yes. Owners can sign a declaration at any time, although nobody can be made to sign one. If the shares change and one of you takes on more of the mortgage, find out whether Stamp Duty Land Tax applies first.
Is a deed of trust the same thing?
Usually, yes. In property matters, a deed of trust normally means this same declaration, signed as a deed in front of a witness. “Trust deed” is looser and can describe other trust documents. Whatever the label, make sure the document states each owner’s share clearly.
Does it go on the title at HM Land Registry?
No. The document itself stays private, because HM Land Registry keeps trusts off the register. Where you hold the property as tenants in common, a restriction goes on the register instead. However, the register never records the figures, so keep the signed original safe with your deeds.
Buying together, or paying for a home in someone else’s name? Sort the shares before the next payment
Every month that passes adds another payment nobody wrote down, and memories of who paid what fade quickly.

Expert Tip
We are commonly asked whether the shares can wait until after completion. They can, but the conversation gets much harder once the money has moved. On the day of purchase everyone still agrees what the deposit was for. A year later, memories differ and one of you has paid more of the mortgage. So write the split down while the figures are fresh, and revisit it whenever either of you puts in a large sum.
