A deed of trust in the UK — also called a declaration of trust — is a legally binding document that records who is beneficially entitled to what share of a property’s value, even when those shares don’t match the names on the title. It’s the tool that protects unequal deposit contributions, hidden financial stakes, and money put in by people who aren’t on the deeds at all. Without one, everyone named on the title is presumed to own an equal share, whatever they actually paid.
Why the Document Exists: Legal vs Beneficial Ownership
Every property in England and Wales carries two layers of ownership. Legal ownership is the name or names registered at HM Land Registry: the people who can sign contracts and deal with the property.1GOV.UK. Trusts, Settlements and Estates Manual – TSEM9916 Beneficial ownership is about money — who is entitled to the equity and sale proceeds. There is no cap on the number of beneficial owners, and their shares don’t have to be equal.
A deed of trust bridges these two layers. It says, in effect, that the names on the title hold the property on trust for a specified group of people in specified shares. That’s the whole function of the document.
Joint Tenants or Tenants in Common
Before a deed of trust becomes relevant, co-owners have to pick how they hold the property, because the choice changes what happens to a share on death.
Joint tenants each have an equal right to the whole property. If one owner dies, the survivor automatically inherits the deceased’s interest through the right of survivorship, regardless of what any will says. This is the default for many married and cohabiting couples.2GOV.UK. Tax on Property, Money and Shares You Inherit – Joint Property, Shares and Bank Accounts
Tenants in common each own a distinct share, which can be split 50/50, 70/30, 90/10, or any other ratio. When one owner dies, their share doesn’t pass automatically to the co-owner. It goes to whoever they named in their will, or under the intestacy rules if there is no will.2GOV.UK. Tax on Property, Money and Shares You Inherit – Joint Property, Shares and Bank Accounts
A deed of trust almost always sits alongside a tenancy in common. Recording unequal shares is the whole point, and that contradicts the equal-interest structure of a joint tenancy.
When You Actually Need One
The most common trigger is unmarried couples buying together with different deposit contributions. Marriage and civil partnership carry statutory protections on separation. Unmarried partners don’t get those, and a deed of trust fills the gap by recording what each person put in and what they can take out.
Parents who help fund a child’s purchase are another frequent case. Without formal documentation, that contribution can disappear into the property’s equity with no legal claim attached. A deed of trust can record the parents’ beneficial interest even though their names never go on the title.
Friends buying together, business partners, investors pooling resources, and anyone using an inheritance they want ring-fenced from a shared property all sit in the same category. The common thread: whenever money in doesn’t match names on the title, this is the document that protects the mismatch.
What the Deed Sets Out
A well-drafted deed of trust typically covers:
- Beneficial shares — the exact percentage or fixed sum each person is entitled to from the equity. Some deeds use percentages; others allocate fixed amounts first (to reflect deposits) and split the remainder by a different ratio.
- Deposit and purchase contributions, including any family gifts or loans.
- Mortgage payments — who pays, and whether paying a larger share increases that person’s beneficial interest over time.
- Running costs: bills, maintenance, insurance.
- Sale triggers — when the property can be sold, and what happens if one owner wants to sell and another doesn’t.
- Buyout provisions, including whether a professional valuation is required.
- Dispute resolution, sometimes with mediation or arbitration clauses to avoid court.
How to Create One Properly
A deed of trust is private but not informal. To be valid as a deed under the Law of Property (Miscellaneous Provisions) Act 1989, the document must make clear on its face that it’s intended as a deed, and each signatory must sign in the presence of a witness who then signs to confirm they saw it.3Legislation.gov.uk. Law of Property (Miscellaneous Provisions) Act 1989 – Section 1
Get a property solicitor to draft it. Templates exist online, but the consequences of a bad draft are severe enough that professional drafting earns its cost. Solicitor fees for a straightforward deed typically range from a few hundred pounds to over £1,000, depending on complexity. Two or three quotes is sensible.
The Form A Restriction
The deed itself isn’t filed at the Land Registry. But when property is held as tenants in common, a Form A restriction should be entered on the title. It prevents a sole surviving legal owner from selling the property or otherwise generating capital money from it without a court order.4Legislation.gov.uk. The Land Registration Rules 2003 – Schedule 4 Standard Forms of Restriction In practice, any buyer’s solicitor sees the restriction, realises there are beneficial interests behind the title, and insists on a second trustee being appointed before completion. Without that safeguard, a sole surviving owner could sell and keep the entire proceeds.5Legislation.gov.uk. The Land Registration Rules 2003 – Rule 94
Mortgage Lender Consent
Check whether your lender needs to consent before the deed is finalised. In most cases the deed simply records the equity split between co-owners and doesn’t affect the lender’s security, so formal consent isn’t needed. If the deed gives a beneficial interest to someone not named on the loan, or otherwise touches the mortgage, the lender may want to review it. Your solicitor should advise on whether notification is necessary.
Tax Consequences
A deed of trust can shift your tax position in three main ways.
Capital Gains Tax
When the property is sold, each beneficial owner is liable for CGT on the gain attributable to their share (assuming the property isn’t their main residence, which qualifies for Private Residence Relief). For the 2026/27 tax year, residential property gains are taxed at 18% for basic-rate taxpayers and 24% for higher-rate taxpayers, with an annual exempt amount of £3,000 per person.1GOV.UK. Trusts, Settlements and Estates Manual – TSEM9916 Transfers between spouses and civil partners are treated as no gain, no loss, so no CGT arises at the point of transfer between them.
The deed matters here because HMRC attributes the gain by the beneficial shares. If you own 30% of the equity, you’re taxed on 30% of the profit — not an equal split with your co-owners.
Stamp Duty on the Deed Itself
A declaration of trust executed on or after 13 March 2008 is generally not chargeable with stamp duty unless its true effect is a transfer on sale.6GOV.UK. HMRC Stamp Taxes Shares Manual – STSM081070 Simply recording the shares agreed at purchase triggers nothing. But creating a deed after purchase that changes beneficial ownership, with money changing hands for the interest transferred, can trigger Stamp Duty Land Tax on the consideration.
Inheritance Tax
The IHT nil-rate band remains £325,000 for the 2026/27 tax year, with qualifying estates able to pass on up to £500,000 (or £1 million for a surviving spouse or civil partner) before IHT applies.7GOV.UK. Inheritance Tax Nil-Rate Band and Residence Nil-Rate Band Thresholds From 6 April 2026 The deed sets the value of each owner’s share for IHT. Because tenants in common can leave their share by will, that share forms part of the taxable estate on death. Under a joint tenancy, survivorship applies and the deceased’s share passes outside the will entirely.
One trap to note: where a parent transfers a beneficial interest into a trust but keeps benefiting from the property (for example, living there rent-free), HMRC may treat it as a gift with reservation of benefit, and the value still counts as part of the estate for IHT.8GOV.UK. Trusts and Inheritance Tax
How the Deed Interacts With Your Will
If you hold as tenants in common and die, your share passes under your will or, without one, under the intestacy rules — which may direct it to a relative you wouldn’t have chosen.2GOV.UK. Tax on Property, Money and Shares You Inherit – Joint Property, Shares and Bank Accounts The surviving co-owner doesn’t inherit it automatically.
The deed of trust quantifies what that share was actually worth. Without one, executors and surviving co-owners can end up arguing about contributions with limited evidence to settle it. With one, the beneficiary named in the will can enforce a specific percentage rather than negotiating from scratch.
Anyone drafting a deed of trust should have an up-to-date will alongside it. The two documents work together: the deed records the share; the will directs where that share goes.
Changing or Cancelling a Deed of Trust
A deed of trust is not permanent, but you can’t alter or cancel it unilaterally. Every party named in the deed has to consent.
Two routes exist. A deed of variation amends specific terms while keeping the rest of the document intact. A deed of surrender cancels the existing deed entirely, leaving the parties free to draft a new one. Many solicitors recommend surrender-and-replace for anything beyond a minor tweak, because it avoids confusion about which terms have been overridden.
Once the replacement is drafted, signed, witnessed, and dated, it becomes the operative document. If a Form A restriction is on the title and the changes affect the ownership structure (removing a beneficial owner, for instance), the Land Registry entry needs updating accordingly. As with the original, professional drafting is worth it — a badly drawn variation can create more problems than it solves.
