Declaration of Trust UK (2026): What It Is, When You Need One, How to Change It and Tax Implications

A declaration of trust (also called a deed of trust or trust deed) is a legal document in which a person declares that they hold property (or an interest in property) on trust for themselves or for another. In the co-ownership context, it records what beneficial share each co-owner holds in the property: (1) THE LEGAL DISTINCTION — LEGAL TITLE vs BENEFICIAL OWNERSHIP: where two people jointly own a property, the Land Registry records the LEGAL TITLE — the names of the registered proprietors. But the legal title does not necessarily reflect who is beneficially entitled to the proceeds on a sale. The beneficial ownership (who gets what from the sale) is a separate question — and without a written declaration, it must be inferred from contributions and intention; (2) WHY A DECLARATION OF TRUST IS NEEDED — THE DEFAULT RULES: without a declaration of trust, the default position depends on how the legal title is held: (a) Joint tenants (most common default on purchase): the parties are presumed to hold the beneficial interest in EQUAL shares. If one person contributed 70% of the purchase price and holds as joint tenant, the default is still 50:50 beneficial split; (b) Tenants in common: the parties are presumed to hold in shares proportionate to their financial contributions — but this is a rebuttable presumption and the position can be disputed; (3) THE WRITING REQUIREMENT — LPA 1925 s.53(1)(b): a declaration of trust concerning land (including a residential property) must be evidenced in WRITING signed by the person declaring the trust. An oral declaration of trust of land cannot be enforced. This formal requirement is essential: without a written declaration, the beneficial shares in a property can only be established by inference from contributions and common intention (see common intention constructive trust); (4) COMMON SCENARIOS WHERE A DECLARATION IS USED: (a) Co-owners holding in unequal shares — one contributed more to the deposit, mortgage or improvements; (b) Parent-assisted purchase — parent contributes a sum for the child's property but does not want to be a legal owner; (c) Nominee arrangements — the legal owner is not the true beneficial owner; (d) Business property — business partners hold premises on trust; (e) Beneficial shares changed — co-owners wish to formalise a change in their respective interests.

A declaration of trust for a co-owned property is a deed that records the beneficial shares and the terms on which they are held: (1) CONTENT OF THE DECLARATION: a typical declaration of trust for co-owned property covers: (a) identification of the property (title number; address); (b) names of the legal owners (registered proprietors); (c) the beneficial shares — e.g. 'Beneficiary A holds 70% and Beneficiary B holds 30%' — expressed as fractions or percentages; (d) what happens to income from the property (rent, if let) — usually in the same proportions as capital; (e) the basis on which either party can require a sale (TOLATA 1996 s.14 application); (f) the arrangements for a forced sale on relationship breakdown — a 'buy-out clause' and valuation mechanism; (g) how contributions are tracked if one party pays more than their share of mortgage or maintenance; (2) EXECUTION — DEED REQUIREMENT: a declaration of trust concerning land must be executed as a deed (signed; witnessed; delivered) under LPA 1925 s.53(1)(b) and the Law of Property (Miscellaneous Provisions) Act 1989 s.1. Each party signs in the presence of an independent witness (not a party to the deed); (3) LAND REGISTRY — FORM JO: once a declaration of trust is in place, the parties should file Land Registry Form JO (application to record a restriction or note on the title). For a property held by tenants in common in unequal shares: (a) the default Form A restriction is placed on the title — this prevents a sole surviving proprietor from selling the property and passing on the equitable interest without a second trustee (ensuring overreaching on a sale); (b) the declaration of trust itself is not filed at the Land Registry (it does not form part of the title register) — it is a private document. But the Form A restriction on the title confirms that there is a trust; (4) COHABITING COUPLES — IMPORTANCE: for unmarried couples buying together, a declaration of trust is essential. Without a written declaration, disputes about the beneficial shares — particularly where one party has contributed significantly more — can only be resolved through expensive litigation about common intention constructive trust (Stack v Dowden [2007]). A declaration of trust removes that uncertainty.

The tax consequences of a declaration of trust depend on whether it reflects an existing position or changes the beneficial ownership: (1) CREATING A DECLARATION OF TRUST ON PURCHASE — SDLT: (a) where a declaration of trust is executed at the time of purchase and simply reflects the actual cash contributions of the parties, there is no SDLT consequence (SDLT is already assessed on the purchase price at the time of purchase); (b) where a party is declared a beneficial owner of a share but does not pay SDLT on that share at the time of purchase, HMRC may require SDLT to be paid on the interest acquired — especially where the trust arrangement means one party is effectively acquiring an interest above their monetary contribution; (c) nominee arrangements: if A buys a property as nominee for B (who provides the purchase price), B is the beneficial owner and SDLT is calculated based on B's purchase price. A is the bare trustee/nominee with no beneficial interest; (2) CHANGING SHARES — SDLT ON CHANGE: if an existing declaration of trust is amended to TRANSFER a share from one beneficial owner to another (e.g. from 50:50 to 70:30), this is a disposal for SDLT purposes. SDLT is payable on the consideration paid (or market value if between connected persons). Where the 'transfer' is a gift between unmarried co-owners (e.g. one transfers their share to the other for no consideration), SDLT is assessed on the market value of the share transferred for connected persons under Finance Act 2003 s.53; (3) CGT ON CHANGE OF SHARES: a change in beneficial ownership — even within a declaration of trust — is a disposal for CGT purposes (TCGA 1992 s.28). If Party A transfers a 20% share of the property to Party B: (a) the transfer is treated as a disposal by A of 20% of the property at market value (even if no money changes hands); (b) A's gain is calculated: market value of 20% at the date of transfer minus A's base cost (20% of original purchase price plus related costs); (c) the gain may attract main residence relief (PPR) if the property is A's main residence; (d) between spouses or civil partners: no gain no loss rule (TCGA 1992 s.58) — transfers between spouses are treated at the same base cost; (4) INCOME TAX ON INCOME FROM JOINTLY HELD PROPERTY — FORM 17 (HMRC HMRC): income from jointly held property is by default split 50:50 for income tax purposes regardless of the actual beneficial shares. To use actual shares, the parties must jointly declare the actual beneficial interests on HMRC Form 17 (Declaration of beneficial interests in joint property and income) — which can only be filed where there is a written declaration of trust already in place.

A nominee arrangement is where the legal title to a property is held in one person's name, but that person is a bare trustee — they have no beneficial interest and hold the property entirely for the benefit of another: (1) HOW A NOMINEE ARRANGEMENT WORKS: (a) Parent (the 'nominee' or bare trustee) takes the legal title at the Land Registry. The property is registered in the parent's name; (b) Child (the beneficial owner) is the true owner — entitled to all of the equity, all of the income from the property, and all proceeds of sale; (c) A declaration of trust is signed by the parent stating: 'I hold the property at [address] on trust for [child's name] absolutely'; (d) The child does not appear on the legal title at all; (2) COMMON USES: (a) parent buys a buy-to-let property for an adult child who cannot get a mortgage (student; poor credit history); (b) parent purchases a property for a child who is under 18 (a minor cannot hold legal title to land under LPA 1925 s.1(6)); (c) protecting beneficial ownership where the registered proprietor is not the economic owner; (3) TAX CONSEQUENCES OF A NOMINEE ARRANGEMENT: (a) SDLT: SDLT is assessed on the beneficial owner (child) — if the child is purchasing a second property, the higher SDLT surcharge (3% additional rate) applies; (b) CGT: any gain on disposal is attributed to the beneficial owner (child) — using the child's own annual exempt amount and CGT rates; (c) Income tax: rental income from the property is attributed to the beneficial owner (child); (d) Stamp duty land tax on bare trust disclosure: HMRC requires the beneficial owner to be disclosed on the SDLT return; (4) MORTGAGE COMPLICATION: lenders typically require the legal owner(s) to be the borrowers. Where there is a nominee arrangement: (a) the nominee/parent is the legal owner and the borrower; (b) the parent is personally liable for the mortgage; (c) if the parent is already using their main residence relief, the property is a second property — higher SDLT rates and no PPR relief on disposal; (5) RISKS: (a) if the nominee/parent dies, the property forms part of their estate for probate (legal title must be transferred). The declaration of trust prevents IHT on the beneficial interest — that belongs to the child. But the parent's estate must apply for probate to transfer the legal title; (b) if the parent becomes bankrupt, a trustee in bankruptcy may seek to override the declaration of trust.

A declaration of trust endures through life events but the parties must actively manage it when circumstances change: (1) ON DEATH OF ONE BENEFICIAL OWNER: (a) if the co-owners hold as BENEFICIAL JOINT TENANTS (not recorded in the declaration of trust as tenants in common): the surviving joint tenant takes the entire beneficial interest by survivorship — the declaration of trust is irrelevant because survivorship operates by operation of law. The declaration cannot override survivorship unless the joint tenancy has been severed; (b) if the co-owners hold as TENANTS IN COMMON in the declaration of trust: the deceased's share passes via their will or intestacy. The declaration of trust records the exact share (e.g. 70%). That 70% share is an asset in the deceased's estate and can be left in the will; (2) INTERACTION WITH A WILL: a will leaving 'all my property' or 'the residue of my estate' automatically includes the deceased's beneficial share under a declaration of trust — even if the will was made before the declaration of trust. Specific bequests should identify the interest clearly; (3) ON RELATIONSHIP BREAKDOWN — UNMARRIED COUPLES: on the breakdown of an unmarried couple's relationship, the declaration of trust is the definitive document establishing the beneficial shares. Without a declaration: the shares are determined by the court based on the common intention constructive trust analysis (Stack v Dowden [2007]; Jones v Kernott [2011]). With a declaration: the court will generally give effect to the written declaration unless it is set aside on grounds of undue influence, fraud, or mistake (Akers v Samba Financial Group [2017]); (4) ON DIVORCE — MATRIMONIAL CAUSES ACT 1973: a declaration of trust does NOT prevent a divorce court redistributing property. The Matrimonial Causes Act 1973 ss.23-24 give the family court wide powers to order property adjustments on divorce — including overriding a declaration of trust between spouses. The family court considers all matrimonial assets regardless of technical legal and beneficial ownership; (5) UPDATING THE DECLARATION: a declaration of trust should be reviewed and updated: (a) when the beneficial shares change (one party pays more of the mortgage; a large renovation; a new capital contribution); (b) on marriage or civil partnership (the MCA 1973 courts can redistribute — an explicit post-nuptial agreement may be preferable); (c) when additional parties acquire a beneficial interest (a third party contributes to the property); (d) when a beneficial joint tenancy is severed.
