Declaration of Trust

A Declaration of Trust is a legal document that records how a property is owned between two or more people — who owns what share, on what terms, and what happens to each share in different circumstances. It can be one of the most straightforward documents in estate planning, but also one of the most consequential. Without one, co-ownership arrangements that seem obvious and agreed upon can become genuinely disputed when circumstances change.

What it does

When two or more people own a property together, the Land Registry records their names — but it doesn't automatically record the detail of how ownership is split, or what each person's rights are. A Declaration of Trust fills that gap. It formally records each co-owner's share of the property, how that share was arrived at — whether through equal contributions, unequal deposits, or different mortgage payments — and what should happen to each share on sale, on death, or if the relationship between the owners changes.

It also specifies whether the property is held as joint tenants or tenants in common — a distinction that has significant consequences for what happens on death. Joint tenants own the property equally and indivisibly, and on the death of one owner, the whole property passes automatically to the survivor by right of survivorship, regardless of what either Will says. Tenants in common each own a defined share, which can be unequal, and which passes according to their Will — or the rules of intestacy if there isn't one. A Declaration of Trust is almost always used in the context of tenants in common ownership, because it's here that the detail of each person's share needs to be formally recorded.

When a Declaration of Trust is needed

• Unequal contributions

  • The most common reason for a Declaration of Trust is where co-owners have contributed unequally to a property — a larger deposit from one party, different mortgage contributions, or one person funding a renovation. Without a Declaration of Trust, the law may treat the property as equally owned regardless of what each person actually put in. A Declaration of Trust records the actual position, protects each person's contribution, and ensures that if the property is sold or one person dies, the proceeds are divided in a way that reflects what was genuinely agreed.

• Couples — married and unmarried

  • For married couples, a Declaration of Trust often forms part of a broader estate planning arrangement — severing a joint tenancy and recording the tenants in common position so that each person's share can be directed by their Will. This is the essential first step before putting a Protective Property Trust Will or Flexible Life Interest Trust Will in place. For unmarried couples, the need is often more immediate: without a Declaration of Trust, the legal and beneficial ownership of the property can be genuinely unclear if the relationship ends or one partner dies, regardless of what was intended.

• Parents contributing to a child's property

  • Where a parent contributes to the purchase of a child's home — whether as a deposit, a gifted sum, or an ongoing contribution — a Declaration of Trust can record that contribution formally. This protects the parent's interest in the property if the child's circumstances change — a divorce, for example, where the contribution might otherwise be treated as a gift rather than a share of the property. It also clarifies the position for IHT and estate planning purposes.

• S102B gift planning

  • A Declaration of Trust is an essential document in S102B gift planning arrangements, where a share of the property is gifted to a qualifying occupant. Once the gift has been made, the Declaration of Trust formally records the new ownership structure — who owns what, on what terms — and provides the documentary evidence that the arrangement is a genuine co-ownership rather than a paper exercise. The co-ownership agreement sits alongside it, dealing with the practical day-to-day arrangements between the co-owners.

Something worth understanding

The Land Registry title and the Declaration of Trust are not the same thing

The Land Registry records who the legal owners of a property are. It doesn't record the detail of how ownership is split between them, or the terms on which it's held. A Declaration of Trust operates at the level of beneficial ownership — it records what each person is actually entitled to beneath the legal title. Both documents matter, and they need to be consistent with each other. When a Declaration of Trust is put in place, it should be drafted alongside any necessary changes to the Land Registry title to ensure the two align.

"We see disputes about property ownership far more often than people expect — and almost always, they arise because something that seemed obvious and agreed at the time was never formally recorded. A Declaration of Trust costs very little relative to the clarity and protection it provides."

What it typically covers

• Ownership shares

  • The Declaration of Trust records each co-owner's percentage share of the property — whether equal or unequal — and the basis on which those shares were arrived at. This is the foundation of everything else in the document.

• What happens on sale

  • If the property is sold, the Declaration of Trust sets out how the proceeds will be divided — whether in proportion to the recorded shares, or according to some other agreed arrangement such as the return of a specific sum to one party before the remainder is split.

• What happens on death

  • Each co-owner's share can be directed by their Will, or — if there's no Will — by the rules of intestacy. The Declaration of Trust records that each person's share is theirs to direct, rather than passing automatically to the other co-owner as would happen under joint tenancy.

• What happens if circumstances change

  • A well-drafted Declaration of Trust will include provisions for what happens if the relationship between the co-owners changes — what notice is required to sell, how disagreements are resolved, and whether one person has the right to buy out the other. These provisions matter most in arrangements between people who aren't in a relationship — business partners, parents and children, friends — where the dynamics can shift over time.

Things to consider

• It needs to be kept up to date

  • A Declaration of Trust reflects the position at the time it's drafted. If contributions change — one person pays more of the mortgage over time, or a renovation is funded unequally — the Declaration of Trust should be updated to reflect the new position. An outdated Declaration of Trust can create as much confusion as no Declaration of Trust at all.

• It works alongside a Will, not instead of one

  • A Declaration of Trust records what each person's share is and confirms it can be directed by their Will. It doesn't replace the Will itself. For the Declaration of Trust to achieve its estate planning purpose, each co-owner needs a Will that actually deals with their share — otherwise the share falls into intestacy, and the rules of intestacy decide where it goes rather than the person whose share it was.

• Professional drafting matters

  • A Declaration of Trust is a legal document and needs to be properly drafted to be effective. An informal written agreement between co-owners — however well-intentioned — may not carry the same weight if the arrangement is ever challenged. We work with a qualified Doctor of Law on all property-related documents to ensure they're properly executed and consistent with the Land Registry title.

• Who a Declaration of Trust is relevant for

  • A Declaration of Trust is relevant for anyone who co-owns a property and wants clarity about what each person's share is, how it's protected, and what happens to it in different circumstances. This includes couples — married or unmarried — who want to structure their ownership to align with their estate planning, parents who have contributed to a child's purchase, business partners or friends who own property together, and anyone involved in an S102B gift planning arrangement. It's a relatively simple document that provides a level of clarity and protection that far outweighs its cost.
