The Deed of Trust, explained line by line

A Declaration of Trust is a legal document that sits behind the Land Registry title and records the beneficial ownership of a property: who really owns what, in what proportions, and on what terms. The title register shows the legal owners; the trust deed shows the money.

It is not a mortgage agreement and it does not bind your lender. If one owner stops paying, the lender can still pursue every borrower for the full debt. The deed governs how owners settle up between themselves.

Ownership shares: the headline percentages, plus the deposit figures they were derived from. Ambiguity here is the number one source of later disputes.

Contributions: who pays the mortgage, insurance, service charge and maintenance, in what proportion, and what happens if someone falls behind. Good deeds include a grace period and a mechanism for the paying owner to recover arrears from the defaulter's share on sale.

Occupancy: who may live there, whether a room can be sublet, and whether a partner can move in. Say it now, calmly, rather than in year three.

Sale and exit: notice periods, how the property is valued, the right of remaining owners to buy out the leaver, and a longstop that allows a sale if no agreement is reached.

Death and incapacity: what happens to a share, and whether the survivors get first refusal to buy it from the estate.

The most common failure point is a vague phrase like 'at market value'. Define the mechanism: each side appoints a RICS surveyor, the figure is the average of the two, and if they differ by more than 5% a third independent surveyor is appointed and their figure binds.

Also state who pays for the valuation and how long the buying owner has to complete, usually 60 to 90 days from the valuation date.

Ideally each co-buyer takes their own legal advice on the deed, or at least signs a waiver confirming they were told they could. It costs a little more and makes the document far harder to challenge later.

Review the deed whenever circumstances change materially: a new partner moving in, a remortgage, a significant capital improvement, or a change in who pays what.
