What a declaration of trust solicitor actually costs, and what the fee buys

This page covers what the document is, why unmarried and unequal co-owners need one most, what actually drives the fee, what has to be in it, how it reaches HM Land Registry, and the tax trap most often missed before you sign. It is about property co-ownership declarations of trust specifically — a different kind of trust, arising from a will or a deed of variation, has its own registration deadline (see the Trust Registration Service page for that).

A declaration of trust is a written record of beneficial ownership shares, distinct from legal title. Section 53(1)(b) of the Law of Property Act 1925 is the statutory anchor for why it has to be in writing at all: s.53(1)(b) LPA 1925 states that “a declaration of trust respecting any land or any interest therein must be manifested and proved by some writing signed by some person who is able to declare such trust or by his will.”

That single requirement is why the exact wording matters — a purely verbal agreement won't create an enforceable express trust of land. It leaves each owner arguing later that a constructive trust arose from what was said and done, which is the slower, less certain route the document exists to avoid (see §VII and FAQ 8 below). The rest of the modern framework for land held on trust — TOLATA 1996 — came into force on 1 January 1997 (confirmed against its own commencement order, SI 1996/2974), replacing the older trust-for-sale regime and giving courts specific powers to resolve disputes over land held this way.

Most people who need a declaration of trust fall into one of three situations. each turns on the same underlying problem: whoever's name is on the title doesn't, by itself, say who owns what.

Publicly advertised fixed fees for a straightforward declaration of trust commonly sit between roughly £250 and £900. a synthesis, as at 3 September 2026, of several UK firms' own published pricing, not a single sourced statistic — no one firm sets the market, and the range should be read as “commonly quoted between” rather than an average. Firms quote this fee before or after VAT differently — check which when comparing quotes.

The real driver of price is the shape of the deed, not its length. A simple fixed-share deed — say, a straight 60/40 split with no repayment terms — sits at the low end. A floating-share structure costs more: unequal ongoing mortgage payments, repayment-on-sale waterfalls, valuation mechanisms, or built-in dispute provisions all mean more has to be drafted correctly for the document to survive being tested later. Disbursements are typically few beyond the deed itself — see §V for the Land Registry side, which in most cases costs nothing at all.

A declaration of trust that only states the ownership percentages is doing half the job. a properly drafted one typically records four further things.

• The exact ownership shares and how they were calculated.
• Each co-owner's financial contribution — deposit, ongoing mortgage payments, capital improvements — and whether that record is fixed at outset or updates over time.
• Who is responsible for the mortgage, and what happens if one owner stops paying their share.
• What happens on sale — how the proceeds are split, and whether one owner has a right of first refusal to buy the other out.

The declaration of trust itself isn't registered at HM Land Registry. but if the property is held as tenants in common, a Form A restriction normally is — because a surviving sole owner can no longer give a valid receipt for money on a later sale without one.

Since 1925 it has been legally impossible for two or more people to hold the legal title to land as tenants in common — the legal estate is always held as joint tenants, whatever the co-owners agreed about their beneficial shares (HM Land Registry Practice Guide 24). The Form A restriction is what protects that split: it flags on the register that a buyer must pay two trustees, not one, for their payment to overreach the beneficial interests properly. It's usually applied for on Form RX1, or set out at the point of purchase via the transfer form.

Usually not, if no money or value changes hands between the co-owners. The rules are specific about the case that catches people out: no cash changes hands, but a share of the existing mortgage does.

Stamp Duty Land Tax is charged on chargeable consideration — and GOV.UK's own guidance is clear that taking on responsibility for someone else's share of an existing mortgage counts as chargeable consideration, even though no cash is paid directly. HMRC's worked example: if one owner takes on the other's half of a mortgage, the amount of debt assumed goes into the SDLT calculation as if it were cash paid.

A declaration of trust records who owns the property — it doesn't cover everything a co-owning household might want settled. Three things it deliberately doesn't do.

Checked directly against GOV.UK, HM Land Registry's own guidance, and legislation.gov.uk on 3 September 2026. This page is information about how the rules work, not advice on your situation — for a declaration of trust that needs to hold up if it's ever challenged, take advice from a solicitor before relying on anything stated here.

Three ways to act on this, depending on where you are.

One reader is buying a property with someone else right now and wants the shares written down properly. Another already owns jointly and wants to check whether a trust of any kind now needs registering. A third is redirecting an inheritance and needs the property side of that done correctly too.
