What Is a Deed of Trust for Property UK — Complete Guide

What a deed of trust is, when you need one for property in the UK, how it works, costs, and what to include. Essential guide for unmarried couples and unequal contributions.

A deed of trust is one of the most important documents you can have when buying property with another person — especially if you are not married. Here is when and why you need one.

What Is a Deed of Trust?

Detail Information
Also known as Declaration of trust, trust deed
What it does Records who owns what percentage of a property
When it is made Usually at the time of purchase (but can be created later)
Who needs one Anyone buying with another person and contributing unequal amounts
Legally binding? Yes — enforceable through the courts
Registered? Can (and should) be registered at the Land Registry as a restriction

When You Need a Deed of Trust

Situation Why you need it
Buying with a partner (unmarried) and paying unequal deposits Protects the person who paid more
Parents helping with the deposit Documents whether it is a gift or loan, and what share the parents (or their child) own
Buying with friends Clarifies ownership shares and obligations
One person paying the mortgage while the other contributes less Reflects actual financial contributions
Investing in someone else’s property Records your financial interest
Protecting assets you brought into a relationship Documents pre-existing equity

Joint Tenants vs Tenants in Common

Feature Joint tenants Tenants in common
Ownership shares Equal (always 50/50 regardless of contributions) Defined shares (can be any split)
Right of survivorship Yes — if one owner dies, the other automatically inherits No — each share passes according to their will
Deed of trust needed? Less relevant (shares are equal by definition) Essential — defines the actual ownership shares
Best for Married couples who want everything to pass to the survivor Unmarried couples, friends, investment partners
Severance Can be converted to tenants in common N/A

Most unmarried couples buying together should be tenants in common with a deed of trust.

What a Deed of Trust Should Cover

Section What to include
Ownership shares Each person’s percentage ownership
Deposit contributions Who paid what towards the deposit
How shares change over time Do mortgage payments change the shares? (Fixed shares vs floating shares)
Sale triggers When can a sale be forced? What happens if one person wants to sell and the other doesn’t?
Running costs Who pays the mortgage, insurance, maintenance, and what happens if one person stops paying?
Improvements Does spending on improvements change ownership shares?
Dispute resolution Mediation before legal action
Buyout provisions Can one person buy the other out? How is the price determined?
Death of an owner What happens to their share?

Fixed Shares vs Floating Shares

Type How it works Best for
Fixed shares Ownership shares stay the same regardless of who pays the mortgage over time Simple, clear, less administration
Floating shares Ownership shares change as each person makes mortgage payments or contributions Fairer if one person is paying significantly more over time

Fixed Share Example

Detail Person A Person B
Deposit contributed £40,000 £10,000
Mortgage payments Split 50/50 Split 50/50
Ownership share 60% 40%
On sale (house sells for £300,000) £180,000 £120,000

Floating Share Example

Detail Person A Person B
Deposit contributed £40,000 £10,000
Total mortgage paid (over 5 years) £30,000 £18,000
Total contribution £70,000 £28,000
Ownership share 71.4% 28.6%
On sale (house sells for £300,000, after repaying £152,000 mortgage balance) £105,700 (71.4% of £148,000 equity) £42,300 (28.6% of £148,000 equity)

Floating shares are fairer but require careful record-keeping and clear tracking methods in the deed.
