How much does a deed of trust cost UK?

A deed of trust typically costs £200–£500 if done through a solicitor as part of a property purchase. If created separately after purchase, it may cost £300–£800. Online legal services offer basic templates from £50–£150, but personalised legal advice is recommended for significant amounts of money.

Is a deed of trust legally binding UK?

Yes — a deed of trust is a legally binding document, provided it is properly executed (signed, witnessed, and ideally registered at the Land Registry as a restriction). It records the agreed ownership shares and can be enforced through the courts if there is a dispute. It can be overridden by a court order in divorce proceedings, but for unmarried couples it is the primary evidence of ownership shares.

Do married couples need a deed of trust?

Married couples rarely need a deed of trust because the court has wide powers to divide assets in a divorce regardless of who paid what. However, it can still be useful if one spouse is contributing significantly more and you want to document this for clarity. For unmarried couples, a deed of trust is far more important because there is no 'financial settlement' process outside of marriage.

Q: What is a deed of trust for property UK?

A deed of trust (also called a declaration of trust) is a legal document that sets out who owns what share of a property. It is particularly important when two or more people buy a property together but contribute unequal amounts towards the deposit, mortgage, or running costs. Without a deed of trust, the default position can lead to disputes about ownership shares.

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

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

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.

Registering at the Land Registry

Cost	£40 (Form RX1)
How	Your solicitor submits the restriction to the Land Registry
What it prevents	The property cannot be sold, transferred, or mortgaged without the consent of all named parties
Is it required?	Not legally required but strongly recommended

When Parents Help with the Deposit

Arrangement	Deed of trust should record
Gift to child	That it is a gift with no repayment obligation — child’s share reflects the gift
Loan to child	The loan amount, repayment terms, and interest (if any)
Investment (parent holds an ownership share)	Parent’s percentage ownership and what happens when the property is sold
Gift to couple	Who the gift is intended for — one person or both

Mortgage Lender Requirements

Detail	Information
Lenders need to know about the deed of trust	It creates a beneficial interest — this must be declared
Impact on the mortgage?	Usually none, provided all parties agree
Gift vs loan	Lenders prefer gifts (no repayment affects affordability) — loans may reduce borrowing capacity
Gifted deposit letter	Most lenders require a letter confirming the gift with no repayment expected

Changing or Ending a Deed of Trust

Situation	Process
Both parties agree to change the terms	Create a new deed of trust or a deed of variation — both should take independent legal advice
Property is sold	The deed of trust governs how the proceeds are split
One party wants to buy the other out	Independent valuation, then follow the buyout provisions in the deed
Relationship breakdown (unmarried)	The deed of trust determines each person’s share — if there is a dispute, mediation then court
Divorce	The court can override the deed of trust as part of the financial settlement
