At a Glance
A Deed of Trust is a legally binding agreement that documents how property ownership and financial interests are divided among co-owners, particularly when contributions are unequal.
It helps reduce disputes by clarifying ownership shares, mortgage responsibilities and sale proceeds.
At the same time, independent legal advice is often recommended to ensure all parties fully understand the agreement and its financial implications.

Understanding a Deed of Trust
Buying property with another person can quickly become complicated when there are unequal financial contributions or differing ownership expectations.
Whether purchasing a home with your spouse or investing with friends, many buyers are unaware of how to clearly anftnd legally protect everyone’s interests.
This is where a Deed of Trust can help.
A Deed of Trust, also known as a Declaration of Trust, is a legally binding document that records the division of ownership of a property between co-owners.
It outlines who contributed how much and what happens if circumstances change, for instance, the distribution of proceeds in case of a sale.
Although it’s commonly used in the UK property market, many buyers are unsure how a Deed of Trust works. Another common query is whether a Deed of Trust requires ILA (Independent Legal Advice) before you sign one.
To make this simpler, this guide offers a detailed breakdown of what a deed of trust is, how it works, when it's useful, if you require ILA to create one and why legal advice is essential before signing.
How to Set Up and Register a Deed of Trust
In practice, a Deed of Trust works by formally documenting the agreement between co-owners regarding financial contributions and beneficial ownership rights.
In a Deed of Trust, you can find details including:
- The ownership percentage held by each party
- Deposit contributions
- Responsibility for paying mortgages
- Household expense arrangements
- What actions should be taken if the property is sold
- Procedures to follow if one owner wishes to exit the agreement
- How future increases in property value are divided
Once signed, the agreement is legally enforceable under English and Welsh law.
Many people are unsure how to set up and register a Deed of Trust. Here’s a quick outline of the process, applicable to most cases:
When Do You Draft a Deed of Trust?
The Deed of Trust is set up during the conveyancing process, before contracts are exchanged.
When Do You Sign the Deed of Trust?
The Deed is typically signed before the property purchase is completed, ensuring the agreement becomes legally effective upon the transfer of ownership.
Where is a Deed of Trust Registered?
In many cases, a Form A restriction is registered at the Land Registry alongside the property title.
Why Mortgage Lenders Care About Your Trust Deed
When ownership structures become complex, mortgage lenders become more cautious. This is also applicable when family members make deposit gifts, where lenders want to ensure that no third party gains rights that interfere with the lender’s security.
For example, if parents contribute £50,000 toward a deposit but are not named on the mortgage, questions arise:
- Whether the funds are a gift or a loan
- Whether parents expect repayment
- Whether they may claim an ownership interest
From the lender’s perspective, an undisclosed beneficial interest may create legal complications if the property is repossessed. This is why many lenders insist on gifted deposit declarations and an ILA for Deeds of Trust.
While ILA is not mandatory for a Deed of Trust, insisting on one can reduce the risk of future claims alleging undue influence or pressure, misrepresentation of ownership interests or an understanding that the agreement was unfair or invalid.
Can a Deed of Trust Be Changed or Overturned Post-Completion?
“Can a deed of trust be changed?” is another question people often ask.
The answer is yes, provided the changes are formally documented and agreed upon by all involved parties.
Any changes are commonly made through a Deed of Variation, a Deed of Revocation or a replacement Deed of Trust.
Is a Trust Deed a Good Idea for Joint Tenants or Tenants in Common?
In co-ownership, it’s important to understand the legal distinction between joint tenants and tenants in common. A Deed of Trust is almost always paired with a Tenants in Common structure.
Joint Tenants
Under a joint tenancy, both owners automatically have equal ownership, and there are no separate ownership shares. Here, the property automatically passes to the surviving owner if one owner passes away. This structure is common for married couples with fully shared finances.
Tenants in Common
Under tenants in common, owners can hold equal shares with beneficial interests specifically defined. Here, ownership can pass via a will rather than automatically.
This structure works better, especially for unequal deposits, parents contributing funds, differing investment ownership or parties needing financial safeguards. Form A restriction at the Land Registry is used here.
What Happens to the Equity If the Property Values Drop?
People often focus on property value appreciation, but declining values also need to be considered.
You can use a Deed of Trust to structure repayment arrangements in different ways.
Fixed Repayment Model
If person A contributes an extra £40,000 deposit, the Deed can state that they receive £40,000 back first upon sale, and the remaining equity is split equally.
Percentage Split Model
Consider a case where person A owns 70% and person B owns 30%. If the property’s value rises or falls, each party shares gains and losses proportionately.
During market downturns, this distinction becomes even more important because fixed repayment models can better protect initial contributions, while percentage models expose both parties proportionately to losses.
When Do You Actually Need a Deed of Trust?
A Deed of Trust is commonly used when:
- One party contributes a larger deposit
- Co-owners contribute different amounts towards mortgage payments
- Parents help children buy a property
- Friends buy an investment property together
- Unmarried couples buy a home jointly
- The involved parties want clarity over ownership percentages
To explain this further, let’s consider two scenarios.
Scenario A: Unequal Deposit Contributions
An unmarried couple buys a property together, with one contributing a 70% deposit and both splitting mortgage payments equally.
A Deed of Trust records the larger initial contribution and clarifies how future sale proceeds will be divided.
Scenario B: Parents Contributing a Deposit
Parents gift £50,000 towards their child’s home purchase but want reassurance that the money stays with their child if the relationship breaks down later.
Here, a Deed of Trust can clearly document the arrangement while meeting lender requirements.
In both these situations, signing a Deed of Trust can be a good idea.
