This is a legal document that clearly records everyone’s financial contributions from the get-go. In this guide, we explain what a Deed of Trust involves, why it matters, and how it can help protect your finances.

What is a Deed of Trust?

A Deed of Trust, also known as a declaration of trust, is a legally binding document which records each owner’s financial share in the property and defines how co-owners divide the sale proceeds.

It’s particularly useful if you’re buying with a partner, friend, or family member and haven’t put in equal amounts. Rather than relying on a verbal agreement or assuming everyone involved will remember the details the same way, a Deed of Trust puts it in writing so everyone knows exactly where they stand.

In this article:  

When do I need a Deed of Trust?

You may need a Deed of Trust when two or more people buy a property together, but don’t contribute equally, and want that difference reflected in writing. Having a Deed of Trust is especially useful if you want to protect your financial interests should circumstances change further down the line.

A Deed of Trust can help a range of other situations, such as:

Unequal deposits

This is where one buyer puts down a larger cash sum than the other.

Family contributions

Parents or family members help fund the purchase through gifted deposits and want their contribution recognised.

Changing ownership shares

You'd like to set out ownership shares up front or update them later if your situation changes.

Unmarried couples

Partners buying together who want clarity over what each person owns, rather than relying on marital rights that don't apply to them.

Friends buying together

Where you want it clear from the outset who owns what, particularly if a dispute were ever to arise.

Investment properties

Co-investors who want their ownership shares set out clearly, along with custom rules for splitting rental income and sales profits. This is especially useful if you're going into a buy-to-let property with someone else, since it can clarify who's entitled to what share of the rental income, as well as the proceeds from any future sale.

Why is a Deed of Trust important?

Buying a home with someone else is exciting, but money matters can get complicated fast, especially if you're not contributing equally. Without having something in writing, you're relying completely on memory, goodwill, and the hope that nothing changes. A Deed of Trust removes that risk, giving you protection and peace of mind from day one. Having a Deed of Trust in place comes with some other key advantages:

  • Protects your contributions: If you've put in a bigger deposit for renovations, or contributed unevenly in any way, a Deed of Trust ensures you get back what you're rightfully owed, not just an equal split by default.

  • Avoids disputes: Having a clear agreed record means there's no room for arguments or uncomfortable situations, even years down the line.

  • Provides legal certainty: As a legally binding document, a Deed of Trust holds up in court if it ever comes to that, giving you solid ground rather than a "he said, she said" situation.

  • Prevents misunderstandings: Getting a document in writing as early on as possible means everyone's clear on where they stand.

What does a Deed of Trust include?

Rather than just stating who owns what, a Deed of Trust goes further by recording each person's beneficial ownership, how deposits and mortgage payments are split, and what happens to the money if the property is ever sold or one owner wants to buy the other out. Overall, it explains exactly what you're entitled to and when.

A Deed of Trust includes several key financial elements:

Beneficial ownership

A beneficial ownership is your right to the financial value of a property, even if your name isn't on the official title deeds. This includes a share of any rental income and a share of the proceeds if the property is sold.

It's different from legal ownership, which is simply whose name appears on the property's title. You can hold a beneficial interest without being a legal owner, and there's no limit on how many people can hold one.

Deposits

A Deed of Trust records exactly how much each person contributed towards the initial deposit of the property. This could include savings built up through a Lifetime ISA, which many buyers use towards their deposit with the added benefit of a government bonus. If the deposit contributions made weren't equal, it can set out that the person who paid more, gets that extra amount back first if the property is sold, before any remaining money is split between the owners.

Mortgage payments

Ongoing mortgage payments, including interest and capital repayments, can also be recorded within a Deed of Trust. It's worth noting that being named on the mortgage isn't the same as being a beneficial owner where you can contribute more towards monthly payments without being named a borrow, and a Deed of Trust is exactly what's used to reflect that. Any extra contributions made over time can then be factored into how the proceeds are divided if the property is sold.

Sale proceeds

When a property is sold the proceeds aren't automatically split down the middle. A Deed of Trust sets out exactly how that money should be divided between owners. Once the mortgage, fees, and other expenses have been paid off, the remaining net cash is divided according to what's been agreed, whether that's fixed percentages, a return on the initial deposit, or a custom formula written into the deed itself. For example:

Emma and James buy a property together for £400,000. Emma puts in a £70,000 deposit, whilst James contributes £20,000, and they agree to split the mortgage payments equally. Their Deed of Trust states that if the property is sold, Emma will receive her extra £50,000 back first, reflecting the difference in their deposits, before any remaining equity is split equally between them.

This way, both Emma and James’ contributions are properly recognised, and there’s no ambiguity over who’s owed what if they ever decide to sell.

Buy-out arrangements

A buy-out arrangement acts as a pre-agreed rulebook, dictating how one co-owner can buy the other’s share. This typically covers:  

  • Trigger events: the specific circumstances that can set the process in motion, such as relationship breakdown, one party voluntarily wanting to leave, an owner’s incapacitation or death, or a deadlock where co-owners can’t agree on how the property is managed.

  • Valuation method: how the property’s value is assessed at the time, including who carries it out, such as an agreed local estate agent or independent surveyor, when the valuation takes place, and how any disagreement over the figure would be resolved.

  • Buy-out price calculation: working out what’s owed to the departing owner by returning their original deposit or any capital improvements they’ve paid for, deducting the outstanding mortgage and selling costs, then applying their exact ownership share to what’s left.

  • Payment terms: the timeframe agreed for completing the buy-out, whether the remaining owner pays as a cash buyer or through a remortgage, and what happens if the buyer can’t secure the funds in time.

Deed of Trust: The process

So how do you actually get a Deed of Trust? In short, it involves agreeing on property shares with your co-owners, hiring a solicitor to draft the legal terms, and signing the document before an independent witness. This can be done at any point during a property purchase or at any point later. Here’s a closer look at each step:

Discuss and agree the details with your co-owners

Sit down with everyone involved and talk through how you want to split ownership of the property. This means agreeing who’s contributing what towards the deposit, mortgage payments, and any renovations or repairs, so there’s a clear and shared understanding before anything is put in writing.  

Instruct a solicitor

Contact a property solicitor or conveyancer and ask them to draft the formal document based on what you’ve agreed. If you’re setting one up after you’ve already bought the property, you’ll usually need an up-to-date valuation first so that the deed reflects the property’s current worth.

Review the draft carefully

Once your solicitor sends over the draft, read it thoroughly and check it matches exactly what you and your co-owners agreed. If anything’s unclear, feels off, or doesn’t match your discussion, raise it with your solicitor straight away as it’s much easier to fix at this stage before everything is signed.

Sign in front of a witness

To make the deed legally binding, it needs to be signed in front of an independent witness. Ideally this is someone who’s over 18, isn’t related to you, and has no financial interest in the property. This is what makes it a formal “deed” rather than just a regular signed agreement.

Keep it safe

Registering your deed with HM Land Registry is optional, but it can offer extra protection by creating public record of your agreement. If you’d rather not register it, make sure to keep the signed original somewhere safe with your other important property documents.

What are the different types of Deed of Trust?

There are two main types of Deed of Trust to choose from, depending on how you want your ownership shares to work. Here’s what each one means and which situations they suit best.

Fixed share

A fixed share deed of trust sets permanent ownership percentages or specific cash amounts for each co-owner right from the start, for example a 60/40 split, or a fixed sum returned to whoever paid the larger deposit amount before splitting the rest equally. Whatever has been agreed stays exactly the same when the property is eventually sold.

This is usually set up alongside owning the property as “tenants in common” rather than “joint tenants”, as this allows each person to hold a separate share rather than owning the property equally by default.

However, it’s important to consider that the shares do not change if one person later pays more for repairs, renovations, or mortgage instalments, so if your circumstances change drastically, you’ll need to re-write or update the deed to reflect this.

Floating share

A floating share deed of trust works differently to a fixed share. Instead of setting ownership percentages permanently, your share can grow over time based on what you contribute, such as mortgage payments, major renovations, or unequal deposit. For example, if you start off by owning 50/50, but you go on to pay a larger share of the mortgage over several years, your percentage could increase to reflect that. Day-to-day costs like household bills or routine maintenance don’t usually count towards this, only genuine capital contributions that add real value to the property.

Floating shares tend to suit longer-term situations where contributions are likely to change, since they reward whoever pays more towards the property over time, rather than locking everyone into their original split. However, this flexibility comes with more to manage as you will need to keep clear records of who’s paid what, and agree a precise formula from the outset, to avoid disagreements when it comes to working out the final shares.

Deed of Trust vs Joint Tenants vs Tenants in Common

Joint Tenants and Tenants in Common describe how you legally own the property with someone else. A Deed of Trust is a separate document that sits alongside Tenants in Common, recording exactly what each person’s financial share is. Here’s how they compare:

Feature

Joint Tenants

Tenants in Common

Ownership / shares

Each owner effectively owns 100% of the property jointly with the other owner

Each owner holds a specific share of the property, e.g. 50/50 or unequal splits like 70/30 based on deposits

Right of survivorship

If one owner dies, their share automatically passes to the surviving owner. You cannot leave your share to someone else in a will  

If an owner dies, their share does not go to the other owner. It goes to whoever is named in the will

Can you record unequal financial contributions?

No, ownership is equal by default

Yes, typically alongside a Deed of Trust as a layer of protection

Best for

Married couples or long-term partners who want a simple, shared arrangement

Friends, family members, or partners putting in unequal amounts of money

Can a Deed of Trust be challenged?  

Although it’s a legally binding document, a Deed of Trust isn’t completely untouchable. A court can step in and set it aside, change, or disregard it if specific legal grounds are proven. The grounds for challenging a Deed of Trust are:

  • Fraud or forgery: a signature is fake, or someone was deliberately tricked into signing

  • Undue influence: unfair pressure or control was used over someone vulnerable to force their signature

  • Duress: someone was threatened, intimidated, or heavily pressured into signing

  • Mistake: the written document doesn’t match what both people agreed to

  • Misrepresentation: one person was given false or misleading information before signing, whether that was deliberate (fraudulent), careless (negligent), or completely unintentional (innocent)

How much does a Deed of Trust cost?  

A Deed of Trust is typically drafted and prepared by a qualified solicitor or a conveyancer. Drafting a Deed of Trust can cost anywhere between £150 - £1,200 plus VAT, depending on the complexity of the agreement and the solicitor / conveyancer used. The total cost for a Deed of Trust is broken down into the following:

Basic or standard deeds

A straightforward, fixed-fee arrangement can cost anywhere between £150 - £500+. This can be for anything such as protecting unequal deposit contributions or defining specific percentage splits between co-owners.

Bespoke or complex deeds

For properties with complicated financial arrangements, multiple contributors, or floating shares, this can range between £500 - £1,200+.

Disbursements

A land registry restriction is an entry added to the property’s title at the HM Land Registry. It helps to protect the terms of the Deed of Trust by ensuring certain conditions are met before the property is sold or transferred.

In this case, budgeting an additional £20 - £40 is highly recommended.

Tips for reducing the costs where possible  

Use your conveyancer

You can save time and money by arranging a Deed of Trust during the conveyancing process, rather than adding one after you’ve completed your purchase. If you think you may need a Deed of Trust, let your conveyancer know as early as possible so they can prepare the necessary documents alongside your property transaction.

Compare quotes  

If you’re arranging a standalone Deed of Trust, it’s worth comparing quotes before you choose a conveyancer or solicitor. Many firms offer free, no-obligation quotes, so you can compare costs and services to find the right option for you.

What happens next?   

Once your Deed of Trust has been signed and witnessed, it then becomes a legally binding agreement between the co-owners. However, there are a few important steps to consider afterwards to help ensure the agreement continues to protect everyone involved:

Registering a restriction with HM Land Registry

Your conveyancer or solicitor may recommend registering a restriction with HM Land Registry. This places a note on the property title, helping to ensure the terms of the Deed of Trust are considered if the property is ever sold or transferred in the future.

The restriction does not change who owns the property, but it helps to protect the agreement by making sure the correct legal steps are followed before any changes can be made to the title.

Keeping your Deed of Trust safe  

Your original signed Deed of Trust is an important legal document, so it should be stored safely. Your solicitor or conveyancer may be able to keep a copy on file, but you should also keep a copy with the rest of your important property documents.

Make sure all co-owners have access to a copy so everyone understands the agreed ownership shares and responsibilities.

Review your will  

A Deed of Trust sets out your financial interest in the property during your lifetime, but it does not replace a will. If you own a share of a property, it’s important to make sure your will reflects your wishes and explains who you want your share to go to if you pass away.

Keeping your will and Deed of Trust up to date can help provide clarity for your loved ones and avoid potential complications in the future.

Review your Deed of Trust if circumstances change

Your circumstances may change over time, so it’s worth reviewing your Deed of Trust if there are significant changes, such as:

  • One owner contributing more towards the mortgage or property improvements

  • Someone else becomes an owner

  • Changes to your relationship or living arrangements

  • Changes to how the property is used

If your circumstances change, speak to your conveyancer or solicitor about whether your deed of trust needs updating.
