Buying a property with a partner, relative or friend can be an exciting step, but the legal paperwork does not always reflect the financial reality. A declaration of trust solicitor can record who has contributed what, who owns which share, and what should happen if the property is sold or one owner wishes to leave.

This is particularly valuable where buyers contribute unequal deposits, pay different amounts towards the mortgage, or have agreed that one person will receive more of the sale proceeds. Without a clear written agreement, a disagreement later can be expensive, stressful and difficult to resolve.

What is a declaration of trust?

A declaration of trust, sometimes called a deed of trust, is a legally binding document setting out the beneficial ownership of a property. The legal owners named on the title at HM Land Registry may not hold equal financial interests in the home. The declaration explains the arrangement behind the title.

For example, two people may buy a flat together but one contributes a £100,000 deposit while the other contributes £20,000. They may decide that their respective shares should reflect those contributions, rather than being split equally. Alternatively, they may agree to own the property 50/50 despite unequal contributions. The key point is that the intended arrangement is properly recorded.

The document can also deal with practical matters that are often left unspoken at the start of a purchase. It may state how mortgage payments, major repairs and improvements are to be treated, whether a contribution is a gift or a loan, and how sale proceeds will be divided.

A declaration of trust does not replace a will. If you want to control who receives your interest in a property after your death, you should also consider appropriate will planning. The right approach depends on how the property is owned and your wider family circumstances.

When should you instruct a declaration of trust solicitor?

The best time to prepare a declaration is before completion, while everyone understands and agrees the financial arrangement. It can be completed alongside the conveyancing process, allowing the property purchase and ownership arrangements to be dealt with together.

It may also be appropriate after a purchase. Perhaps one owner has paid for an extension, a parent has provided funds, or a couple’s circumstances have changed. A new agreement can be considered, provided all parties understand the effect of changing their interests and any lender requirements are addressed.

Common situations include unmarried couples purchasing a home, friends buying together, parents helping an adult child onto the property ladder, and business partners acquiring investment property. Married couples and civil partners can benefit too, although declarations of trust should be considered carefully alongside family law rights and any future financial settlement.

Where a parent provides a deposit, clarity is especially important. Is the money an outright gift? Is it a loan that must be repaid on sale? Does the parent acquire a beneficial share? Each option has different legal, practical and potentially tax consequences. A verbal understanding may feel sufficient within a family, but it can become a source of real conflict when circumstances change.

What should the document cover?

There is no single declaration that works for every co-owner. A well-drafted document should reflect the actual agreement rather than relying on a generic template. The more detailed the financial arrangements, the more important it is to obtain tailored advice.

A declaration commonly sets out the purchase price and deposit contributions, the beneficial percentage held by each owner, and how net sale proceeds will be divided after the mortgage, estate agent’s fees and conveyancing costs have been paid. It can explain whether later mortgage payments alter the agreed shares, and how capital used for renovations should be recognised.

It should also address what happens if one person wants to sell. This may include a process for offering their share to the other owner, agreeing a valuation, setting a timescale for a buyout, or placing the property on the market. Agreeing these points in advance is often far easier than negotiating them during a relationship breakdown or financial difficulty.

For some clients, the agreement will be straightforward: fixed shares that do not change. For others, a formula may be more suitable, particularly where contributions are expected to vary over time. Formula-based arrangements need careful drafting. They can appear fair at the outset but become confusing if they do not clearly define which payments count, how improvements are valued, or what happens if one owner stops contributing.

Why a declaration of trust solicitor matters

Online templates can look attractive because they appear quick and inexpensive. The difficulty is not simply completing a form. It is deciding what the agreement should say, ensuring it reflects the parties’ intentions, and considering the legal consequences of the chosen arrangement.

A solicitor can explain the difference between legal ownership and beneficial ownership, identify issues that may otherwise be missed, and draft terms that are specific enough to be useful if a dispute arises. This includes considering the mortgage lender’s position, the property title, the proposed ownership structure and whether a restriction should be entered on the register to help protect the arrangement.

Independent advice can be particularly important where one party is contributing substantially more than another, or where family members are funding a purchase. If the interests of those involved conflict, one solicitor may not be able to advise everyone. Separate legal advice helps ensure that each person understands the agreement they are signing and reduces the risk of later claims that they were pressured or misled.

A properly prepared declaration cannot guarantee that no disagreement will ever arise. It can, however, provide a clear starting point and strong evidence of what was agreed. That can make negotiations more focused and may reduce the need for costly litigation.

Declarations of trust and joint ownership

The way a property is held matters. Co-owners can hold a property as joint tenants or tenants in common. These terms can be confusing because they do not describe a tenancy arrangement.

Joint tenants own the whole property together and, on death, the deceased owner’s interest usually passes automatically to the survivor. Tenants in common hold distinct beneficial shares, which can be equal or unequal, and each person can usually leave their share under a will.

A declaration of trust is often used where owners are tenants in common, especially where they hold unequal shares. However, the correct structure depends on your objectives. Estate planning, family circumstances and the terms of any mortgage all need consideration. It is sensible to discuss the ownership structure before exchange of contracts rather than treating it as an afterthought.

Questions to resolve before signing

The most useful conversations happen before the document is drafted. Co-owners should be open about deposits, monthly payments, expected improvements and what each person considers fair if the property is sold. A solicitor can turn those discussions into precise legal terms.

You should be able to answer whether contributions are gifts, loans or investments; whether mortgage payments will affect ownership shares; and whether one owner can buy the other out. You should also consider what happens if a relationship ends, one owner loses their job, or a proposed sale cannot be agreed.

There is no universally fair answer. A fixed 50/50 split may be exactly right for a couple building a life together, even where one paid more initially. In another case, fixed unequal shares or a repayment of the original deposit may better reflect the parties’ intentions. The right document is the one that records a fully informed agreement, clearly and realistically.

Getting the timing and advice right

A declaration of trust should be treated as part of protecting a property investment, not as an awkward sign of distrust. Clear arrangements can protect relationships as much as finances because each person knows where they stand from the outset.

At White Horse Solicitors & Notary Public, clients can receive practical advice on declarations of trust alongside residential conveyancing and wider property planning. Addressing the detail early gives co-owners a clearer path forward, whatever the future brings.
