Should separating co-buyers use separate solicitors?

Yes, in most cases. If you're buying a home jointly and the relationship between co-buyers has broken down, or you have unequal contributions, gifts, or existing disagreements, separate solicitors are the safer route. The Solicitors Regulation Authority and Law Society treat conveyancing as a poor fit for one firm acting for multiple buyers whenever interests could diverge, and residential purchases involving separated or separating parties almost always carry that risk.

There are narrow exceptions. A single firm can sometimes act for both parties where interests are genuinely aligned and a proper conflict check has been documented, but that scenario is rare once a relationship has broken down.

Your immediate next steps:

• Ask any firm in writing to confirm whether they've run a conflict check and what it found
• Gather proof of who paid what: bank statements, gift letters, transfer records
• Instruct independent legal advice if contributions are unequal, gifts are involved, or you disagree on ownership shares
• Ask specifically about HM Land Registry panel 10 and whether a Form A restriction will be needed

Key Takeaways

Separated or separating co-buyers need separate solicitors in almost every case, backed by a written declaration of trust and a correctly completed TR1 panel 10.

Separate solicitors for a joint purchase: what the rules actually say

The starting point isn't preference, it's regulation. Under SRA and Law Society guidance, a solicitor must decline to act where there's a conflict of interest between clients, or a significant risk of one arising. The exception, sometimes called "substantially common interest," only applies where clients share a clearly aligned objective with no realistic prospect of dispute. A joint purchase between separated partners rarely meets that bar, because the moment shares, contributions, or exit terms differ even slightly, interests split.

That's why separate legal representation for buying property is the default recommendation once a relationship has ended, is ending, or was never on equal financial footing to begin with. One firm acting for both of you might save a bit of money upfront, but it puts the solicitor in an impossible position the moment a disagreement surfaces.

Certain situations should trigger separate solicitors automatically, regardless of how amicable things feel right now:

• One person is contributing significantly more towards the deposit or mortgage
• Money has been gifted by a parent or relative to one buyer only
• One party previously held power of attorney or managed the other's finances
• The relationship has broken down, even if the purchase is proceeding
• Your mortgage lender specifically requires independent advice for one party

A proper conflict check in conveyancing isn't a box-ticking exercise. The firm should document its reasoning, record what checks were made, and be willing to explain that in writing if asked. Firms that brush past this, or treat it as a formality, are one of the clearest warning signs in the whole process.

Pro Tip: Before instructing anyone, ask the solicitor directly: "Have you acted for both parties on a joint purchase before, and what happens if we later disagree?" Their answer tells you more than any brochure will.

How ownership gets recorded: legal estate, beneficial interest, and the TR1

Here's where a lot of confusion starts — understanding different property types and ownership forms helps clarify what gets recorded where. The legal estate, the bit registered at HM Land Registry, is always held as joint tenants when there's more than one registered owner. That's a fixed rule. What it doesn't automatically record is beneficial interest, meaning who actually owns what share of the property's value.

Beneficial interest is decided separately, and it's recorded on panel 10 of the TR1 transfer form when the property changes hands. You'll choose one of three options there: joint tenants (equal shares, with survivorship rules), tenants in common in equal shares, or tenants in common in unequal shares. Choosing tenants in common with unequal shares triggers a Form A restriction on the register, flagging that beneficial ownership isn't straightforward joint ownership.

HM Land Registry's own guidance makes clear that the register rarely states the actual percentage shares, even where a Form A restriction appears. It signals that shares exist without specifying them.

This is where things go wrong more often than people expect. If panel 10 is left blank or filled in ambiguously, the Land Registry may default to entering a Form A restriction without the underlying shares being clear anywhere. That's a genuinely common pitfall, and correcting it later usually means instructing a solicitor to draft a deed retrospectively, sometimes years after the purchase, once memories of who paid what have already faded.

If you're unsure how your own property is recorded, check your title register directly through HM Land Registry, or ask your solicitor to pull it. If you want to understand the practical difference before you buy, our guide on tenants in common versus joint tenancy walks through it with worked examples.

What should a declaration of trust actually cover?

A declaration of trust, sometimes called a deed of trust, is the document that does the job the TR1 can't: it spells out exactly who owns what, why, and what happens if things change. Solicitors who specialise in joint purchases treat this as standard practice rather than an optional extra, particularly for friends, siblings, or unmarried couples buying together.

A well-drafted deed should include:

1. Percentage shares each party holds in the beneficial interest, expressed as a fixed figure
2. A record of contributions, including deposit amounts, mortgage repayment splits, and any lump sums paid later
3. Cost apportionment, covering who pays for repairs, ground rent, service charges, or major works
4. Sale and buy-out mechanics, setting out how a departing party is bought out and how a valuation is agreed
5. Dispute resolution, ideally naming mediation before either party can apply to court

Solicitors will typically ask for evidence to back up whatever the deed states, bank statements showing deposit payments, and signed gift letters where a parent or relative has contributed money without expecting it back. Where a gift is involved, the person receiving it is often asked to get independent legal advice before accepting it, precisely to head off future arguments about whether it was really a gift or a loan.

Before you instruct a solicitor, it helps to have gathered: proof of ID, bank records showing your deposit source, any gift letters, and a rough note of what shares you and your co-buyer expect to hold. Our practical guide for co-buyers sets out sample clauses if you want a starting point.

Pro Tip: Never rely on a verbal agreement about shares, even with someone you trust completely. Courts can only infer contributions from evidence years later, and that process is slow, expensive, and uncertain compared with a deed signed on day one.

What happens legally when co-owners separate?

When a relationship ends after you've bought together, the legal route depends on what you both want. If you're joint tenants and want to move to fixed, unequal shares, you'll need to sever the joint tenancy first, a fairly simple written notice, then record the new arrangement via a transfer of equity or fresh declaration of trust.

Buying a co-owner out involves more moving parts than people expect:

• The remaining party usually needs to re-mortgage or get lender consent to remove the other name from the mortgage
• The lender will assess affordability independently, as if it were a fresh application in many cases
• A transfer of equity document formally moves the departing party's share
• Stamp Duty Land Tax can apply to the buyout, depending on the value exchanged

Where you can't agree, the Trusts of Land and Appointment of Trustees Act 1996 gives either party the right to apply to court for an order for sale or to resolve disputes about occupation and beneficial shares. This route exists, but it's slow and costly compared with resolving things by agreement, and solicitors will almost always push negotiation and mediation first, then a deed variation, then lender discussions, with court reserved as the last resort. If you're stuck because a co-owner won't cooperate, our piece on what to do when a co-owner refuses to sell covers the practical escalation steps.

What does it cost to instruct separate solicitors, and how long does it take?

Two sets of solicitors means two sets of fees, but the increase is usually smaller than people fear, because most of the shared costs (searches, Land Registry fees, the actual conveyancing of the property itself) don't double. What you're paying twice for is the advisory time: reviewing the deed, checking the TR1, and confirming each party understands what they're signing.

Typical elements you'll budget for:

• Standard conveyancing fees, charged separately by each firm
• Search fees and HM Land Registry registration fees, usually split or paid by the buyer as agreed
• A separate, often modest, fee for independent legal advice where a gift or unequal contribution is involved
• Drafting costs for the declaration of trust, sometimes bundled into the main fee

From the offer being accepted to registration, expect a few weeks in a straightforward case, with drafting and reviewing the declaration of trust adding time if it's negotiated late rather than agreed early. The single biggest cost-saver is agreeing the shares and deed terms before instructing solicitors, not during. Fixed-fee quotes, a clear scope from the outset, and having your contribution evidence ready all cut back-and-forth considerably.

What documents and questions should you have ready?

Before you even pick up the phone to a solicitor, a bit of preparation saves real time later. Have these ready:

1. Photo ID and proof of address for both buyers
2. Bank statements showing the source of each deposit contribution
3. Any gift letters from family members, signed and dated
4. A written note of the ownership shares you both expect, even if informal at this stage

When you speak to a solicitor, ask directly: have they run a conflict check for this transaction, have they drafted declarations of trust before, and how do they handle file management if the two sides later need separate advice? Their answers, and how readily they give them, tell you a great deal.

Cohaus supports matched co-buyers through this exact process, with deed of trust templates, partner solicitor introductions, and lessons drawn from the community forums where co-buyers share what worked and what didn't. If contributions are unequal, or a gift is involved, or one of you already feels uneasy about the shares being discussed, that's the moment to pause and get separate advice rather than push ahead.

Pro Tip: Write down your expected ownership split before your first solicitor call, even roughly. Solicitors work far faster from a starting figure than from a blank page.

Practical mistakes we see and how to avoid them

The mistakes that cause real damage are rarely dramatic. They're the quiet ones: no declaration of trust because "we trust each other," a TR1 signed without really discussing panel 10, a verbal agreement about who gets what if things end. None of these feel risky at the time. They only become expensive once a relationship changes and there's nothing written down to point to.

The fix is almost boringly simple. Get the shares agreed and written into a deed before completion, not after a disagreement starts. Ask your solicitor plainly what happens if things go wrong. Use resources like Cohaus's deed of trust breakdown to know what a proper deed should contain before you sign anything.

How Cohaus helps you get matched solicitors, deed templates, and deposit protections

Cohaus exists for exactly the situation this guide has walked through: buying with someone else, needing clarity on shares and legal protections, and wanting a structured process instead of guesswork. Cohaus is the alternative to piecing this together alone, connecting you with partner solicitor introductions, ready-made deed of trust templates, and shared deposit handling designed with joint buyers' actual risks in mind.

Getting started is straightforward: sign up, gather the documents outlined above, and request a partner solicitor introduction through the platform. An initial conversation typically covers your proposed ownership shares, whether independent advice is needed for either party, and what the deed of trust should record before you go any further. If you're currently renting, saving, or feeling locked out of a joint purchase because the legal side feels daunting, Cohaus is built to make that first step less uncertain.
