Can Buyer and Seller Use the Same Solicitor in the UK?

Property transactions raise this question more often than most people expect, particularly in family sales, small chains, or divorce settlements. The short answer is nuanced. Regulatory bodies permit it in limited circumstances, but strict conditions apply. This guide draws on how these rules actually play out in residential conveyancing practice, not just what the rulebooks say on paper.

In ordinary buyer-and-seller transactions, separate representation is usually appropriate because the parties’ interests can conflict, particularly on price, timing, and liability for defects. A solicitor may only act for both clients where the applicable conflict rules and exceptions are satisfied and the solicitor is satisfied that it is reasonable to do so.

It helps to separate two scenarios often conflated by homeowners searching can the same solicitor firm act for buyer and seller. The first is dual representation, where one solicitor or firm acts for both parties in a single linked sale and purchase. The second is an individual using one solicitor for their own sale and their own onward purchase, which is entirely standard and carries no conflict, since the same person is the client on both sides.

Dual Representation Rules Under SRA and CLC Regulations

The SRA Code of Conduct addresses conflicts of interest in Paragraphs 6.1 and 6.2. In general, a solicitor must not act where there is a conflict, or a significant risk of one. There are limited exceptions where the clients have a substantially common interest, or are competing for the same objective, provided the required conditions are met. Those conditions include informed consent in writing, appropriate safeguards for confidential information where necessary, and the solicitor being satisfied that it is reasonable to act for all the clients involved.

The Council for Licensed Conveyancers applies a comparable standard for licensed conveyancers, who handle a significant share of UK property transaction work outside traditional law firms. Both regulators converge on one core test: is there a genuine common interest, or merely an absence of open dispute? A seller wanting a quick completion and a buyer wanting full disclosure of defects are not “common interest” simply because both want the sale to complete.

Where dual representation is agreed, the conveyancing solicitor must obtain mandatory written informed consent from both parties, disclosing the conflict and its implications before accepting instructions. Impartiality must be demonstrable throughout, and the file must show that neither party received preferential advice.

Can Two Solicitors at the Same Firm Act for the Buyer and Seller?

Having different fee earners within the same firm does not automatically remove a conflict of interest. The firm must still comply with the applicable conflict and confidentiality rules and be satisfied that it is reasonable to act for both clients. Where confidential information needs to be protected, appropriate safeguards may also be required, such as separate files and restricted access between the two fee earners.

When Dual Representation Is Permitted (Common Scenarios)

Certain scenarios meet the “substantially common interest” threshold reliably:

• Property transfers between family members or spouses, where both parties want the same outcome and there is no genuine price negotiation.
• Agreed divorce transfers following a Financial Consent Order, where the court has already settled the terms.
• Transfers involving trusts and beneficiaries, where the trustee and beneficiary are effectively aligned.
• Developer or new-build purchases, where a solicitor recommended by the developer is offered to the buyer. A recommendation or panel arrangement does not automatically mean the same solicitor can act for both the developer and the buyer. The buyer should ask who the solicitor represents and whether independent representation is available, particularly given the potential for diverging interests over snagging issues, build quality, or contract variations.

Can the Same Solicitor Act for Both Parties in a Divorce?

This question, often searched as can the same solicitor act for both parties in a divorce, has a clear split answer. Non-contentious transfers carried out under an approved consent order are generally acceptable, because the financial terms have already been fixed by the court and there is nothing left to negotiate adversarially.

Where the spouses are involved in a contested financial dispute or are still negotiating the terms of selling a house during divorce, one solicitor should not normally act for both sides, because their interests are likely to conflict. Once there is disagreement over valuation, sale proceeds, or timing, one solicitor cannot properly advise both spouses without risking a breach of the duty of undivided loyalty.

The Mortgage Factor: Why Lenders Block Dual Representation

Mortgage lenders add a further layer of restriction beyond SRA rules. The UK Finance Lenders’ Handbook sets out requirements that generally expect the buyer’s solicitor to act independently of the seller in mortgaged transactions, to protect the lender’s security interest. The precise requirements can vary by lender, so it is worth checking the current Handbook entry, or the lender’s specific instructions, before agreeing to shared representation.

This is why should buyer and seller use the same solicitor questions usually resolve differently depending on financing. A cash purchase removes the additional requirements imposed by a mortgage lender, but it does not remove the solicitor’s professional obligations concerning conflicts of interest. Where a mortgage is involved, the lender’s own requirements must also be satisfied before a solicitor can act, and most panel-approved firms will decline joint instructions to remain compliant.

What Happens If a Conflict Arises Mid-Transaction?

Even legitimately arranged dual representation can break down. Common triggers include survey defects discovered after an offer, title disputes over boundaries or easements, or unexplained completion delays. Once an actual conflict emerges, SRA compliance requires the firm to withdraw from acting for at least one party, sometimes both.

This withdrawal carries real cost. At least one party typically needs to instruct a new conveyancing solicitor, and the new solicitor may need to repeat or update certain checks, review the existing property searches when buying a house and title documents, and carry out their own due diligence before proceeding. This can cause significant delay, because the new solicitor must review the transaction, verify information, and establish their own relationship with the client before progressing. In a chain, that delay can put the wider transaction at risk if a linked buyer or seller loses patience.

Do You Have to Use the Solicitor Recommended by an Estate Agent?

Estate agents and mortgage lenders may recommend solicitors, conveyancers, or other professionals. If the estate agent or lender receives a referral fee from the recommended provider, buyers and sellers should be told about it. There is no obligation to use the recommended firm, and choosing an independent legal representative is always an option.

Anyone considering the same firm recommended to both sides of a transaction should ask that firm directly whether it can act for both parties and how any potential conflict of interest would be handled, before giving instructions.

Pros and Cons of Using the Same Firm

Decision Checklist: Should You Use the Same Solicitor as Your Buyer/Seller?

Before agreeing to shared representation, consider the following:

• Is this a family transfer, agreed divorce settlement, or arm’s-length sale? Shared representation suits the first two far better than the third.
• Is a mortgage involved? If so, confirm with the lender whether joint instructions are acceptable at all.
• Is there a chain? Longer chains carry higher risk that when a buyer pulls out, dual representation complicates re-marketing and advice simultaneously.
• Has written informed consent been properly documented, not just verbally agreed?
• Would independent legal advice cost meaningfully more, given the transaction value and complexity?

In most straightforward residential sales, particularly where a mortgage or a chain is involved, independent solicitors remain the safer and more widely accepted route. Dual representation has a legitimate place, but only where the underlying relationship between the parties genuinely supports it.

FAQs:

1. Can a buyer and seller use the same solicitor in the UK?
Yes, in limited circumstances. A solicitor may act for both parties where conflict rules are satisfied, informed consent is obtained where required, and the solicitor considers joint representation reasonable.

2. Can two solicitors from the same firm act for the buyer and seller?
Possibly, but using different fee earners does not automatically remove a conflict. The firm must still comply with conflict and confidentiality rules and ensure both clients receive appropriate protection.

3. Can the same solicitor act for both parties in a divorce?
Sometimes, where a property transfer is non-contentious and follows agreed terms, such as an approved consent order. If the spouses are still disputing the sale, valuation or proceeds, separate legal advice is normally appropriate.

4. Can a buyer and seller use the same solicitor if there is a mortgage?
A mortgage can make dual representation more difficult because lenders may require the buyer’s solicitor to act independently. Always check the lender’s requirements before relying on the same solicitor for both parties.

5. What happens if a conflict of interest develops during conveyancing?
If a genuine conflict arises, the solicitor may have to stop acting for one or both parties. A new solicitor may then need to review the transaction and repeat or update checks, potentially causing delays.
