My buyer changed solicitors mid-sale. Should I worry?

Your phone buzzes and the agent tells you the buyer has instructed a different solicitor. After weeks of waiting, it lands like a warning. In most cases it is the opposite of one.

A buyer who is walking away does not pay a second firm to take the file on. They simply stop replying.

Why do buyers change solicitors partway through?

Conveyancing is the legal work of transferring ownership of a property from a seller to a buyer. It is slow by nature, and it has got slower: the median UK transaction now runs at roughly 200 to 205 days from offer to completion.

Against that backdrop, the usual reasons are ordinary ones.

• Unanswered calls and emails, which is by far the most common trigger.
• The original firm turned out to be on a high-volume, low-cost model with a caseload the buyer's file was lost inside.
• The lender does not accept the firm on its conveyancing panel, so the buyer had no choice.
• A conflict of interest or a staffing change at the original firm.
• The buyer's broker or family recommended someone they trust, and they lost patience.

How much delay does a solicitor switch actually add?

Expect weeks rather than days, and expect the clock to depend on the buyer, not on you. The new firm has to request the file through a signed form of authority, and the original firm will usually hold it until its invoice for work already done is settled.

Once the file arrives, a conveyancer cannot rely on another firm's investigations. They have to satisfy themselves that the title, the searches and the enquiries are in order, which duplicates part of the work.

What should I do about it?

1. 1. Ask why, through the agent, today

   A buyer frustrated by silence from their old firm will tell you so plainly. A vague or evasive answer is the thing to note, not the switch itself.

2. 2. Get the new firm's name and confirm they are formally instructed

   Instructed means the buyer has signed the client care letter and the firm has opened the file. Until that has happened there is no new solicitor, only an intention to appoint one.

3. 3. Ask whether the searches transfer

   Searches are the enquiries made of the local authority, water company and environment records about the property. If the new firm can accept the existing set, you save both weeks and the buyer's money; if not, the buyer is paying twice, which is worth knowing.

4. 4. Check the mortgage offer expiry date

   A mortgage offer is valid for a fixed period. Given the average mortgage rate rose from 4.65% in June to 4.75% in July 2026, an offer that lapses may be replaced by a dearer and smaller one. This is the single most useful date in the whole transaction.

5. 5. Have your own solicitor make direct contact

   Firm to firm is faster than agent to buyer to firm. Ask yours to introduce themselves to the new conveyancer and agree what is outstanding, so nothing waits on a chain of messages.

6. 6. Set a review date rather than an ultimatum

   Agree with your agent a date, three or four weeks out, at which you reassess. It keeps you in control without putting pressure on a buyer who is probably as frustrated as you are.

7. 7. Keep your own costs in step with theirs

   Hold off on further irreversible spending until the new firm is instructed and the file has moved. Momentum on your side is cheap; large outlays before the buyer has re-committed are not.

A buyer who pays a second firm to take the file on is a buyer still trying to buy.

Should I put the house back on the market?

Not on the strength of a solicitor change alone. Around one in four agreed UK sales collapsed before completion in the first quarter of 2026, at a fall-through rate of 23.7%, and the leading recorded causes were survey issues at 37.5% and buyers changing their minds at 31.25%. Switching conveyancer does not appear among the main causes.

Note also that 38% of collapses happen within the first four weeks of a sale being agreed. If your buyer is well past that point and is still spending money on the purchase, the odds are on your side. Remarketing now would trade a buyer who is invested for a market where sales agreed were 9% lower than a year earlier in the four weeks to 19 July 2026.

When is a switch genuinely a bad sign?

• It happens after exchange of contracts, where a missed completion date can carry financial penalties.
• Weeks pass and no new firm is actually instructed, only discussed.
• The buyer goes quiet at the same time, rather than explaining themselves.
• The switch follows a survey or a down valuation, which suggests the real conversation is about price rather than service.
• Their mortgage offer expires before the new firm can realistically be ready.

Keeping control of it

You cannot choose your buyer's solicitor, and you should not try. What you can do is know the two dates that matter, the mortgage offer expiry and your own review date, and make sure your side is never the one holding things up.
