How quickly should you instruct a solicitor after winning at auction?
The moment the gavel falls, the clock starts ticking. If you’ve just won a property at auction, the single most important action you can take is to instruct a solicitor after winning at auction — and you need to do it today. Not tomorrow. Not after the weekend. Today.
Unlike a standard property purchase, where solicitors are instructed weeks before contracts are exchanged, auction purchases work in reverse. Contracts exchange at the fall of the hammer. From that point, you have a fixed, legally binding timeline to reach completion — and every day of delay increases your financial and legal exposure.
This guide explains exactly what happens after you win at auction, why your solicitor must be contacted immediately, what tasks need to be completed before the auction completion deadline, and what happens if things go wrong.
Why you must instruct a solicitor on the same day
Auction purchases are legally binding from the moment you win. The memorandum of sale is signed at the auction house, contracts are treated as exchanged, and the completion date is set — typically 14 or 28 days from auction day, as specified in the Special Conditions of Sale.
This is fundamentally different from a private treaty purchase. In a standard sale, solicitors are involved for weeks before exchange, conducting searches, reviewing title, and negotiating terms. At auction, all of that groundwork must happen after the hammer falls — within a very compressed timeframe.
That is why it is critical to instruct a solicitor after winning at auction on the very same day. If you already have an auction conveyancing solicitor lined up before the auction — which is strongly recommended — the process can begin almost immediately. If you have not yet instructed anyone, begin making calls the moment you leave the auction room.
You can read more about what to expect at every stage in the guide to what happens after the hammer falls, which walks through the key obligations for buyers from auction day through to completion.
Auction day guide: What happens after the hammer falls
What your auction conveyancing solicitor must do — and fast
Once instructed, your auction conveyancing solicitor will need to complete a significant amount of legal work before the auction completion deadline arrives. The tasks below are not optional extras — they are the core of the post-auction legal process.
Confirm the completion deadline
Your solicitor will check the Special Conditions of Sale to confirm whether completion is set at 14 or 28 days. This date is fixed and non-negotiable in the vast majority of auction transactions.
Request and review the auction pack
If a full auction pack review was not carried out before bidding, your solicitor will need to review it urgently after the hammer falls. This includes the title register, title plan, special conditions, searches, and any additional documentation provided by the seller.
Liaise with the seller’s solicitor
Your solicitor will contact the seller’s legal representative to obtain the draft transfer deed, raise any final requisitions, and confirm completion arrangements.
Order any outstanding searches
Depending on what was included in the auction pack, additional searches may be needed. These can take several days to return, so instructing your solicitor early is vital.
Manage finance and mortgage drawdown
If you are using a mortgage or bridging finance, your auction conveyancing solicitor will liaise with the lender to ensure funds are ready for transfer in time. Lenders also have their own requirements and timelines that must be factored in.
Prepare for registration at HM Land Registry
After completion, your solicitor will handle the registration of your ownership at HM Land Registry. This step protects your legal title to the property.
A detailed breakdown of what the timeline looks like — and when each of these tasks must happen — can be found in the buyers’ timeline and deadlines guide.
The risks of delaying your solicitor instruction
Missing or ignoring the urgency of instructing your solicitor is one of the most costly mistakes a buyer can make after winning at auction. The consequences of delay are not theoretical — they are written into the conditions of the contract you signed the moment the hammer fell.
You may miss the auction completion deadline
If your solicitor is instructed late and cannot complete the required legal work in time, you risk missing the completion date. This is treated as a breach of contract.
Daily interest charges apply immediately
Most auction contracts include a provision for the seller to charge daily interest from the day after the contractual completion date. These charges can amount to hundreds or thousands of pounds depending on the purchase price.
You could lose your deposit
If completion does not take place, the seller has the right to forfeit your 10% deposit. This is not a penalty that requires a court order — it is a contractual right exercisable by the seller without your consent.
You may be sued for losses
Beyond the deposit, if the seller has to re-list and re-sell the property and achieves a lower price than your bid, they can pursue you for the difference. This is known as a resale shortfall claim and can result in significant financial liability.
Your lender may withdraw
If you are relying on a mortgage or bridging loan and funds are not drawn down in time, your lender may refuse to proceed. This can leave you without the funds needed to complete, compounding the problem significantly.
What if I didn’t instruct a solicitor before the auction?
Ideally, every buyer should instruct a specialist auction conveyancing solicitor before bidding — even before viewing properties. This allows the legal pack to be reviewed in advance, finance to be arranged, and the solicitor to be ready to act the moment you win.
If you did not do this and have just won a property without a solicitor in place, do not panic — but do act immediately. Contact an auction specialist as soon as possible and explain that you have just won a property and have a completion deadline approaching. A good auction solicitor will be able to take on your matter urgently.
You can learn more about preparing correctly in the guide to buying property at auction before you bid, which explains why legal preparation before auction day is so important.
Even if you are starting late, acting quickly after winning gives your solicitor the best possible chance of meeting the auction completion deadline. Every hour counts.

What the special conditions of sale say about timelines
The Special Conditions of Sale are the legally binding contractual terms that govern your auction purchase. They take precedence over the general conditions and will specify the completion date, the interest rate for late completion, and any additional obligations on the buyer.
These conditions are set by the seller before the auction. As a buyer, you are deemed to have read and accepted them the moment the hammer falls, whether or not you actually reviewed them beforehand. This is why reviewing the auction pack before bidding — not after — is strongly recommended.
If you are unsure what to look for in a legal pack, the guide to the auction legal pack explained covers exactly what documents are included and what the key risks are.
Common clauses in the Special Conditions include completion periods of 14 days (rather than the standard 28), elevated daily interest rates, and requirements for the buyer to take over existing tenancies or service charge arrears. Understanding these before you bid can save thousands after the hammer falls.
How 14-day completions work — and why they leave no margin for error
In many auction transactions, the Special Conditions set a completion deadline of just 14 days from auction day. This is a very short window in the context of property conveyancing, which in a standard sale can take 8 to 12 weeks.
In those 14 days, your auction conveyancing solicitor must review all documentation, liaise with the seller’s solicitor, obtain mortgage instructions (if applicable), manage search results, prepare the transfer deed, and ensure cleared funds are in place by midday on completion day.
There is genuinely no time to waste. If you instruct a solicitor on day three or four, you have already lost a significant proportion of your available time. If you instruct on day five or six, meeting the deadline may become impossible.
This is why auction specialists consistently advise that buyers instruct a solicitor after winning at auction on the same day — and ideally have already lined one up before they ever walk through the auction room doors.
Using finance to complete — what your solicitor needs to know
If you are using a mortgage or bridging finance to fund your purchase, your solicitor plays an essential role in managing the communication between you and your lender. Lenders have their own checklist of requirements that must be satisfied before they will release funds, and any delay in providing information can cause funds to arrive late.
Bridging lenders are typically faster than high street mortgage lenders, but they still require valuation reports, legal undertakings, and confirmation of title. Your auction conveyancing solicitor will manage these requirements as part of the conveyancing process.
Regardless of how you are funding the purchase, your solicitor needs to know your finance arrangements immediately upon instruction. This allows them to factor lender timelines into the completion plan.

Why you should instruct before you bid — not after
The most important preparation any auction buyer can make is choosing and briefing their solicitor before auction day. This gives you a significant advantage: your solicitor can review the legal pack in advance, flag any risks, and be ready to issue their invoice and commence work the moment the hammer falls.
Buyers who wait until after winning to find a solicitor face a frantic search under time pressure, often having to explain the property, the timeline, and the special conditions from scratch. This adds unnecessary friction at exactly the wrong moment.
