How to sell a property at auction: the legal pack your auctioneer needs from day one
If you want to sell a property at auction, the legal pack is the most important thing you need to get right. Without it, your property cannot go to market — and without a complete one, you risk delaying the sale, deterring bidders, or facing complications after the hammer falls. This guide covers exactly what the auction legal pack must contain, who prepares it, and why getting started early makes all the difference.
What is an auction legal pack?
The auction legal pack is a bundle of legal documents that sellers must provide before a property is listed at auction. It gives potential buyers everything they need to assess the property, understand the legal position, and decide whether to bid.
Unlike a traditional open-market sale, where legal due diligence happens after an offer is accepted, auction sales work the other way around. Buyers review the pack before they bid, because the moment the hammer falls, contracts are exchanged and the sale is legally binding. There is no cooling-off period and no opportunity to renegotiate.
This is why the auction legal pack needs to be accurate, complete, and ready well before auction day. Any gaps or errors can raise red flags, reduce bidder confidence, and ultimately affect the price you achieve.
What must the auction legal pack contain?
The core documents required in every auction legal pack are the same regardless of property type. Additional documents may be needed depending on whether the property is leasehold, tenanted, or commercial.
Title register and title plan
Official copies of the title register and title plan from HM Land Registry confirm who owns the property and show its legal boundaries. If the property is not yet registered, a copy of the deeds and an Epitome of Title will be required instead. Your auction solicitor will obtain these on your behalf.
Special conditions and auction contract
The auction contract sets out the terms of the sale, including the completion date and any obligations for the buyer. Special conditions are clauses that override the standard auction terms — they may include additional costs, specific deadlines, or other requirements. Buyers must review these carefully before bidding, as they are legally binding from the moment the hammer falls.
Property Information Form (TA6)
The TA6 form is a Law Society standard form that covers boundaries, disputes, guarantees, planning permissions, and any informal arrangements affecting the property. It is a legal requirement for auction sales and must be completed accurately by the seller. Inaccuracies can lead to claims further down the line, so it is important to answer every question carefully and honestly.
Property searches
Searches are carried out to reveal issues that may not be obvious from the title deeds. A standard pack includes a local authority search, drainage and water search, and an environmental search. Additional searches may be required depending on the location of the property — for example, coal mining searches, flood plain searches, or chancel repair searches. Searches can take time to return, which is one of the key reasons sellers should instruct their auction solicitor as early as possible.
Energy Performance Certificate (EPC)
An up-to-date EPC is a legal requirement for any property being offered for sale. If your existing EPC is expired or unavailable, you will need to commission a new one before the property can be listed. EPCs are valid for ten years, so check the date on any existing certificate early in the process.

Additional documents depending on property type
The documents listed above apply to every auction listing. Some properties also require additional paperwork depending on their tenure, use, or occupancy.
- Leasehold properties must include a Leasehold Information Form (LPE1 or TA7). This covers the length of the lease, ground rent, service charges, and management company details. Buyers of leasehold properties are particularly reliant on this information, as onerous lease terms can significantly affect the value of their purchase.
- Tenanted properties should include a copy of the tenancy agreement — usually an Assured Shorthold Tenancy — along with a current rent statement. If the property is an HMO (house in multiple occupation), the HMO licence must also be provided.
- Fixtures and fittings may be documented using a TA10 form, which clarifies what is and is not included in the sale. This is particularly useful for furnished or partly furnished properties.
- Commercial or mixed-use properties require a Commercial Property Standard Enquiries (CPSE) form, which covers matters specific to business premises such as planning use, business rates, and VAT.
Who prepares the auction legal pack?
The seller is responsible for ensuring the auction legal pack is complete and accurate. In practice, the pack is compiled by the seller’s solicitor or licensed conveyancer, who will obtain official copies of title documents, commission or verify searches, and draft the auction contract and special conditions.
It is strongly advisable to use an auction specialist rather than a high-street solicitor unfamiliar with the auction process. Auction timelines are much tighter than open-market sales, and a solicitor who understands these deadlines will ensure the pack is ready when the auctioneer needs it — not after marketing has already begun.
At AuctionSolicitor, our auction pack drafting service is designed specifically for sellers who want to get to market quickly and confidently. We collate every required document, draft the special conditions, and ensure nothing is missing — so your pack is buyer-ready from the start.
How long does it take to prepare?
In most cases, a legal pack can be ready within one to two weeks. The main factor affecting this timeline is how quickly local authority and drainage searches are returned, which varies by local council. Some areas respond within a few days; others can take longer.
This is why sellers should instruct their solicitor as soon as they decide to sell a property at auction — ideally before even instructing the auctioneer. The standard window between a property being listed and the auction date is typically three to four weeks. If the legal pack is not ready before marketing begins, bidders will not have enough time to review it properly, which can reduce competition and harm the price you achieve.
What happens if the legal pack is incomplete?
An incomplete auction legal pack creates serious problems. Experienced buyers and their solicitors will spot missing documents immediately, and many will simply walk away rather than bid on a property where they cannot fully assess the risk.
If the pack is missing regulated documents such as the TA6 form, it can cast doubt over the title or the seller’s transparency. In some cases, an incomplete pack may mean the property has to be withdrawn and re-listed, causing costly delays. After the hammer falls, any undisclosed issues can lead to disputes, claims, or difficulty completing within the required 28-day timeframe.

Practical tips for sellers preparing the legal pack
Here are the most important steps to take if you are planning to sell a property at auction:
- Instruct your auction solicitor before you instruct your auctioneer. Starting the legal pack early prevents it from becoming the bottleneck that holds up your listing.
- Check your EPC. If it is expired or missing, commission a new one immediately. It cannot be omitted from the pack.
- Locate any relevant paperwork. Planning permissions, building regulations consents, guarantees, and any tenancy agreements should all be gathered and shared with your solicitor as early as possible.
- Be transparent on the TA6. Disclose any disputes, restrictions, or known issues honestly. Concealing problems at auction carries greater legal risk than it does on the open market.
- Confirm your auction type. Whether you are going to a traditional unconditional auction or a conditional (modern method) auction, your solicitor will need to draft the special conditions accordingly.
Where to find official guidance
