When reviewing a property auction legal pack, the standard conditions of sale provide the legal framework that applies to most transactions. But it is the special conditions of sale that determine the specific terms and obligations attached to the lot you are bidding on. Understanding special conditions of sale is one of the most important parts of any auction due diligence review — and one of the most frequently overlooked by buyers who focus solely on title documents and searches. Getting this wrong can mean unexpected costs, delayed completion or contractual obligations you did not price into your bid.
What Are Special Conditions of Sale?
Every property auction is conducted on the basis of standard auction conditions — most commonly the RICS Common Auction Conditions — supplemented by a set of special conditions that are specific to the individual lot. The special conditions form part of the legally binding contract. Once the hammer falls, the buyer is bound by them, regardless of whether they were read or understood before bidding.
Special conditions typically cover matters such as the deposit amount and how it is to be paid, the completion date and any provisions for delayed completion, whether the property is sold with vacant possession or subject to a tenancy, specific items included or excluded from the sale, any costs or contributions the buyer is required to pay (such as a contribution towards the seller’s legal costs), title restrictions, easements or covenants not registered at the Land Registry, planning or building regulations matters the seller wishes to disclose but not warrant, and any amendments to the standard auction conditions that apply to this lot.
Because they are drafted by the seller’s solicitors, special conditions are written to protect the seller’s position. A thorough pre-auction legal pack review must assess each condition on its practical merits for the buyer.
Why Special Conditions of Sale Matter More at Auction
In a private treaty transaction, a buyer’s solicitor can raise enquiries, negotiate amendments to conditions and seek clarification before exchange. At auction, exchange happens the moment the gavel falls. There is no scope to negotiate, seek clarification or withdraw once the lot is sold. The contract is unconditional and immediately binding.
This means that any special condition you have not reviewed and understood before bidding becomes your obligation by default. Buyers who focus only on the guide price, condition of the property and a brief review of the title register routinely miss conditions that impose additional costs, restrict how the property can be used, or alter the completion timeline in ways that affect their funding arrangement.
In practice, many special conditions are routine and do not materially affect the transaction. However, some conditions require pricing into the deal, legal follow-up before bidding, or — in a small number of cases — a decision to walk away from the lot before the auction date.
Common Types of Special Condition to Look For
Whilst special conditions vary by lot, certain categories appear frequently across auction legal packs and are worth examining systematically.
Seller’s legal costs contribution. It is common for auction sellers to require the buyer to contribute towards their conveyancing costs — often in the range of £500 to £1,500 plus VAT. This is not the same as your own legal fees and is a point to confirm before bidding and factor into your total acquisition cost.
Amended deposit terms. The standard auction conditions typically require a 10% deposit on the fall of the hammer. Special conditions sometimes vary this — either reducing the deposit for certain lots or, less commonly, requiring a higher sum. If you are using bridging finance, confirm the deposit amount in the special conditions and ensure your funding can accommodate it.
Completion date variations. Standard auction completion typically occurs 20 business days after exchange. Special conditions may shorten this — sometimes to as few as five or ten business days — or in some cases extend it. A compressed timeline is a matter to confirm your bridging facility can meet before you bid, not after the hammer has fallen.
Tenancy provisions. Where a property is sold subject to a tenancy, the special conditions will typically identify the tenancy and confirm the purchase is subject to the tenant’s occupation. The condition alone will not tell you the full picture — that requires reviewing the tenancy agreement, any rent arrears position and whether a valid section 21 notice has been served — but the special condition defines the baseline obligation.
Title defects and indemnity insurance. Where the seller is aware of a title defect that cannot be resolved before the auction, they may include a special condition requiring the buyer to accept indemnity insurance in lieu of resolution. The condition should identify the defect and confirm an acceptable insurer and terms. Most title indemnity insurance is standard and workable, but the scope of the policy needs to align with the nature of the defect.
Exclusions from the sale. Fixtures, fittings or items of value may be specifically excluded by special condition. If the property has a boiler, kitchen appliances or other equipment you are factoring into your investment case, confirm what is and is not included.
Special Conditions and Your Completion Deadline
Completion timescales are among the most commercially significant aspects of any auction legal pack. If you are purchasing with auction finance, your lender will need time to carry out their own processes before funds can be released. If the special conditions specify a completion date of ten working days, your finance must be capable of meeting that deadline.
Failure to complete on the contractual date is a serious matter. Under standard auction conditions, the seller has the right to rescind the contract, retain the deposit and claim additional damages if the buyer fails to complete. Some lots include special conditions that modify or intensify these default remedies.
Before bidding on any lot where the completion timeline has been shortened, confirm your bridging lender’s standard drawdown timeline, whether an accelerated completion can be accommodated on their current terms, whether the deposit in the special conditions matches what your facility expects to advance, and whether any conditions precedent in your finance require third-party confirmation that may take time to obtain.
Special Conditions That Can Affect Finance and Exit
Certain special conditions have a direct bearing on whether a property is financeable and how straightforward the exit will be.
Use restrictions imposed by special conditions — for example, a condition restricting the property to residential use only, or prohibiting subdivision — can affect permitted development potential and therefore the development value you are pricing in. A condition requiring the buyer not to apply for planning permission without the seller’s consent may also appear, though this is relatively uncommon.
Where a property is sold with an outstanding enforcement notice or planning condition attached, this may be disclosed by special condition. Understanding the disclosed risk and its likely resolution route is essential before bidding.
For leasehold properties, special conditions may disclose a breach of lease, an outstanding service charge demand, or a notice from the freeholder. These are not necessarily deal-breakers, but they are matters to price and plan around rather than discover after completion.
How to Review Special Conditions Before You Bid
A thorough review of the special conditions in an auction legal pack follows a clear process. Read every special condition in full — do not skim. The most commercially significant conditions are not always the longest or most prominently positioned. Identify any condition that amends the standard auction conditions and understand how the standard position has changed. Quantify any additional costs imposed by special condition and add them to your total acquisition cost before establishing your maximum bid. Note any condition that affects the completion date and confirm your funding can accommodate the timeline. Flag any condition that discloses a title defect, tenancy matter, planning issue or dispute and assess the significance proportionately.
Where a condition is ambiguous, seek clarification from the auctioneer or seller’s solicitor before the auction date. Most auction houses provide a facility for pre-auction enquiries, and written confirmation carries evidential weight if the point is later disputed.
Where a legal pack is incomplete and the special conditions have not been published at the time of your review, this is itself a material gap. The special conditions should be available for review before you bid — if they are not, that is a point to flag and address before the auction date.
When Special Conditions Represent a Genuine Concern
The majority of special conditions in auction legal packs are routine. Seller cost contributions, adjusted deposits and tenancy provisions appear regularly and are manageable once identified and priced. They do not, in themselves, make a transaction unworkable.
Conditions that warrant more careful analysis include those that purport to exclude the buyer from bringing certain claims, those that require completion within a timeline that cannot realistically be met with available finance, and those that disclose a matter the seller is unable or unwilling to resolve and is passing the risk entirely to the buyer.
A condition requiring the buyer to accept the property without any warranty as to planning or building regulations compliance, or one that discloses a significant breach of a restrictive covenant without offering indemnity insurance, is a matter to assess against the specific facts of the lot rather than treat as automatically acceptable. In most cases a practical route to proceed exists — but it needs to be identified before the auction, not after.
