What Can Delay Completion on a Property Purchase at Auction?

Buying a property at auction is often seen as a quick and decisive way to acquire real estate — and for good reason. Once the hammer falls, the winning bidder is legally bound to complete the purchase, usually within 28 days. However, while the process is much faster than private treaty sales, it's not immune to delays.

In this blog post, we’ll explore the most common reasons that can delay completion on a property purchase at auction — and how you can avoid them.

1. Issues with the Legal Pack

Before bidding, buyers should review the legal pack provided by the seller's solicitors. This includes title deeds, searches, leases, planning permissions, and other essential documents.

Delays can occur if:

• The legal pack was incomplete or overlooked.
• There are unresolved title issues (e.g. boundary disputes or restrictive covenants).
• The property is leasehold with a missing or problematic lease.

Tip: Always have a solicitor review the legal pack before the auction.

2. Financing Delays

Although auction properties require immediate exchange of contracts and a deposit (typically 10%), buyers often rely on mortgages, bridging loans, or private finance to complete.

Delays can occur if:

• Mortgage approval is slower than expected.
• Valuation issues arise (e.g. the lender values the property below the purchase price).
• Bridging finance falls through or is delayed due to incomplete paperwork.

Tip: Secure financing in principle and have your lender ready before bidding.

3. Seller-Related Issues

Sometimes the seller is not as ready as they should be, despite the legal commitment created by the auction process.

Delays can occur if:

• The seller doesn’t have full legal authority to sell (e.g. a probate property without a grant of probate).
#
• Outstanding issues arise post-auction, such as tenant disputes or contract breaches.

Tip: Read the special conditions of sale in the legal pack to understand any potential hurdles.

4. Survey or Structural Problems

Although not common post-auction (since surveys should be done beforehand), some buyers may uncover major issues after the purchase is agreed.

Delays can occur if:

• A late survey uncovers major defects (subsidence, asbestos, etc.).
• Insurance becomes difficult to obtain because of the condition.

Tip: If time allows, conduct a survey before the auction — or factor in repair risks when bidding.

5. Title or Land Registry Issues

Even minor discrepancies in the title plan or ownership records can hold up the completion process.

Delays can occur if:

• There are unregistered parcels of land involved.
• The title is defective and needs to be resolved or indemnified.
• Easements or rights of way are unclear.

Tip: Have a solicitor thoroughly check the title before bidding

6. Delays in Conveyancing or Communication

While auction timelines are strict, delays can still come from slow responses or poor communication between solicitors, especially if one party is inexperienced with auction sales.

Delays can occur if:

• Your solicitor or the seller's solicitor is unfamiliar with auction timescales.
• Documents or signatures are delayed, especially if parties are abroad.

Tip: Use a solicitor who is experienced in auction purchases and emphasize the deadline.

7. Special Conditions in the Contract

Auction sales often have special conditions that override standard completion terms.

Delays can occur if:

• A longer or shorter completion period is set out in the contract, and parties misinterpret it.
• Completion is conditional on certain events (e.g. planning approval, third-party consents).

Tip: Always read the special conditions carefully — and clarify anything unclear before bidding.

Final Thoughts

Buying a property at auction can be a great way to secure a deal, but it comes with legal and financial obligations that demand preparation. Many delays in completion are avoidable with due diligence, proper legal advice, and financial readiness.

If you do encounter a delay, be aware that failing to complete on time can result in penalties, loss of deposit, or even legal action. Preparation is your best defence.
