10 Common conveyancing mistakes and how to avoid them

When you buy or sell a property, the conveyancing process is vital in ensuring that ownership transfers legally and cleanly. However, many buyers and sellers fall victim to conveyancing mistakes and conveyancing errors that cause delays, extra costs, or even failed transactions. Below, we explore ten common pitfalls—and how you can avoid them.

1. Engaging the wrong conveyancer (or none early enough)

Mistake: Waiting too long to appoint a solicitor or choosing one without relevant property experience.

Why it matters: Delays in legal checks, poor communication, or surprises later on.

Avoidance tip: Start researching and appointing your conveyancing solicitor as soon as you have an offer accepted. Look for credentials such as the Conveyancing Quality Scheme (CQS) and read their client reviews. At ONP Solicitors, we offer a clear, fixed-fee conveyancing service with transparency. 

2. Incomplete or incorrect identification / source-of-funds documents

Mistake: Failing to provide acceptable ID, proof of address, or evidence of where your funds originate.
Why it matters: Anti-money laundering rules require strict compliance; missing documents can stall progress.
Avoidance tip: Prepare in advance: provide passport / driving licence + recent utility bills, and be ready to show bank statements or financial proofs. ONP’s FAQs outline acceptable ID, source of funds, and the use of Armalytix for faster verification. 

3. Underestimating disbursements & additional costs

Mistake: Focusing only on the solicitor’s legal fee and ignoring disbursements (searches, registration, Land Registry, etc.).

Why it matters: Your budget may fall short mid-process, or you may be surprised at the last minute.
Avoidance tip: Ask for a full breakdown up front. ONP publishes sample conveyancing costs which include likely disbursements, and gives you transparency about typical extra costs. 

4. Failing to conduct thorough searches or enquiries

Mistake: Skipping or inadequately reviewing local authority searches, drainage and environmental reports, rights of way, or boundary issues.

Why it matters: Hidden defects (flood risk, planning restrictions, subsidence, party wall issues) can become costly legal headaches.

Avoidance tip: Instruct your solicitor to raise all relevant searches and scrutinise their results. Ask specific questions (through the solicitor) to the seller’s side about recent works, permitted developments, or boundary changes.

5. Relying on verbal promises / incomplete disclosures

Mistake: Trusting verbal assurances from sellers or agents that aren’t included in writing or in the contract.

Why it matters: Verbal promises may not be binding; undisclosed defects may lead to legal disputes.

Avoidance tip: Insist that everything material be documented in the contract pack or in formal replies to enquiries. Make full use of the seller’s property information form and require the seller to list any known issues.

6. Incorrect or missing insurance & title protections

Mistake: Overlooking title insurance, indemnity policies, or missing defects in title that are not registered.

Why it matters: Problems with title or unregistered rights (easements, covenants) can limit your enjoyment of property or reduce its resale value.

Avoidance tip: Where defects or risks are identified, ask your solicitor about indemnity policies. Also, ensure your building insurance is in place from the exchange. ONP’s “Important Information to Consider When Buying a Property” highlights checking insurance costs before completion.

7. Delays in mortgage or financial coordination

Mistake: Not aligning legal deadlines with mortgage lender timelines or failing to deal with lender conditions promptly.

Why it matters: If funds aren’t released when needed, completion may be delayed, and penalties or additional interest could arise.

 Avoidance tip: Keep your mortgage advisor and solicitor in close communication. Give them all documentation early (income, deposit receipts, credit checks). Ensure your solicitor reviews and clears any lender conditions as soon as possible.

8. Poor communication and lack of follow-up

Mistake: Letting your file stagnate, missing reminders, or not responding to solicitors’ requests quickly.

Why it matters: Even small delays in sending paperwork or signing documents can push back completion.

Avoidance tip: Treat your solicitor as a partner: respond promptly, ask for status updates, and use their case-tracker tools. ONP Solicitors emphasise transparency and client communication via their app and case tracker. 

9. Contractual errors / missing schedules & conditions

Mistake: Overlooking special conditions, schedules, fixtures & fittings lists, leasehold terms, or service charge details.

Why it matters: Misunderstandings over what stays or goes, or unclear lease obligations, can cause disputes or unexpected liabilities.

Avoidance tip: Let your solicitor carefully scrutinise and negotiate contract terms. Ask for clarification about what is and isn’t included (furnishings, outbuildings, shared areas). In leasehold cases, check ground rent, service charges, and building insurer details.

10. Rushing to exchange / completion without full checks

Mistake: Exchanging contracts or completing before all enquiries, searches, or checks have been resolved.

Why it matters: Once contracts are exchanged, you are legally bound—even if new issues surface.

Avoidance tip: Never agree to exchange until you and your solicitor are satisfied that all legal issues are addressed. Hold a buffer for last-minute problems. Use completion dates that give a cushion for settlement of funds, registration, or snag issues.
