Your Legal Obligation

As part of the conveyancing process, you are legally required to answer questions about your property and disclose any known issues. If you knowingly withhold information that would affect a buyer's decision to purchase, they may be able to make a claim against you further down the line if a problem arises.

Being transparent upfront is not just a legal obligation — it's the right thing to do, and it keeps your sale progressing smoothly. Surprises discovered during surveys or conveyancing are one of the leading causes of sales falling through.

What to Disclose

Issues That Must Be Disclosed

The following are the most common categories of known issues that sellers are required to declare during the conveyancing process.

Flooding

Whether the property has ever been flooded and the cause of any flooding.

Disputes

Any disputes relating to the property, including boundaries and borders.

Nearby Development

Any proposals you're aware of for developing property nearby.

Building Works

Any building works undertaken at the property and whether appropriate certificates were obtained.

Insurance Issues

Any unusual or non-standard terms on your insurance, including recent claims.

Japanese Knotweed

Any presence of Japanese knotweed, an invasive plant that can affect structure and value.

Rights of Access

Any rights of access for others to cross your land (e.g. shared footpaths or driveways).

Shared Services

Whether any pipes or services cross another property — or vice versa.

Shared Maintenance Costs

Any shared maintenance obligations, such as a shared driveway or communal areas.

Subsidence

Any history of subsidence or structural movement affecting the property.

Our Advice

How to Handle Known Issues

Having a known issue doesn't necessarily mean your property won't sell — or that you'll get less for it. Many issues are manageable with the right documentation, professional reports, and honest communication with prospective buyers.

Our advice is always to get ahead of it. Talk to us before you list. We can help you understand what to disclose, how to present it, and how to price accordingly. Transparency builds trust with buyers and keeps sales from falling through.

Be upfront early — it avoids delays and protects you from future claims.
Gather any relevant documents: completion certificates, planning permissions, insurance records.
If you're unsure what counts as a 'known issue', speak to your solicitor or us before listing.
Don't assume a buyer won't find out — surveyors and conveyancers are thorough.
Some issues, like Japanese knotweed, are manageable with the right documentation and treatment plan.
