Property boundary checks before buying a home in NI

Check the land being sold, not just the fence you can see

Before buying a home in Derry, compare what you were shown with the land and rights your solicitor is checking. Include the garden, side passage, parking, garage and any strip beyond a fence. A viewing helps you spot questions, but it does not settle who owns each feature or who must maintain it.

The Department of Finance explains that Northern Ireland's Land Registry map identifies registered holdings but generally does not guarantee their boundaries. Do not scale a screen image and treat the result as a precise legal line. If the boundary matters to your decision, give the documents and the physical layout to the appropriate advisers.

Prepare one clear plan of your questions

Make a simple annotated sketch for discussion, labelled as your observations rather than an official plan. Mark each uncertain feature and add a photograph taken with permission. Useful entries include a fence that changes direction, a garage reached over another driveway, or a garden area described differently in the particulars.

Write what you want to establish beside each point: ownership, access, maintenance or the extent of the sale. These are different questions. A passage may be available for use without being part of the land you own, so avoid combining everything under a vague request to check the boundary.

Send the same numbered questions to your solicitor and, where relevant, your surveyor. Ask who is responsible for each answer. This makes it easier to see whether a survey observation needs a title enquiry, or a title document needs someone to compare it with the site.

Ask for the documents that explain the arrangement

nidirect says a registered property's folio can show the owner and rights or charges affecting the land. It also explains that an appurtenant right can benefit land, such as a right of way over a neighbour's property. Ask your solicitor which folios, maps and underlying documents are relevant to your proposed purchase.

Do not assume a line on a map explains everything about access. Ask what the actual wording allows, which route it covers and whether any maintenance arrangement applies. Explain how you expect to use the property, especially if you need vehicle access, deliveries or entry for future building repairs.

If the property is not registered, nidirect directs enquiries to the Registry of Deeds rather than treating an empty Land Registry result as proof that no title exists. Let your solicitor choose the appropriate search and evidence. Keep the legal interpretation out of your own viewing notes.

Resolve a mismatch before promising to move anything

Tell your solicitor about a difference between the documents, the particulars and the layout on the ground. Ask whether further survey work, enquiries or a formal agreement is needed. Do not move a fence, make an informal land swap or promise a neighbour a new arrangement to simplify the purchase.

The Department of Finance describes formal procedures for boundary amendments where the necessary parties agree. That is a reason to obtain advice, not a do-it-yourself solution. Ask the solicitor to explain the proposed route, whose involvement is needed and what evidence would show that the matter has been resolved.

Keep statements of intention separate from completed documents. A seller saying that a neighbour will sign something is not the same as your solicitor confirming the position. Put the outstanding step and the person dealing with it on your purchase checklist.

Price the property you can actually buy and use

When comparing homes, be explicit about the garden, parking and access included in each. Do not value this purchase as if an uncertain strip of land or hoped-for access right were already secured. Ask the agent or valuer to explain the assumptions behind their advice rather than applying a made-up boundary-dispute discount.

An online estimate cannot read the title or resolve a disagreement. Use the guide range for initial planning, then return to the price discussion once the relevant land and rights are clear. Retain the final plan, written answers and any maintenance information for the eventual handover.
