Boundary checks before selling a house in Northern Ireland

By James Gorman

Check what you are selling before writing the listing

Before marketing a house in Derry or Londonderry, check that you can explain the extent of the property clearly. The house may be straightforward while a side passage, parking space or strip of garden raises a question. Sorting the paperwork first gives you a better starting point for the agent's appraisal and the buyer's enquiries.

This is a preparation checklist for sellers, not a way to decide a disputed boundary. If the documents and what you see on the ground appear different, ask your solicitor what needs checking before making a statement about ownership. An estate-agent photograph or an online map is not a substitute for that review.

Gather the right plans and keep their dates

Ask your solicitor which title records and plans are relevant to the sale. Put any existing agreements, correspondence and survey drawings in the same folder, with dates and a short note explaining where each came from. Keep an unaltered copy of every document.

The Department of Finance explains that a land certificate reflects registrations at the time it was issued or reissued and can be incomplete. Its registered conveyancing guidance is a useful reason to have the current position checked rather than relying on an old folder from your purchase.

Do not treat the registry line as an exact fence position

Northern Ireland's Department of Finance says the Land Registry map identifies registered holdings but does not guarantee their boundaries. Read its Land Registry map guidance with your solicitor if a line appears inconsistent with a fence, wall or hedge.

For your preparation notes, photograph the area in question and describe the apparent difference neutrally. Do not move a fence, redraw a plan or tell a buyer that a disputed strip is included simply to make the listing easier. Ask whether a professional survey is needed and what question it should answer.

Give gardens, access and parking their own checklist

Walk around the property and note each area you expect the buyer to use: the rear garden, side passage, driveway, garage approach and any separate parking space. For each, write down what you understand and which document supports it. Leave uncertain points marked for review instead of filling the gap with an assumption.

Use the same approach for shared routes. Ask your solicitor to confirm the relevant rights and obligations, and ask the agent how the confirmed position should be described in the particulars. A gate that has always been used is a useful observation to report; by itself it is not your professional confirmation of the legal position.

Flag disagreements and proposed changes early

If there has been a disagreement, give your solicitor the relevant correspondence and a factual timeline. Ask how to answer buyer enquiries accurately and what can be said in the marketing material. Do not rely on a general online checklist to decide what must be disclosed in your particular sale.

The Northern Ireland Department of Finance guidance linked above describes formal processes for boundary corrections and amendments. Let your solicitor advise whether any process applies; this article does not recommend a do-it-yourself agreement or predict how long a resolution will take.

Keep the appraisal tied to the confirmed property

Bring your questions and documents to the appraisal so that the price discussion relates to what is actually being offered. A garden or parking arrangement that has not been confirmed should not quietly become a selling point. Equally, an unresolved question is not evidence for an arbitrary percentage discount.

For the wider paperwork, see our Northern Ireland title-deeds guide. When you are ready, contact James Gorman Property to discuss selling, or start with the Derry guide valuation. The online guide cannot confirm land ownership or resolve a boundary.
