Resolving Property Boundary Disputes
How to handle disputes over property boundaries, including evidence gathering, mediation, and court proceedings.
Overview
Boundary disputes between neighbours can be stressful, expensive, and disproportionately costly. The legal boundary between properties is defined by title deeds and the Land Registry's title plan — though title plans show only 'general boundaries' and are not definitive to the nearest centimetre. Disputes often arise from ambiguous deeds, informal changes over time, or adverse possession. The Property Boundary (Resolution) Bill has been proposed to create a simpler process, but for now, resolution depends on negotiation, mediation, or court proceedings.
Who Can Use This Process
- You are likely eligible to use this guide if your situation involves resolving property boundary disputes.
- You have a genuine legal basis for the matter (contract, tort, statutory right, etc.).
- You have made reasonable attempts to resolve the matter directly with the other party first.
Step-by-Step Process
Gather Documentary Evidence
Obtain Land Registry title plans, original conveyance deeds (which may contain more precise descriptions), historical OS maps, and any agreements between previous owners. Check for 'T' marks on plans indicating boundary ownership.
- Land Registry title plans show general boundaries only — they are not precise to the nearest centimetre
- Pre-registration deeds may contain more precise boundary descriptions
- Request an official copy of the title register and title plan from Land Registry (£3 each)
Commission a Professional Survey
Instruct a chartered surveyor (RICS-accredited) to carry out a measured boundary survey. This provides precise measurements and compares physical features with title plan boundaries. Expert evidence is often crucial in court.
- Choose a surveyor experienced in boundary disputes
- A topographical survey costs £500–£1,500 depending on complexity
- The survey may reveal that physical boundaries don't match legal boundaries
Attempt Negotiation and Mediation
Try to resolve the dispute through direct negotiation or by using a professional mediator. The Royal Institution of Chartered Surveyors (RICS) offers a Neighbour Disputes Service. Courts expect parties to have attempted ADR before litigation.
- Mediation typically costs £300–£600 per party
- A mediated agreement can be made legally binding
- Courts may penalise parties who unreasonably refuse mediation on costs
Apply to the Land Registry or Court
If resolution fails, you can apply to the Land Registry for a determined boundary (if the dispute is about the position of the boundary line) or issue proceedings in the County Court for a declaration and injunction.
- Determined boundary applications are rare and expensive
- County Court proceedings can cost £5,000–£50,000+ in legal fees
- Consider whether the land in dispute is worth the cost of litigation

Important Warnings
Boundary disputes are notoriously expensive relative to the value of the land in dispute. Always consider whether litigation is proportionate.
If a neighbour has used part of your land for 10+ years (registered land) or 12+ years (unregistered land), they may claim adverse possession.
Building on or near a boundary without checking ownership can lead to trespass claims and injunctions requiring demolition.
