Measured boundary evidence and CPR Part 35 reports for encroachment, fence-line and adverse possession disputes — for court and the Land Registration tribunal.
Boundary litigation is won and lost on measured evidence — because the Land Registry title plan alone can't decide where the line runs. Our RICS surveyors act as boundary dispute expert witnesses, turning deeds, historical mapping and precise measurement into CPR Part 35 evidence for the county court and the First-tier Tribunal (Land Registration).
Boundary disputes the panel's experts give evidence in
- Fence, wall and hedge line disputes — locating the legal boundary against title plans, conveyance plans, OS mapping history and physical features.
- Encroachment claims — extensions, driveways and structures built over the line, with measured survey evidence of the extent.
- Adverse possession — expert analysis of occupation extent and boundary features over time.
- Determined boundary applications — the precise plans and evidence HM Land Registry requires.
- T-marks, repairing obligations and party fence walls — interpretation where deeds and the Party Wall Act interact.
Why title plans don't settle it — and what does
Registered title plans show general boundaries, typically at 1:1250, where the red line's own width can represent close to a metre on the ground. What decides these cases is reconstruction: the original conveyance and its plan, historical OS editions, aerial photography, physical evidence on site — measured to survey accuracy and presented so a judge can follow the reasoning. That is precisely the expert's job, and why early expert involvement so often produces a boundary agreement instead of a trial. Not ready for litigation? Start with our boundary dispute cost guide — a boundary report short of Part 35 evidence settles most neighbour disagreements.
Instruction and fees
Party-appointed or Single Joint Expert, across England and Wales. Full Part 35 boundary reports start around £5,000; measured boundary reports for pre-action use cost £500–£1,500. A word of honest advice our experts give freely: boundary litigation routinely costs more than the land is worth — strong early evidence exists to avoid trial, and the expert will tell you if a written boundary agreement is the better outcome.
Frequently asked questions
Can the Land Registry title plan prove where my boundary is?
No. Registered title plans show general boundaries only — at 1:1250 scale the red line itself can represent the best part of a metre on the ground. The legal boundary is established from the original conveyance and its plan, historical Ordnance Survey mapping, and physical evidence on site, measured and interpreted by a surveyor. That reconstruction is exactly what boundary expert evidence provides.
How much does a boundary dispute expert witness cost?
A measured boundary report for pre-action use typically costs £500–£1,500 and settles many neighbour disagreements on its own. A full CPR Part 35 report for court or the Land Registration tribunal starts around £5,000. Given that boundary litigation regularly costs more than the disputed land is worth, our experts advise on merits honestly before you commit to proceedings.
Do boundary disputes have to go to court?
Most don't — and shouldn't. Strong measured evidence produced early usually leads to a negotiated boundary agreement, which can be recorded with HM Land Registry. Courts actively expect parties to attempt settlement or mediation first. Expert evidence exists as much to avoid trial as to win one: a clear, independent survey report gives both sides a realistic view of their position.
