Property boundaries questions and answers
Read answers to frequently asked questions about property boundaries.
Do your maps show legal boundaries?
No. Maps purchased or sourced direct from us never show legal property boundaries, nor do they show ownership of physical features. OS’s commitment is to survey and map physical features on the ground at the time of a land survey, not to define a legal boundary. Therefore, it is not possible to be sure of the position of a legal property boundary from our map.
How can I find out more about property boundaries?
If you are trying to find out who owns an area of land or where a legal property boundary is, please contact HM Land Registry. OS are not able to provide property boundary maps.
Why don't Ordnance Survey maps record legal boundaries?
OS maps are topographic maps, they only show the physical features on the ground at the time of survey. Our maps never show legal property boundaries, nor do they show ownership of physical features. Although some property boundaries may be coincident with surveyed map features, such as a hedge or fence, no assumptions should be made. It is not possible to be sure of the position of a legal property boundary from an OS map.
Therefore, should you have any questions about legal boundaries or responsibility for a wall, fence or hedge, please contact HM Land Registry.
My title plan mentions Ordnance Survey in the acknowledgment. What does this mean?
HM Land Registry creates the title plan from our base mapping. HM Land Registry receives copies of our mapping and can add additional information to their own versions or extra annotation to explain the extent of a legal property boundary. This additional information is not added to our mapping database, so if you have questions about what is shown on your title deeds, in particular the depiction of the red box, please contact HM Land Registry in the first instance.
Your mapping of my property is incorrect. Can I arrange for a surveyor to come out and amend the map?
We welcome all customer feedback about the content and accuracy of our maps. We understand that sometimes there may be a delay between changes taking place on the ground and the time when we are able to capture them. We have a continuous map revision programme, and issues with the content or accuracy of our mapping that fall within our specification will normally be investigated at the next revision of the mapping for the area. Contact us to report a mapping error.
Can Ordnance Survey be my expert witness?
We are unable to become involved in boundary disputes. If you need an expert to prepare evidence, the Royal Institution of Chartered Surveyors offers a dispute resolution service that includes an expert witness.
