When a property owner needs to clarify a boundary, one of the first questions is what type of Land Registry plan or boundary documentation they need. Depending on the circumstances, they may need a Land Registry compliant plan, a boundary agreement or a determined boundary application.
Although these terms are sometimes used interchangeably, they describe different processes with different purposes. A plan for Land Registry may support a property transaction, while a boundary agreement records a position that neighbouring owners have accepted. An owner can use a determined boundary application when they want Land Registry to record the exact legal boundary.
Property owners are often unsure about the differences between these options. Choosing the wrong approach can result in unnecessary costs, delays or a plan that does not achieve what the situation requires. For property owners and professionals, understanding the distinction at an early stage can help them choose the correct legal process and plans.
What Is a Land Registry Compliant Plan?
A Land Registry compliant plan clearly identifies land being registered, transferred or leased. An owner may need one for a transfer of part, a new lease, first registration or another application affecting the extent of a title.
The plan must allow Land Registry to identify the relevant land on the Ordnance Survey map. However, most registered title plans operate under the general boundaries rule. This means that the red line shows the general position of the boundary rather than its exact location on the ground.
A compliant plan can show the land in sufficient detail to support a transaction, but it does not automatically determine the precise legal boundary or resolve a dispute between neighbours.
What Is a Boundary Agreement?
A boundary agreement records a boundary position that adjoining property owners have accepted. It may be appropriate where both owners agree where the boundary lies but want to document that position clearly for future reference.
For example, the owners may agree that the boundary follows a particular wall or fence, or that it runs between measured points. A professionally prepared plan can record the agreed position using dimensions and identifiable site features.
The plan must be clear and consistent with the written agreement. A solicitor can advise on the wording, legal effect and whether the owners should note the agreement against the registered titles. When undertaken correctly, a boundary agreement can be binding on subsequent property owners, even where not formalised by a solicitor or submitted to Land Registry.
What Is a Determined Boundary?
An owner can use a determined boundary when they want Land Registry to record the exact position of a legal boundary. It provides more detail than the general boundary shown on an ordinary title plan.
An application normally requires a detailed plan that shows the exact boundary position and includes supporting measurements and relevant evidence. That evidence may include historic deeds, conveyance plans, photographs, information about long-standing physical features or a suitably qualified surveyor’s report that includes all of these.
The adjoining owner will be notified and can object to the application. If the parties cannot agree, the matter may be referred to the Tribunal for formal determination, which can make the process significantly more complex and costly.
Both parties can also submit a joint application to Land Registry for determination if they have agreed the determined boundary line. If both owners agree to jointly appoint a chartered surveyor to make a determination, they agree to be bound by the surveyor’s decision. The parties then submit the joint application to Land Registry.
Why Use a Building Surveyor?
The correct approach depends on what the owner needs to achieve. A Land Registry plan may support a transaction, a boundary agreement may record an accepted position, and a determined boundary plan may formally establish the exact legal line.
A building surveyor can inspect the site and prepare measured, CAD-based plans to help ensure that the boundary is:
- Related to identifiable and permanent site features
- Shown clearly and consistently
- Suitable for use alongside the relevant legal documents
If a dispute arises and the owners need a professional opinion or a determination of the boundary, they can present our surveyor’s report to the neighbour to help reach an agreement or use it to support a unilateral boundary determination application.
If you are uncertain which type of plan you require, our building surveyors are happy to help.
