What is a determined boundary, and do you need one?

The Land Registry Title Plan must not be used to try to decide the location of any boundary; that is not their purpose. The Land Registry Title Plans show only General Boundaries as a public record of, in general terms, who owns what.

Land Registry boundaries …. normally

The Land Registry Title Plan must not be used to try to decide the location of any boundary. That is not the purpose of the Title Plan. The Land Registry Title Plan is intended to show only General Boundaries as a public record of, in general terms, who owns what.

‘General Boundaries’ are as described in Section 60 of The Land Registration act 2002 as follows:

  • The boundary of a registered estate as shown for the purposes of the register is a general boundary, unless shown as determined under this section.
  • A general boundary does not determine the exact line of the boundary.

But what about a Land Registry ‘Determined Boundary’?

So, normally, Land Registry boundaries are not definitive regarding the location of the legal boundary and, in fact, must not be used for this purpose.  The exception, however, is a boundary which has been registered with Land Registry as what is known as a ‘Determined Boundary’.

A Determined Boundary is absolutely definitive as to the location of the legal boundary.  An application can unilaterally be made by either party but generally a Determined Boundary is applied for, and created, following the agreement of both parties in order to fix and finalise an agreed boundary location. Probably, generally, an application of this type by just one party is likely to be legally challenged by the other party.

What’s involved to register a Determined Boundary?

The Land Registry’s requirement for a Determined Boundary are described with their Practice Note 40. These requirements include the need for a plan certified by the Surveyor as accurate to a tolerance of not more than 10mm from permanent fixed physical features or permanent ground markers.  This level of accuracy is difficult to achieve with regards to boundary measurements taken from fixed physical features to, for example, a new timber fence, neither of which, in reality, are likely to be constructed to that level of accuracy.  However, regardless of practicalities and real-life relevance for a boundary line, this is the requirement.

Do I need a Determined Boundary?

There is very well respected, expert legal opinion that, in fact, there are limited additional benefits of a Determined Boundary compared with a more straightforward, and less costly, boundary agreement, which can still be registered with Land Registry

So, the answer does seem to be “no”, that probably you don’t need to go the lengths and costs of a Determined Boundary.  It is likely that probably a more standard boundary agreement will suffice to formalise an agreement between neighbours regarding the location of a boundary.

Consider a Single Joint Boundary Surveyor

Consider a Single Joint Boundary Surveyor

Rather than both parties to a boundary dispute appointing their own surveyor, it may be worth considering a single jointly-appointed surveyor. This may be a Single Joint Expert to provide a report for the Court but might otherwise be at an earlier stage in proceedings, where both parties agree to a Single Joint Surveyor and usually also agree to abide by the conclusions of this surveyor.

Legal boundaries … line on a plan or physical features

For the consideration of the intended location of a legal boundary, both plan evidence and physical evidence are generally of relevance and importance, with increasing significance and importance of physical evidence inversely related to the clarity and reliability of the plan evidence.
