What do T-marks on a title plan mean?

The mark is a capital T drawn against the boundary line, with the stem pointing into the land of the party who carries the responsibility. Deed wording of the sort Land Registry quotes runs along the lines of maintaining the boundaries marked with an inward facing T mark. The word to watch in Land Registry's own description is or. A T-mark is normally a statement concerning the ownership of a boundary structure or the liability to maintain and repair it, so finding one does not by itself prove you own the fence, only that responsibility sits on that side.

Whether the mark counts at all depends on the deed text. Land Registry is explicit that T-marks on deed plans which are not referred to in the text of a deed have no special force or meaning in law, and unless an applicant specifically asks for them to be shown, Land Registry will normally ignore them. Where the deed does refer to them and sets the wording out, they are reproduced on the title plan and referred to in the register, or the affected boundary is described in words, or a copy of the deed plan is filed with the title.

Most properties have nothing of the kind. The register only shows information about ownership or maintenance of boundary features where the deeds lodged for registration specifically referred to it, and GOV.UK confirms that in England and Wales there is usually no record of who owns the fence between two properties. Order your title register and title plan from Land Registry and read them together. If the register is silent, that silence is the answer, and the boundary is best treated as a party boundary, altered only by agreement with the adjoining owner.

Do not stretch what a T-mark gives you. It says nothing about where the legal boundary runs, because the title plan shows general boundaries and does not fix the exact line. It says nothing about which way the posts should face or which side gets the smooth finish, both of which are convention rather than law. What it does do is settle an argument about who pays, which is usually the argument being had. Bring a copy to the quote and we will set the fence out to match what the deeds actually say.
