A T mark on the title plan sits on a leaning garden pier. Which document is the mark, and which sentence is the lean?
The T mark is a mark on the title plan. The lean is a sentence in the survey. They are not the same document and not the same kind of statement. A T on a title plan is a conveyancing convention about a boundary feature, read with the register and the deeds. The leaning pier is a condition the surveyor saw in the garden. The survey has not interpreted the legal effect of the T, has not decided who must repair the pier, and has not turned the lean into a title finding. The solicitor reads the mark. The survey describes the lean.

What is the fuller explanation?
Title plans are drawings of the land, with marks that lawyers read against the register. A T is one of those marks. It is not a crack or a measurement of how far a pier leans. The survey can say the pier leans. Putting the T and the lean in one breath is easy because they concern the same pier. They still come from different papers. The mark does not prove the cause of the lean, and the lean does not prove what the T means.
Ask the solicitor to read the T with the title register and to say what it indicates for this pier. Give them the survey sentence separately: the pier leans. Repair does not rewrite the title. The survey has not awarded the cost and has not said a neighbour is liable. Do not say the T mark means the lean has been accepted, or that the lean means the boundary has moved. One is the plan. The other is the condition.
What should you ask your surveyor?
- Is the T a mark on the title plan rather than a finding in your report?
- What did you record about the lean of the pier, as condition only?
- Have you decided who repairs the pier, or left that to the title?
What are the typical next steps?
- Keep the T mark with the solicitor and the title plan.
- Keep the lean as a condition sentence about the pier.
- Do not treat either document as a decision on liability.

Also asked about this
If the T points at the pier, does the lean belong to the neighbour?
The survey has not said so. A T is read by the solicitor with the register and the deeds. The lean is only the condition of the pier. The direction of a mark on a plan does not, in this report, award the repair or name a neighbour as responsible. Those are title questions.
Can the survey confirm the boundary follows the leaning pier?
No. The survey can say the pier leans. Where the legal boundary runs is a title question, and the T mark is part of that paper, not part of the condition sentence. The solicitor matches the plan to the ground. The inspection has not redefined the boundary.
