Is a T-mark, together with the back fence, any evidence on a legal boundary the mark on a plan still needs a solicitor, or only a note of what was visible?
A T-mark, together with the back fence, is only a note of a mark on a plan and of a fence that was visible. It is not evidence that settles a legal boundary. The mark on a plan still needs a solicitor. The survey saw the fence: its line, its condition, perhaps who seems to have maintained it. It has not decided the legal boundary, and it has not turned a printed T into ownership. Title is a documents question. The inspection recorded what it could see.

What is the fuller explanation?
On some title plans a T is a convention about who maintains a boundary feature. It is not, by itself, a measured legal line, and it is not always present or decisive. The fence is the physical thing in the garden. Fences get renewed, moved and shared. What you see can differ from the parcels on the title. The survey can say the fence is there and how it looks. Reading the plan against the transfer is the solicitor's work. A photograph of boards does not close that reading.
Send the plan, and the survey note of the fence, to the solicitor and ask them to explain the boundary from the documents. Do not ask the surveyor to award the fence to one owner. If a neighbour dispute is already live, tell the solicitor. The report has not judged it. Keep maintenance of a rickety fence, which is condition, separate from the legal line, which the T-mark has not settled.
What should you ask your surveyor?
- Is a T-mark actually printed on the title plan you hold?
- What did the survey record about the fence itself?
- Has the solicitor read the plan against the transfer?
What are the typical next steps?
- Treat the T-mark as a plan mark, not a verdict.
- Ask the solicitor to read the boundary from the title.
- Keep the fence's condition separate from the legal line.

Also asked about this
Does the survey decide who owns the fence?
No. The survey noted the fence that was visible. Ownership and the legal boundary come from the title, which a solicitor reads. A T-mark, even where the plan shows one, still needs that reading. The inspection has not awarded the fence to either side.
Where should the title plan be read?
With the solicitor, against the deeds and the plan, not in the survey. The survey can confirm what fence was standing. It cannot replace the document. Ask the solicitor to say what the plan shows and what it does not prove about the back boundary.
