A title plan may show the general extent of registered land, but the physical boundary on the ground may have a separate history. Fences, walls, hedges, sheds, use, maintenance and witness evidence may all matter.
The key is to separate the evidence types before drawing conclusions. Historic plans, conveyances, photographs, occupation evidence and correspondence should be indexed and dated.
Clear Position does not provide legal title advice, but it can help structure the material so a solicitor, surveyor or Land Registry reviewer can understand the factual position faster.
