A legal description is the precise written description of land or real property used to identify it with certainty in contracts, deeds, transfers, leases, charges and court documents. It typically goes beyond a postal address, which is not usually sufficient for registrable dispositions.In England and Wales and Northern Ireland, a legal description commonly refers to a Land Registry title number together with a description of the property, often by reference to a filed plan. In Ireland, it usually refers to a Property Registration Authority folio and map, or, for unregistered land, detailed deed descriptions. In Scotland, property is identified in the Land Register by title number and title plan, replacing (for most practical purposes) the older sasine descriptions.The expression “legal description” is descriptive rather than a defined statutory term, but the underlying requirements for certainty of subject‑matter are grounded in land law and registration legislation in each jurisdiction. Accurate legal descriptions are critical to avoid boundary disputes, ensure validity of conveyancing documents and securities, and support due diligence, planning and development.
