A deed is any document affecting title, that is, proof of ownership, of the land in question. The land may or may not have buildings upon it. Common types of deed include conveyances, mortgages, bonds, grants of easements, wills and administrations.

Conveyances are transfers of land from one party to another, usually for money. Early forms of conveyance include feoffments, surrenders and admissions at manor courts (if the property was copyhold), final concords, common recoveries, bargains and sales and leases and releases.

Feoffment was an early form of conveyance involving a simple transfer of freehold land by deed followed by in a ceremony called livery of seisin.
