Legal Definitions - legal memory

Legal memory refers to the period during which a legal right or custom can be determined or established. In common-law, legal memory traditionally began in the year 1189, but in 1540 it became a steadily moving period of 60 years.

For example, if someone wants to claim ownership of a piece of land, they must prove that their ancestor was in possession of the land within the legal memory period. If the legal memory period is 60 years, they must prove that their ancestor was in possession of the land within the last 60 years.

The concept of legal memory is important because it sets a time limit for legal claims. Without a time limit, people could make claims to property or rights that date back centuries, which would be impractical and unfair.
