Definition: Admittance refers to the act of entering a building or locality with permission to do so. It can also refer to the historical act of giving seisin of a copyhold estate.

Example: When you go to a concert, you need admittance to enter the venue. This means you need a ticket or some other form of permission to enter.

Explanation: The example illustrates the first definition of admittance, which refers to the act of entering a building or locality with permission. In this case, the concert venue is the building, and the ticket is the permission required for admittance.

Example: In the past, copyhold estates were transferred through the act of admittance, which involved giving seisin of the estate in the lord's court.

Explanation: This example illustrates the historical definition of admittance, which refers to the act of giving seisin of a copyhold estate. In the past, copyhold estates were a type of base tenure that required the tenant to provide customary services to the manor. When the estate was transferred, the transaction was recorded on the court rolls, and the transferee was given a copy of the entry to prove their title. This process was known as admittance.
