A more thorough explanation:

Definition: Finesur concessit is a legal term in Law French. It refers to a type of conveyance where the cognizor grants the cognizee an estate de novo, usually for a term of years or for life, without acknowledging the cognizee's preceding right in land. This is done by way of supposed composition.

Example: John owns a piece of land and wants to sell it to Jane. Instead of acknowledging Jane's right to the land, John uses finesur concessit to grant Jane a new estate in the land. This means that Jane now has a new right to the land, but John does not acknowledge her previous right.

Explanation: Finesur concessit is a way for a person to grant another person an estate in land without acknowledging their previous right to the land. This is done by creating a new estate, which is usually for a term of years or for life. The example shows how John uses finesur concessit to grant Jane a new estate in the land without acknowledging her previous right. This means that Jane now has a new right to the land, but John does not acknowledge her previous right.
