A more thorough explanation:

occupavit

Occupavit is a legal term used in history to describe a writ that was used to regain possession of land or a tenement that was taken away during a time of war.

During a war, if someone was forced to leave their land or home, they could use an occupavit writ to regain possession once the war was over.

For example, if a family was forced to leave their home during a war and someone else moved in, the family could use an occupavit writ to legally regain possession of their home.

These examples illustrate how occupavit was used as a legal tool to help people regain possession of their property after it was taken away during a time of war.
