A more thorough explanation:

De maritagio amisso per defaltam is a legal term in Latin that refers to a writ that was available to a tenant of a frankmarriage to regain land that was lost due to default.

An example of the use of this writ would be if a tenant of a frankmarriage failed to appear in court to defend their right to the land, and as a result, the land was taken away from them. The tenant could then use the writ of de maritagio amisso per defaltam to regain the land that was lost.

Another example would be if a tenant of a frankmarriage was wrongly dispossessed of their land, they could use this writ to regain their rightful ownership of the land.

These examples illustrate how the writ of de maritagio amisso per defaltam was used to protect the rights of tenants of frankmarriage and to ensure that they were not unfairly deprived of their land.
