what is the origin of the name of trover..?
Common-law action to recover the value of personal property that has been wrongfully disposed of by another person.
Late 16th century from an Anglo-Norman French noun use of Old French trover ‘to find’.
A lot of legal terms are of French origin due to that being the principal language used by the Crown and nobility following the arrival of William the Conqueror in 1066. And before that, the Romans and Vikings also put their stamp on the lexicon.
