Manu propria is a Latin phrase in the ablative case meaning "(signed) with one's own hand". In its abbreviated form (m.p.), it is sometimes used at the end of typewritten or printed documents or official notices right after the name of the person(s) who "signed" the document exactly in those cases when there is no handwritten signature there.
It is also found in several ancient documents in front of or after the writers signation at the end of the document.
Ordinary personal checks frequently include the abbreviation at the end of the signature line.
