What is De Bonis Propriis?

Legal Definition
Of his own goods. When an executor or administrator has been guilty of a devastavit, (q. v.) he is responsible for the loss which the estate has sustained, de bonis propriis. He may also subject himself to the payment of a debt of the deceased, de bonis propriis, by his false plea, when sued in a representative as, if he plead plene administravit, and it be found against him, or a release to himself, when false. In this latter case the judgment is de bonis testatoris si, et si non de bonis propriis. 1 Saund. 336 b, n. 10 Bac. Ab. Executor, B 8.
