Intromission

Intromission, in Scotch law, is the assumption of authority to deal with another's property. It is divided into legal and vicious. Legal intromission is where the party is expressly or impliedly authorised, either by judgment or deed, to interfere, as by drawing the rents or getting in debts. Vicious intromission is where an heir or next of kin, without any authority, interferes with a deceased person's estate; as, for example, where a person not named by a will, or without the authority of any will, collects the property of the deceased person as if he were regularly appointed. By so doing the vicious intromitter incurs the responsibility of paying all the debts of the deceased. The vitiosity, however, may be taken off by the intromitter being regularly confirmed executor. The corresponding phrase in England to a vicious intromitter is an executor de son tort.
