mutatis mutandis

Latin term meaning things being changed which are to be changed. This phrase and the use of it may best be explained by an example. A proprietor of an estate fues his lands, and the feu contracts all contain the same general clauses, the same obligations on the feuars and confer the same rights. In such a case two of the feu charters are said to be the same mutatis mutandis, that is, they are the same, if (or when) the name of the disponee, the particular description of the lands feued, and other such-like particulars which are peculiar to each, are changed.
