(law), in a will, the naming of a second heir, called a substitute heir. In Soviet law—for example, in Article 536 of the Civil Code of the RSFSR—a substitute heir can accede to an inheritance only if the first heir dies before the opening of the inheritance or does not accept the inheritance. In several other socialist countries, such as Hungary and Poland, legislation provides for substitution. In Poland, the law of inheritance allows substitution not only with respect to an heir ex testamento but also with respect to an heir ab intestato (art. 963 of the Civil Code).
