expectant right; contingent right
Legal term: a right that depends on a future event or condition, as opposed to a vested right. Used in contexts such as property law, inheritance, and contracts.
An expectant right in inheritance becomes a concrete right upon the death of the decedent.
この契約では、条件が成就するまでは期待権にすぎない。
Under this contract, it is merely a contingent right until the condition is fulfilled.
Compound of 期待 (expectation) and 権 (right). A calque from Western legal terminology, likely from German 'Anwartschaftsrecht' or English 'expectant right'.
