noun
Legal term for the obligation to prove one's assertion in court.
民事訴訟では、原告に挙証責任がある。
In civil litigation, the plaintiff bears the burden of proof.
Often used interchangeably with 挙証責任, but 立証責任 can emphasize the act of proving a fact, while 挙証責任 is more strictly the legal burden.
Compound of 挙証 (proof, presenting evidence) and 責任 (responsibility). The exact historical derivation is uncertain; the term is a modern legal expression.
