noun
recourse; redemption
Legal/financial term referring to the right to seek compensation or recovery from a party other than the immediate debtor, or the act of redeeming a financial instrument. Often used in contexts like bills of exchange, guarantees, or insurance subrogation.
手形の遡求権を行使する。
Exercise the right of recourse on a bill.
保証人が支払った後、主債務者に対して遡求できる。

償還 refers to repayment or redemption of a debt or bond, while 遡求 emphasizes the right to claim compensation from a third party or prior party in a chain of liability.
求償 is a broader term for claiming compensation or indemnity, whereas 遡求 specifically implies going back up a chain of obligations (e.g., endorsers on a bill).
Compound of 遡 (そ, 'go back, trace back') and 求 (きゅう, 'seek, demand'). The term is a legal coinage reflecting the concept of seeking redress from a prior party.
