Devolution of joint rights allocates claim to performance to surviving co-obligees and representatives upon death. Devolution of joint rights provides that when a promise is made to two or more persons jointly, the right to claim performance rests with them during their joint lives; after the death of any joint promisee the deceased's representative holds the right jointly with the survivor or survivors; after the last survivor's death the representatives of all hold the right jointly, unless the contract indicates a contrary intention.
