Sec 835

Supposing there be no agreement limiting their contributions, each joint debtor, who pays more than his share of the indebtedness, may call upon the others to contribute their proportionate shares.1 Such payment, however, to entitle the party making it to recover from his co-debtors, must not be merely voluntary;2 though it is not necessary, if the party paying was bound to pay, that he should have waited till judgment was entered against him.3
