A joint obligation for creditors is an obligation between not less than two creditors with subject matter divisible in such a manner that each creditor is owed the obligation to the extent of its share; and a joint obligation for debtors is an obligation between not less than two debtors with subject matter divisible in such a manner that each debtor owes the obligation to the extent of its share.

债权人为二人以上，标的可分，按照份额各自享有债权的，为按份债权；债务人为二人以上，标的可分，按照份额各自负担债务的，为按份债务。

If the shares of joint creditors or joint debtors are difficult to determine, the shares shall be treated as being equal.

按份债权人或者按份债务人的份额难以确定的，视为份额相同。
