Where two or more persons are jointly and severally liable in accordance with the law, the obligee is entitled to request assumption of liability by part or all of the persons jointly and severally liable. The shares of liability of persons jointly and severally liable shall be determined based on the gravity of liability of each person; or the liability shall be evenly shared if it is difficult to determine the gravity of liability of each person. If the liability actually assumed by a person jointly and severally liable exceeds the person's share of liability, the person shall be entitled to claim indemnities from other persons jointly and severally liable. The joint and several liability shall be governed by the provisions of laws or the agreements of the parties. ⼆人以上依法承担连带责任的，权利人有权请求部分或者全部连带责任人承担责任。 连带责任人的责任份额根据各⾃责任大小确定；难以确定责任⼤小的，平均承担责任。实际承担责任超过⾃己责任份额的连带责任人，有权向其他连带责任人追偿。 连带责任，由法律规定或者当事人约定。
