Legal analysis: According to the effective legal documents, if the jointly and severally liable person repays the debt on behalf of the principal debtor, or if the jointly and severally liable person bears more external liabilities than his share, he may request the people's court that originally tried to exercise the right of recourse. The people's court of first instance shall order the principal debtor or other jointly and severally liable persons to repay. The ruling does not allow appeal, but it can be reconsidered once. If the share of each joint and several liable persons is not determined in the effective legal documents, and the joint and several liable persons exercise the right of recourse against other joint and several liable persons after paying off their debts, they shall file a separate lawsuit with the people's court.

Legal basis: Article 21 of the Civil Procedure Law of People's Republic of China (PRC) is under the jurisdiction of the people's court of the defendant's domicile; If the defendant's domicile is inconsistent with his habitual residence, it shall be under the jurisdiction of the people's court of habitual residence. A civil lawsuit brought against a legal person or other organization shall be under the jurisdiction of the people's court where the defendant is domiciled. Where the domiciles and habitual residences of several defendants in the same lawsuit are under the jurisdiction of two or more people's courts, they shall be under the jurisdiction of each people's court.
