Article 308. Parties obligations.
1. One or at the same time several persons may participate in the obligation as each of its parties - a creditor or a debtor. The invalidity of the creditor’s claims to one of the persons participating in the obligation on the debtor’s side, as well as the expiration of the limitation period on the demand to such a person, do not in themselves affect his claims to the rest of these persons. 2. If each of the parties to the contract is obligated in favor of the other party, it is considered to be the debtor of the other party in what is obliged to do in its favor, and at the same time its creditor in that it has the right to demand from it. 3. Obligation does not create obligations for persons not participating in it as parties (for third parties). In cases provided for by law, other legal acts or by agreement of the parties, the obligation may create rights for third parties with respect to one or both parties of the obligation.
