Mixed solidarity

Mixed solidarity refers to solidarity among creditors and debtors, where each one of the debtors is liable to render, and each one of the creditors has a right to demand, entire compliance with the obligation. For example, A and B are solidarily liable to C and D, solidary creditors, in the amount of 1,000. A or B can either pay the whole amount or half to C and/or D. C and/or D can collect payment from A or B. If A paid 1,000 to C, A can reimburse to B in the amount of 500 or such amount agreed upon them. Now, C has the obligation to give D his share in the credit.
