DIFFERENCE BETWEEN PASSIVE SOLIDARITY (SOLIDARITY AMONG DEBTORS) AND SURETYSHIP
The two are SIMILAR in the following ways:
1. A solidary debtor, like a surety, STANDS FOR SOME OTHER PERSON.
2. Both debtor and surety, after payment, may require that they be REIMBURSED.
The difference is that the lender cannot go after the surety right away. There has to be default on the part of the principal debtor before the surety becomes liable. If it were mere solidarity among debtors, the creditor can go after any of the solidary debtors on due date.
