# Art. 3037. Surety ostensibly bound as a principal with another; effect of knowledge of the creditor

One who ostensibly binds himself as a principal obligor to satisfy the present or future obligations of another is nonetheless considered a surety if the principal cause of the contract with the creditor is to guarantee performance of such obligations.

A creditor in whose favor a surety and principal obligor are bound together as principal obligors in solido may presume they are equally concerned in the matter until he clearly knows of their true relationship.
