Soto v. State Chemical Sales Co. International, Inc. · filed 2010-03-26

Under Puerto Rico law, one of the requirements for a valid contract is a “cause for the obligation.” P.R. Laws Ann. tit. 31, § 3391.

First, as Plaintiff has emphasized, she received continued employment in exchange for signing the arbitration agreement. The parties have cited conflicting case law regarding whether or not a promise of continued employment constitutes adequate consideration. This dispute is not determinative, however, because Plaintiff also received consideration in the form of her employer’s promise to give up its own legal recourse to litigation.
