An arbitration agreement in a contract is severable I.e. it is an independent contract and remains valid (assuming it is valid) even if the primary contract is void or terminated
We know that an arbitration agreement can be enforced even when the underlying contract is deemed to be void. In Largoza v. FKM Real Estate Holdings, Inc. (N.J. App. Div., Sept. 2022), the issue of whether the underlying contract is void ab initio did not preclude enforcement of an arbitration (or of forum selection) clause that is in and of itself valid.
But how do we know that it can be enforced even when the primary contract is expired?
Are there any case precedents in N.J or United States Supreme Court that specifically upheld an arbitration clause beyond the expiration of the primary contract?
