A four-year statute of limitations applies to claims under the quasicontractual theory of unjust enrichment. 42 Pa. Cons. Stat. § 5525(4); Cole v. Lawrence, 701 A.2d 987, 989 (Pa. Super. Ct. 1997). The statute of limitations begins to run on a claim from the time the cause of action accrues. Cole, 701 A.2d at 989 (citing Packer Society Hill Travel Agency, Inc. v. Presbyterian University of Pennsylvania Medical Center, 635 A.2d 649, 652 (Pa. Super. Ct. 1993)). In general, an action based on contract accrues at the time of breach. Id. Where the contract is a continuing one, the statute of limitations runs from the time when the breach occurs or when the contract is in some way terminated. Id. (citing Thorpe v. Schoenbrun, 195 A.2d 870, 872 (Pa. Super. Ct. 1963)).
