The law also keeps time: four years to sue on a written contract; two years on an oral contract (§ 339) under Cal. Code Civ. Proc. § 337. Fraud claims run three years from discovery (Cal. Code Civ. Proc. § 338(d)); unfair competition claims under Bus. & Prof. Code § 17200 run four years (§ 17208). Contractual limitation clauses can shorten these periods.
