Is a plaintiff entitled to attorney fees in a contract?

as attorney[] fees are specifically provided for by statute, the measure and mode of compensation of attorneys and counselors at law is left to the agreement, express or implied, of the parties; but parties to actions or proceedings are entitled to their costs, as hereinafter provided." "There is nothing in the statute that limits its application to contract actions alone. It is quite clear from the case law interpreting Code of Civil Procedure section 1021 that parties may validly agree that the prevailing party will be awarded attorney fees incurred in any litigation between themselves, whether such litigation sounds in tort or in contract.
