The statute of frauds is the general name for each state’s statute (law) that requires certain contracts to be in writing—or to have a written memorandum that records the essential elements of the agreement—in order to be enforceable. Statutes of fraud are an exception to the general rule that verbal or oral contracts are just as enforceable as written contracts. Statutes of fraud are designed to prevent fraud and perjury (lying under oath) in transactions that are especially susceptible to fraud.

Statutes of fraud vary from state to state, but generally include (1) contracts for the sale or lease of real estate (land); (2) contracts that cannot be performed within one year from the date of the contract’s formation—such as a two-year employment contract; (3) loan agreements in excess of a certain amount; (4) contracts involving engagement promises (return of engagement rings), marriage (prenuptial agreements), or cohabitation (support, responsibilities) and post-cohabitation support (palimony); (5) contracts for the sale of goods above a certain amount (often $500); (6) promises to pay an estate’s debt from the personal funds of the executor; and (7) contracts in which one person agrees to pay the debt of another person.

In Michigan, the statute of frauds is codified under Michigan Compiled Laws (MCL) and requires certain types of contracts to be in writing to be enforceable. These include contracts for the sale or transfer of an interest in land (MCL 566.106), contracts that cannot be performed within one year (MCL 566.132), and contracts for the sale of goods priced at $1,000 or more (MCL 440.2201, under the Uniform Commercial Code). Additionally, Michigan law requires a written agreement for loan commitments or financial accommodations of $100,000 or more (MCL 566.132a), and for promises to pay someone else's debt, also known as a suretyship provision (MCL 566.132). Prenuptial agreements in Michigan must also be in writing and signed by both parties to be enforceable (MCL 557.28). These requirements are designed to prevent fraud and perjury by ensuring that there is clear and tangible evidence of the agreement's terms and the parties' intentions.
