Arizona Statute of Frauds: Nine Categories and the $500 Rule

Under the Arizona Statute of Frauds, nine categories of agreements listed in A.R.S. § 44-101 must be in writing and signed before a court will enforce them, and a separate rule in A.R.S. § 47-2201 adds a writing requirement for most sales of goods priced at $500 or more. If your agreement falls into one of these categories and lives only in conversation, the deal may still exist, but you lose the ability to force the other side to honor it in court.

The Nine Categories That Must Be in Writing

A.R.S. § 44-101 lists the agreements Arizona courts will not enforce without a signed writing or memorandum:¹

A promise by an executor or administrator to pay a deceased person’s debts out of the representative’s own pocket.
A guaranty: a promise to pay someone else’s debt or cover their default.
Any agreement made in consideration of marriage, other than a mutual promise to marry.
A sale of goods worth $500 or more, governed in detail by A.R.S. § 47-2201.
An agreement that by its terms cannot be performed within one year of when it was made.
A lease of real property lasting longer than one year, or any sale of real property or an interest in it.
A contract hiring an agent or broker to buy or sell real property or mines for a commission.
An agreement that by its terms will not be completed during the promisor’s lifetime, or a promise to leave property by will.
A promise to lend money, extend credit, or renew or modify a loan exceeding $250,000, unless the loan is primarily for personal or household purposes.

The writing itself doesn’t need to look like a formal contract. A signed memo, a letter, or a combination of documents can satisfy the requirement, provided it identifies the key terms and is signed by the party you’re trying to hold to the deal.

Real Estate Deals and Leases

Under A.R.S. § 44-101(6), any sale of real property or an interest in real property must be in writing and signed by the party being held to the agreement. Leases split at the one-year mark: a lease for one year or less can be oral and still enforceable, but once the term crosses that line, it must be written. Informal rental arrangements that quietly extend past their original timeframe can end up on the wrong side of this rule.

Agents come with their own trap. If someone signs a real estate agreement on your behalf, that agent’s authority must itself be in writing and signed by you. An oral authorization is not enough, even when the underlying contract is properly written. Any agreement to pay a real estate broker or agent a commission for buying or selling property also has to be written.¹

The One-Year Rule

A.R.S. § 44-101(5) requires a writing for any agreement that by its terms cannot be performed within one year of the date it was made. The controlling phrase is “by its terms.” If there is any realistic possibility the contract could be finished within a year, Arizona courts generally will not use this rule to block enforcement of an oral deal.

An oral agreement to work for someone for two years fits squarely inside the rule and needs a writing. An oral agreement to “work until the project is finished” may not, because the project could conceivably wrap up inside a year. The question is whether full performance within a year is possible, not whether it’s likely.¹

Sales of Goods at $500 or More

Arizona’s version of the Uniform Commercial Code, A.R.S. § 47-2201, makes a contract for the sale of goods priced at $500 or more unenforceable unless some writing shows a deal was made and is signed by the party against whom enforcement is sought, or by that party’s authorized agent.²

The writing does not have to spell out every term the parties agreed to, and small errors or omissions won’t automatically kill enforceability. Quantity is where the statute draws a hard line. The contract cannot be enforced beyond the quantity of goods stated in the writing. If your written confirmation says 200 units but you orally agreed to 500, only 200 are enforceable.

Confirmations Between Merchants

Deals between merchants get more flexibility. When two merchants reach an oral agreement and one sends a written confirmation, that confirmation can satisfy the writing requirement against both parties, even though only the sender signed it. The receiving merchant has 10 days to object in writing. If the confirmation would be sufficient against the sender, the recipient had reason to know its contents, and no written objection goes out within that 10-day window, the confirmation binds both sides.²

Three Exceptions for Goods Contracts

Even without any writing, § 47-2201 lets a contract for the sale of goods be enforced in three situations.

The first is specially manufactured goods. If the seller starts producing goods custom-made for a specific buyer that aren’t suitable for resale in the seller’s normal course of business, the oral contract can be enforced. The seller must have made a substantial start on production or a commitment to source materials before learning the buyer wants out.

The second is an admission in legal proceedings. If the party fighting enforcement admits under oath, in a pleading, or in testimony that a contract existed, the writing requirement drops away. Enforcement is capped, though, at the quantity of goods the party actually admits to.

The third is payment or acceptance. If the buyer has already received and accepted the goods, or if payment has been made and accepted, the contract is enforceable to the extent of what was received or paid for. Partial performance produces partial enforceability.²

Part Performance in Oral Real Estate Deals

Outside the UCC, Arizona courts recognize part performance as an equitable exception, most often in oral real estate contracts. If one party has substantially performed and that performance is clearly tied to the oral agreement, a court may enforce the deal without a writing. The performance must be “unequivocally referable” to the contract. Making a down payment, taking possession, and making improvements are the classic actions courts look for.

This exception is not easily won. Actions that could be explained by some other arrangement won’t qualify. The party seeking enforcement has to show that what they did only makes sense in light of the oral agreement. Courts apply the doctrine cautiously, because it directly overrides a statute meant to prevent exactly this kind of dispute.

Electronic Records and Signatures

Arizona adopted the Uniform Electronic Transactions Act, and A.R.S. § 44-7007 gives electronic records and signatures the same legal weight as paper. An electronic record satisfies any law requiring a writing, and an electronic signature satisfies any law requiring a signature.³

Email exchanges, digital signatures, and other electronic records can satisfy the Statute of Frauds so long as the record shows the key terms and can be attributed to the person being held to it. A contract cannot be denied enforceability solely because it was created or signed electronically.

What Happens if There’s No Writing

Failing the Statute of Frauds does not make an agreement void. The contract may still exist between the parties. What the statute does is bar a court from enforcing it. If both sides voluntarily perform under an oral agreement that technically needed a writing, neither can later sue to unwind the deal by pointing to the statute.

The Statute of Frauds is an affirmative defense. The party who wants to use it has to raise it. A court will not apply it on its own, and a defendant who fails to argue the statute applies can find the oral agreement enforced as though the writing requirement never existed.
