Six kinds of contracts fall under the statute of frauds and must be in a signed writing to be enforceable in court: contracts involving an interest in land, contracts that cannot be performed within one year, promises to pay someone else’s debt, promises made in consideration of marriage, sales of goods worth $500 or more, and an executor’s promise to pay estate debts out of personal funds. If an agreement in one of these categories isn’t put in writing, the deal isn’t automatically void, but a court will refuse to enforce it if the other side objects.
Why These Contracts Need a Writing
The statute of frauds exists to stop people from fabricating oral agreements and dragging others into court over deals that never happened. Requiring a signed writing for the most significant kinds of contracts creates a paper trail that protects both sides. Five of the six categories come from the common law, as reflected in the Restatement (Second) of Contracts; the sixth, sales of goods, comes from the Uniform Commercial Code.
An oral contract that should have been written down is not automatically void. It’s voidable. The agreement is real, and either party can choose to honor it. The problem only surfaces when someone tries to enforce it in court and the other side raises the missing writing as a defense. If the parties later put the same agreement in writing, it becomes fully enforceable without any new promises or fresh consideration.
Contracts Involving an Interest in Land
Any agreement that transfers or creates an interest in real property has to be in writing. That reaches sales, mortgages, long-term leases, and easements giving someone the right to use your land.
“Interest in land” is broader than most people assume. A home purchase obviously qualifies, but so does a deal granting a neighbor permanent access across your driveway or giving someone mineral rights beneath your property. Short-term leases of a year or less are generally exempt, though the exact cutoff varies by jurisdiction.
The writing should identify the buyer and seller, describe the property clearly enough to tell it apart from other parcels, and state the price or other essential terms. Many states also recognize a part performance exception for land contracts: if the buyer has paid part of the price, taken possession, or made substantial improvements, a court may enforce the oral agreement anyway. Those actions are strong evidence a real deal existed.
Contracts That Cannot Be Performed Within One Year
A contract has to be in writing if its terms make it impossible to finish within one year of the date it was made. The key word is “impossible.” If there’s any theoretical way the work could wrap up within twelve months, the contract escapes the statute of frauds no matter how unrealistic that quick finish really is.
This produces some odd results. A two-year employment contract running from January 2026 through December 2027 plainly needs to be in writing because the terms lock it past the one-year mark. A contract to build a house with an eighteen-month estimated timeline does not, because a court can reason that construction could theoretically finish in under a year under ideal conditions. Even a lifetime employment contract falls outside the statute, since the employee could die within the first year, making full performance within that window at least possible.
The clock runs from the date the contract is made, not the date performance begins. A deal signed on March 1 that calls for work starting June 1 and ending the following April already exceeds one year from the making of the contract and needs a writing.
Promises to Pay Someone Else’s Debt
If you promise a creditor you’ll cover someone else’s obligation when that person defaults, the promise has to be in writing. This is the suretyship or guaranty provision. A parent who co-signs a child’s car loan or a business owner who personally guarantees a company’s line of credit is making exactly this kind of promise.
The writing requirement applies only to secondary promises, meaning your liability kicks in after the original debtor fails to pay. If you take over the debt entirely and become the primary obligor, the statute of frauds doesn’t apply; the obligation is now your own.
Courts also recognize a main purpose exception. If your real reason for guaranteeing another person’s debt is to benefit yourself financially rather than to help the debtor, the oral promise can be enforced. The classic example is a business owner who guarantees a supplier’s payment to a subcontractor because the owner needs that subcontractor to keep working on the owner’s own project. Self-interest, not charity, keeps the guarantee alive without a writing.
Contracts Made in Consideration of Marriage
Agreements where marriage itself is the bargained-for exchange for another promise have to be in writing. The most common example is a prenuptial agreement, where the parties set out how property or financial obligations will be handled if the marriage ends. One spouse’s promise to transfer a house or business interest to the other, contingent on going through with the wedding, falls squarely here.
A mutual promise to marry does not trigger the statute. Two people who agree to marry each other aren’t using marriage as consideration for some other deal. The statute targets situations where someone promises money, property, or other value in exchange for the other person’s agreement to marry.
Sales of Goods Worth $500 or More
Under the Uniform Commercial Code, a contract for the sale of goods priced at $500 or more needs a writing signed by the party you’re trying to hold to the deal. The writing doesn’t have to capture every term. It just needs to show that a contract for sale was made and state the quantity of goods involved. The contract isn’t enforceable beyond the quantity the writing specifies, so getting that number right matters more than nailing down every other detail.1Legal Information Institute. UCC 2-201 Formal Requirements Statute of Frauds
The $500 threshold still applies everywhere the UCC is in force.
The UCC carves out three situations where an oral contract for goods is enforceable anyway:
- Specially manufactured goods. If the seller has started making custom goods that can’t be resold to anyone else, the oral contract is enforceable once the seller has made a substantial beginning on production before the buyer tries to back out.
- Judicial admission. If the buyer or seller admits under oath in court proceedings that a contract existed, the oral deal is enforceable up to the quantity admitted.
- Goods delivered or paid for. The contract is enforceable for any goods already received and accepted by the buyer, or for which payment has been made and accepted.
Deals Between Merchants
Transactions between merchants get special treatment. If one merchant sends the other a written confirmation of their oral agreement within a reasonable time, and the confirmation would be enforceable against the sender, it also binds the recipient unless that recipient sends a written objection within ten days of receiving it. A supplier who gets a purchase confirmation by email and sits on it for two weeks can’t later claim the deal was unenforceable for lack of a signature.1Legal Information Institute. UCC 2-201 Formal Requirements Statute of Frauds
An Executor’s Promise to Pay Estate Debts Personally
When someone dies, the executor or administrator of the estate pays off the deceased person’s debts using estate funds. That doesn’t require any special writing because the executor is spending the estate’s money. The statute of frauds steps in only when the executor promises a creditor to cover the deceased’s debts out of personal funds. A signed writing protects executors from being held personally liable based on nothing more than someone’s word.
What Counts as a Valid Writing
The statute of frauds doesn’t demand a polished contract drafted by a lawyer. A memo, a letter, an email chain, or even a napkin with the right information on it can satisfy the requirement. The writing has to identify the parties, describe the subject matter, and lay out the essential terms. For a land sale, that means the property and price. For a sale of goods, the quantity is the term that matters most.
Only one signature is required: the signature of the person you’re trying to enforce the contract against. If you’re the one suing, your own signature is irrelevant for statute of frauds purposes. The signature doesn’t have to be formal. Initials, a stamped name, or a typed name at the bottom of an email can all qualify, as long as the person intended it to authenticate the document.
The writing doesn’t have to live in a single document, either. Courts regularly piece together multiple writings, like a series of emails or a letter paired with an invoice, to find all the required terms. What matters is that, taken together, the documents show the essential agreement and bear the right signature.
Electronic Signatures
Federal law makes clear that an electronic signature or record can’t be denied legal effect just because it’s not on paper. The Electronic Signatures in Global and National Commerce Act provides that contracts formed with electronic signatures are as enforceable as those signed in ink, as long as the transaction involves interstate or foreign commerce.2Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity
At the state level, the Uniform Electronic Transactions Act reinforces the same rule. Adopted in some form by nearly every state, it gives electronic records and signatures the same standing as their paper equivalents. One consistent requirement runs through it: all parties have to agree to conduct the transaction electronically, whether explicitly or by their conduct, such as negotiating only by email.
So a contract signed through a platform like DocuSign, confirmed through an email exchange, or even agreed to by text message can satisfy the writing requirement. The signature still has to belong to the party being held to the deal, and the record still has to contain the essential terms.
Exceptions That Can Save an Oral Agreement
Even when a contract clearly falls under the statute of frauds and no writing exists, courts have developed doctrines that can rescue the deal. These exceptions exist because rigid enforcement of the writing rule sometimes produces more injustice than it prevents.
Part Performance
Part performance comes up most often with oral land contracts. If one party has taken significant steps in reliance on the agreement, like paying part of the purchase price, moving onto the property, or making substantial improvements, courts may enforce the oral deal. Those actions are so consistent with an existing contract that letting the other side hide behind the writing rule would be unfair. Full performance by one side of any type of contract can also take it outside the statute, since the writing requirement serves little purpose when one party has already done everything they promised.
Promissory Estoppel
If you relied on someone’s oral promise to your serious financial detriment and there’s no other way to make you whole, a court may enforce the promise despite the missing writing. Promissory estoppel requires showing that the promise was one the other party should have expected you to rely on, that you actually suffered a real and substantial loss because of that reliance, and that enforcing the promise is the only way to avoid injustice. Courts treat this as a safety valve rather than a routine workaround, and the bar is deliberately high.
Judicial Admission
Under the UCC, if the party resisting enforcement admits in testimony, in a pleading, or elsewhere in court proceedings that an oral contract for goods existed, the contract becomes enforceable up to the quantity admitted. A similar principle applies in some non-UCC contexts. Once you’ve conceded under oath that you made the deal, arguing it needed to be in writing rings hollow.1Legal Information Institute. UCC 2-201 Formal Requirements Statute of Frauds
The safest approach is still to get the agreement in writing from the start. These exceptions exist for situations that have already gone wrong, and proving them adds cost, delay, and uncertainty that a signed document would have avoided.
