Unenforceable
A contract that is valid in its formation but cannot be enforced by a court due to a legal defense, procedural barrier, or public policy reason.
While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.
US Law · For business owners and foundersWhat is a Unenforceable?
An unenforceable contract is one that was formed with all the required elements (offer, acceptance, consideration, capacity, and legal purpose) but which a court will decline to enforce due to a legal defense, procedural barrier, or public policy. Unlike a void contract (which never legally existed), an unenforceable contract technically exists but cannot be judicially enforced.
A void contract has no legal effect from the outset - it is as if it never existed (e.g., a contract for an illegal act). A voidable contract is valid but may be rescinded by one party (e.g., a contract entered under duress). An unenforceable contract was validly formed but cannot be enforced - courts will not compel performance or award expectation damages.
The most common causes include: (1) Statute of Frauds - oral agreements for real estate, contracts lasting over a year, and other specified types must be in writing; (2) Statute of limitations - bringing a claim after the limitations period has expired; (3) Unconscionability - terms are so one-sided that enforcement would be unjust; (4) Illegal consideration or purpose - though this can also render a contract void.
In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.
Key Elements
Statute of Frauds
Contracts for real estate sales, contracts requiring more than one year to perform, guarantees, and other specified categories must be evidenced by a signed writing. Oral agreements in these categories are unenforceable.Statute of Limitations
A claim on a contract must be brought within the statutory limitations period. After that period, the contract claim is time-barred and unenforceable, even if the contract itself was valid.Unconscionability
Contracts with terms so grossly one-sided or oppressive (procedural or substantive unconscionability) that enforcement would shock the conscience of the court.Effect on Performed Obligations
If one party already performed under an unenforceable contract, they may still recover the value of their performance through unjust enrichment or quantum meruit, even though the contract itself cannot be enforced.Real-World Example
Two parties agree orally that one will sell the other a commercial building for $2 million. Both shake hands and the buyer begins due diligence. The seller backs out. The buyer sues for breach of contract.
Under the Statute of Frauds, contracts for the sale of real property must be in writing and signed. The oral agreement, though genuinely made, is unenforceable. The court will not compel the sale or award expectation damages. The buyer's only potential remedy would be restitution for any out-of-pocket expenses reasonably incurred in reliance on the oral agreement.
This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.
Sample Clause Language
Writing Requirement (Modification Clause)Watch Out For
Partial Performance Exception
In real estate contracts, courts may enforce an otherwise unenforceable oral agreement if the buyer has already taken possession and made substantial improvements - the "part performance" exception to the Statute of Frauds.Electronic Signatures Satisfy Writing Requirements
Under ESIGN and most state law, electronic signatures and electronic records satisfy Statute of Frauds writing requirements, so email agreements can be enforceable if properly authenticated.Unenforceability Is Claim-Specific
A contract may be enforceable for some purposes but unenforceable for others - e.g., a provision that violates the Statute of Frauds may be severable, leaving the rest of the contract intact.Don't let unenforceable deadlines catch you off guard
Key dates tied to unenforceables - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.
Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.
How to Use This in Your Favor
Always Formalize Agreements in Writing
Even if an oral agreement is binding in principle, reduce it to writing immediately. Written contracts avoid Statute of Frauds defenses and provide clear evidence of terms.Include Limitation of Actions Clauses
Consider including contractual limitations periods shorter than the statutory default. If shorter periods are reasonable and conspicuous, courts generally enforce them, giving you more predictability.Frequently Asked Questions
If a contract is unenforceable, is any part of it effective?
Generally, no. Courts will not enforce an unenforceable contract. However, equitable remedies (like unjust enrichment) may compensate a party who performed in good faith.
Can an unenforceable contract become enforceable?
Sometimes. An oral contract that is unenforceable under the Statute of Frauds can become enforceable if the parties subsequently sign a written agreement memorializing the oral terms, or if part performance exceptions apply.
Can parties agree that an unenforceable provision is severable?
Yes. A severability clause specifies that if any provision is unenforceable, the remainder of the agreement continues in effect. This prevents unenforceability of one clause from voiding the entire contract.
