Define: Null and void
Null and void describes a contract or clause that has no legal effect whatsoever, as though it never existed. When a contract is declared null and void, neither party can enforce its terms, and courts treat it as though no valid agreement was ever formed between the parties.

What Null and void Means in a Contract
The phrase null and void signals that a contract, clause, or obligation carries absolutely no legal weight. Unlike a voidable contract, which remains valid until one party successfully challenges it, a null and void agreement is treated as though it never came into existence. This distinction matters because it affects remedies, rights, and the ability of either party to enforce anything under the supposed agreement.
Parties often encounter this phrase when a fundamental legal requirement is missing from the outset. For example, a contract formed for an illegal purpose, signed by a party lacking capacity, or missing an essential element such as consideration may be declared null and void by the law governing the contract. In these cases, no amount of subsequent performance or goodwill can revive the agreement.
Contract drafters use this language deliberately to describe the most severe consequence available, since declaring something null and void wipes out any obligations that might otherwise have arisen. This is stronger than terminating a contract, which typically ends future obligations while preserving accrued rights and liabilities up to the point of termination.
How Null and void Is Defined or Measured
There is no numerical test for whether something is null and void. Instead, the determination rests on whether a foundational legal defect exists at the time the contract was supposedly formed. Common triggers include lack of legal capacity, absence of genuine consent, illegality of purpose, or failure to meet formal requirements such as required signatures or witnessing.
Courts and tribunals typically look backward to the moment of formation rather than forward to performance. If the defect existed from the start, the agreement is void from inception, sometimes described using the Latin phrase void ab initio. This differs from later-arising problems, such as a breach, which do not automatically render a contract null and void but instead trigger remedies like damages or termination.
- Illegality of subject matter or purpose
- Lack of capacity, such as a minor or an entity acting outside its authority
- Absence of genuine agreement, such as fraud vitiating consent entirely
- Failure to satisfy mandatory formalities required by the law governing the contract
Where Null and void Appears in Agreements
This phrase commonly appears in severability clauses, regulatory compliance provisions, and representations and warranties sections. A severability clause might state that if any provision is found null and void, the remainder of the agreement continues in force, protecting the parties from losing the entire deal over one defective term.
The phrase also surfaces in notices and formal correspondence, including a Relevant Circumstances
