Quick answer
Capacity usually means legal ability to enter binding agreements. In contracts, it matters because agreements with incapacitated parties may be voidable. Before signing, verify the other party's authority and mental state.
Definitions
What is capacity?
Legal Definition
Capacity determines whether a person or entity can legally enter into binding agreements or be held liable for their actions. Without proper capacity, contracts can be voidable at the option of the incapacitated party. Minors, mentally incapacitated persons, and corporations with limited authority have restricted capacity depending on jurisdiction.
Plain-English Translation
Like a child needing parental permission to enter into binding contracts, individuals must have legal capacity to be bound by agreements they sign.
Contract relevance
Why capacity matters in contracts

Missing or vague
If capacity is missing or vague
If capacity is undefined, disputes may arise about whether a party can be held to the contract terms, particularly when dealing with minors or mentally impaired individuals.
Vague capacity provisions may lead to litigation about whether a corporate officer had proper authority to bind the entity.
The absence of clear capacity language can create uncertainty about whether a contract is enforceable or voidable, potentially resulting in costly court battles.
Parties may disagree about what capacity was represented at the time of signing, especially when dealing with complex agreements involving multiple entities.

Document context
How capacity shows up in legal documents
Why does it matter?
Ignoring capacity can result in voidable contracts and potential personal liability for the party who should have verified capacity. The party drafting the contract typically bears this risk.
When does it matter?
Capacity becomes an issue when a party to a contract seeks to void the agreement due to incapacity or when enforcing a contract against a party claiming lack of capacity.
Where is it usually seen?
Capacity appears in contract formation documents, court pleadings in contract disputes, guardianship proceedings, and statutes like the Uniform Commercial Code § 1-203.
Who is affected?
Minors lack full capacity to contract, risking voidable agreements. Corporations act through authorized agents whose capacity affects the corporation's binding obligations.
How does it work?
First, determine if a party has legal capacity based on age, mental state, or corporate authorization. Then, assess whether the other party knew or should have known about the incapacity. Finally, evaluate whether the contract can be enforced or voided based on these factors.
