Capacity

Definition

Capacity means you're legally able to enter into a contract. Minors (under 18 in most states), people who are severely intoxicated, and individuals with certain mental incapacities don't have capacity. A contract signed without capacity can be voided.

In Practice

If you're contracting with a sole proprietor, you're relying on that individual's capacity. If you're contracting with a company, the question shifts: does the person signing actually have authority to bind the company? A mid-level manager signing a $500,000 contract they weren't authorized to approve creates a capacity problem for the company — and a headache for you if the deal falls apart.

Frequently asked questions about capacity

Technically yes, but the minor can void it at any time before turning 18 (and for a reasonable period after). The other party can't void it — only the minor can. Contracts for necessities like food, shelter, and medical care are the main exception. This is why smart businesses won't contract with minors without a parent's co-signature.
