Vagueness

In one sentence

Unclear or imprecise language in a contract that makes the parties' obligations uncertain or ambiguous.

Plain English

Vagueness in a contract means the language is so fuzzy or unclear that it's hard to know what the parties actually promised to do. If a contract says you'll deliver "a reasonable amount" of goods or pay "a fair price," those terms are vague because reasonable and fair mean different things to different people. Courts generally don't like vague contracts because they can't figure out what to enforce, so a vague contract might be declared unenforceable.

Example

A freelance writer agrees to provide "regular content updates" for a website for $500 per month. The contract doesn't specify how many posts, how long they should be, or what topics. This vagueness about the writer's obligations makes the contract hard to enforce.

Used in a sentence

“The contract's vagueness regarding delivery dates and quality standards made it unenforceable.”
