The intention, the count, and the foundation, ought to be certain, and so ought the thing to be which is brought for judgment.

Explanation

Every element of a legal proceeding must be stated with certainty — vague or indefinite claims deprive the opposing party of fair notice and prevent the court from rendering a proper judgment.

Where this applies

• My complaint was so vague that the other side didn't know what I was claiming.
• The lawsuit must clearly identify what is being disputed — vague claims get dismissed.
