An allegation contrary to a deed is not admissible.

Explanation

A party may not contradict by oral allegation what he has solemnly committed to a written instrument; the deed speaks and cannot be gainsaid.

Where this applies

• They're making oral claims that contradict what they committed to in writing.
• A party can't use verbal allegations to override their own written instrument.
• You can't gainsay what you solemnly put in a deed by saying something different later.
