Confession of judgment is a legal term that refers to a type of contract (or a clause with such a provision) in which a party agrees to let the other party enter a judgment against him or her.
Judgment and judgement are both nouns and they have a few different definitions. A judgment or judgement can be the formation of an opinion, the mental ability to perceive or discern, or a legal determination from a court of law. For example, The judgment from the referee was that the touchdown stands.
