Reformation in legal terminology refers to the correction or change of an existing document by court order upon petition of one of the parties to the document. Reformation will be ordered if there is proof that the parties did not intend the language as written or there was an omission due to mistake or misunderstanding. Quite often a party petitions for reformation when one or both parties realize the effect of the document as written is different from what was expected but it has already been recorded or filed with a governmental agency.
