- mutual mistake
- As justifying reformation of an instrument is one common to both or all parties, where each party labors under the same misconception respecting a material fact, the terms of the agreement, or the provision of a written instrument designed to embody such an agreement. RGS, Cardox Recovery, Inc. v. Dorchester Enhanced Recovery Co., Tex.App. 13 Dist., 700 S.W.2d 635, 639.Mutual mistake with regard to contract, justifying reformation, exists where there has been a meetr ing of the minds of the parties and an agreement actually entered into but the agreement in its written form does not express what was really intended by the parties. Sierra Blanca Sales Co., Inc. v. Newco Industries, Inc., App., 84 N.M. 524, 505 P.2d 867, 873+ mutual mistakeMutual mistake is where the parties have a common intention, but it is induced by a common or mutual mistake. "Mutual" as used in the expression mutual mistake of fact expresses a thought of reciprocity and distinguishes it from a mistake which is a common mistake of both parties. There is something of the thought of a common mistake because it must affect both parties. Mistake of fact as ground for relief may be neither "mutual" nor common in the strict sense because it may be wholly the mistake of one of the parties, the other being wholly ignorant both of the fact upon the faith of which the other has mistakenly acted and that the other has acted upon such an understanding of the fact situation.See also unilateral mistake
