Deed Acceptance After Closing Dispute
Ethan Evans purchased property from Echo Systems under a contract requiring the seller to repair the roof before closing. At closing Ethan accepted the deed that omitted any repair promise. After discovering leaks he sued for breach of the original contract term. The court held that the contractual promise merged into the deed and discharged the obligation because the error in failing to include the term in the deed left Ethan without a contract claim.
Party Identity Correction Attempt
Evelyn Ellison sued a company she believed was Echo Systems for breach but later learned the proper defendant was Elite Dynamics. She moved to amend the complaint after the limitations period. The court permitted the amendment because Elite Dynamics knew or should have known that the action would have been brought against it but for the error concerning the proper party's identity.

Unconscionable Enforcement After Mistake
Edgar Evers contracted to sell land to Elemental Pharmaceuticals believing the price reflected full market value. The buyer knew the price was far below value due to an error in the appraisal data.

Mistake Negativing Required Mental State
