Quantity Term Correction in Supply Deal
Apex Components and Ridge Appliances negotiated a supply agreement for 10,000 motor units per quarter. A formatting glitch in the final document reduced the quantity to 1,000 units, and both parties signed without noticing. When Ridge later sued, the court read the quantity term as 10,000 units and enforced the contract on that basis.
Payment Flow Reversal in Swap Confirmation
Summit Bank and Harbor Fund executed a derivatives confirmation that reversed the intended payment flows due to a copying error from a mirrored draft. Both parties later stipulated they had not intended the reversal. The court construed the confirmation to require the originally agreed payment direction and enforced it accordingly.

Escalation Clause Omission in Lease
Pine Tower LLC and Apex Corp. signed a lease after agreeing in every draft to annual rent increases. Brokers mistakenly circulated an earlier draft that omitted the escalation clause. The court read the lease to include the escalation term the parties had intended and enforced the adjusted rent obligation.
Price Formula Adjustment in Aluminum Contract
Alcoa and Essex entered a long-term aluminum supply contract with a pricing formula both believed would track production costs. Unforeseen electricity cost spikes rendered the formula grossly inaccurate. The court construed the price term to provide Alcoa a reasonable profit consistent with the parties' original expectations and enforced the contract on that basis.

Accounts Dispute in Franchise Litigation
Dairy Queen and Wood disputed amounts owed under a trademark and contract arrangement.

Common questions
Frequently Asked

How does reformation at law differ from traditional equitable reformation?+
Reformation at law allows a court to achieve the same corrective result by simply construing and enforcing the document according to the parties' actual agreement. Traditional equitable reformation requires an in personam order directing physical alteration of the writing. The legal approach avoids equity's personal decree when third-party reliance on the document is not a concern.

When will a court grant reformation at law for a mutual mistake in a writing?+
A court grants reformation at law when both parties intended a particular term, the executed writing fails to express that term because of a shared mistake as to its contents, and no innocent third party would be unfairly prejudiced. The court then reads the intended term into the document and enforces the agreement as corrected.
Supporting sources
Does ordinary negligence by one party in preparing the writing bar reformation at law?+
Ordinary negligence in transcription does not bar reformation at law. The doctrine focuses on whether the writing fails to express the parties' shared agreement due to mutual mistake. Only fault rising to bad faith or violation of reasonable standards of fair dealing prevents relief.
