Short answer. Yes. Article 1362 of the Civil Code allows the party who was mistaken — while the other party acted fraudulently or inequitably — to ask a court for reformation. The remedy corrects the written instrument to reflect what was actually agreed, when fraud caused the document to misrepresent the true intention.
What the law says
If one party was mistaken and the other acted fraudulently or inequitably in such a way that the instrument does not show their true intention, the former may ask for the reformation of the instrument.

What Article 1362 addresses
Reformation is the remedy that corrects a written contract to match what the parties actually agreed. Most reformation cases involve mutual mistake — both parties are surprised by the wording. Article 1362 deals with a different and more troubling situation: one party made a mistake, and the other exploited it, acting fraudulently or inequitably, so that the final document does not show the real deal. The defrauded party can ask the court to fix the written contract to reflect what they actually agreed — not what the other party fraudulently inserted.
What 'fraudulently or inequitably' means
Fraud in the context of Article 1362 does not require proof of elaborate deception. It covers situations where the other party knew the document did not reflect the agreement and allowed — or caused — the discrepancy anyway, to their advantage. 'Inequitably' is even broader: it includes sharp practice, manipulation, and bad faith conduct that falls short of outright fraud. If the other party slipped different terms into the final draft after negotiation, presented an altered document for signing, or otherwise caused you to sign something that misstated your agreement, Article 1362 applies.
Only the injured party may seek reformation
Unlike mutual-mistake reformation, where either party may ask for correction, Article 1362 restricts the remedy to the injured party — the one who was mistaken while the other acted fraudulently. The wrongdoer cannot invoke reformation to undo an instrument that was itself the product of their own wrong. This asymmetry is deliberate: the remedy protects the victim of the fraud, not the person who caused the problem.
Evidence needed and time limits
To succeed in a reformation case, you need to show what the parties actually agreed and how the written document differs from that agreement. Useful evidence includes pre-signing correspondence, drafts, negotiation notes, witness accounts of discussions, and any other record of what was said before the document was signed. Courts require clear and convincing proof — a vague recollection that 'it was supposed to be different' is not sufficient. Reformation is also subject to a prescriptive period; if you discovered the fraud some time ago, consult a lawyer promptly to ensure the action is still within time.
