Short answer. Yes. The Civil Code allows a court to order an instrument reformed when it fails to express the true intention of the parties because of the ignorance, lack of skill, negligence or bad faith of the person who drafted it, or of the clerk or typist. The deal survives; the document is corrected.
What the law says
When through the ignorance, lack of skill, negligence or bad faith on the part of the person drafting the instrument or of the clerk or typist, the instrument does not express the true intention of the parties, the courts may order that the instrument be reformed.

Reformation corrects the paper, not the bargain
This is the distinction everything turns on. Reformation under Article 1364 of the Civil Code starts from the premise that you and the other side did agree, and agreed on the same thing — the writing simply came out wrong. The remedy rewrites the instrument to match that agreement. It is not a way to escape a deal you now regret, to improve terms you accepted with open eyes, or to add something never discussed. Note the breadth of the causes the article accepts: not just an honest slip but ignorance, lack of skill, negligence or bad faith on the drafter's part, and the drafter can be the lawyer, the notary's staff, or the person who typed it.
What you will actually have to prove
A signed and notarised document carries real weight, so the burden on the party asking for reformation is heavy, and it is a burden of clear evidence of the true intention. Courts look for what existed before and around the signing: the term sheet, the offer and acceptance, the emails and messages exchanged while negotiating, earlier drafts showing the correct figure, the receipts and payments actually made, and how both sides behaved afterwards. Conduct is often the strongest proof of all — if the parties acted for years on the terms you say were agreed, the document reads like the outlier. Bare recollection, unsupported, rarely carries it.
When reformation is not available
The remedy has limits worth knowing before you spend on a case. It presupposes a valid, existing contract; if there was never a real meeting of minds, the problem is not a drafting error and the proper attack is on the contract itself. Where only one party was mistaken and the other honestly relied on the writing as it stands, reformation is not the answer either — the Civil Code deals with that as a defect of consent, with different consequences. Certain instruments are also outside reformation altogether, including simple donations without conditions and wills. And a party who has already brought an action to enforce the instrument as written can be barred from turning around to ask that it be reformed.
Practical steps while the error is fresh
The cheapest fix is not a lawsuit. If the other side agrees the document is wrong — and where the error is obviously clerical they often do — execute a corrected instrument or a deed of confirmation, notarised, and register it where the original was registered. Move quickly, because reformation is an action with a prescriptive period and because third parties who deal with the property in reliance on the document as written complicate matters badly. Meanwhile, preserve everything: the drafts, the transmittal emails, the notary's copy, the proofs of payment. If the other side denies the agreement you thought you had, have the file reviewed before you pay or perform anything further; you can book a consultation with us.
