Fixing a Typo After a Document Is Already Signed
A fully executed document with a wrong date, a misspelled name, or two transposed digits is a routine problem, not an emergency. The right fix depends on one question: does the error change what the parties agreed to? Answer that first, then pick the correction path.
Start by leaving the signed file alone. A signed PDF is a fixed record, and an Adobe community answer to this exact question says the same thing: once a document is signed, it cannot be changed. Editing the file after the fact is the worst option available, because it severs the link between what was signed and what now exists. Every legitimate correction is a new, separate record that points back to the original.
Next, sort the error into one of two buckets. The sorting decides everything else.
- Clerical: the intent is unambiguous from the rest of the document. A misspelled name where the email, phone, and business name still identify the same person. A weekday that disagrees with an otherwise correct date. A typo in a descriptive word when the serial number is right.
- Material: the error touches value or identity. Price, quantity, serial or reference number, the legal name of a party or entity, payment or hold dates, jurisdiction. Also any case with more than one error, or where the two sides remember the deal differently.
The rule of thumb: a single clerical error gets a correction sheet; a material error gets a void and re-send; if you are unsure which bucket applies, treat it as material. How a correction is treated legally varies by jurisdiction and by the contract itself, so for high-value pieces ask counsel before choosing the lighter path.
Path A: void and re-send. This is the clean option because the corrected document stands alone.
- Mark the original as superseded. Do not delete it.
- Draft the replacement with every unchanged term copied exactly, and only the error fixed.
- Cite the original's reference number in the replacement, with one line stating that it replaces the earlier version.
- Treat the replacement as binding only once both parties have signed it.
- Update anything built on the old figures: invoices, shipping details, hold dates.
Path B: correction sheet. This is a short document, one page, that amends the original without replacing it. It should contain:
- The original's reference number and signing date.
- The exact original text, quoted, and the exact corrected text, one error per line.
- A sentence stating that all other terms are unchanged.
- Signature lines for both parties. A correction only one side has signed is a claim, not an agreement.
On paper, the habit is a single line through the error with initials beside it. A signed PDF has no margin to initial, so a dated, signed correction sheet does the same job.
Whichever path you choose, the record should let a stranger reconstruct the sequence without asking you. The audit trail should show:
- The original document, unaltered, with its original timestamps.
- A marker that it was amended or superseded, and by which document.
- Who requested the correction, when, and a one-line reason.
- The correction's own sequence of events, each step timestamped.
- Both parties' signatures on the correction.
In lockd, every action (drafted, sent, signed, finalized) is timestamped with IP, and the signed PDF sits with both parties. That means the original stays in the counterparty's hands too. Your correction must therefore say plainly which document governs.
The other side has already signed once and considers the matter closed. A second link arriving unexplained looks like a mistake or a phishing attempt. Send a short message with the link, in the same channel as the original, covering:
- The original's reference number, in the first line.
- The single change, in one sentence: line 3 reads 14 March and should read 12 March.
- What has not changed.
- What you need from them and by when: sign the new version by Friday.
- Which version governs, and that the earlier file is superseded but should be kept.
Most of these corrections are avoidable at the draft stage. Fast signing is the point of the tool, handshake to signed in 90 seconds, so build in a ten-second read-back: say the item, price, names, and dates aloud to the other party before the link goes out. Keep a copy of the draft you sent. Also check how your own signing tool handles superseded documents before you need it, not after.
The decision in short: leave the signed file untouched; classify the error; use a signed correction sheet for one clear clerical slip; void and re-send for anything material or uncertain; and tell the signer what changed before they open the second link.
