Is a contract valid if someone signs the wrong version?

Why can signing the wrong version create problems?

When multiple drafts exist, it may be unclear which terms govern the relationship. Common issues include:

• Different pricing or payment terms.
• Changes to deadlines or deliverables.
• Revised liability or indemnification clauses.
• Different termination rights.
• Added or removed provisions during negotiations.
• Confusion about which draft was intended to be final.

The more significant the differences, the more likely a dispute may arise about what was agreed.

What evidence can help determine which version controls?

If there is disagreement about the correct contract, the parties may look to their communications and conduct for clarification. Helpful evidence may include:

• Emails identifying the final version.
• Document version numbers or revision dates.
• Records of negotiated changes.
• Signed copies exchanged between the parties.
• Performance under a particular version.
• Written confirmations of acceptance.

Clear documentation can help establish whether the parties intended to be bound by a specific version of the agreement.

What to do next…

1. Compare the signed version to the version that was intended to be final.
2. Identify any differences that affect important business terms.
3. Review emails and communications about the contract drafts.
4. Consider preparing a written amendment or corrected agreement if both parties agree on the intended terms.

What to consider in your specific situation

• The number and significance of the changes between versions.
• Whether both parties believed they were signing the same agreement.
• Communications identifying the final draft.
• Actions taken after the contract was signed.
• Whether the disputed terms affect major business obligations.
• Any procedures the parties used for contract approvals and revisions.
