# Version control

Tracking successive drafts of a contract so the authoritative current version is always identifiable.

## Definition

Version control records every revision of a contract during drafting and negotiation, with timestamps, authorship and change history. It prevents disputes over which text is binding, supports an audit trail and is essential where multiple parties exchange redlines before signature.

## Example

> A dispute over a deleted liability cap is settled because version control shows exactly when and by whom the clause was removed.

## Why this is a business risk

Without version control, "which version did we sign?" becomes unanswerable when a dispute arises. Parties negotiate through email with track-changes files named v2, v2-FINAL, v2-FINAL-REVISED, and the signed version is unclear. Discovering after execution that a key clause was removed in an unreviewed draft, or that a manually amended page was never signed, can undermine the entire agreement.

## How to manage it

- Assign version numbers systematically from the first draft so each iteration is uniquely identifiable, not by filename alone.
- Record who made each change and when, either in the document metadata or in a separate log.
- Archive every intermediate version, not just the final signed text, so the negotiation history is reconstructable.
- Lock the signed version immediately after execution so it cannot be altered, and store it separately from working drafts.
- When an amendment is signed, link it explicitly to the version of the contract it amends and retain both.

### How Contracko helps

Contracko maintains a version history for every contract in the repository, so the full amendment trail is retained alongside the signed document. When a new document is uploaded against an existing contract record, the previous version is preserved rather than overwritten, giving a complete, dated record of how the agreement evolved.

## Frequently asked questions

Common questions about this term.

- **Q:** Does version control only matter during drafting?
  **A:** No. It matters throughout the contract lifecycle. Amendments, addenda and change orders create new versions post-execution, and keeping these linked to the original signed text is just as important as tracking pre-signing drafts.

- **Q:** What is the difference between a version and an amendment?
  **A:** A version is any iteration of the document at any stage; an amendment is a formally executed change to a signed agreement. Amendments create new binding versions; pre-signing drafts are internal working versions.

- **Q:** Can version history be used as evidence in a dispute?
  **A:** Yes. A dated version history showing when a clause was added, changed or deleted can support claims about the parties' intention at the time of signing and can clarify which text is the agreed final version.

- **Q:** How long should version history be retained?
  **A:** At least as long as the contract itself and its post-termination retention period, typically five to seven years from expiry. For contracts with long-tail obligations or statutory requirements, retention may need to be longer.

- **Q:** What is the risk of using email to manage contract versions?
  **A:** Email threads create an implicit version history, but it is fragmented, difficult to search and dependent on individual inboxes. When a team member leaves or an inbox is deleted, the version trail is lost, and reconstructing it from scattered attachments is extremely time-consuming.
