From the contract page, click + Amendment next to a revision.

The amendment is idempotent: clicking multiple times returns the same file (no new version created). This ensures that the amendment attached to your email always corresponds to the same document.

ILC legal note

⚠️ For commercial leases indexed on ILC, the rent variation cannot exceed the previous year's ILC variation (art. L. 145-34 of the French Commercial Code, as amended by law no. 2022-1158 of 16 August 2022).

IndexFacile calculates the amount and displays a warning if this cap is reached, but it is your responsibility to validate the final amount with your notary or legal advisor before notifying your tenant.
