An amendment template, not advice on your situation. Read it with the lease: the landlord and every tenant sign it and keep a copy.
The amendment is written in French, like the lease it amends.

The lease amendment, in practice.
What an amendment can change
An amendment changes the current lease by mutual agreement: Service-Public defines it as the document added to the contract that records a change, an adjustment or an addition agreed by both sides. The landlord and every tenant sign it.
It does not serve to let another home, which takes a new lease, nor to raise the rent outside the cases the law provides for.
The rent
The rent can go down by mutual agreement. During the lease, it only rises through the yearly IRL review, if the lease provides for one, or through an increase for improvement works the landlord has carried out: the lease or an amendment sets that increase (article 17-1 II of the law of 6 July 1989; for a furnished let, article 25-9, which adds equipment bought on top of the initial furnishings).
For an unfurnished let, the increase is forbidden in a home rated F or G, for a lease signed, renewed or tacitly renewed since August 24, 2022 in mainland France, July 1, 2024 in Guadeloupe, Martinique, French Guiana, La Réunion and Mayotte (article 17-1 III). The tool refuses it for a furnished let too.
A co-tenant moves in or out
The new co-tenant signs the amendment with the landlord and the tenants already there: they are then on the lease. The co-tenant who leaves has given notice, and the amendment records it.
If the lease provides for joint liability, the leaving co-tenant's and their guarantor's ends on the date their notice takes effect once a new co-tenant is on the lease, and at the latest six months after that date (article 8-1 VI).
A parking space or a garage
A garage or parking space let with the home, as an accessory, by the same landlord falls under the same rules as the home (article 2 of the law of 6 July 1989).
The amendment describes the space and its rent, which is added to the rent of the home.

The lease amendment: your questions.
No: the yearly review the lease provides for is a request from the landlord to the tenant, without an amendment. The rent review letter template works it out.
Yes: an amendment records a change agreed by both sides. Without every party signing, the lease goes on as it is.
Not for an unfurnished let: article 17-1 III of the law of 6 July 1989 forbids the increase for works in a home rated F or G. The tool refuses it for a furnished let too.
If the lease provides for joint liability, yes, with their guarantor, until a new co-tenant is on the lease, and at the latest six months after their notice takes effect (article 8-1 VI). The tool works out that date.
