Lease amendment

A lease amendment is a short, signed document that changes one or more terms of an active lease without throwing out the rest. Amendments are used to raise rent mid-term by agreement, extend the end date, add or remove a co-tenant, change the pet rules, or fix an error in the original contract. Every party to the original lease must sign.

Sample wording

LEASE AMENDMENT
This Amendment, dated [date], modifies the Lease dated [original date] between [Landlord] and [Tenant] for the premises at [address].

1. Section [X] (Rent) is amended to read: "Monthly rent shall be $______ beginning [effective date]."
2. All other terms and conditions of the Lease remain in full force and effect.

Landlord: _______________ Date: ________
Tenant: _______________ Date: ________

Common reasons to amend

Rent increase by mutual agreement inside a fixed term.
Term extension of an existing lease by a few months.
Adding a new co-tenant after a roommate moves in.
Removing a co-tenant after a break-up or relocation.
Clerical correction (misspelled name, wrong date, wrong unit number).

What an amendment cannot do

An amendment cannot waive a non-waivable statutory right — for example, a tenant cannot "amend" the lease to give up the implied warranty of habitability, and a landlord cannot amend into a deposit above the state cap. Those clauses are void even if signed.

India practice

In India, a mid-term change to a registered leave-and-license agreement is often done by a "Supplemental Agreement" that is executed on stamp paper and, where the original was registered, re-registered. For an unregistered 11-month agreement, a signed written amendment is enough.

FAQs

What is a lease amendment?

A lease amendment is a written document that changes one or more terms of an existing, active lease — for example, the rent, the length of term, the list of occupants, or a specific clause. It must be signed by every party to the original lease to be effective.

What is the difference between a lease amendment and a lease addendum?

An amendment changes terms that were already in the original lease. An addendum adds new terms that were not in the original lease. Both are binding when signed; the distinction matters when reading which document governs a disputed issue.

Can a lease be amended verbally?

Technically possible in some states, but a verbal amendment to a written lease is almost impossible to prove. Most leases contain a "no oral modification" clause requiring every change to be in writing. Always put amendments in writing.
