You must carefully read the details of your Lease Agreement, as that document will spell out the rights and responsibilities of both the Landlord and the Tenant.
If the language within the lease allows for the landlord to end the lease with a pre-set period of notice, then such a demand for early termination of the lease would certainly be permissible.
If such termination language does not exist in the lease, a tenant can reply to the landlord’s demand with a certified letter stating that the tenants will stay until the end of the term, based upon the agreed details of the lease.
Then it will be up to the landlord and tenant to work out an agreeable solution.
Past that, for advice specific to any personal legal questions, Standard Legal always recommends you consult a qualified, licensed attorney; you can find a local attorney for FREE at Standard Legal’s Attorney Find page.
