Final answer:
The legal notice needed to terminate a tenancy at will is determined by the terms of the lease agreement. For residential tenancies, the notice requirements can vary by state, while for non-residential tenancies, they are usually governed by the lease agreement.
Step-by-step explanation:
The legal notice needed to terminate a tenancy at will is determined by the terms of the lease agreement. In general, either party can terminate the tenancy by giving a written notice of intention to terminate, usually 30 days in advance. However, certain laws may require the landlord to have a 'just cause' for termination, in which case the notice should state the specific reason for termination.
For residential tenancies (RES), the notice requirements can vary by state. Some states may require a longer notice period or have specific requirements for terminating a tenancy at will. It is important to refer to the specific laws of the state where the property is located to determine the correct notice to give.
For non-residential tenancies (NON RES), the notice requirements are usually governed by the lease agreement between the landlord and tenant. The lease agreement may specify a notice period and any other conditions for termination.
