A month-to-month tenancy is a periodic tenancy or lease in which the tenant is given possession of the leased premises with no specific expiration date and agrees to pay the landlord on a monthly basis. A month-to-month tenancy often requires the tenant or the landlord to give the other party 30 days written notice of termination of the lease.

Both residential leases and commercial leases may be month-to-month tenancies. If a residential or commercial tenant remains in the leased premises and continues to pay rent following the expiration of a lease for a longer term, there may be a new month-to-month tenancy created and recognized by law.

In Wyoming, a month-to-month tenancy is recognized as a form of periodic tenancy where the tenant occupies the property without a definite lease term but continues to pay rent on a monthly basis. This arrangement does not have a specific end date and can continue indefinitely until either the tenant or the landlord decides to terminate the tenancy. To end a month-to-month tenancy, Wyoming law typically requires either party to provide the other with a 30-day written notice. This notice period allows both the tenant and the landlord to make necessary arrangements for the transition. If a fixed-term lease expires and the tenant remains in the property with the landlord's consent, and rent continues to be paid and accepted, this can lead to the establishment of a month-to-month tenancy. This applies to both residential and commercial leases in Wyoming. It's important for both parties to understand their rights and obligations under this type of tenancy to ensure compliance with state statutes and to protect their respective interests.
