How many days notice must a landlord and tenant give each other to terminate a lease that does not run for a definite duration?

A lease that does not run for a definite duration is typically considered a month-to-month lease. In many jurisdictions, the standard requirement for terminating a month-to-month lease is for either the landlord or the tenant to provide notice at least 30 days prior to the intended termination date. This advance notice allows both parties ample time to make necessary arrangements, such as seeking alternative housing or preparing the property for re-rental.

In contrast, shorter notice periods could lead to abrupt terminations, while longer notice periods are generally not mandated in typical situations involving month-to-month rentals. Therefore, a 30-day notice aligns with common legal practices regarding the termination of indefinite leases.
