Rental contract termination based on lack of permanent residence is valid without a minimum duration requirement.

The Tribunal da Relação de Lisboa confirmed the lower court's decision terminating a residential lease due to the tenant's lack of permanent residence. The tenant argued that no minimum duration of absence was required to justify such termination, but the court rejected this procedural objection. The court ruled that the effectiveness of the lack of permanent residence as a termination ground does not depend on the existence of any minimum duration for such absence.
