How BAS Works: The Tenant and Landlord Desk

BAS is the service that handles special evictions in Portugal. Knowing what it does — and what it requires — prevents delays and rejected applications.

The problem

Most landlords only hear about BAS when they already have a problem. They arrive without complete documentation, submit applications with errors, and waste weeks on corrections.

What BAS does

• Receives the eviction application and verifies formal compliance.
• Notifies the tenant and manages opposition deadlines.
• Issues the title for vacating the property when there is no valid opposition.
• Forwards contested cases to court.

What to have ready before submitting

• Lease agreement, ideally registered with the Tax Authority (AT).
• Proof of communication of termination to the tenant.
• Calculation of outstanding rent.
• Payment of the applicable fee.

Start with the right foundation

Every rejected application means another month of lost rent. A registrable and well-drafted contract is the starting point that shortens the entire process.
