Eviction in Portugal: BAS Procedure, Tenant Opposition and Landlord Rights

An eviction in Portugal is not simply a landlord telling a tenant to leave.

A lawful eviction normally begins with a valid legal reason why the lease has ended.

Only after that does the possession-enforcement question arise.

Portugal has a special rental procedure called the Procedimento Especial de Despejo, or PED, handled through the Balcão do Arrendatário e do Senhorio, BAS.

This procedure can be faster than an ordinary civil action in qualifying cases, but it still has formal requirements and tenant opposition rights.

What is BAS?

BAS is the Balcão do Arrendatário e do Senhorio.

It operates nationally and handles special rental procedures including:

• Procedimento Especial de Despejo, PED;
• Injunção em Matéria de Arrendamento, IMA.

PED is the eviction-side procedure.

IMA is used for defined rental obligations and tenant rights.

They are different.

What is PED?

PED is a special procedure intended to make effective the vacation of a rented property after the lease has already ended through a legally recognised route.

The key phrase is:

after the lease has ended.

A landlord should not use PED to avoid proving that a valid termination title exists.

What situations can support PED?

The NRAU statutory framework recognises defined titles arising from lease termination.

Depending on the facts, these can include situations involving:

• agreement ending the lease;
• opposition to renewal;
• expiry;
• landlord termination under an applicable statutory route;
• resolution for rent arrears or another recognised ground;
• other termination titles admitted by Article 15.

The exact documents depend on the route.

Rent arrears

Unpaid rent is one of the most common reasons an eviction dispute begins.

But the landlord still needs to use the correct termination and notification framework.

A debt claim and the possession claim can also interact.

Do not confuse:

• amount of unpaid rent;
• validity of lease termination;
• entitlement to possession.

They are connected but legally distinct issues.

Can the landlord just change the locks?

A landlord should not replace the legal possession procedure with self-help.

Changing locks, removing belongings or using utilities pressure can create serious legal problems.

Where the tenant has not voluntarily returned possession after the lease ends, use the statutory possession/eviction route.

The fact that the landlord owns the property does not make the tenant's possession legally irrelevant.

What happens when the tenant is notified?

Article 15-D provides the statutory notification framework.

The tenant is informed of the eviction claim and the legal response options.

The deadlines are short.

Do not ignore a BAS notification.

How long does the tenant have to oppose?

Under Article 15-F, the tenant generally has 15 days from notification to submit opposition through the BAS procedure.

Depending on the case, the tenant may also need to:

• pay amounts;
• provide security;
• request legally available deferment;
• provide supporting evidence.

Missing the opposition period can materially change the tenant's position.

What can the tenant argue?

The defence depends on the landlord's asserted termination title.

Issues can include:

• lease was not validly terminated;
• notice period was wrong;
• communication was defective;
• rent debt is incorrect;
• payment was made;
• landlord is relying on the wrong termination route;
• procedural requirements were not met.

Do not file a generic statement saying only:

"I oppose the eviction."

The legal and factual defence should address the actual title.

Security in some rent-arrears cases

For certain PED cases based on rent arrears, Article 15-F contains a security requirement connected to opposition.

The statutory formula can require a caução up to the value of six rents.

The legal-aid framework can create an exception in the applicable circumstances.

This is a procedural security requirement.

It is not the same thing as the original rental deposit.

Does opposition stop the eviction automatically forever?

No.

Opposition moves the dispute into the applicable contested procedure.

The court can then determine the relevant issues.

A tenant should not interpret filing opposition as a guarantee of indefinite possession.

A landlord should not interpret opposition as proof that the tenant is acting unlawfully.

It is part of the statutory process.

Can the tenant request more time to leave?

Portuguese rental procedure contains specific deferment mechanisms in qualifying residential cases.

The availability and conditions depend on the procedural situation.

Do not assume every tenant automatically receives an extension.

If additional time is essential, address it within the statutory period.

Ending the lease correctly comes first

Many failed eviction cases begin earlier.

The landlord may have:

• used the wrong notice period;
• sent notice to the wrong address;
• misunderstood renewal;
• treated a request as termination;
• relied on a contractual clause inconsistent with mandatory law.

Before PED, review how the rental contract ended.

Our guide to ending a rental contract in Portugal explains the residential notice framework.

Fixed-term non-renewal

A landlord can oppose renewal of a qualifying fixed-term residential lease, but the notice period depends on the lease duration.

The current Civil Code uses periods such as:

• 240 days;
• 120 days;
• 60 days;
• one-third of the term,

depending on the contractual term.

There is also a rule affecting when the landlord's first opposition to renewal becomes effective.

These details matter before an eviction is filed.

Tenant termination

A tenant can also end a residential lease through statutory opposition-to-renewal or termination routes.

If the tenant gives valid notice and fails to vacate at the end, possession can become the next legal issue.

The landlord should preserve:

• tenant communication;
• termination date;
• payment record;
• inspection arrangements;
• key-return communications.

What documents should a landlord keep?

Depending on the case:

• signed lease;
• tax registration / legally required contract evidence;
• termination notice;
• proof of delivery;
• rent ledger;
• bank statements;
• communications;
• BAS filing;
• property registry evidence;
• power of attorney where represented.

The exact PED documentary title depends on the termination route.

What should a tenant preserve?

• lease;
• landlord notice;
• envelope / delivery evidence;
• rent payment evidence;
• communications;
• proof of repairs or disputes if relevant;
• BAS notification;
• legal-aid evidence where relevant.

Do not rely on screenshots alone if original messages or emails can be preserved.

Deposit is separate

A rental deposit in Portugal should not be confused with:

• PED opposition security;
• unpaid rent;
• compensation for overstaying;
• damage claims.

The final financial account can contain several separate items.

The deposit does not automatically settle the entire eviction dispute.

Landlord claims after the tenant leaves

Vacating the property may solve possession.

It does not automatically resolve:

• unpaid rent;
• damage;
• utilities;
• deposit balance;
• court costs;
• contractual claims.

Those issues may continue separately.

A practical landlord sequence

1. Identify the termination route

Do not begin with eviction.

2. Check notice and documents

Was the lease validly ended?

3. Calculate amounts separately

Rent, deposit, damages and other claims.

4. Send the correct communication

Preserve delivery proof.

5. File the correct BAS/PED application

Use the correct termination title.

6. Prepare for opposition

A contested case needs evidence.

7. Do not use self-help possession

Follow the legal route.

A practical tenant sequence

1. Read the BAS notification immediately

The response period is short.

2. Identify the landlord's asserted title

Non-renewal, arrears or another route?

3. Check the dates

Notice and termination timing.

4. Collect payment proof

Especially where arrears are disputed.

5. Check opposition security and legal aid

Where applicable.

6. File within the statutory period

Do not wait for informal negotiations to finish.

Common mistakes

Landlord: filing eviction before validating lease termination

The possession claim rests on the termination title.

Tenant: ignoring BAS mail

The statutory response period continues.

Landlord: changing locks

Ownership does not authorise private self-help eviction.

Tenant: assuming opposition means permanent right to stay

The dispute still has to be decided.

Mixing rental deposit and PED security

They are different legal concepts.

Frequently asked questions

How long does a tenant have to oppose PED?

The general Article 15-F period is 15 days from notification.

Can PED also involve unpaid rent?

The statutory procedure can interact with rent-debt claims in the qualifying framework.

Can a landlord evict without BAS or court?

Do not use self-help. The correct legal route depends on the lease termination title and facts.

What if the notice ending the lease was invalid?

That can undermine the possession route and should be raised promptly.

Is the six-rent security always required?

No. It applies in the defined statutory rent-arrears opposition framework and legal-aid rules can matter.

Can the tenant ask for extra time?

Specific deferment mechanisms exist in qualifying cases.
