If you’re renting in Portugal, the contract matters far more than in other countries. Portuguese tenancy law is quite structured, and small details around duration, renewal and notice periods make a big difference.
Fixed-term rental contracts
This is the most common type for residential lets.
Fixed-term residential leases must normally last at least 1 year (and no more than 30 years).
If a shorter duration is stated, it will generally be treated as 1 year unless the tenant expressly requested the shorter term or the lease is genuinely for temporary housing, with the reason clearly stated in the contract.
Even if a fixed-term contract is signed for 1 year, it must normally be capable of renewing until the tenancy reaches at least 3 years in total.
Exceptions: the tenant objects to renewal or the landlord relies on a legally recognised ground.
Leases for non-permanent purposes, such as study, professional relocation or temporary assignments, may be agreed for shorter periods, but the temporary nature must be clearly justified in writing.
If it is not, the contract may be treated as permanent housing under the standard rules.
Automatic renewal
Unless the contract explicitly excludes renewal, fixed-term contracts renew automatically at the end of the term. The renewal period is usually equal to the initial term, unless the contract specifies otherwise
Notice to prevent renewal
Notice periods depend on the length of the contract and how long the tenancy has been running. There isn’t one universal rule.
For landlords opposing renewal of a fixed-term residential contract:
- 240 days’ notice for contracts lasting 6 years or more
- 120 days’ notice for contracts lasting between 1 and 6 years
- 60 days’ notice for contracts lasting between 6 months and 1 year
- 30 days’ notice for contracts lasting less than 6 months
For tenants terminating a fixed-term contract early (without alleging breach):
- At least one-third of the initial contract duration must have passed.
Once that point is reached, the tenant may terminate at any time by giving minimum notice of:
- 120 days if the contract term is 1 year or more
- 60 days if the contract term is less than 1 year
Early termination
There are two main legal routes when terminating a lease:
Denúncia – termination without alleging breach, following notice rules.
This means ending the contract without claiming the other party has done anything wrong.
Resolução – termination due to breach
This applies when one party fails to comply with the contract. The most common example is non-payment of rent, but it can also include serious misuse of the property or other contractual breaches.
Open-ended (non-fixed-term) contracts
These have no fixed end date.
Tenants can terminate with notice, and the period depends on how long they’ve lived in the property. In most cases, expect around 120 days’ notice, though this varies depending on circumstances and contract wording.
Landlords can only terminate open-ended contracts under specific legal grounds, such as:
- The property is needed for their own permanent residence or for a close family member.
- Major renovation or demolition works that require the property to be vacant.
