How to End Your Lease Early in Portugal — Tenant's Guide (2026)

In Portuguese rental law, denúncia pelo arrendatário is the tenant's right to unilaterally end a lease contract. There are two distinct mechanisms:

Both mechanisms require written notice delivered within legally prescribed timeframes. The rules are set out in Art. 1098º of the Portuguese Civil Code.

Art. 1098º of the Civil Code establishes the following framework:

Opposition to renewal (Art. 1098º nº 1): The tenant must give notice before the end of the current term: - Contracts under 6 months: notice = 1/3 of the contract duration - Contracts 6 to 12 months: 60 days' notice - Contracts 1 to 6 years: 90 days' notice - Contracts 6 years or longer: 120 days' notice

Early termination (Art. 1098º nº 3): Once one-third of the initial term or renewal has elapsed, the tenant may terminate early with 120 days' notice when the term is at least 1 year or 60 days' notice when it is shorter than 1 year. Under nº 5, termination takes effect at the end of a Gregorian calendar month.

Insufficient notice (Art. 1098º nº 6): Insufficient notice does not prevent the lease from ending, but generally requires payment of the rents corresponding to the missing notice period. The same paragraph contains exceptions for specified involuntary events; there is no universal two-month cap.

Form requirements (NRAU Art. 9º): - The default is a signed writing sent by registered letter with acknowledgment of receipt - Hand delivery is also permitted when the recipient signs and dates a copy - Do not rely on email as a generic substitute for the statutory form - Use the landlord's valid notification address and clearly state the intended termination date

Example 1 — Opposition to renewal: For a 1-year fixed term, the tenant must give at least 90 days' notice before the term ends to prevent renewal. Calculate the delivery deadline from the contract's actual end date rather than relying on a generic calendar example.

Example 2 — Early termination: For a 3-year term, the early-termination right becomes available after one-third of that term has elapsed. From that point, the tenant must give at least 120 days' notice and account for the end-of-calendar-month effect.

Example 3 — Short term: For a 6-month term, opposition to renewal requires 60 days' notice. Early termination is a separate route: after one-third has elapsed, it also requires 60 days' notice because the term is under 1 year.

Missing notice: If a tenant on a 2-year term gives only 30 of the required 120 days for early termination, Art. 1098º nº 6 generally requires payment of the rents corresponding to the missing notice period, subject to its statutory exceptions.
