Lease Renewal and Renegotiation in Portugal: Rules, Timelines, and Strategies

In Portugal, most residential leases are fixed-term contracts (contrato a prazo certo) that renew automatically at the end of their initial term. Under Art. 1096º of the Civil Code, a fixed-term lease renews for successive periods equal to the initial duration — with a minimum renewal period of 1 year.

For example, a 2-year lease automatically renews for another 2 years. A 6-month lease renews for 1 year (the minimum). This automatic renewal continues indefinitely until one party formally opposes it.

Either party can prevent automatic renewal by sending a written notice of opposition (oposição à renovação) within the legally required timeframe.

Landlord opposition (Art. 1097º): - Lease of 6+ years: 240 days notice before the renewal date - Lease of 1–6 years: 120 days notice - Lease of 6–12 months: 60 days notice - Lease under 6 months: one-third of the term notice

Tenant opposition (Art. 1098º): - Lease of 6+ years: 120 days notice before the renewal date - Lease of 1–6 years: 90 days notice - Lease of 6–12 months: 60 days notice - Lease under 6 months: one-third of the term notice

Important restriction (Lei 13/2019): The landlord's opposition to the first renewal is only effective after the lease has been in force for at least 3 years. This means on a 1-year lease, the landlord cannot oppose the first renewal — the tenant is guaranteed at least 3 years of occupancy.

All opposition notices must be sent by registered letter (carta registada com aviso de receção).

Automatic renewal preserves the existing terms of the lease — the rent, duration, and conditions carry over unchanged. If either party wants to change the terms, they must renegotiate before the renewal takes effect.

Rent at renewal: - Renewal itself does not change the rent — the only automatic adjustment is the annual INE-coefficient update (1.0224 for 2026), applied with 30 days' written notice. - The Mais Habitação (Lei 56/2023) 2% cap governs a different situation: the initial rent of a NEW contract on a property rented in the last 5 years (last rent × 1.02, plus legally allowed additions). It does not cap renewals of an ongoing contract. - For any increase beyond the annual update, both parties must agree in writing. The landlord cannot unilaterally raise the rent above it.

Other terms: - To change non-rent terms (e.g., pet policy, subletting rights, maintenance responsibilities), both parties must sign a written addendum (aditamento) to the lease. - If the parties cannot agree on new terms, the existing terms continue unchanged upon renewal. - The landlord cannot make renewal conditional on the tenant accepting new terms — the existing contract renews automatically.

CompliantLease generates a comprehensive term and renewal clause (Clause 3) that specifies the initial term, the renewal mechanism under Art. 1096.º, and the exact opposition deadlines for both landlord and tenant under Art. 1097.º and 1098.º. The annual rent update clause is included with the INE coefficient reference and the correct legal citations. All text is bilingual and legally cited.
