Tenant Rights During Property Sale in Portugal: Pre-Emption and Lease Continuity

The general rule in Art. 1057º of the Civil Code is that the person who acquires the right on which the lease was based succeeds to the landlord's rights and obligations. A sale is therefore not, by itself, stated as a ground that ends the lease.

The article expressly preserves the rules of registration. That caveat matters: communicating a lease to Finanças is a tax-registration duty, while opposability to a buyer may involve land-registration rules and the facts of the particular transaction. Art. 1057º does not say that six months of possession automatically replaces registration. A landlord, tenant or buyer dealing with an unregistered lease should obtain case-specific legal advice before relying on the general succession rule.

Under Art. 1091º of the Civil Code, a tenant generally has a pre-emption right (direito de preferência) where the rented premises have been leased for more than 2 years and the landlord proposes a sale or transfer in lieu of payment. In practical terms:

Different rules and constitutional decisions can matter where the rented unit is only part of a building that is not divided into autonomous fractions. If notice was omitted or defective, a court remedy may be available under the preference regime, but the remedy, parties, evidence and deadline are legal questions. Do not describe every case as an automatic annulment of the sale.

For a sale involving a sitting tenant, both sides should separate three questions:

1. Contract succession: identify the current lease, amendments, deposit record and payment history so the buyer can assume the landlord position on an accurate record. 2. Registration and opposability: confirm both the tax communication at Finanças and any land-registration issue with the notary, solicitor or lawyer handling the sale. One does not automatically answer the other. 3. Pre-emption: determine whether Art. 1091º applies to the premises and transaction, then send a complete registered communication early enough for the 30-day response period.

The communication should reflect the actual deal. If a price is €250,000 with payment in 60 days, preference ordinarily means accepting the transaction on those communicated terms, not proposing a different price. Portfolio sales, sales of an undivided building, co-ownership and enforcement or insolvency sales can add rules that this general guide does not resolve.
