Power of Attorney to Sell Property in Portugal: Requirements and Safeguards

Confirm the required form before signing

Article 262 of the Portuguese Civil Code describes a power of attorney as the act by which someone voluntarily grants representative powers. Unless the law provides otherwise, it should use the form required for the transaction the representative will carry out. A Portuguese property sale itself must be completed by public deed or authenticated private document under Article 875 and Decree-Law 116/2008.

The formal requirements for the sale and the power of attorney must be checked separately. Article 116 of the Notarial Code sets out options for powers requiring notarial involvement, with stricter rules where the representative or a third party also has an interest. Ask the professional who will accept the document to confirm which option applies.

Ask the Portuguese lawyer, solicitor or notary handling the sale to approve the final wording and signing arrangements before the owner signs. A document that is valid in the country where it was signed may still need an apostille or legalisation, a certified translation or another formality before it can be used in Portugal.

Identify the property, the people and the permitted acts

The draft should identify the owner, the attorney and the property precisely enough for the intended transaction. Confirm whether the authority covers only the final transfer or also negotiation, a reservation, the CPCV, amendments, delivery of possession, tax and registry declarations, mortgage discharge and receipt of documents.

Do not assume that a broad phrase covers every step. Conversely, do not grant powers that will not be used. The receiving professional should compare the draft with the current land register, the parties' identification and the planned sale structure.

• Property description and land-registry identifiers
• Authority to agree or change the price and other material terms
• Authority to sign a reservation, CPCV and final transfer
• Authority to deal with the bank, tax authority and land registry
• Authority to receive keys, documents, deposits or sale proceeds
• Any right to appoint a substitute attorney

Decide separately who can receive the money

You can authorise someone to sign the sale documents without authorising them to receive money. Specify whether the attorney may receive a reservation payment, deposit or completion proceeds, endorse a cheque, give a receipt or designate the receiving account. Where possible, the contract and completion statement should set out how payments will be made before the signing date.

Bank-detail fraud is a practical risk in remote transactions. Confirm any new account instruction through a second trusted channel using contact details already known to the parties. An emailed change should never be accepted merely because the message contains correct property information.

Signing outside Portugal

A Portuguese consular post may be able to prepare or authenticate the power of attorney. Contact the relevant post to confirm who can use the service, what identification and draft wording it needs, and whether an appointment is required. Procedures differ between posts, so check the proposed arrangements with the professional receiving the document in Portugal.

A locally notarised document may also be usable, depending on the country, the wording and the transaction. Ask the professional who will rely on it in Portugal whether an apostille under the Hague Convention, consular legalisation and a certified Portuguese translation are required. Obtain that answer before the appointment rather than after sending the original by courier.

Limit duration, substitution and conflicts

Consider an expiry date or a clear end point linked to the named sale. Decide whether the attorney can appoint someone else and whether any act involving the attorney personally is permitted. Irrevocable language or authority to act on both sides deserves transaction-specific legal advice; it should never appear simply because it was present in a template.

Keep a signed copy, the approved draft, proof of how it was authenticated and a record of every original delivered. If the owner later wants to revoke or replace the authority, obtain advice immediately and notify the people and institutions who may still rely on it. Portuguese law provides registration and consultation mechanisms for certain powers of attorney and their termination.

Verify the attorney and every high-risk instruction

Before documents or keys are released, independently verify the attorney's identity and contact details. The owner should receive copies of the CPCV, final draft, completion statement and bank calculations with enough time to review them. Material changes to price, buyer, payment route or completion date should require fresh written confirmation unless the owner deliberately authorised a wider discretion.

The representative can prepare the documents while the owner or an independent adviser confirms the final terms through a trusted means of contact. Separating those responsibilities helps protect both the owner and the representative from last-minute impersonation or misunderstanding.

Owner checklist before granting authority

A power of attorney allows someone to act in your absence. Title, planning, mortgage, tax and contract checks are still needed. Use this checklist when briefing the qualified professional responsible for the sale.

• Confirm the exact acts and the legally accepted form
• Match names and property identifiers to current records
• Approve the price, amendment and money-handling powers separately
• Decide whether substitution is allowed and set an end point
• Confirm apostille, legalisation and translation before signing abroad
• Use a second channel for identity and bank-detail verification
• Retain copies, delivery records and the final completion statement
• Take independent Portuguese legal advice for the actual transaction
