Casa Pronta, notary or authenticated private document: how completion routes differ

The route is formalisation, not buyer due diligence

Portuguese property transfers can be completed through different formal routes. The parties may use Casa Pronta, a notary, or an authenticated private document prepared and authenticated by an authorised professional.

Each route can be valid. None of them removes the need for the buyer to review the property, contract, payment and completion conditions beforehand.

Casa Pronta

Casa Pronta is an official one-stop service for procedures connected with acquisition and registration. It can handle purchase contracts, mortgage-related acts and registrations in one coordinated setting.

It is often practical when the file is complete and the required parties and banks can work within the service's process. The buyer should still confirm which documents must be submitted, who will attend, how taxes and fees will be paid and whether the specific mortgage or power-of-attorney arrangements are accepted.

Casa Pronta staff perform a public formalisation and registration function. The service is not the buyer's privately instructed legal adviser.

Notarial completion

A notary may formalise the purchase through a public deed. The notary verifies formal requirements and executes the instrument within the applicable legal framework.

The parties need to agree who coordinates the draft, supporting documents, seller mortgage cancellation, bank attendance and registration. A notary does not automatically negotiate the contract or investigate every commercial risk for one side.

Authenticated private document

A property transfer can also be documented through an authenticated private document. For registration purposes, the document must be properly authenticated and deposited through the required electronic process.

Lawyers, solicitors and notaries may perform relevant authentication functions where legally authorised. The buyer should ask who is preparing the document, who represents each party and who is responsible for deposit and registration.

How to choose

The route may depend on:

• whether the buyer has a mortgage;
• whether the seller has a mortgage to cancel;
• location and availability of participants;
• use of a power of attorney;
• language and translation arrangements;
• complexity of the property file;
• bank requirements;
• timing and registration coordination.

The cheapest or fastest route is not automatically the best one if the document file or payment mechanics are not ready.

Documents to confirm before the appointment

Review the final transfer document, updated land-registry information, tax description, identification, marital-status information, company or representative authority, energy certificate and any use-licence or technical documentation required for the property.

For an apartment, confirm the condominium declaration and understand the consequence of any proposed waiver. For a mortgaged property, confirm the bank documents and the agreed route for removing the seller's charge.

Payment control

Create a written completion statement showing the balance due, taxes, fees, bank settlement amount and any adjustment for condominium charges, rent, deposits or agreed repairs.

Verify every IBAN through an independent channel. If part of the money is paid directly to the seller's bank, the buyer should understand why and receive evidence supporting the discharge and cancellation process.

Power of attorney and remote attendance

The chosen venue must accept the form and scope of any power of attorney. Confirm authentication, apostille or consular formalities, translation and registration requirements in advance.

If the representative can sign both purchase and mortgage documents, the authority should be checked against both sets of acts. A power accepted by one participant may still require clarification from another.

Registration after signature

Casa Pronta integrates registration within its service. In other routes, confirm who submits the acquisition and mortgage registrations, what evidence the buyer receives and how the final result will be monitored.

The permanent land-registry certificate can be used to follow the legal position. Keep the submission details and final registration evidence in the completion file.

Buyer-side conclusion

Choose the completion route only after the transaction requirements are mapped. The venue is a delivery mechanism. Buyer protection comes from a reviewed contract, complete supporting evidence, controlled payment and a documented path to clean registration.

Use Final Deed and Completion Review when the buyer wants the final package checked before the balance is released.
