Final payment and key handover in Portugal: controls before the balance leaves

The final transfer should follow a verified checklist

By completion, the buyer may feel that the transaction is already decided. That is precisely why final payment deserves a separate control process. Most of the price leaves at the moment the buyer has the least practical leverage to correct an error.

No balance should be released simply because an appointment has been booked.

Compare the final instrument with the CPCV

Review the deed or authenticated private document before the signing. Confirm the parties, property, price, payment history, balance, covered rights and any declarations about possession or charges.

If the final document differs from the CPCV, identify the reason and approve the change explicitly. Completion is not the right time to discover a new clause through oral translation.

Refresh the property position

Obtain current land-registry information close to completion. Check ownership, charges and pending registrations. Confirm the mechanism for removing the seller's mortgage and any other item that should not remain after the sale.

For an apartment, review the condominium declaration and any waiver language. Confirm allocation of approved works or charges that were negotiated in the CPCV.

Verify seller and representative authority

Reconfirm identity and authority on the completion date. Company powers, marital status, inheritance documents or powers of attorney may have changed since the CPCV.

A power of attorney should cover the exact act, and the professional formalising the transaction should confirm its accepted form in advance.

Prepare a completion statement

The buyer should have one written calculation showing:

• purchase price;
• amounts already paid;
• final balance;
• any bank settlement amount;
• taxes and registration fees;
• agreed adjustments;
• account details and payment method.

Reconcile the statement with the contract and bank documents. Unexplained last-minute changes should pause payment.

Verify every payment instruction

Confirm IBANs through a second communication channel using known contact details. Do not rely only on a forwarded email or a message received shortly before completion.

If money is split between the seller and a lender, understand the legal purpose of each transfer and the evidence that will follow.

Coordinate the mortgage closing

Mortgage buyers should confirm the approved loan amount, buyer contribution, bank attendance or remote process, insurance, mortgage instrument and registration sequence.

The seller's bank may need to provide a settlement and cancellation document. The buyer's bank may impose conditions that must be satisfied before funds are released. Put these requirements on the same checklist.

Confirm taxes and formalisation documents

Check the acquisition tax and stamp-duty evidence required for completion, together with identification, fiscal information and property documents.

The formalisation route may be Casa Pronta, a notary or an authenticated private document. Each route should have a named person responsible for document preparation, signature and registration.

Define the handover moment

The contract should state when the buyer receives possession and keys. Record all keys, access cards, remotes, parking devices and storage access.

Photograph electricity, water and gas meters. Keep a signed or acknowledged handover record with the date, readings, covered items and visible defects.

Deal with unresolved repairs and defects

If work remains incomplete, do not rely on a general promise to fix it later. Use a written list, deadline and evidence standard. Depending on the agreement, the buyer may need a retention, escrow arrangement, price adjustment or postponement.

For new build, combine legal completion review with technical snagging and warranty documentation.

Confirm registration and post-completion delivery

Before leaving, know who submits acquisition and mortgage registration, what submission evidence the buyer receives and when the final registered position will be checked.

Also list documents to be delivered after completion, such as updated certificates, original guarantees or final bank releases.

Final Deed and Completion Review helps the buyer convert these points into a written go, pause or correction decision. The final payment should be the last verified step, not an act of trust under time pressure.
