On the day of the signing at the notary, the seller must be correctly identified. The lack of a valid ID document can halt the entire transaction. It is essential to have this documentation prepared and current.

Required Identification Documents:

• Valid Passport: As a foreigner, your passport must be valid. The notary will verify your identity with this official document.
• NIE (Foreigner Identification Number): Whether you are a resident or non-resident, your NIE is absolutely mandatory. It is your tax identification number in Spain and is essential for declaring the taxes derived from the sale.

Key Advice:

Check the expiration date of your passport months in advance. If you need to renew it, do so before starting the sales process to avoid unexpected delays right before the notary appointment.
