Your First 3 Weeks
NIE, Bank Account and Power of Attorney in 3 Weeks
Follow one overseas buyer through the first 21 days of arranging an NIE, Spanish bank account and limited power of attorney for a home purchase.
Week 1: Start With the NIE
EX-15 Form
The application states why you need a foreigner identity number.
790 Fee Form
Pay the code 012 fee and keep the stamped or electronic receipt.
5-Day Decision
The official maximum is five days after the competent office registers a complete application.
On day 1, Anna has a choice: wait until she finds a home, or start the paperwork before viewings become serious. She applies now. Anna is a composite buyer, but the decisions and documents in her timetable are the ones overseas buyers face in practice.
An NIE, or Número de Identidad de Extranjero, identifies a foreigner dealing with Spanish authorities. It isn't residency and it doesn't give anyone permission to live in Spain. For a buyer, its job is practical: the number follows the tax, banking and notarial records connected with the purchase.
Anna's lawyer checks her completed EX-15 form, passport copy, reason for applying and proof that the Modelo 790 Código 012 fee has been paid. Spain's National Police says an applicant can file through an immigration office or police station in Spain, or through a Spanish consulate when abroad. Its official NIE procedure sets a maximum decision period of 5 days after the competent office registers the application.
That five-day period doesn't promise an appointment within five days. Appointment availability and consular handling can add time before the application is registered. Anna therefore asks one question before booking flights: which office will accept her case, and what is the earliest workable route? By day 5, her application is lodged and the receipt is saved with her purchase file.
Week 2: Prepare the Bank File
On day 8, Anna has the NIE confirmation and turns to the bank account. She could postpone it because a Spanish account isn't a universal legal condition for buying a home. She opens one anyway. It gives her a local IBAN for community fees, utilities and taxes after completion, and it separates property payments from everyday spending at home.
The account isn't automatic. According to the Banco de España's customer guidance, an EU citizen may be asked for a passport or national identity card together with an NIE. A non-resident must also prove that status. The bank can request evidence of employment, income, tax residence and the source of money entering the account to meet anti-money-laundering rules.
Anna sends one orderly file: identification, NIE, address evidence, tax identification from her home country, recent income evidence and statements tracing the deposit savings. The exact list differs by bank and customer. Her decision is to answer the source-of-funds questions now instead of moving a large sum first and explaining it later.
By day 12, the account is open, but Anna doesn't treat the first quoted package as fixed. She reads the fee information and checks the maintenance charge, card cost, transfer limits and conditions for avoiding fees. The Banco de España notes that ordinary payment accounts depend on the bank's commercial decision. If an eligible EU resident struggles to open one, a basic payment account is a separate product to ask about, subject to identity and anti-money-laundering checks.
Week 3: Set the Limits
On day 15, Anna decides whether she wants to return to Spain for every signature. She expects to attend completion if dates work, but doesn't want a delayed flight to put the contract at risk. Her answer is a limited power of attorney for the purchase.
A power of attorney is a notarised public document appointing someone to act for you in specified legal matters. Anna asks her independent lawyer to draft powers for the tasks she has actually approved: handling the NIE if anything remains, dealing with the purchase deed, paying related taxes and arranging utility changes. She checks whether the draft permits signing a mortgage, moving money, changing the purchase price or delegating authority to somebody else. Powers she doesn't understand are narrowed or removed.
Spain's General Council of Notaries explains that powers can be tailored to particular acts and that the representative proves their authority with an authentic copy. Its power of attorney guidance also says the person granting the power may revoke it. If Anna signs outside Spain, her lawyer confirms the required wording and whether legalisation or a Hague Apostille is needed before she books the local notary.
By day 18, Anna signs 1 limited deed, not a general authority over all her assets. She keeps a copy, records who holds the authorised copy and asks how revocation would be notified. The power is a backup for this transaction, not a substitute for reading the reservation agreement, private purchase contract or completion statement herself.
Day 21: Check What Is Ready
NIE Recorded
The number and application evidence are in the legal file, with the spelling checked against the passport.
Bank Checks Cleared
The account works, transfer limits are known and source-of-funds documents are ready before a large payment.
Authority Defined
The representative, permitted acts, document location and revocation route are written down.
Purchase Still Conditional
No administrative preparation replaces legal checks on the property or careful review of the contract.
At the end of 21 days, Anna hasn't bought a property. She has removed three avoidable sources of delay. Her lawyer can identify her in Spanish records, her bank has already examined the customer file, and a trusted representative can act within written limits if travel plans change.
The order mattered. Starting with the NIE gave the bank a stronger identification file. Preparing the bank documents exposed any source-of-funds questions before a contract deadline. Discussing the power last meant Anna could define it around the actual purchase plan rather than grant broad authority on day 1.
This timetable is a planning model, not a guaranteed service level. Consular appointments, bank compliance checks and documents signed abroad can take longer. Start before making a time-sensitive commitment, and use an independent Spanish lawyer or notary to confirm what your nationality, residence and financing route require. Our step-by-step buying guide shows where these first 3 weeks fit into the wider purchase.
