NIE, bank account, power of attorney: the order that saves you a trip.
Three practical building blocks can determine whether an international purchase moves smoothly: the NIE, banking and source-of-funds preparation, and, when useful, a power of attorney. They are not three universal legal prerequisites, but leaving them too late can turn a straightforward purchase into a long one.
Start the paperwork before you choose the property, not after.
A Spanish purchase can complete quickly once the documents exist. The bottleneck is almost never the seller — it is a NIE appointment, a bank’s compliance review, or a power of attorney that has to travel abroad for an apostille.
Buyers who obtain a NIE and appoint a lawyer while they are still viewing put themselves weeks ahead. Buyers who wait until an offer is accepted usually lose the reservation deadline.
The NIE is an identifier, not a residence permit.
Le Número de Identidad de Extranjero is the number the Spanish administration uses to identify you for any legal or fiscal act: buying property, paying tax, signing utility contracts, opening a bank account. Holding one gives you no right to live in Spain. This is the single most common misunderstanding we encounter.
There are three routes. Apply in person in Spain at a Policía Nacional foreigners’ office, apply at the Spanish consulate in your country of residence, or have a lawyer apply on your behalf under a power of attorney. The paperwork is the EX-15 application plus the corresponding fee form; your lawyer will confirm the current version and amount.
The bank account is an anti-money-laundering exercise.
Spanish banks routinely work with non-resident buyers, but anti-money-laundering rules mean they may ask for identification, tax-residence information and evidence showing where the purchase funds come from — for example employment income, a business sale, an inheritance or a prior property disposal. Exact onboarding documents vary by bank and customer profile.
A Spanish account is often convenient for completion, utilities and ongoing property costs, but it is not universally mandatory. The deed must identify the agreed means of payment, which can include bank transfers or cheques. Confirm the payment mechanics early with your lawyer, bank and notary so compliance checks and international transfers do not become the bottleneck.
The power of attorney is what buys back your calendar.
A Spanish poder notarial lets your lawyer sign on your behalf: obtain the NIE, open the account, sign the deed at the notary, register the property and set up utilities. For a buyer living abroad it removes the need to be physically present at completion.
It can be granted before a Spanish notary while you are in Spain. Abroad, it may also be granted before a Spanish consular officer, or before a local notary with the apostille or legalisation and translation required for use in Spain. The correct route depends on the country and document format, so the Spanish lawyer who will use the power should approve the wording first.
The power should be drafted narrowly, limited to the transaction in question. A general power over all your Spanish affairs is rarely necessary and should not be signed casually.
The order that works.
| Stage | What happens | Who does it | Typical friction |
|---|---|---|---|
| 1. Independent lawyer | Engage a Spanish lawyer who does not act for the seller or the agency | You | None — but do it first, not last |
| 2. Decide on power of attorney | If your lawyer will obtain the NIE or sign later steps for you, put the required authority in place first | You, your lawyer and a notary or Spanish consulate | Wording, apostille/legalisation and translation where required |
| 3. NIE | Application in Spain, at a Spanish consulate, or through an authorised representative | You or your authorised representative | Appointment and processing availability |
| 4. Bank account | Non-resident account opened, source of funds documented | You or your lawyer | Compliance review |
| 5. Reservation and arras | Property taken off market; deposit contract signed, commonly around 10% | Lawyer | Signing before legal due diligence is complete |
| 6. Due diligence | Land Registry check, debts, licences, community charges, planning status | Lawyer | Undeclared extensions and outstanding charges |
| 7. Notary and completion | Deed signed, funds delivered, keys handed over | Notary | Banker’s draft timing |
| 8. After completion | Taxes filed, Land Registry entry, utilities and IBI transferred | Lawyer | Deadlines for filing purchase tax |
The paperwork exists so this part is uneventful.
Four things that cost buyers months.
Using the seller’s lawyer
The agency’s recommended lawyer may be excellent, but your lawyer should owe a duty to you alone. Appoint independently.
Signing arras too early
Do not assume a reservation payment or arras deposit is automatically refundable or non-refundable. The consequences depend on the contract and the type of arras used. Have an independent lawyer review the wording before you sign or transfer money.
Leaving funds abroad
Currency conversion and international transfers have their own timetable. Completion dates are missed over this more than anything else.
Assuming NIE equals residency
It does not. Residence is a separate application on separate grounds, and buying property is not one of them since April 2025.
This article cannot answer your case.
Everything above is general information, current at the date of last review. It is not legal, immigration or tax advice, and it does not create a client relationship.
Procedures, forms and fees differ by province and consulate and are updated regularly. The right structure for your purchase also depends on your residence status, marital regime and how you intend to hold the property.
Before signing anything, take an individual consultation with a Spanish lawyer and a tax adviser, with your own documents in front of them. HOMESEE can introduce you to independent professionals on the Costa del Sol and in Valencia.
The documents are simple. The calendar is not.
Nothing in this sequence is legally complex. What catches buyers out is that each step depends on the one before it, and three of them are controlled by institutions with their own queues.
Begin the NIE and the lawyer appointment while you are still comparing properties. By the time you find the right one, the only thing left to negotiate is the price.
