Paying for Property in Spain: Bank Drafts, Transfers and Spanish Accounts

Buying a property in Spain does not legally require a Spanish bank account or a Spanish banker’s draft.

However, foreign buyers should arrange the payment method long before signing the public deed.

At a Spanish property completion, payment may commonly be made using:

• A banker’s draft or cheque bancario
• A TARGET bank transfer
• An instant euro transfer
• A transfer made before completion, where this has been agreed and properly documented

The right option depends on the buyer’s bank, the seller, the notary, whether a mortgage is involved and how quickly the funds must become available.

For international buyers, the real risk is not usually that Spain requires one specific payment method.

It is that the buyer reaches the notary without having coordinated the bank, source-of-funds checks and payment mechanics in advance.

That can delay or even derail a transaction.

Do You Need a Spanish Bank Account to Buy Property in Spain?

No.

Foreigners can buy Spanish property without maintaining a Spanish bank account.

A foreign account can potentially be used to fund the purchase, provided the payment is properly arranged and the transaction can be documented.

However, opening a Spanish account can make the process considerably easier.

A local account can help with:

• Property-purchase payments
• Banker’s drafts
• Mortgage payments
• Property taxes
• Community fees
• Utilities
• Home insurance
• Direct debits
• Local banking administration
• Future property expenses

The distinction is important:

Spanish account = often useful

Spanish account = not universally required by law

Foreign buyers should therefore choose a banking setup based on practicality rather than believing that Spanish ownership is legally impossible without an ES IBAN.

If you are preparing to buy, see our guide to opening a bank account in Spain.

How Is a Spanish Property Normally Paid for at the Notary?

The final purchase is normally formalized through the escritura pública de compraventa before a Spanish notary.

The deed records important information about the transaction, including the purchase price and how that price has been paid.

Depending on the payment method, information can include:

• Amount
• Payment date
• Payer
• Beneficiary
• Bank involved
• Account information
• Cheque information
• Previous payments already made

The objective is traceability.

A €500,000 purchase should not reach the notary with €500,000 of unexplained money and no clear record showing where it went.

What Payment Methods Can Be Used?

There is no single mandatory completion method.

The principal options for a typical banked transaction include:

Payment method	Main advantage	Main consideration
Banker’s draft	Funds reserved by issuing bank	Must be ordered in advance
TARGET transfer	Same-day high-value bank transfer	Bank cut-off times matter
Instant transfer	Funds can arrive within seconds	Bank must support the transaction
Earlier bank transfer	Money already received	Buyer gives up control before signing

Each method can work.

The important question is:

Which method has been agreed by the buyer, seller, banks and notary before completion day?

What Is a Spanish Banker’s Draft?

A cheque bancario is a bank-issued payment instrument.

For a property transaction, it is normally issued for a specific beneficiary and amount.

The bank ensures the corresponding funds are available for payment.

This makes bank drafts attractive to sellers because they provide a high degree of payment certainty at signing.

For example:

Purchase price: €400,000

Previously paid: €40,000

Balance at completion: €360,000

The buyer’s bank may issue a bank draft for the €360,000 balance payable to the seller.

The instrument can then be delivered when the deed is signed.

Why Are Bank Drafts Common in Spanish Property Sales?

They solve a practical problem.

The seller wants confidence that the money exists.

The buyer does not want to send the full balance days before receiving the property.

A bank draft can bridge those concerns.

The bank secures the funds before completion while the buyer retains the physical payment instrument until the transaction proceeds.

This gives the parties a clear exchange at the notary.

But “common” should not be confused with “legally mandatory.”

Is a Banker’s Draft the Same as a Personal Cheque?

No.

A personal cheque is issued by the account holder against their own account.

A banker’s draft used for completion is issued through the bank with the corresponding funds secured by the issuing institution.

That difference is why a seller may be comfortable accepting a bank draft while refusing an ordinary personal cheque for a large property purchase.

Do You Need to Order the Bank Draft in Advance?

Yes, usually.

Do not arrive at the bank on the morning of completion and assume it can instantly produce a €600,000 draft.

Ask well before signing:

• Does the bank issue property-purchase drafts?
• How much notice is required?
• Which branch will issue it?
• What beneficiary information is required?
• What fee will be charged?
• When will the amount be blocked?
• What identification must you present?
• Can your lawyer collect it under power of attorney?
• What happens if completion is postponed?
• How is the draft cancelled if the transaction does not proceed?

For a large transaction, these questions should be resolved days before the notary appointment.

Can the Bank Charge for a Bank Draft?

Yes.

Banks can charge fees for issuing and processing cheques or drafts according to their applicable conditions.

For a large property purchase, ask for the actual fee rather than assuming it will be negligible.

Compare the banker’s-draft cost against available transfer alternatives before deciding.

Can You Pay for Spanish Property by Bank Transfer Instead?

Yes.

A bank transfer can be used as the payment method for a Spanish property transaction.

The notarial documentation identifies the relevant payment details.

In 2026, transfers are particularly important because banking infrastructure now offers faster high-value options than many older property guides describe.

What Is a TARGET Transfer?

A TARGET transfer is a euro payment routed through Europe’s high-value payment infrastructure.

In Spain, buyers may still hear professionals use the older expression OMF transfer, although TARGET is now the more current terminology.

Its principal advantage for property transactions is the ability to transfer very large amounts with same-day settlement when the order is made within the bank’s applicable cut-off time.

This can be useful when hundreds of thousands of euros need to move securely on completion day.

The Important Limitation: Timing

“Same day” does not mean:

whenever you feel like sending it.

Banks have operational cut-off times.

If an order is submitted too late, settlement can move to the following working day.

That is unacceptable if the seller expects payment before completing the sale.

Therefore, verify:

• Bank cut-off time
• Amount
• Beneficiary
• IBAN
• Transaction reference
• Whether additional authorization is required
• Whether compliance has already cleared the funds
• Expected settlement timing

Do this before completion day.

Can You Use an Instant Transfer to Buy a House?

Potentially, yes.

Modern euro instant transfers can move funds within seconds, 24 hours a day.

This makes instant transfers increasingly relevant to property transactions.

The previous €100,000 limit that made them impractical for many property purchases has been removed.

A €350,000 or €500,000 property payment is therefore no longer automatically excluded merely because it exceeds €100,000.

However, your own bank may still impose:

• Customer limits
• Security limits
• Transaction controls
• Fraud checks
• Additional authentication
• Internal approval requirements

Never assume that because the payment infrastructure technically supports a large instant payment, your personal account will automatically allow one.

Beneficiary Verification Adds Another Layer of Protection

Modern euro transfers increasingly use beneficiary verification.

Before confirming the transfer, the banking system can compare the beneficiary name entered by the payer with the name associated with the receiving account.

This can help identify:

• Incorrect IBANs
• Mistyped names
• Certain payment-redirection frauds

It does not eliminate fraud risk.

But it gives buyers another opportunity to stop before sending hundreds of thousands of euros to the wrong account.

Which Is Safer: Bank Draft or Transfer?

Neither method is universally superior.

The safest method is the one properly coordinated for the specific transaction.

Bank Draft May Be Attractive When:

• Seller wants a physical guaranteed payment instrument
• Buyer wants to retain control until signing
• Spanish bank can easily issue the draft
• Completion structure is straightforward

TARGET Transfer May Be Attractive When:

• Very large amount is being paid
• Both banking arrangements support same-day settlement
• Cut-off times are known
• Seller wants money credited electronically

Instant Transfer May Be Attractive When:

• Both institutions support the necessary amount
• Buyer has confirmed transaction limits
• Immediate payment confirmation is desirable

For a complicated transaction, different parts of the price can even require different payment methods.

What If the Seller Has an Existing Mortgage?

This makes payment planning more important.

Suppose:

Purchase price: €500,000

Seller’s outstanding mortgage: €140,000

The entire €500,000 should not necessarily simply be paid to the seller without considering how the outstanding debt will be dealt with.

The completion structure may involve:

• Paying part of the price toward cancellation of the seller’s mortgage
• Paying the remaining balance to the seller
• Coordinating with the seller’s lender
• Obtaining appropriate certificates
• Arranging subsequent registry cancellation

Your lawyer, bank and notary should understand the payment structure before signing.

Why Paying the Seller Too Early Can Be Risky

A buyer may think:

“I’ll transfer the full amount several days before the notary. Then I know the money will have arrived.”

That solves the transfer-timing problem by creating another problem.

The seller now has your money before you have completed the purchase.

If something prevents completion, recovery may become more complicated.

Potential problems can arise from:

• Seller failing to complete
• Legal problem discovered before signing
• Unexpected property issue
• New attachment or enforcement concern
• Disagreement over the contract
• Banking mistake

This does not mean advance transfers are never used.

It means the timing should be contractually and legally planned rather than improvised.

Can the Notary Hold Your Money in Escrow?

Do not assume that the Spanish notary performs the same escrow function commonly associated with closing agents in some other countries.

The Spanish notary has a different role.

The notary provides public legal certainty around the deed and checks important aspects of the transaction, including the identity of the parties and the payment information that must appear in the deed.

Buyers accustomed to Canadian or American property transactions should therefore not automatically import the closing mechanics they know from home.

Do You Have to Sign an Arras Contract?

No.

An arras agreement is common but not mandatory.

It is a private preliminary agreement used by many buyers and sellers before the final public deed.

Once signed, however, it can create important legal obligations.

Never treat an arras document as a casual reservation form.

Understand exactly what type of agreement you are signing and what happens if:

• Buyer withdraws
• Seller withdraws
• Mortgage is refused
• Legal problems are discovered
• Completion is delayed
• Deposit has already been paid

Is the Arras Deposit Always 10%?

No universal Spanish law requires every buyer to pay a 10% arras deposit.

The amount is agreed between the parties.

A percentage around 10% is frequently encountered commercially, but the contract determines the actual amount.

You may see:

• Smaller reservation payment
• Deposit paid in stages
• Fixed amount
• Percentage of purchase price
• Different structure negotiated by the parties

Focus on the contract rather than assuming an internet “10% rule” controls every transaction.

Who Should Receive the Deposit?

This depends on the transaction and agreement.

A deposit might be paid to:

• Seller
• Authorized intermediary
• Lawyer/client account where properly arranged
• Another account specified under the agreed structure

Do not assume that every payment to an estate agency is automatically unsafe.

But do not send a large deposit merely because an agent sends an IBAN by WhatsApp.

Before transferring funds, verify:

• Who owns the receiving account?
• Why is that person or company receiving the money?
• Does the contract authorize it?
• Who ultimately owns the deposit?
• Under what conditions can it be refunded?
• What happens if the sale does not complete?
• Is the account information independently verified?

For substantial deposits, independent legal review before payment is highly advisable.

Never Trust a Changed IBAN Without Verification

Property transactions are attractive targets for payment-redirection fraud because the amounts are large and buyers expect to receive banking instructions electronically.

Suppose you receive:

“Our seller has changed banks. Please use this new IBAN.”

Do not transfer hundreds of thousands of euros based solely on that email.

Confirm payment instructions through a separately verified communication channel.

This is especially important if:

• Account details suddenly change
• Beneficiary name changes
• Country changes
• Payment becomes urgent
• Someone asks you to bypass the lawyer
• Email language looks unusual

Once an authorized bank transfer is executed, reversing it can be extremely difficult.

Why Source of Funds Matters Before the Property Purchase

One of the biggest banking problems for foreign buyers occurs before any draft or transfer is issued.

The money reaches Spain—and the bank asks where it came from.

Spanish financial institutions must perform customer due diligence and anti-money-laundering checks.

A buyer moving €400,000, €800,000 or €2 million into Spain should expect the possibility of source-of-funds questions.

Your bank may want documentation showing that the money came from:

• Employment savings
• Property sale
• Business sale
• Investments
• Inheritance
• Gift
• Pension assets
• Company distribution
• Other legitimate wealth

For a detailed explanation, see bringing cash and transferring money to Spain.

Do Not Transfer Property Money to Spain at the Last Minute

Consider this scenario.

Six Months Before Completion

Buyer has €500,000 in a Canadian investment account.

Two Days Before Completion

Buyer sells investments and sends €500,000 to a newly opened Spanish account.

Bank Response

The transaction is selected for compliance review and the bank asks for:

• Investment statements
• Tax return
• Evidence of original wealth
• Sale records
• Proof of tax residence
• Explanation of property purchase

Completion Day

Money remains under review.

The problem is not that the buyer lacks the money.

The problem is timing.

Start the banking process early.

Build a Source-of-Funds File Before You Need It

A strong file might contain:

• Passport
• NIE
• Tax identification details
• Foreign tax returns
• Employment documentation
• Bank statements
• Brokerage statements
• Property-sale documentation
• Inheritance papers
• Company financial documents
• Transfer records

The exact documentation depends on the source.

A €600,000 property-sale receipt should have a different evidence trail from €600,000 accumulated through employment and investments.

Is Moving Your Existing Savings to Spain Taxable?

Transferring money and generating taxable income are not the same event.

If you move your existing money from an account abroad into your own Spanish account, the fact that the transfer is large does not by itself define the tax treatment.

What matters is what the funds represent.

For example:

• Existing savings
• Salary
• Capital gain
• Property-sale proceeds
• Gift
• Inheritance
• Dividend
• Business income

These categories can have different tax consequences.

A bank’s request for proof of funds is also different from the Tax Agency determining whether tax is due.

What If Your Money Is in Dollars, Pounds or Canadian Dollars?

Currency conversion can materially affect the final cost of the property.

Imagine a €600,000 purchase.

A small difference in the EUR/CAD, EUR/USD or EUR/GBP conversion rate can be worth thousands of euros.

Compare:

• Exchange rate
• FX spread
• Transfer charge
• Intermediary-bank charges
• Receiving fees
• Timing
• Whether the rate can be fixed in advance

Do not evaluate a currency provider only by looking at a “€0 transfer fee.”

The exchange-rate spread can matter much more.

Can You Use Wise or Another Payment Provider?

Regulated payment and currency providers can be useful for international transfers and currency conversion.

But a property completion is not an ordinary €500 transfer.

Before relying on any provider for the final purchase price, verify:

• Transaction limit
• Settlement timing
• Beneficiary requirements
• Source-of-funds process
• Whether the notary and seller agree with the payment structure
• Whether funds will definitely be available when required

Use the payment provider as part of a coordinated transaction—not as a last-minute workaround.

Can You Pay Directly From a Foreign EU Bank Account?

Potentially, yes.

For euro accounts within SEPA, cross-border payments are specifically designed to function across national borders.

A German, French, Dutch or Belgian IBAN is not inherently invalid merely because the property is located in Spain.

However, there is an important difference between:

legal ability

and

practical convenience.

A Spanish account can still make it easier to obtain a local bank draft, communicate with a branch, organize mortgage payments and manage ongoing Spanish expenses.

What Is IBAN Discrimination?

Within the applicable SEPA framework, a payer or payee generally should not be rejected merely because their eligible payment account is located in another EU Member State.

For example, a service provider that accepts SEPA direct debit should not simply insist:

“We accept only ES IBANs.”

That can constitute IBAN discrimination.

Foreign property owners sometimes encounter legacy systems or administrative processes that make non-Spanish accounts inconvenient in practice.

If that occurs, understand that inconvenience does not necessarily mean the Spanish account is legally required.

Why a Spanish Account Can Still Make Life Easier

After the property purchase, owners often need to manage:

• Electricity
• Water
• Gas
• Internet
• Community fees
• Insurance
• Mortgage
• Local taxes
• Maintenance services
• Alarm systems

Many of these expenses can be handled through direct debit.

A Spanish account can simplify administration, particularly for a foreign owner who spends part of the year outside Spain.

This is one reason opening the account can make sense even when the account was not legally necessary to acquire title.

Do Foreign Buyers Need an NIE?

Foreign buyers normally need a Spanish NIE for the tax and administrative aspects of a property transaction.

The NIE identifies a foreigner in dealings with Spanish authorities and many private institutions.

It does not provide:

• Spanish residence
• Work rights
• Citizenship

It is an identification number.

If you have not yet arranged yours, see our NIE Number in Spain guide.

Does Buying Property Give You Spanish Residence?

No.

Property ownership and immigration status are separate.

Buying:

• An apartment
• Villa
• Commercial property
• Land

does not by itself give a foreign buyer the right to reside permanently in Spain.

Spain’s former investment-based Golden Visa route is no longer available for new property-based applications.

A buyer who intends to live in Spain must independently determine which immigration route applies.

This distinction should be understood before committing substantial funds to a property.

What If You Need a Spanish Mortgage?

Then the banking process becomes even more integrated with the purchase.

A Spanish mortgage lender may need to review:

• Foreign income
• Employment
• Tax returns
• Existing debts
• Credit profile
• Property valuation
• Deposit
• Source of funds
• Residency status

For foreign borrowers, documentation usually becomes as important as income itself.

See our guide to mortgages for foreigners in Spain.

Mortgage Buyers Have Additional Timing Rules

Where a residential mortgage falls under Spain’s mortgage-credit legislation, there are additional pre-contractual steps before the loan can be signed.

Do not treat mortgage approval and property completion as one last-minute appointment.

The lender, notary, buyer and seller must all be operating on compatible schedules.

This makes early preparation particularly important for non-resident buyers.

What Can Cause a Property Completion to Fail at the Last Minute?

Banking is only one possible cause.

Problems can include:

• Funds not arriving
• Bank compliance hold
• Incorrect bank draft
• Beneficiary mistake
• Missing NIE
• Power-of-attorney problem
• Mortgage issue
• Property charge
• Registry issue
• Seller documentation
• Unresolved debt
• Contractual disagreement

We cover this broader risk separately in why a Spanish property purchase can collapse before the notary signing.

This page should remain focused on banking and payment mechanics rather than duplicating the entire property-completion guide.

Common Banking Mistakes Foreign Property Buyers Make

Assuming a Spanish Bank Account Is Legally Mandatory

It is often convenient, but that is different from being universally required.

Assuming Bank Drafts Are the Only Valid Payment Method

Transfers can also be used.

Sending the Full Purchase Price Too Early

This can expose the buyer unnecessarily.

Trying to Transfer Everything on Completion Morning

A banking problem can leave the transaction without usable funds.

Ignoring Source-of-Funds Checks

Having money does not mean the bank must process it without due diligence.

Opening a Spanish Account at the Last Minute

A large incoming transfer shortly after account opening can trigger additional questions.

Assuming Arras Must Be 10%

There is no universal statutory 10% rule.

Signing Arras Without Legal Review

A preliminary agreement can create binding obligations.

Paying an IBAN Received Only by Email

Verify account details independently.

Assuming Instant Means Unlimited for Your Account

Payment infrastructure and your bank’s personal transaction limits are different things.

Forgetting the Seller’s Mortgage

The payment structure may have to deal with an existing secured debt.

Ignoring Currency Risk

Exchange-rate movement can materially change your purchasing power.

Keeping No Payment Records

Property transactions need a clear financial trail.

Frequently Asked Questions

Do I need a Spanish bank account to buy property in Spain?

No universal rule requires every foreign buyer to hold a Spanish bank account. However, a local account can simplify payment, mortgages, taxes, utilities and ongoing property administration.

Do I need a bank draft to buy a house in Spain?

No. Bank drafts are common, but appropriately arranged bank transfers are also used.

What is a cheque bancario?

It is a bank-issued cheque or draft for which the issuing bank secures the relevant funds, providing the seller with greater payment certainty than an ordinary personal cheque.

Can I pay for Spanish property using a transfer?

Yes. Bank transfers can be used and the payment information is reflected in the notarial documentation.

What is a TARGET transfer?

It is a bank-to-bank euro payment mechanism useful for high-value same-day payments when processed within the applicable bank timetable.

Is TARGET the same as OMF?

You may still hear the older term OMF in Spain. TARGET is the terminology increasingly used for the current euro high-value transfer infrastructure.

Can I use an instant transfer for €300,000?

The previous €100,000 system limit has been removed, making high-value instant transfers technically possible. Your bank can nevertheless apply its own limits and security controls.

Is a 10% arras deposit compulsory?

No. An arras contract itself is not mandatory, and there is no universal law requiring every deposit to equal exactly 10% of the purchase price.

Should I pay arras directly to the seller?

That depends on the contract. Before paying anyone, verify the recipient, legal basis for the payment and refund conditions.

Can an estate agent hold my deposit?

Depending on the contractual arrangement, an intermediary may receive funds. Do not transfer substantial money without understanding who owns the receiving account, why the agent is receiving it and what happens if the transaction fails.

Can I use my German or French bank account for a Spanish property?

Potentially, yes. A foreign EU IBAN is not inherently invalid for a Spanish transaction. The final payment structure should nevertheless be agreed in advance.

Can Spanish utilities insist on a Spanish IBAN?

Within the applicable SEPA framework, refusing an eligible EU account solely because its IBAN is from another Member State can amount to IBAN discrimination.

Should I transfer all my money to Spain before buying?

Not necessarily. Transfer timing should reflect banking compliance, currency risk and the agreed completion mechanics.

Will the Spanish bank ask where my money came from?

It can. Large or unusual transactions can require source-of-funds documentation.

Does transferring my savings to Spain create tax?

The transfer itself does not by itself determine whether tax is due. The nature and origin of the underlying funds matter.

Can I pay for a Spanish property from Canada?

Yes, subject to the banking and transaction arrangements. For a large cross-border purchase, prepare source-of-funds documentation and payment timing well in advance.

Can I pay from a US bank?

Potentially, but direct non-euro international transfers create additional currency, timing and settlement considerations. Many buyers convert and position the funds before completion.

Can I buy property without being a Spanish resident?

Yes. Foreign non-residents can generally purchase property in Spain. Property ownership and Spanish immigration residence are separate matters.

Does buying property give me a visa?

No. Purchasing Spanish property no longer creates a new property-investment Golden Visa route.

What happens if my transfer is delayed on completion day?

The parties may have to postpone completion or agree another solution. The consequences depend on the transaction and contracts, which is why payment mechanics should be arranged in advance.

How Newcomer.es Can Help

Foreign buyers frequently need to coordinate several Spanish systems simultaneously:

NIE → bank account → source of funds → property search → mortgage → notary → utilities

Newcomer.es can assist with the relocation and administrative parts of that process, including:

• NIE applications
• Opening a Spanish bank account
• Moving money to Spain
• Spanish property guidance
• Mortgages for foreigners
• Relocation administration
• Property-owner support
• Utility coordination

Where individualized conveyancing, tax, mortgage or legal advice is required, the appropriate qualified professional should handle that part of the transaction.

If you are preparing to buy property and want help coordinating the practical stages, contact Newcomer.es.

The Bottom Line

A Spanish bank account can make buying and owning property in Spain easier.

A banker’s draft can make completion simple and secure.

But neither should be presented as the only legal way to complete a Spanish property transaction.

In 2026, foreign buyers have several realistic payment options:

Banker’s draft

TARGET transfer

Instant transfer

Properly documented advance transfer

The key is not choosing the supposedly “Spanish” method.

It is making sure the payment method is agreed, traceable, bank-approved and ready before everyone sits down at the notary.

For an international buyer, the safest approach is therefore:

prepare the NIE → establish banking early → document the source of funds → verify every IBAN → agree the completion method → move the money with enough time → sign only when the financial structure is ready.

That is what turns a high-value cross-border property purchase from a banking gamble into a controlled transaction.
