Every year, hundreds of international buyers complete property purchases in Spain — on the Costa del Sol, in Málaga, in the Balearics — and discover problems afterwards that a lawyer would have caught beforehand. Outstanding debts they now owe. Illegal extensions they cannot regularise. Deposits lost to poorly drafted contracts. Tax fines they didn't know were coming.
This guide explains what a real estate lawyer actually does for a buyer in Spain, why you need one who works exclusively for you, and what happens when people try to manage without.
Is a Lawyer Required by Spanish Law to Buy Property?
Technically, no. Spanish law does not require buyers to be represented by a lawyer. The notary oversees the transaction and gives it legal force — but the notary works for neither buyer nor seller. Their role is to certify, not to advise.
In practice, proceeding without independent legal representation is a serious risk. The notary will not investigate the property's background, check for outstanding debts, verify planning status or advise you on contract terms. That is a lawyer's job.
What Does a Real Estate Lawyer Actually Do?
1. Carries Out Due Diligence Before You Commit
Before you sign any contract or pay any deposit, your lawyer investigates the property thoroughly:
- Verifies legal ownership at the Land Registry (Registro de la Propiedad)
- Checks for outstanding mortgages, liens or encumbrances registered against the property
- Requests a certificate of zero debt from the community of owners (comunidad de propietarios)
- Confirms the property is up to date with local council rates (IBI) and other municipal taxes
- Verifies planning status, building licences and whether all structures are legally registered
- Checks the property's energy performance certificate and habitability licence
In Spain, certain debts on a property transfer legally to the new owner at the point of sale. Without due diligence, you inherit them.
2. Reviews and Negotiates the Purchase Contract
Most property purchases in Spain involve two main contracts before the final notarial deed: a reservation contract (contrato de reserva) and a private purchase agreement (contrato de arras).
The arras contract is the most critical. It determines the conditions under which either party can withdraw — and the financial consequences of doing so. Under a standard arras penitenciales agreement, if the buyer withdraws they lose the deposit; if the seller withdraws they return double. But the contract must be correctly drafted for these protections to apply.
A lawyer reviews every clause, ensures the agreed price and conditions are accurately reflected, inserts mortgage and due diligence conditions where relevant, and negotiates terms that protect your position if problems emerge.

Buying property in Spain as a non-resident involves a significant amount of administrative work:
- Obtaining your NIE number (mandatory for any official act in Spain)
- Opening a Spanish bank account
- Setting up direct debits for utilities and community fees
- Applying for residency certificates if relevant
- Registering the property in your name at the Land Registry after completion
Your lawyer manages this process and ensures nothing is missed.
4. Manages Taxes and Filings at Completion
Buying property in Spain triggers tax obligations that must be fulfilled within strict deadlines. If you miss them, you face surcharges and interest.
- Resale properties: ITP (Property Transfer Tax) — 7% in Andalucía — must be filed within 30 working days of completion
- New builds: VAT (10%) and Stamp Duty (AJD, 1.2% in Andalucía)
- Post-sale: change of ownership for IBI, notification to the community of owners, utility transfers
Your lawyer files every declaration on time and handles all communications with the tax authority.
5. Attends the Notary — Or Acts by Power of Attorney
The final deed is signed before a notary. Your lawyer attends alongside you to ensure everything in the deed matches what was agreed, no clauses have been altered, and you fully understand what you are signing.
If you cannot attend in person — which is common for international buyers — your lawyer can act by power of attorney, signing on your behalf and completing the purchase without you needing to travel.
"The Agency Said Their Lawyer Would Handle Everything"
This is one of the most common — and most dangerous — situations international buyers find themselves in.
An agency lawyer works for the agency. Their interest is in the transaction completing. An independent buyer's lawyer works exclusively for you. Their interest is in protecting your money and ensuring you buy safely.
This is not a minor distinction. A lawyer with a conflict of interest — however well-intentioned — cannot fully represent your interests.
What Does Legal Representation Cost?
A real estate lawyer's fee in Spain is typically 1% of the purchase price, with a minimum fee depending on the complexity of the transaction. On a €300,000 property, you are looking at approximately €3,000.
Compare this to the cost of inheriting an undisclosed €15,000 community debt, losing a €30,000 deposit due to a poorly drafted contract, or facing a €25,000 tax penalty for late filing. Legal fees are not an optional extra. They are the cheapest insurance you will buy.
