Having a Spanish property purchase fall through is stressful, expensive, and more common than most buyers expect. Whether the seller receives a higher offer, your mortgage is declined, or a legal issue surfaces during due diligence, understanding your rights and obligations at each stage can save you thousands of euros and months of uncertainty.
This guide explains the legal framework around failed property purchases in Spain, with a focus on the arras contract — the document that defines what happens when a deal collapses. For the full purchase process from start to finish, see our step-by-step buying guide.
The Stages of a Spanish Property Purchase
To understand what happens when a purchase fails, you first need to know where you are in the process. A Spanish property purchase has three key stages, and your exposure increases at each one:
Stage 1: Before the Arras Contract
At this stage, you may have made a verbal offer or signed a non-binding reservation agreement (sometimes with a small holding deposit of EUR 3,000-6,000). Legally, neither party is committed:
- Buyer pulls out: You should receive your reservation deposit back in full, though some agents attempt to retain it. If the reservation document says "non-refundable", it may be enforceable — always have your lawyer review before signing anything
- Seller pulls out: They return the reservation deposit. You have no claim for damages or compensation at this stage
- Risk level: Low — typically only the reservation deposit (if any) is at stake
Stage 2: After Signing the Arras Contract
The arras contract (contrato de arras) is the critical document. This is where real money — typically 10% of the purchase price — changes hands, and both parties take on binding obligations. What happens when either party withdraws depends entirely on which type of arras you signed (see below).
Stage 3: After the Escritura (Completion)
Once the escritura pública (public deed of sale) is signed at the notary and registered at the Land Registry, the sale is complete. Unwinding a completed sale is extremely difficult and only possible in cases of fraud, material misrepresentation, or hidden defects that amount to vicios ocultos (hidden vices). This is a court matter and typically takes 1-3 years.
The Three Types of Arras Contract
Spanish law recognises three types of arras agreement, and the type you sign determines your rights and losses if the purchase fails. This is the single most important legal distinction in any Spanish property transaction:
1. Arras Penitenciales (Penalty Arras)
This is the most common type used in residential transactions and the one most UK buyers will encounter. It gives both parties the right to walk away, but at a cost:

- If the buyer withdraws: The buyer loses the entire deposit. If you paid EUR 35,000 on a EUR 350,000 property, you forfeit EUR 35,000
- If the seller withdraws: The seller must return double the deposit. The seller would pay you EUR 70,000 (your original EUR 35,000 plus an additional EUR 35,000 as penalty)
- No further claims: Neither party can pursue additional damages beyond the deposit penalty. This is both the advantage and disadvantage — it provides a clean exit but limits your compensation
- Legal basis: Article 1454 of the Spanish Civil Code
This type of arras is popular because it provides certainty for both parties. You know your maximum downside before you sign.
2. Arras Confirmatorias (Confirmatory Arras)
These are binding and do not give either party the right to withdraw by simply paying a penalty:
- If the buyer withdraws: The seller can sue for specific performance (forcing the buyer to complete the purchase) or sue for damages that exceed the deposit amount
- If the seller withdraws: The buyer can sue to force the sale to complete, or claim damages including deposit return, legal costs, survey fees, mortgage arrangement costs, travel expenses, and any loss from having sold another property in reliance on the purchase
- Higher risk, higher protection: Both parties face greater consequences for withdrawing, which makes the transaction more secure but less flexible
Arras confirmatorias are less common in standard residential sales but may be used for high-value properties or when either party wants maximum security.
3. Arras Penales (Penal Arras)
A hybrid approach where the arras acts as a fixed penalty for breach, but the other party can also pursue additional damages:
- If the buyer withdraws: The buyer loses the deposit AND the seller can claim further damages if they can prove additional losses
- If the seller withdraws: The seller returns double the deposit AND the buyer can claim further damages
- Rarely used: This type is uncommon in practice because it combines the worst aspects for both parties. Most lawyers will steer you towards penitenciales or confirmatorias
Common Scenarios: What Actually Happens
Scenario 1: The Seller Gets a Higher Offer
This is the most common reason for seller withdrawal, particularly in a rising market. A seller who signed arras penitenciales with you for EUR 350,000 receives an offer for EUR 400,000. The maths is simple: return your EUR 35,000 deposit plus pay a EUR 35,000 penalty (EUR 70,000 total), but gain EUR 50,000 on the sale price. The seller is EUR 15,000 better off by breaking the contract.
Your options:
- Accept the double deposit return and move on
- If you suspect the arras should be interpreted as confirmatorias (which depends on exact wording), engage a lawyer to argue for specific performance or higher damages
- Negotiate — sometimes sellers will offer a compromise price to keep the deal together rather than risk the new buyer also pulling out
Scenario 2: Your Mortgage Is Declined
Spanish mortgage approvals are not as predictable as UK ones. If your mortgage is declined after signing the arras, you face losing your deposit under arras penitenciales unless:
- Your arras contains a mortgage clause (cláusula suspensiva): This makes the contract conditional on mortgage approval. If the mortgage is declined, the contract is voided and your deposit returned. Always insist your lawyer includes this clause if you are financing
- You can complete without a mortgage: If you have the funds to buy outright, the mortgage refusal does not affect the purchase
- You find alternative financing: Another lender may approve the mortgage within the arras timeframe (typically 60-90 days)
Scenario 3: Legal Issues Discovered During Due Diligence
Your lawyer's searches reveal a problem — an illegal extension, missing licences, planning violations, unpaid community fees, debts registered against the property, or a boundary dispute. Your position depends on when the issue was discovered and what the arras says:
- Before signing arras: Walk away with no penalty. This is why your lawyer should conduct due diligence before you sign the arras, not after
- After signing arras: If the seller warranted a clean title and this proves false, you have grounds to void the contract and recover your deposit (the seller is in breach). If the arras did not contain title warranties, your position is weaker and you may need to negotiate
- Best practice: Always ensure the arras includes a clause making the contract conditional on satisfactory legal due diligence, with a defined period (typically 15-30 days) for your lawyer to complete checks
Scenario 4: Buyer Simply Changes Their Mind
You signed the arras, paid the deposit, but have now decided you do not want the property — perhaps you have found somewhere better, your circumstances have changed, or you have had second thoughts. Under arras penitenciales, you lose the deposit. There is no negotiation, no appeal, and no way around it. The deposit is the price of your change of mind.
Protecting Yourself: Practical Steps
Before Signing Anything
- Instruct a Spanish property lawyer who is independent of the estate agent and seller. Never use a lawyer recommended by the seller's side. For a full guide on costs, see our costs and taxes overview
- Complete key due diligence before the arras: nota simple (land registry extract), catastro (property registry) check, town hall search for planning issues, community of owners debts check, and utilities debts check
- Understand which type of arras you are signing. Ask your lawyer to explain the specific consequences if either party withdraws. If the document does not specify the type, Spanish courts tend to interpret it as arras confirmatorias — which may not be what you want
In the Arras Contract
- Mortgage condition (cláusula suspensiva): Essential if you are financing. Specify the mortgage amount, lender, and deadline for approval
- Due diligence condition: Allow 15-30 days for your lawyer to complete searches after signing, with the right to withdraw and receive a full deposit refund if issues are found
- Deposit in escrow: Have your deposit held by your lawyer or a neutral third party — not paid directly to the seller. Recovery is far easier if the funds are in a controlled account
- Completion deadline: A clear date for signing the escritura, with provisions for extension if both parties agree
- Inventory of included items: Specify what is included (furniture, appliances, fixtures) to avoid disputes at completion
After Signing the Arras
- Move quickly on mortgage applications if financing. Submit all documents to your lender immediately — do not wait
- Stay in contact with your lawyer and respond to requests promptly. Delays on your side can give the seller grounds to claim you are not performing your obligations
- Keep records of all expenditure related to the purchase (legal fees, survey costs, travel, mortgage arrangement fees). If the seller breaches, these form part of your damages claim
Recovering Your Deposit: The Practical Reality
If the seller breaches the arras and owes you money (double deposit under arras penitenciales), the recovery process depends on cooperation:
- Cooperative seller: Your lawyer sends a formal demand (burofax), the seller's lawyer agrees, and funds are transferred within 2-4 weeks
- Uncooperative seller: Your lawyer files a claim in the juzgado de primera instancia (first instance court). A straightforward deposit recovery claim typically takes 6-12 months. If the seller contests the claim, it can extend to 12-24 months
- Escrow advantage: If the deposit was held in your lawyer's escrow account, they can return it to you immediately when the seller breaches. No court action needed to recover the funds — though you may still need to pursue the penalty portion
Key Takeaways
- The arras contract is the most important document in your purchase. Invest time and legal fees in getting it right
- Always include mortgage and due diligence conditions if you are financing or have not completed full legal searches
- Hold the deposit in escrow — never pay it directly to the seller
- Complete as much due diligence as possible before signing the arras, not after. The more you know before you commit, the less likely the purchase is to fall through
- Understand your arras type. If in doubt, arras penitenciales give you a cleaner exit at a known cost
