The riskiest moment in a Barcelona sale is not always the notary signing. It is often the week before the deposit contract, when everyone is happy, the price feels agreed, and the pressure is to “just sign the arras”.
That is exactly when small wording becomes expensive.
In Catalonia, the deposit contract is not just a receipt. It can decide who keeps the deposit, whether the buyer can withdraw if the bank refuses financing, who pays pending community debts, what happens if a document is missing, and when the buyer actually receives possession.
This article is a practical checklist for homeowners, sellers and serious buyers before signing a Barcelona contrato de arras. It is not legal advice. For legal wording, tax effects or a dispute, use a lawyer, notary or qualified advisor. But before you reach that desk, these are the points I would want clearly checked.
Practical rule: do not sign arras because the negotiation feels finished. Sign when the price, deposit, conditions, documents, deadlines and handover are written clearly enough that both sides understand what happens if something goes wrong.
1. Confirm what type of arras you are signing
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
The word “arras” is used too casually. In Catalonia, that can create a real problem.
Under Article 621-8 of the Catalan Civil Code, published in the BOE, money delivered by the buyer is presumed to be confirmatory arras: proof that the sale has been concluded and paid on account of the price. Penitential arras, the familiar formula where the buyer loses the deposit if they withdraw and the seller returns double if they withdraw, must be expressly agreed.
That means the contract should not simply say “the buyer pays EUR 20,000 as arras”. It should say what legal effect those arras have.
| Deposit wording to check | Why it matters |
|---|---|
| Are they confirmatory or penitential? | The consequences of withdrawal are different |
| If penitential, is that stated expressly? | In Catalonia, it should not be left implied |
| Is the deposit paid on account of the price? | The final notary payment must deduct it correctly |
| What happens if the seller withdraws? | Usually double return only if penitential arras are clearly agreed |
| What happens if the buyer withdraws? | The buyer may lose the deposit unless a valid condition applies |
| Is there a financing condition? | This can change the result if the bank refuses the mortgage |
For sellers, vague arras can create a false sense of security. For buyers, vague arras can turn a financing or registry issue into a fight about money. The solution is not dramatic: name the type of arras and write the consequences in plain language.
2. Treat the mortgage clause as a real clause, not a courtesy
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
Many Barcelona buyers need bank financing. Everyone knows this, but many arras contracts still handle it with one weak sentence.
Article 621-49 of the Catalan Civil Code deals with purchases where the contract foresees financing by a credit institution. In broad terms, if the agreed financing is refused and the buyer justifies it within the agreed period, the buyer may withdraw and recover amounts paid, including penitential arras, unless the contract says otherwise or the refusal is due to buyer negligence.
The practical point: do not leave the financing clause half-written.
| Financing point | What to write clearly |
|---|---|
| Is the purchase subject to mortgage approval? | Yes or no, not implied |
| How much financing is needed? | Amount or percentage of price |
| Which bank or type of lender is relevant? | Named bank if already chosen, or credit institution wording |
| What proof is needed if refused? | Written denial from the bank |
| What is the deadline to prove refusal? | A specific date, not “soon” |
| What happens to the deposit? | Refund, retention or other agreed result |
| What counts as buyer negligence? | Missing documents, late application or unrealistic request can become disputed |
This matters for both sides. A seller does not want the apartment blocked for weeks by a buyer who has not even submitted a serious mortgage file. A buyer does not want to lose the deposit because the contract ignored the financing reality.
If you are buying with financing, prepare the file before signing. This mortgage documentation guide may help: Mortgage Approval Requirements in Spain 2026.
Avoid the dangerous middle ground: “The buyer will request a mortgage” is not enough. If the sale depends on financing, the arras should say what amount is needed, by when, how refusal is proved and what happens to the deposit.
3. Read the nota simple before the deposit moves
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
The nota simple is the first document I want on the table before serious arras. Not after. Before.
It shows the registered owner, property description and registered charges. It may reveal a mortgage, embargo, usufruct, use right, condition, limitation, discrepancy in ownership or a parking/storage registration issue. Sometimes everything is clean. Perfect. But you want to know that before the buyer transfers the deposit.
Checklist:
- The seller in the arras matches the registered owner.
- All co-owners are identified and will sign or authorize properly.
- The property description matches what is being sold.
- Parking spaces or storage rooms are correctly included or excluded.
- Existing mortgages are identified.
- Embargoes, liens, rights of use or limitations are understood.
- The cadastral address and the address used in the sale are coherent with the documents.
For sellers, this is where preparation pays off. If there is an old mortgage already paid but not cancelled at the Registry, plan the cancellation before promising a clean signing date. If an inheritance is pending registration, do not pretend it is a normal sale. If one spouse, heir or co-owner has not agreed, the arras should not run ahead of the ownership reality.

4. Decide who holds the deposit
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
The deposit should not float in ambiguity. Before signing, everyone should know where the money goes and under what conditions it is released.
Common options include:
| Deposit holder | Practical notes |
|---|---|
| Seller | Simple, but buyer may feel exposed if documents are still pending |
| Real estate agency | Common in practice; the contract should state the role and release rules |
| Notary deposit | More formal; especially useful for certain penitential arras structures |
| Lawyer or escrow-style client account | Useful in more complex transactions, depending on professional setup |
Article 621-8 also contemplates penitential arras deposited before a notary for a maximum term of six months and recorded at the Land Registry under certain conditions. This is not used in every ordinary transaction, but it shows the point: where the money sits can matter.
Ask:
- Who receives the deposit?
- In which account?
- Is it held as stakeholder or paid directly to the seller?
- When is it released?
- What document triggers refund or retention?
- What happens if completion is delayed but not cancelled?
- Who pays bank transfer fees or administrative costs, if any?
A serious buyer can accept a meaningful deposit. A serious seller can accept clear custody rules. Neither side benefits from a deposit arrangement that depends on memory.
5. Put the deadlines in calendar language
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
A weak arras contract says: “The sale will be signed before a notary within approximately two months.”
A stronger contract says: “The public deed of sale will be signed no later than 30 September 2026, unless the parties agree in writing to extend the deadline because of a documented mortgage, registry or notarial issue.”
The contract should distinguish several dates:
| Date | Why it matters |
|---|---|
| Deposit payment date | Confirms when the buyer’s commitment starts |
| Deadline for mortgage approval or refusal | Controls the financing condition |
| Deadline for seller documents | Cédula, energy certificate, community certificate, mortgage cancellation data |
| Notary signing deadline | Main completion date |
| Possession date | May be same day as notary, or later if agreed |
| Furniture/removal date | Avoids arguments over emptying the apartment |
| Utility handover date | Helps avoid unpaid bills and access problems |
Possession deserves its own line. In a vacant apartment, keys are usually handed over at notary after payment. In a rented, inherited, occupied or post-divorce property, possession may require more detail.
If the home is rented, read the arras together with the lease reality. This guide goes deeper into that scenario: How to Sell a Rented Apartment in Barcelona.
6. List pending documents instead of pretending they exist
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
Many arras are signed before every document is ready. That is normal. What is not normal is hiding it.
For a Barcelona apartment, pay special attention to:
| Document or issue | Why it matters before signing arras |
|---|---|
| Cédula de habitabilidad | Gencat states it is needed to transfer a dwelling by sale, rent or assignment of use, except legal exemptions |
| Energy certificate and label | ICAEN manages the Catalan energy certificate system and register; the label is part of sale/rental information |
| Community debt certificate | Required at public deed unless the buyer expressly waives it |
| Mortgage cancellation certificate or bank figures | Needed when the seller’s mortgage will be cancelled at completion |
| IBI and cadastral reference | Used for identification, tax and practical checks |
| Latest community minutes or special assessments | Reveals pending works, lift, facade, roof or accessibility costs |
| Inheritance, divorce or power of attorney documents | Needed where the seller’s authority or ownership has special facts |
Gencat’s procedure explains that the cédula de habitabilidad is necessary to transfer a dwelling, except in legally allowed cases. ICAEN explains the energy certification system for buildings and provides procedures and certificate lookup tools.
Do not use arras to say “all documents are in order” if they are not. Use arras to say:
- Which document is pending.
- Who must obtain it.
- By what date.
- Whether the buyer can withdraw if it cannot be delivered.
- Whether the seller can extend the deadline.
- Whether any price adjustment applies.
A clean pending-document clause is better than an optimistic silence. Silence feels comfortable on signing day and uncomfortable when the notary appointment has to move.
7. Check community debts and approved building costs
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
For apartments in a building community, the community debt certificate is not decoration.
Under Article 9 of the Horizontal Property Law, the seller must state in the public deed whether they are up to date with community expenses or what they owe, and provide a certificate matching that statement. Without it, the notary cannot authorize the public deed unless the buyer expressly waives the requirement. The same article also makes the acquired property legally affected by certain previous community debts, within legal limits.
Before arras, ask the administrator or seller:
- Are community fees fully paid?
- Are there approved special assessments?
- Are facade, roof, lift, accessibility or structural works approved or expected?
- Has the community discussed restrictions, tourist-use issues or legal claims?
- Who pays any approved assessment: seller, buyer or split by date?
- Will the certificate be available before notary?
This is especially important in older Barcelona buildings. A buyer may accept future works, but they should not discover them after transferring the deposit.
8. Define furniture, fixtures and condition
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
Many arguments after arras are not about law. They are about a lamp, appliance, wardrobe, air-conditioning unit, alarm system, awning, terrace furniture or custom shelving.
Write it down.
| Item | Contract treatment |
|---|---|
| Built-in kitchen appliances | Included or excluded |
| Freestanding appliances | List each one |
| Furniture | Inventory if included |
| Light fixtures and curtains | Clarify removal or inclusion |
| Air conditioning and heating units | Confirm they stay and work, if relevant |
| Alarm, internet or smart devices | Remove, transfer or deactivate |
| Storage room contents | Empty by what date |
| Repairs before completion | Describe specific repair and evidence |
The contract should also say the property is delivered in the condition seen by the buyer, except agreed repairs or removals. If the seller promises to fix a leak, replace a broken blind or clear a storage room, put the promise into the arras with a date.
Photos help. An inventory helps more.
9. Slow down in special cases: inherited, rented or divorce sales
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
Some sales need more care before arras because the property has a legal or practical layer beyond the normal buyer-seller negotiation.
Inherited apartment
Check whether the inheritance has been accepted, taxes filed where needed, and the heirs are registered or able to sign the sale correctly. If several siblings inherit, all relevant owners must agree. For more detail, read Inheriting an Apartment in Barcelona in 2026.
Rented apartment
The arras must reflect whether the buyer receives the apartment vacant or with the tenant inside. If vacant possession is promised, the tenant exit must be real, documented and timed. If the buyer accepts the lease, the lease documents should be reviewed before the deposit.
Divorce or separation
Check ownership, mortgage debt, family-home use rights, court measures and who has authority to sign. A property can be owned by two people, used by one, and financed by both. Those layers must not be mixed casually. This article may help: Selling Your Apartment After Divorce in Barcelona.
In these cases, a standard arras template is often too thin. The contract should match the real story of the apartment.
10. Questions to ask before signing
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
Before anyone signs, I would put these questions on one page and answer them calmly.
| Question | Good answer |
|---|---|
| What type of arras are these? | The contract states it expressly |
| Who owns the property? | Matches the updated nota simple |
| Are there charges? | They are identified and cancellation is planned |
| Is the buyer using financing? | The financing clause is specific |
| Who holds the deposit? | Named person/entity, account and release rules |
| What documents are missing? | Listed with responsible party and deadline |
| Are community debts clear? | Certificate process and approved costs are known |
| What stays in the apartment? | Furniture and fixtures are listed |
| When does possession transfer? | Written date and key handover rule |
| What happens if a condition fails? | Refund, retention, extension or cancellation is written |
| Is this a special case? | Inheritance, divorce, rental or occupation issues are reflected |
The best arras contract is not the longest. It is the one that removes uncertainty where the transaction is actually fragile.
A deposit contract should reduce tension, not create it
Legal frame: Spanish Civil Code, Registradores and Spanish Notaries.
A Barcelona sale has enough moving parts: registry, bank, notary, documents, taxes, community, timing and human pressure. The arras should organize those parts before money changes hands.
For sellers, the goal is to avoid blocking the apartment with a buyer who cannot complete or a contract that promises more than the seller can deliver. For buyers, the goal is to avoid transferring a serious deposit before checking ownership, charges, financing, documents and possession.
Before signing, ask for the nota simple, define the type of arras, write the financing clause properly, clarify who holds the deposit, list pending documents, check community debts, and make the handover concrete.
That is not being difficult. That is treating a serious transaction seriously.
