The arras contract is the point in a Spanish purchase where intention becomes a binding commitment with money at stake. It is also where foreign buyers make their most costly mistakes — signing before due diligence is complete, or accepting terms that quietly shift risk onto them.
What arras is
The contrato de arras is a deposit agreement — typically around 10% of the price — that commits both buyer and seller to complete the sale. The most common form, arras penitenciales, allows either party to withdraw: the buyer forfeits the deposit, or the seller repays double. Either way, once you sign, walking away has a price.
Why buyers sign too early
Pressure. Agents push for a fast signature to secure the deal, and buyers worried about losing the property comply before the paperwork is checked. But the arras is precisely the wrong moment to be uninformed, because it converts uncertainty into financial commitment.
Missing documents before arras
- Nota simple confirming ownership and that charges are clear.
- Cédula de habitabilidad — valid and matching the property.
- Community debt certificate and recent minutes.
- Cadastre and registry agreement on surface and description.
Escrow / account structure risk
A frequent red flag is the agency proposing that the deposit be paid into its own account rather than a neutral or seller-controlled structure. That arrangement can expose the buyer if anything goes wrong. The deposit logic should be understood and, where needed, restructured before you transfer a cent.
Fee and agency pressure
Agency fees and the speed of signing are often used to push buyers into commitment. Reasonable fees and a reasonable timeline are negotiable; urgency is not a reason to skip review. A buyer-side adviser can challenge both without emotion.
Clauses to challenge
- Conditions protecting you if a missing cédula or document is not resolved.
- Clear deadlines and penalty terms that are balanced between the parties.
- Accurate property description, annexes, and included elements.
- Deposit-handling terms that do not place your money at unnecessary risk.
The rule is simple: complete your due diligence, or write protective conditions into the arras, before you sign. After signing, your leverage — and often your deposit — is gone.
