Deposit Agreement in Madrid: What You Should Know Before Buying or Selling Property






If you are about to buy a home in Madrid or sell a property, the deposit agreement (contrato de arras) is usually the most important step before signing at the notary. It is the document that “locks in” the transaction: it sets the price, deadlines and conditions, and determines what happens if either party fails to comply.

The deposit agreement is a private contract between buyer and seller whereby both parties commit to completing the purchase within a specified timeframe. Typically, the buyer pays a deposit and the essential terms are agreed upon: price, signing date, property condition and documentation.


Types of deposit agreements: the difference you should know

  • Penitential deposit: allows withdrawal; the buyer loses the deposit and the seller must return double.
  • Confirmatory deposit: reinforces commitment and allows enforcement or damages.
  • Penalty deposit: includes a contractual penalty in case of breach.

If the type of deposit is not clearly specified, it is advisable not to sign.


How much is usually paid

Typically around 10% of the purchase price, although it may vary. The agreement should clearly specify the amount, payment method and allocation to the total price.
