Buying off plan in Spain
Quick answer
Off plan means paying before the home exists. The law requires advance payments to be secured by a guarantee and held in a separate account, and the registrars advise checking the developer, the land and the licence first. Treat the contract and the guarantee as the product you are buying.
Applies toBuyers considering a home that has not been built or finished. Completed new builds are covered on the new-build page.

§ 1What off plan means
Buying off plan means signing and paying while the home is still a plan or a building site. You pay in stages as the work advances, and you receive the home at the end. The attraction is a lower entry price and the chance to choose finishes. The cost is that you carry the risk of delay, change and failure before you have anything to inspect.
§ 2The legal protections
Spanish building law requires a developer who collects advance payments from buyers to guarantee their refund and to hold the money in a separate account used for that purpose. The ten-year structural guarantee also applies to the finished building. These protections are the reason off-plan buying is workable, but they depend on being in place, so ask for evidence of the guarantee and the account before you pay, not after.
§ 3Checks before you pay
The registrars advise checking, before paying any deposit, the developer's registration, its ownership of the land and the building licence. Ask for the plans and the specification and compare them with what the sales office showed you. Ask who holds the guarantee and whether it covers each payment. Read the clause on delay, since a completion date without a consequence is only a hope.
§ 4How to pay
Notaries prefer payment by bank transfer or nominative cheque. Pay each stage into the account named in the contract and keep the receipt. If a reservation uses arras, read which kind it is: confirmatory is the most common, and penitential applies only if agreed and changes the cost of withdrawing.
§ 5Typical problems
Delays are the commonest problem. Others include changes to the specification, a building that differs from the sales brochure and a developer that runs out of money. Each is easier to handle if the contract says what you can do. Ask your lawyer which clauses give you a right to cancel and to a refund, and which do not.
§ 6Where to read next
The refund guarantee is the heart of the matter, and protection for advance payments explains how it works. The risk of a developer that cannot finish is covered in the risk of an unfinished building.
For the end of the process, the handover inspection shows what to check when you receive the home, and the ten-year guarantee explains the long-term cover.
Completed new homes are covered in new homes from a developer, and what a resale involves describes the alternative.
Groups of buyers sometimes build together, which joining a housing cooperative explains, and the main comparison is on whether to buy new or used.
§ 7A rule of thumb
The more you pay before you see the home, the more you should have checked. A small, refundable reservation against a full contract is one thing. Large instalments against a promise are another. Let your lawyer see the contract, the guarantee and the account details before the first instalment, and do not be hurried by a limited offer.
FAQRelated questions
Is buying off plan riskier than buying a finished home?
Yes, because you pay before you can inspect, and the risk is the building not being finished or finished differently. The law gives protections, but they work only if the guarantee is in place and you hold the paperwork. Verify them before you pay.
Should I pay the reservation deposit before seeing the contract?
No. Ask for the full contract, the plans and the specification first and have your lawyer read them. A small reservation can be reasonable, but only against a document that sets out what is reserved and what happens to the money.
What happens to my money if the building is not built?
The law requires advance payments to be covered by a guarantee, so that they can be refunded, and held in a separate account. Your remedy depends on that guarantee existing, so ask for a copy and keep it with the contract.
