Contracts before completion when buying in Spain

By Inés Arroyo VidalReviewed by Marta Calderón IbáñezPublished Updated Stage 4: Check and contract

Quick answer

Before the deed you may be asked to sign a reservation, an arras agreement or a private purchase contract, and to pay a deposit. None is compulsory, but each can bind you. Read them with your lawyer, understand what happens to the money if either side withdraws, and do not sign under time pressure.

Applies toBuyers who have been asked to sign something or pay something before the deed.

§ 1The stage between agreement and deed

Between agreeing a price and signing the deed, many sellers and agents ask the buyer to sign a paper and pay money. The names vary: reserva, señal, arras, contrato privado. They are not the same, and the differences decide what you can lose. The notary’s own guidance says arras are optional, and that the most common type is confirmatory arras. The documents form one family, each with a different purpose. It belongs to the process described in the buying-process section of this handbook.

§ 2Reservation

A reservation takes the home off the market for a short time while you do your checks, in return for a small payment. It is usually the first paper. The terms matter more than the name: is the payment refundable, for how long does it hold, and what happens if the checks fail. See the reservation contract.

§ 3Arras

Arras are a payment on account of the price, made under a contract that fixes the terms of the sale. The type decides what happens if someone withdraws. The notary’s page explains that arras are optional, that confirmatory arras are the most common, and that penitential arras apply only if agreed, with loss of the deposit by the buyer or return of double by the seller. The detail is in arras.

§ 4The private contract

A private purchase contract sets out the terms: the price, what is sold, the deadline for the deed, the conditions and the penalties. It is usually signed with a deposit. It binds the parties, and sometimes forces a sale. Read it carefully. The content is in the private purchase contract.

§ 5The deposit

Whatever the paper is called, the money you pay raises questions of who holds it, what it counts for and when you get it back. Those are covered in the deposit.

§ 6Pulling out

Sometimes a buyer needs to withdraw. What it costs depends on what you signed. Pulling out explains the cases, and how to prepare so that a withdrawal is possible.

§ 7Fees and taxes on the papers

Signing a private contract does not usually trigger the main purchase taxes, which arise on the deed, but fees for the lawyer’s review and for any translation are payable early. Ask for them in the quote, so that the cost of getting to the deed is clear.

§ 8Why the order matters

Most disputes about contracts before the deed come from sequence. A buyer pays, signs and only then checks. By that time the seller holds the money and the paper, and the buyer holds a list of doubts. Reversing the order, with checks first and commitment second, is the single most effective protection. When that is not possible, a short, conditional and refundable reservation is the next best thing, and a longer commitment should wait until the registry, the debts and the licences have been seen.

§ 9What lawyers add

A lawyer reads the paper in the original language, explains the effect of each clause and proposes changes. A lawyer can also hold the deposit in a client account, send formal notices, and attend the signing. These services cost a fee, which is small compared with the sums at stake. The professionals chapter explains how to find an independent one.

§ 10Taxes and the contract

The taxes on the purchase are normally paid after the deed, but the contract should say who bears which cost. The costs section of this handbook explains the taxes, and your lawyer can write the split into the paper. Where the seller is a non-resident, the buyer’s retention is recorded in the deed.

§ 11Reading in your own language

If a paper is only in Spanish, ask your lawyer to explain it clause by clause, and ask for a written summary in English. Never sign a paper because someone says it is standard. Standard forms are written by and for one side.

§ 12A sound approach

Do your checks first, if you can. If you must reserve, keep the amount small and the reservation short, and make it conditional on the checks. Insist on a written paper that says who holds the money and when it is returned. Pay by bank transfer so the payment leaves a trail, and the notary prefers that method at the deed too.

§ 13Developers

For off-plan purchases, the law requires advance payments to be secured and held in a separate account. Before paying an off-plan deposit, verify the developer’s registration, the ownership of the land and the building licence.

FAQRelated questions

Do I have to sign anything before the deed?

No. The deed before the notary is the document that transfers the property. Reservation papers and private contracts are optional steps that sellers and agents often ask for. Whether you sign depends on your own situation and your lawyer’s advice.

What is the biggest risk?

Losing the deposit because you signed something that made it non-refundable without realising. Another risk is signing before the checks are done. Have your lawyer read every paper first, and sign only what you understand.

Can I negotiate the terms?

Yes. The standard forms offered by agents or developers are starting points. You can ask for conditions, such as finance or satisfactory checks, a deadline and a right to withdraw. Your lawyer can propose wording that the seller can accept.
