What contracts are signed when buying off-plan property in Spain?
There are three main documents in an off-plan purchase: the reservation agreement, the private purchase contract, and the title deed signed at the notary on completion day. Each stage has different legal implications.

- Private purchase contract: locks in price, spec, timeline and payment schedule
- Title deed: signed at the notary on completion, transfers ownership
- Bank guarantee letter: certifies that your deposits are protected
- All documents should be reviewed by your independent lawyer before signing
An off-plan purchase in Spain involves a sequence of legally binding documents. The first is the reservation agreement (contrato de reserva), which secures your chosen unit while contracts are drafted. The second and most important is the private purchase contract (contrato privado de compraventa), which locks in the price, unit specification, completion date and payment schedule. The third and final document is the public title deed (escritura publica de compraventa), which is signed at the notary on completion day and transfers legal ownership to you.
The reservation agreement
The reservation agreement (contrato de reserva or documento de reserva) is a short document signed when you decide to buy a specific unit. It records the property, the agreed price, and the reservation fee being paid. It takes the unit off the market and gives you time for your lawyer to review the full purchase contract. Some reservation agreements include conditions under which the fee is refundable. The document is usually 2 to 4 pages and is the start of your legal commitment.
The private purchase contract
The private purchase contract (contrato privado de compraventa) is the central legal document of the off-plan purchase. It is signed within 30 days of the reservation and sets out in detail: the full description of the property and its specification, the agreed purchase price, the payment schedule and due dates, the expected completion date and any grace period permitted for delays, the bank guarantee arrangement for your deposits, and the remedies available to each party in the event of non-performance. This contract must be reviewed thoroughly by your independent lawyer before you sign.
The bank guarantee letter
For each stage payment you make before completion, the developer should provide a bank guarantee letter (aval bancario or seguro de caucion) from an authorised bank or insurance company. This certificate confirms that your payment is protected and will be returned in full if the developer fails to complete. These letters are not a separate contract you sign, but they are legal documents you must keep safely, as they are your route to a refund if things go wrong.
The notarial title deed
On completion day, you attend the Spanish notary (notaria) to sign the title deed (escritura publica de compraventa). This is the formal legal transfer of ownership from the developer to you. The notary verifies the identity of both parties, reads the document aloud, and certifies the signature. The deed is then registered in your name in the Spanish Land Registry. If you have a mortgage, the mortgage deed is signed at the same time.
Other documents you may encounter
You may also receive the homeowners association statutes and budget (for community fees), the energy performance certificate, the building completion certificate from the local architect, and the keys to any storeroom or parking space. Your lawyer will verify that all required documents are in order before the notary appointment.
Why This Matters in Costa del Sol
The Costa del Sol off-plan market is well regulated and developers use standardised contract structures. However, specific clauses vary and independent legal review is essential on every purchase.
Common Mistakes to Avoid
A Dutch buyer in Marbella reserves a penthouse and pays 10,000 euros. Their lawyer reviews the private purchase contract within 30 days and identifies a clause that does not adequately specify the developer's obligations in the event of delays. The lawyer negotiates an amendment before the buyer signs, adding clear remedies if completion is delayed beyond 12 months.
Legal Note: The private purchase contract is a private document, not notarially certified. However, it is fully legally binding under Spanish law. The title deed is the notarially certified document that enables land registry entry.

Off-plan property refers to a residential or commercial property that is purchased before construction is complete. The buyer agrees to purchase based on architectural plans, CGIs, show apartments and a specification document rather than a completed building. Payment is typically made in stages tied to construction milestones.
A reservation agreement is a contract signed when a buyer pays an initial holding deposit to secure an off-plan or new build property. It removes the property from sale for a defined period, typically 14 to 30 days, while due diligence is conducted and the main Private Purchase Contract is prepared. The reservation fee is typically 1% to 3% of the purchase price or a fixed amount such as 5,000 to 15,000 euros.
The Private Purchase Contract (Contrato Privado de Compraventa or PPC) is the main legal agreement between a buyer and developer in an off-plan property transaction. It sets out all the terms of the sale including the purchase price, full payment schedule, completion date, property specification, bank guarantee obligations, penalties for delay, and dispute resolution. It is signed after the reservation stage and typically involves payment of 10% to 30% of the purchase price.
A bank guarantee (aval bancario) is a legal commitment from a Spanish bank to refund a buyer's stage payments if the developer fails to complete the property within the agreed timeframe or becomes insolvent. It is a mandatory legal requirement for all off-plan property purchases in Spain under Ley 57/1968 (updated 2015). Bank guarantees should be obtained for each stage payment individually.
The title deed (escritura publica de compraventa) is the notarised legal document that transfers ownership of a Spanish property from the seller (or developer) to the buyer. It is signed in the presence of a Spanish notary on completion day, records the purchase price and all relevant details, and is then registered at the Land Registry to formally establish the buyer as the legal owner.
