Buying Off-Plan in Marbella: What to Check Before Paying a Reservation

In a competitive new-development market, the reservation payment is often presented as the quickest way to secure a unit while the paperwork follows. That sequence may be commercially convenient, but it places the buyer’s first meaningful risk at the very beginning of the process.

A reservation payment is not an administrative formality. It is money transferred before the buyer has completed the same level of legal, technical and financial review that would normally precede a property purchase.

Before paying, the buyer should know precisely what is being reserved, who is receiving the money, what legal and planning position exists, how the payment is protected, and what happens if the transaction cannot proceed on the terms originally presented.

Identify exactly what is being reserved

The development’s commercial name is not enough. The reservation document should identify the legal entity acting as seller or promoter, the exact unit, floor, orientation, parking space and storage room, together with the agreed price, applicable taxes and the version of the plans and specifications that form part of the offer.

The payment schedule also matters. Buyers should distinguish the reservation amount from later instalments, confirm whether every payment is credited against the purchase price, and understand when the reservation expires. If the unit is marketed through an agent, the document should make clear whether the agent receives the money on behalf of the promoter and under what authority.

The legal entity receiving the money and the property being reserved should be unambiguous. A brand name, brochure reference or informal unit label is not a substitute for a precise contractual description.

Verify the promoter, the land and the planning position

Independent legal review should begin with the promoter and the land. The company signing the agreement should be checked against the entity that owns the development site or holds the legal right to build on it. A current Land Registry report can identify the registered owner and disclose mortgages, easements and other registered limitations affecting the plot.

The planning position should be checked directly, not inferred from construction activity or marketing material. This includes the building licence and any relevant conditions, amendments or municipal proceedings. Marbella’s planning department publishes licence procedures and provides an information office for enquiries about the status of planning files.

If a building licence has not yet been granted, the contract should state that fact plainly. The buyer then needs a clear deadline and an express refund mechanism if the licence is not obtained, rather than an open-ended promise that approval is expected shortly.

Request the Andalusian information document

For homes offered at project or construction stage in Andalucía by a business or professional, including an intermediary, a Documento Informativo Abreviado (DIA) must be delivered free of charge to a consumer who requests information. Merely making it available is not the same as delivering it. These consumer rules should not automatically be assumed to cover a commercial purchaser acting outside consumer status.

The DIA covers the parties and project professionals, plans and usable area, specifications, price and payment terms, guarantee and special-account details, the promoter’s title and charges over the land, licensing information, construction stage and delivery timing. It must also mention the right to request the proposed contract. Ask for that contract and the supporting documents before committing; the architect is identified, and the contractor and site director are identified where already appointed.

The brochure is not due diligence. Marketing materials can form part of what has been offered, but they do not replace the documents needed to verify ownership, planning, payment protection and contractual risk.

Protect every advance payment

Under the First Additional Provision of Spain’s Building Act 38/1999, the statutory guarantee obligation applies from the granting of the building licence. It covers housing advances, applicable taxes and legal interest, using bank security or surety insurance. Before that point, do not assume the same statutory cover already exists: your lawyer should assess the proposed payment and any express protection before you transfer it.

Housing advances within this regime must enter a special account, separate from the promoter’s other funds and dedicated to construction. A payment described as a reservation or paid to an intermediary still needs legal classification: ask whether it is a purchase-price advance and which protection actually covers it.

Never transfer an advance payment to an unrelated account merely because the sales timetable is tight. Before sending funds, the buyer’s lawyer should confirm the account holder, the payment reference and the legal basis on which the recipient holds the money.

A general “bank guaranteed” claim is insufficient. The guarantee should identify the buyer, the unit and the protected amount. Before each transfer, ask your lawyer to check the individual document, payment schedule, coverage period and evidence of previous payments. A guarantee already covering the agreed schedule may not require a separate new document for every instalment.

Treat the reservation contract as a real contract

Reservation agreements are often short, but brevity does not reduce their effect. The document should explain whether the payment is refundable, the precise circumstances in which it may be retained, the period available for legal review, and what happens if the promoter changes the unit, price, plans or timetable.

The buyer should also decide whether a financing condition is necessary. A mortgage valuation below the purchase price, a lender’s refusal or a change in the buyer’s circumstances will not automatically create a right to recover the reservation unless the contract or applicable law provides one.

Labels such as “non-refundable” do not settle the issue. Where consumer law applies, unfair terms may be void under Articles 82–83 of the Consumer Protection Act. That does not make every reservation refundable at the buyer’s discretion. The complete agreement, pre-contract information and circumstances must be reviewed before relying on any exit right.

Put the delivery timetable and change risk in writing

For the DIA, Andalusian rules accept a delivery quarter and year. As a practical contractual safeguard, ask for an enforceable delivery deadline, a final agreed cut-off date, clearly limited extension grounds and the consequences of delay. The additional cut-off date is a negotiated protection, not a universal statutory formality.

The acquisition contract must state the refund obligation for missed construction deadlines or absent lawful-occupation documentation, and identify the guarantor and payment account. The statutory framework provides for repayment or an agreed extension. Enforcement needs legal advice on the applicable notice requirements and deadlines; a refund is not necessarily immediate.

A delivery date without a clear long-stop date and exit mechanism is incomplete. The contract should also control permissible changes to floor area, layout, materials and communal facilities, specify any tolerance, and explain the treatment of upgrades and buyer-requested variations.

Separate legal due diligence from the sales process

The buyer’s lawyer should be independent of the promoter, the selling agent and the development’s preferred suppliers. The review normally extends beyond the reservation form to title, planning, corporate authority, registered charges, the draft private purchase contract, advance-payment security, taxes and costs, financing arrangements over the site, assignment rights and the documents required at completion.

Independent advice should be in place before payment, not only before the private purchase contract. That is when the buyer still has maximum leverage to require documents, correct unclear terms or decline an inadequately protected reservation.

Legal review is not technical review. Where floor areas, specifications, views, levels, retaining structures or construction quality are material to the decision, an independent architect or surveyor can examine matters outside the lawyer’s scope.

Define what must exist at completion

The contract should not allow completion to be triggered simply because the promoter says the property is ready. It should specify the documents required for lawful occupation, final plans and specifications, utilities, community arrangements where applicable, relevant building insurance and cancellation of any development finance that should not remain against the home.

In Andalucía, occupation of a completed building that complies with its authorisation and permitted use can fall under a declaración responsable, under Article 138 of Law 7/2021. It is therefore inaccurate to insist that every handover requires a newly issued first-occupation licence. The buyer’s lawyer and technician should verify the applicable route, the required supporting documents and compliance; filing a declaration does not legalise a non-compliant building.

Snagging should also be planned. A pre-completion inspection, written defect list, access for reinspection and a realistic rectification process are more useful than a general promise to address issues later. Snagging does not replace the statutory guarantees that may apply after completion, but it can prevent avoidable disputes at handover.

A practical reservation decision

A sound decision can be reduced to three questions. Are the promoter, land and planning position independently verified? Has the lawyer confirmed the legal nature, recipient and actual protection of each proposed payment? Are the timetable, permitted changes and refund rights clear enough to enforce?

If any answer is no, the buyer may need a written condition, further documentation or a revised contract before funds move. The best decision may be to pause the reservation, not to reject the property. A well-structured development should withstand reasonable document requests.

Private-advisory conclusion

Off-plan buying can offer access to a new home, staged payments and a defined specification, but the commercial attraction should not obscure the order of operations. Documents first, payment protection second, and commitment only when the buyer understands both the asset and the contract.

In Marbella, where new developments can be marketed internationally and units may appear to move quickly, speed should come from an organised review rather than from skipping it. The purpose of due diligence is not to eliminate every development risk; it is to identify which risks are acceptable, which can be contracted around and which justify walking away.
