For a US, UK or other non-EU buyer, buying off-plan in Spain means committing cross-border funds to a home that is not yet complete. The buyer takes developer, construction, licensing, currency and delivery risk. Spanish law protects qualifying advance payments, but the actual contract, payment account and guarantee documents must be checked before each transfer—not after a problem arises.
Key Takeaways
- Identify the legal developer and confirm its right to develop and sell the land.
- Check that the competent authority has granted the relevant building licence; “applied for” is not the same.
- Do not assume every payment is automatically protected: inspect the guarantee or insurance documentation and payment account.
- Attach plans, specifications, price, payment milestones and delivery terms to the contract.
- Define what happens if the project is delayed, altered, not licensed for occupation or not delivered.
- Before completion, check the finished property, legal documentation, defects and outstanding contractual obligations.
- Align payment milestones with source-of-funds checks, currency conversion, mortgage conditions and the buyer’s ownership structure.
Why Buying Off-Plan in Spain Needs Different Due Diligence
In a resale, the buyer can inspect an existing home and investigate its current title and condition. In an off-plan purchase, the product is partly a set of promises: plans, specifications, licences, construction milestones and a future completion date. The contract therefore carries more of the risk.
The Building Act addresses building participants, responsibilities and protection of advance amounts for homes. The Civil Code supplies the general framework for contractual obligations. Neither removes the need to examine the project’s individual documents.
Checks Before Paying a Reservation
The contracting company
Confirm the exact company receiving the reservation and signing the private contract. A development’s trading name may differ from the legal seller. Obtain corporate identification and verify who can bind the company.
Ownership and charges on the land
Review Land Registry information for the development plot. Confirm ownership, mortgages, easements, seizures and any arrangements affecting future units. If lender finance burdens the plot, the contract should explain the mechanism for releasing the buyer’s completed unit from that charge.
Planning and building permission
Ask for the granted building licence and compare it with the marketed unit, plans and phase. Planning checks must be made with the competent municipality for that project. No development in Marbella or elsewhere should be described as licensed until the address-specific municipal file and granted authorisation have been confirmed directly.
Marketing information
Royal Decree 515/1989 governs housing offers, promotion and advertising made in a business or professional activity to consumers. It must be read alongside applicable autonomous-community consumer-information rules; it is not a universal rule for every private sale. Its Article 3.2 makes advertised characteristics and conditions enforceable even when not expressly repeated in the contract.
Keep dated copies of advertising, floor plans, common-area descriptions and the memoria de calidades (specification of materials and finishes). Have these documents incorporated as contractual annexes, identifying the version agreed, rather than relying on a sales brochure that may later change.
Protecting Advance Payments
Under Additional Provision One of Law 38/1999 (the Building Act), a developer receiving buyers’ money towards constructing homes must, from the grant of the building licence, guarantee repayment if construction does not start or the home is not completed and delivered within the agreed period. The protection must cover advance payments, including applicable taxes and legal interest, through surety insurance with an insurer authorised to operate in Spain or a joint-and-several bank guarantee from an authorised credit institution.
The developer must receive advances into a special account segregated from its other funds, which may be used only for the construction of the homes. The bank opening that account must require the prescribed guarantee. A normal company account or a general assurance that the developer has finance is not a substitute.
The purchase contract must identify the insurer or guarantor and the bank and account for advance payments. It must also record the developer’s refund obligation if construction does not start or finish within the agreed periods, or the required occupation document is not obtained. At the signing of the purchase contract, the developer must deliver evidence of the guarantee individualised to the advance sums payable by the buyer; an individual insurance policy must identify the buyer and home.
Before each transfer, check the contract and guarantee evidence together:
- Confirm the buyer’s identity and the specific property or development phase.
- Reconcile the payment and cumulative covered amounts, including applicable taxes and legal interest.
- Verify the agreed delivery date, guarantee duration and any extension.
- Match the receiving bank and special account to the contractual payment instructions.
- Verify the authorised insurer or guarantor and the procedure for making a claim.
- Obtain updated evidence if the buyer, developer, guarantor, account or payment schedule changes.
Missing individualised documents or changed parties are serious compliance warning signs: pause payment and obtain advice. They do not automatically mean that the buyer has no statutory claim. Possible rights against the developer, insurer, guarantor or receiving bank require review of the dates, payments, documents and applicable law; poor paperwork should neither be ignored nor treated as proof that all protection has disappeared.
Clauses the Private Contract Should Address
Property and specification
Identify the unit, parking, storage, terraces, approximate areas and rights in common elements. Attach plans and the specification. Limit the developer’s ability to substitute materials, change layout or reduce usable space without a defined justification and remedy.
Price and tax
State the full price, applicable tax treatment, payment schedule, extras and who bears each cost. Confirm whether optional upgrades affect payment protection or the completion balance.
For funds arriving from abroad, record the euro amount due at each milestone, permitted payment account and evidence needed by the receiving bank and regulated professionals. A buyer funding in dollars or sterling bears exchange-rate and transfer-timing exposure unless the contract expressly provides otherwise. Never redirect a payment on emailed instructions without independently verifying the recipient and whether the protection still applies.
Licence and construction conditions
Record the status of the building licence and any condition that must be satisfied before payments or completion. The contract should not treat a marketing estimate as proof of regulatory approval.
Delivery date and delay
Set an exact contractual delivery deadline, not merely a marketing estimate or approximate quarter. Define any grace period, notice requirements, grounds for a justified extension, refund procedure and effect on payment guarantees.
Additional Provision One provides a choice where construction has not started or the home has not been delivered as agreed: terminate and seek repayment of advances, including applicable taxes and legal interest, or grant an extension documented in an additional contract clause with a new construction-completion and delivery date. Review the contract, any valid extension, evidence of non-performance and required notices before making a claim. Do not assume that missing an informal estimate automatically cancels the contract.
Completion conditions
Define the documents and physical state required before the buyer must complete. The relevant occupation or habitability procedure varies territorially, so confirm the correct instrument with the municipality rather than relying on one label nationwide.
Assignment and mortgage
If the buyer may want to transfer the contract before completion, address assignment restrictions and fees. If funding depends on a mortgage, clarify whether finance is a condition; do not assume a lender’s eventual approval.
Before the Notary Completion
The buyer should receive and review the completion pack in time to act. Depending on the project, this may include:
- Completion and occupation documentation.
- Updated Land Registry and cadastral details.
- Energy and building documentation.
- Ten-year structural insurance where legally required, together with other applicable building guarantees.
- Community statutes and initial budgets.
- Confirmation of release from developer financing.
- A statement of payments and completion balance.
Arrange an independent technical inspection or snagging review. Record visible defects and contractual deviations in writing, with photographs and a remedy timetable. Do not confuse a snag list with acceptance of a materially incomplete or legally non-compliant property.
Before the final deed, recheck whether the named buyer and funding route still match the intended Spanish and home-country tax, succession and beneficial-ownership plan. A late substitution of an individual, company or other vehicle can affect the contract, developer consent, tax treatment, finance and compliance review; it should not be treated as an administrative name change.
Defects and Building Responsibilities
Article 17 of the Building Act distinguishes liability periods for material damage caused by building defects:
- One year for execution defects affecting finishing or completion elements, for which the constructor is responsible.
- Three years for defects in construction elements or installations that breach habitability requirements, with liability allocated to the responsible building participants under the Act.
- Ten years for structural defects affecting foundations, supports, beams, floors, load-bearing walls or other structural elements and directly compromising mechanical resistance and stability, with liability allocated under the Act.
These periods run from formal acceptance of the works without reservations, or from correction of the reservations, not automatically from the buyer’s deed or discovery of the defect. The developer also has the joint liability towards buyers specified in Article 17. These liability periods do not mean that one-, three- and ten-year insurance policies are all compulsory: insurance requirements must be checked separately under Article 19 and Additional Provision Two.
Under Article 18, actions to enforce Article 17 liability generally have a two-year limitation period from the occurrence of the damage. That is distinct from the one-, three- and ten-year periods within which the relevant damage must arise, and from any surviving contractual claim. Notify defects promptly, preserve technical evidence and have the correct defendant, limitation date and any interruption of time assessed without waiting for a sales-office promise.
Warning Signs
- Pressure to pay before independent contract review.
- A building licence described only as pending or expected.
- Payment to an account or company not identified in the contract.
- Vague references to a “general guarantee” without supporting documents.
- Plans or specifications that are not contractual annexes.
- Broad unilateral variation rights.
- An estimated delivery date with no practical remedy.
- A request to complete before the required municipal and building documents are verified.
Frequently Asked Questions
Is buying off-plan in Spain safe?
It can be managed safely when the developer, land, licence, contract, payment protections and completion documents are independently verified. No development is risk-free, and statutory protection should not be treated as a substitute for checking the actual paperwork.
Is every advance payment automatically protected?
The developer has statutory duties to protect qualifying advances from the grant of the building licence, including applicable taxes and legal interest. Verify the special account and individualised guarantee before paying. Missing documentation is a serious compliance problem, but does not by itself rule out statutory recovery rights.
Can I cancel if the developer is late?
Additional Provision One allows termination with repayment of advances, applicable taxes and legal interest, or a documented extension with a new completion and delivery date, where construction has not started or delivery has not occurred as agreed. Review the contractual deadline, valid extensions and claim requirements before exercising that choice.
Should I complete without occupation documentation?
Completion should be assessed against the contract and the correct municipal procedure for that location. Obtain direct confirmation of the project’s status and advice on the consequences before signing or paying the balance.
