Buying off-plan means committing to a home that may not yet be completed. The critical questions concern the exact unit, documents, staged payments, protections and handover conditions.
What off-plan means in practice
The property may be at design stage or under construction. You may be shown plans, a model or computer-generated images rather than the finished rooms.
Ask which construction and administrative milestones have been reached and which documents demonstrate that status. Do not treat planned amenities as completed facilities.
Information before the first payment
Identify the developer and the legal entity receiving money. Request the exact unit description, plans, specifications, surface areas, annexes and the anticipated contractual timetable.
Check which features are binding commitments and which are illustrations. If a terrace, parking space or particular layout matters to you, ask where it appears in the written documents.
Reservation and private contract
A reservation document can create obligations even if it is short. Review the parties, amount, property identification, deadlines and conditions for proceeding or withdrawing.
Ask what the next contract will require, when further payments become due and whether the agreement contains a finance contingency if that matters to you. Never assume all reservations are refundable.
Advance payments and protection
Spanish law provides for guarantees of certain amounts paid in advance for homes under construction where the statutory conditions apply. The relevant mechanism may involve a guarantee or insurance and specific handling of payments.
Ask for documentary evidence identifying the protection applicable to your particular payments, including the amounts and issuer where relevant. A general sales assurance is not enough.
Have an independent qualified professional review the payment and guarantee documents before committing substantial funds.
The payment calendar
Build a table showing each payment, its trigger, recipient, contractual basis and proof of transfer. Keep the contract and receipts together.
If you depend on mortgage financing, check whether you can meet interim payments from funds already available. A lender’s eventual mortgage may not cover every earlier payment.
Delivery dates and delays
Ask how the contract defines the expected delivery date, extensions, completion conditions and consequences of delay.
If you need the home by a fixed date, do not treat an approximate marketing estimate as sufficient. Have the actual clauses explained independently.
Changes to plans or specification
Save dated copies of the plans and specifications you received. Keep requests for changes separate from changes the developer has formally accepted.
If an important detail changes during construction, ask how the contract addresses substitutions, notification and your rights. Do not rely solely on telephone conversations.
Before each instalment
Confirm the contractual milestone, payment destination and supporting documents. Retain evidence of the transfer and any guarantee that applies.
Where something has changed or remains unclear, obtain professional advice before sending funds rather than hoping it will be resolved at completion.
Handover and record keeping
Prepare a folder for plans, specifications, signed contracts, payments, guarantees, correspondence, approved changes and handover documents.
At completion, check the actual property against the agreed documentation and follow the appropriate professional and contractual procedures for recording issues.
Understand the distinction between reservation and contract
A reservation is not necessarily a harmless expression of interest. Its legal consequences depend on the actual document, the parties and the terms. Identify what you are agreeing to, when the next contract must be signed and what happens if either party does not proceed.
Ask whether the document identifies the exact unit and its annexes, the agreed price and the conditions for paying or returning money. If financing is essential, check whether the agreement addresses failure to obtain a loan.
Never rely on a verbal description of refundability. Have an independent adviser examine the actual clauses before signing.
What to ask about the developer and the project
Establish the identity of the developer and the legal entity responsible for the transaction. Ask for relevant project and planning documentation and for evidence of the stage reached by the development.
Review the location of the unit within the building, orientation, adjacent spaces, access, parking and storage. Compare plans and specification versions so that you know exactly which documents apply to the property you are buying.
Distinguish between common facilities that are contractually included and amenities merely shown in promotional material or planned for a later phase.
A safe payment record
Create a table with the amount, date, contractual milestone, recipient, destination account and proof of payment for every instalment. Keep the corresponding contract and any applicable guarantee documents in the same folder.
Before paying, verify the payment instructions through a trusted channel. Unexpected changes in bank details deserve independent confirmation, particularly when instructions arrive by email.
If you are purchasing from abroad, allow sufficient time for international transfers and bank compliance checks. A transfer delay should not be discovered on the final day of a contractual deadline.
Handover and defects
Before accepting the finished home, inspect the actual property against the agreed plans and specification. Record issues clearly and ask how they will be addressed under the applicable contractual and legal arrangements.
Clarify which completion and occupancy documentation is relevant, how utilities will be activated and when community and other ownership obligations begin.
A sensible handover plan includes the practical details: keys, access devices, manuals, equipment warranties and contact information for reporting problems.
What a good document trail looks like
Create folders for marketing materials, dated plans, specifications, signed contracts, payment evidence, guarantees, accepted changes, correspondence and handover. Give documents meaningful names that include dates and versions.
For every important promise, note whether it appears in the signed contract, an annex, a written confirmation or only a conversation. A buyer’s recollection and a developer’s contractual obligation are not interchangeable.
If you are represented remotely, keep copies of authorisations and identify which person is permitted to sign, approve changes or release payments.
What can change during construction
Projects can experience changes in programme, suppliers or technical details. The contract and applicable law determine which changes may be made and what remedies or procedures apply. Ask your adviser to explain the relevant clauses before signing.
When notified of a change, compare the proposed revision with the dated document previously agreed. Ask for its effect on usable space, specification, cost and delivery. Record the response and any acceptance in writing.
Do not assume that a feature shown in a model apartment is automatically part of every unit. Verify the contractual specification for your precise home.
Planning the final months before handover
Several months before the anticipated completion, review your financing position, remaining payments, identification documents and availability to sign. Ask which completion documents will be provided and which steps depend on public administration or other third parties.
Prepare a practical inspection checklist covering finishes, doors, windows, sanitary fittings, kitchen equipment, heating and cooling, ventilation and any included annexes. A qualified professional can assist where appropriate.
Clarify how defects are reported and how the developer communicates remedial work. Retain photographs and dated correspondence. Keep the financial and technical handover records together for future reference.
Advance-payment guarantees: questions that matter
Ask which instalments fall within the applicable statutory protection, which entity issues the guarantee or insurance and which documents evidence protection for your specific amounts. The legal position depends on the transaction and relevant statutory requirements.
Confirm where payments must be made and retain bank evidence showing the recipient, date, amount and reference. Do not rely on a brochure statement that ‘all payments are protected’ without the appropriate documentation.
If the developer changes payment instructions unexpectedly, independently verify the new details through a trusted channel before transferring funds.
Distinguish three different deadlines
A reservation deadline may govern when you must sign a later agreement. A construction timetable may describe expected building progress. A contractual handover date determines obligations under the actual agreement.
Put all three on a calendar with the corresponding document. Do not treat a marketing completion estimate as though it necessarily carries the same legal effect as the signed contract.
Ask how permitted extensions, changes and delays are handled, and seek independent advice on material clauses before becoming committed.
A timeline for the buyer
At the information stage, collect plans, specifications, unit details, developer identity and evidence of project status. At reservation, review the legal effect of the document, deposit and conditions for withdrawal. Before the private contract, resolve questions about advance payments, guarantees and delivery.
During construction, track instalments against contractual milestones and preserve all payment evidence. When changes are proposed, compare them with the agreed documentation and obtain written confirmation of their consequences.
Before completion, check financing, the remaining balance, required documents and the arrangements for inspecting the finished home. At handover, keep a dated record of the condition of the unit and any issues reported.
When to stop and request clarification
Pause before payment if the exact unit is not clearly identified, payment instructions cannot be verified, the contractual consequences of withdrawal are unclear or the applicable protection of advance payments has not been explained.
Also seek clarification when the specification changes materially or the delivery timetable becomes inconsistent with your own obligations. Independent advice is especially valuable before a commitment becomes difficult or costly to reverse.
Final checklist
Can you identify the exact home? Do you know who receives each payment? Are the relevant protections documented? Are the delivery conditions clear? Can you afford the schedule without assuming unapproved financing?
Do you have a dated record of every significant promise? Are unresolved questions reviewed independently? If not, clarify them before transferring money.
