Build a clear case before choosing the next step

A Spanish property dispute becomes easier to assess when the promise, alleged breach and requested outcome are clear. Start with the actual contract and evidence rather than a broad statement that the other party has been unfair. Different claims can have different remedies, procedures and time limits.

This guide helps you prepare for legal advice about a property contract. It does not decide whether a breach occurred, calculate your deadline or provide wording for an individual claim. Use it alongside private purchase contracts and keep the complete documents rather than selected extracts.

Identify the agreement and the parties

Collect the signed contract, annexes, amendments, reservation terms and correspondence. Establish who contracted, in what capacity and for which asset or service. An agent, seller, developer and contractor may have different obligations.

Record the property references and the transaction stage. A disagreement before a purchase contract, a failed completion and defective renovation work are not interchangeable. The lawyer needs to know which promise was made and when performance was due.

If a translation was used, retain both language versions and any clause identifying the governing text. A summary prepared for convenience may omit qualifications that matter to the dispute.

Explain the breach through a short chronology

Create a dated sequence of the agreement, payments, promised actions, notices, events and responses. Distinguish facts you can evidence from assumptions about the other person’s motives. Keep the chronology short enough for the adviser to identify the important points.

The Spanish Civil Code contains the general framework for contractual obligations and:

incumplimiento

That means non-performance or breach. The relevant remedy depends on the actual obligation, facts and applicable law, not simply on using that label in a message.

Decide what outcome you are seeking

Explain whether you want performance, correction, repayment, termination, compensation or a negotiated change. Ask the lawyer which outcomes may be available and what evidence each requires. Different remedies can have different consequences for the rest of the transaction.

Do not assume that every delay permits cancellation or that every reservation payment is refundable. The agreement, mandatory rules, seriousness of the issue and the parties’ conduct may matter.

Use reservation agreements and finance conditions where relevant. A disappointment about borrowing is different from an agreed finance condition that has been properly triggered.

Preserve evidence proportionately

Keep advertisements, plans, photographs, invoices, receipts, reports and messages relevant to the promise and loss. Preserve the original files where possible and record dates. Avoid altering documents to make them easier to present.

For a physical defect, obtain appropriate technical evidence and ask before destructive investigation or permanent repair removes important information. Urgent safety work may still be necessary; document the circumstances and seek timely advice.

Use structural investigations and marketing claims to identify supporting records. Evidence should explain what happened, not simply repeat the conclusion you want the other party to accept.

Check time limits at the beginning

Ask the lawyer to identify every potentially relevant time limit, its starting point and any transitional rule. Contract claims, defects, consumer issues and property rights can follow different provisions. A widely quoted general period may not govern your case.

The Civil Code’s general personal-action framework includes a five-year rule where no special period applies, but that is not a universal property-dispute deadline. Ask about the actual classification, when performance became enforceable and whether another rule controls the claim.

Do not wait for a long informal conversation to end before obtaining deadline advice. Nor should you assume that any complaint, email or report automatically interrupts or suspends every applicable period.

Obtain advice before sending a formal demand

Ask who should receive the demand, what it should say and how delivery should be evidenced. The recipient’s legal identity and address matter. A message to an intermediary may not be the same as notice to the contracting party.

Avoid making admissions, threats or a final settlement offer before understanding the consequences. Keep communications factual and proportionate. If you are offered a release or waiver in return for a small payment, have its scope reviewed.

Use document formalities where representation, authentication or a foreign document is involved. A properly delivered document still needs the right substantive content for the purpose it is intended to serve.

Check the current pre-court process

Organic Law 1/2025 introduced important rules concerning appropriate dispute-resolution activity before many civil proceedings, with exceptions and specific requirements. Ask the lawyer which route applies to the actual claim.

Do not assume a casual negotiation automatically satisfies a procedural requirement or that every urgent or specialist case follows the same path. The subject, parties, evidence and confidentiality arrangements may matter.

Keep the proof of the required process and advice about its effect on deadlines. A sensible attempt to settle can be useful, but it should be coordinated with the legal strategy rather than allowed to create avoidable uncertainty.

Separate a consumer complaint from a court remedy

Where a business supplied a service or marketed a property to a consumer, the Junta’s complaints guidance explains available consumer routes. The appropriate route depends on the parties and issue.

A complaint process may help resolve conduct or service concerns without determining every contractual right. Ask whether arbitration, negotiation, court proceedings or another step is needed for the outcome sought.

Do not assume filing a complaint automatically stops a limitation period, suspends a completion obligation or protects a right to cancel. Keep administrative and private-law steps on the same chronology, with their separate purposes understood.

Assess the costs and practical recovery

Request a staged scope and estimate for legal work, technical reports, translations and potential proceedings. Ask what is fixed, what depends on events and what costs may be recoverable or payable to another party.

Consider the counterparty’s ability to comply or pay. A successful legal argument and actual recovery are different practical questions. Ask whether security, insurance or another source of recovery is relevant.

Keep the property’s ongoing costs visible while the dispute continues. Mortgage payments, insurance, community charges and temporary accommodation can affect the household even when the legal process is progressing properly.

Document any settlement and next steps

If agreement is reached, ask the lawyer to record exactly what is paid, done, released or preserved. Identify dates, documents, tax questions and the consequences of non-performance. A short friendly message may leave important parts unresolved.

Keep the final agreement with evidence of payment or completed work and any updated property records. The strongest preparation is a clear file that connects the original promise, the alleged breach, the legal route and the practical outcome, allowing advice to focus on resolving the actual problem.

Give the adviser a clear evidence index

Number the important documents and attach each to the event it supports in the chronology. Keep the signed agreement, payment evidence, notices and technical reports easy to locate. If a document is missing, mark the gap and explain who may hold it. This is more useful than sending a large unsorted message history without identifying the disputed promise. Ask which additional evidence is worth obtaining and whether any proposed step could affect confidentiality, deadlines or the legal strategy. Before accepting a settlement, compare its actual terms with the remedy originally sought, including unfinished work, releases, costs and the evidence needed to close the matter.
