You return to your Spanish home after the first winter storm and find damp behind a wardrobe. Was it already there when you bought, a recent leak from upstairs, or condensation in a closed room? That question matters more than how recently you received the keys. A problem discovered after purchase is not automatically a legally actionable hidden defect. Preserve the evidence, establish the cause and check the relevant deadlines promptly.

Start with the problem, not an accusation

The Spanish expression vicios ocultos refers to a particular legal concept, not every unwelcome repair in a resale home. Where the Spanish Civil Code's hidden-defect rules apply, article 1484 concerns defects that render the property unsuitable for its intended use or materially diminish that use. Apparent defects and certain defects a professionally expert buyer should have recognised are excluded. The condition of this particular property and the circumstances of the sale matter. Read the Civil Code's hidden-defect provision.

An old boiler reaching the end of its service life, damage caused after completion and a longstanding concealed leak raise different questions. Avoid assuming that the seller knowingly concealed something before the facts are established. A technical cause and a person's knowledge are separate matters.

Keep your expectations connected to what you bought and what was disclosed. Our guide to assessing a renovation property explains how to separate planned improvements from unresolved questions about the condition of an existing home.

Why an overseas buyer should check deadlines immediately

For the actions covered by article 1490 of the common Spanish Civil Code, the stated period is six months from delivery of the property. It is not six months from your discovery of the defect, your next visit to Spain or the date a contractor becomes available. Obtain advice promptly on the correct legal route and what steps preserve it. Do not assume that an informal email stops every relevant clock. See the delivery-based period in article 1490.

That provision should not be presented as the only possible rule throughout Spain. Where Catalan civil law applies, lack of conformity has a separate framework. Current article 621-23 addresses qualifying non-conformity existing at delivery and manifesting within three years, subject to its conditions. Article 621-44 separately provides a three-year period for the relevant remedies unless another legal period applies; for non-conformity, the starting point is when the buyer knows or can know of it. Consult the Catalan Civil Code provisions.

These are distinct tests, not an automatic six-year warranty. Applicable law, contract date and the transaction's circumstances need checking. Equally, do not decide without advice that every possible claim is lost because a particular hidden-defect period has elapsed. Different causes of action have different requirements.

Create a chronology before the evidence disappears

Make a short timeline beginning with the viewings and ending with the latest incident. Record when possession was delivered, when each symptom first appeared and who observed it. Keep original messages and images, with a separate copy for annotations. If a neighbour supplies information, identify it as their account rather than your own observation.

File itemWhat to includeQuestion it helps answer
Purchase recordListing, disclosures, contract and completion papersWhat condition was presented or agreed?
Incident recordDates, photographs, location and conditionsHow and when did the problem emerge?
Technical evidenceFindings, methods, limitations and repair historyWhat probably caused it, and when?
Cost recordItemised quotes, invoices and mitigation workWhat work and expense relate to the issue?

Urgent damage limitation and safety come first. Ask the attending professional to photograph relevant findings and record what was removed or replaced. Preserve useful components only where practical and safe. A flooded electrical installation is not something to leave untouched while waiting for a perfect evidence file.

Ask the expert to investigate age and cause

A quote to repaint a ceiling answers a price question. It does not establish where water entered, whether the underlying defect predates delivery or whether the proposed work fixes the cause. Give the inspecting professional those questions explicitly.

In a fictional example, an owner discovers a bathroom leak two months after buying. The plumber finds a loose fitting, but opening the adjacent enclosure also reveals old staining and previous patch repairs. Those observations may be relevant to history; they do not by themselves prove who knew what. A useful report separates visible evidence, likely explanations and conclusions that need further investigation.

Ask whether the issue is confined to your property or may involve communal services. Obtain relevant community records where available. If an inspection was completed before purchase, provide it too. The scope of a pre-purchase property inspection determines what that earlier report can reasonably tell you; a visual visit cannot guarantee discovery of every concealed problem.

Choose a remedy based on the file, not the first repair bill

Under the common Civil Code, article 1486 provides remedies including withdrawal from the contract on the stated terms or a proportionate price reduction assessed with expert input. Additional consequences depend on the circumstances. This is not an automatic entitlement to have any chosen renovation invoice reimbursed. Read the remedy provision.

Give your adviser the complete contractual record, including the arras agreement and earlier purchase commitments. A settlement should make clear which issue it resolves, what work or payment is agreed, when it will happen and how the result will be checked. Understand any release of further claims before signing it.

Some recently built resale homes may also raise questions about construction participants and their statutory responsibilities. The guide to Spanish new-build defects and responsibility periods covers that separate framework. The fact that you bought from a previous owner does not justify mixing all potential legal routes into one generic “warranty”.

Your next conversation should begin with four documents

Bring the purchase contract, evidence of delivery, a one-page incident chronology and the clearest technical material available. Add the remaining papers from your Spanish property purchase file as needed. This is more efficient than forwarding a long message chain without dates or a defined question.

If you are planning a purchase and want to organise the checks before committing, tell us where you are looking and what you need to establish. If a defect has already appeared, arranging timely legal and technical assessment of your evidence is the immediate priority.
