Rental deposit returns and disputes in Spain: how to get your fianza back when the landlord refuses (2026)

Getting your Spanish rental deposit (the fianza) back at the end of a tenancy should be straightforward: Article 36.4 of Ley 29/1994 (the LAU) gives the landlord one month from key handover to return the balance, after which legal interest accrues. In practice, deposit disputes are one of the most common conflicts in Spanish residential letting. This guide walks through what the landlord can and cannot deduct, and the step-by-step recovery route from an informal request to a court order, including the non-resident angle for tenants who have already left Spain.

What is the legal deadline for deposit return in Spain?

Article 36.4 of the LAU fixes a clear rule: the cash balance of the fianza that must be returned to the tenant at the end of the tenancy accrues legal interest (interes legal del dinero) once one month has passed from the tenant handing over the keys without the return having been made. The clock starts on the day the keys are handed over, not on the contract end date, so a tenant who stays a few extra days into the next month resets the start point.

The legal interest rate for 2026 is 3.25 per cent per annum, maintained from 2025 by budget prorogation until a new Ley de Presupuestos Generales del Estado sets a different figure, according to the Agencia Estatal de Administracion Tributaria. The interest is not punitive: it simply compensates the tenant for the time value of the withheld money. It runs on the outstanding balance after justified deductions, not on the full deposit if the landlord has lawfully withheld part of it.

This one-month window is the landlord’s hard deadline. A landlord who returns the deposit within the month but disputes a small cleaning charge is compliant; a landlord who ignores the tenant for six weeks and then returns the full amount still owes the interest for the two weeks of delay.

What can a landlord legally deduct from the deposit?

The LAU does not contain a closed list of deductions, but the purpose of the fianza, the obligations the law places on each party, and the resolution grounds in Article 27.2 together define what is legitimate. The table below sets out the categories a landlord can claim against and the boundary that protects the tenant.

Deduction category	Legal basis	What the landlord can claim	What the landlord cannot claim
Unpaid rent	LAU Art 27.2.a	Rent due and unpaid up to the exit date, including any period the tenant stayed beyond the contract end	Future rent for a contract the tenant lawfully ended
Unpaid utilities	Contract + Art 27.2.a	Water, electricity, gas and community bills the tenant was contractually liable for, evidenced by invoices	Bills that fell to the landlord under the contract or were already paid
Damage beyond normal wear	LAU Art 21.1, Art 21.4	Damage that goes beyond the small repairs from ordinary use that Art 21.4 makes the tenant’s responsibility: broken tiles, holes in walls, burnt worktops	Normal wear: faded paint, worn flooring, minor scuffs from daily living
Unauthorised alterations	LAU Art 23.1, Art 23.2	The cost of restoring the property to its prior state where the tenant made structural or config changes without written landlord consent	Alterations the landlord consented to in writing, or improvements that add value
Cleaning where the property is left in poor condition	Contract terms	A reasonable cleaning cost where the property is returned in a state clearly below how it was handed over	Ordinary end-of-tenancy cleaning if the property was returned clean
Late fees or penalties	Contract terms	Only where the contract expressly provides for them and they are proportionate	Punitive charges invented at exit without a contract clause

The single most common dispute is the line between normal wear and damage. LAU Article 21.4 places “small repairs that ordinary use of the dwelling requires” on the tenant during the tenancy, but it does not authorise the landlord to charge the deposit for the accumulated effect of years of ordinary use at exit. A landlord who tries to keep the deposit for repainting a flat that was last painted five years ago is overreaching; a landlord who charges for a door the tenant broke is within bounds.

The second common dispute is unauthorised works. Article 23.1 of the LAU forbids the tenant from making changes to the configuration of the dwelling without the landlord’s written consent. Article 23.2 gives the landlord, at the end of the contract, the choice between demanding the tenant restore the property to its prior state or keeping the modification, with no compensation due to the tenant. If the landlord chooses restoration and the tenant has already left, the cost of that restoration can be deducted from the deposit, but only with evidence: invoices, photographs, a comparison to the inventory signed at entry.

How does the deposit return work in Andalusia after January 2026?

For Costa del Sol tenancies, the regional layer changed on 24 January 2026. The Disposicion Adicional Sexta of Ley 5/2025, de 16 de diciembre, de Vivienda de Andalucia (BOE-A-2026-423) suppressed the obligation for landlords to deposit the fianza with AVRA, the Agencia de Vivienda y Rehabilitacion de Andalucia, for contracts signed from that date. The landlord now holds the deposit directly throughout the tenancy and returns it to the tenant at exit under the same LAU Article 36.4 one-month rule.

For contracts signed before 24 January 2026 where the fianza was already lodged with AVRA, the agency continues to return those deposits on request as the contracts expire, using the Modelo 810 return form, with the same one-month return window from the date of the request. The AVRA confirms on its official guidance page that “the Administration has one month from the date of the return request to return the deposit”. Pre-2026 contracts therefore still route through the agency; only the deposit obligation for new contracts is gone.

The practical effect for a deposit dispute is that a tenant in a post-January 2026 Andalusian contract has no agency intermediary to lean on: the recovery path runs directly against the landlord. A tenant in a pre-2026 contract can still ask AVRA to process the return, which removes the landlord’s ability to sit on the money, though the landlord can still contest deductions before the agency releases the balance.

What is the step-by-step recovery route when the landlord refuses?

The dispute resolution ladder in Spain has four rungs, each with its own evidence bar and timeline. A tenant should climb them in order: jumping straight to court without a formal demand weakens the case and invites the court to ask why earlier steps were skipped.

Step	Action	Timeline	Evidence needed	Cost
1	Informal written request (email or WhatsApp)	Day 1 to day 30 after key handover	Copy of the message, read receipt	Free
2	Formal burofax demand	After day 30 if no return or no itemised deductions	Contract, inventory, key handover record, utility statements	EUR 30 to EUR 75 depending on text length and certified receipt
3	Consumer arbitration (Junta Arbitral de Consumo) or AVRA complaint for pre-2026 Andalusian contracts	After the burofax is ignored or refused for 10 to 15 days	The full evidence file, the burofax, photographs, invoices	Arbitration is free; AVRA complaint is free
4	Court claim (demanda civil) in the Juzgado de Primera Instancia where the property is located	After arbitration fails or is refused by the landlord	The full evidence file, the burofax, the arbitration rejection if any	Abogado and procurador fees, typically EUR 600 to EUR 1,500 for a deposit claim, plus court filing fees

Step 1: the informal request

The first step is a plain written request to the landlord, by email or the same channel used during the tenancy, asking for the deposit back and for an itemised list of any deductions. This is not a legal formality; it is the courtesy that most courts and arbitration panels expect to see before a formal demand. Keep the message short: state the date keys were handed over, the deposit amount, the one-month LAU deadline, and a request for either the full return or a written breakdown of deductions within a specific number of days.

If the landlord responds with a deduction list, assess each item against the table above. If the landlord does not respond at all, move to step 2 on day 31.

Step 2: the burofax demand

A burofax is a verifiable postal communication sent through Correos, the Spanish postal service. It proves the sender, the recipient, the date of delivery, the content of the text and, if sent with certified receipt (acuse de recibo), that the recipient signed for it. It is the standard first formal step in a Spanish deposit dispute because it creates the paper trail a court or arbitration panel later expects, and it costs a fraction of a notarial requirement.

The burofax should: cite Article 36.4 of the LAU and the one-month deadline; state the deposit amount; list the justified deductions the tenant accepts, if any; demand return of the balance within a fixed period (typically 10 to 15 days); and warn that failure to return will trigger arbitration or a court claim with a request for costs and legal interest. Send it with a certified receipt and keep the Correos stamp and the signed delivery card.

If the burofax is refused at delivery, Correos returns it with a note that the recipient did not collect it, which a court treats as constructive refusal. If it is delivered and ignored, the tenant has clear proof of a formal demand going unanswered.

Step 3: consumer arbitration or the AVRA complaint

If the burofax is ignored or the landlord refuses to pay, the next rung is consumer arbitration. The Juntas Arbitrales de Consumo, attached to municipal or provincial consumer offices, offer a free, voluntary and binding dispute resolution route for consumer matters. Residential tenancy deposit disputes qualify because the tenant is a consumer of a housing service. Both parties must accept arbitration for it to proceed; if the landlord agrees, the panel issues an award (laudo) that is enforceable like a court judgment, usually within two to three months and without legal fees. If the landlord refuses arbitration, the panel issues a certificate of refusal, which is useful evidence in the later court claim.

For pre-2026 Andalusian contracts where the fianza is still held by AVRA, the tenant can file a complaint with the agency. AVRA’s procedure allows the tenant to challenge a landlord’s withholding, and the agency can release the deposit balance directly where the landlord cannot substantiate the deductions. This route is only available where the deposit was actually lodged with AVRA, which is not the case for contracts from 24 January 2026 onward.

Step 4: the court claim

If arbitration fails, is refused, or is unavailable, the final rung is a civil claim in the Juzgado de Primera Instancia for the district where the property is located. The LAU’s Title V fixes competence in the court where the property sits, regardless of where the parties now live. The claim (demanda) is filed through a Spanish abogado and procurador, and seeks: the deposit balance, legal interest from day 31 after key handover, legal costs, and where applicable a small additional sum for the inconvenience.

For a straightforward deposit claim, the ordinary civil process applies rather than the express eviction route, which is for non-payment of rent. The timeline is typically six to twelve months to judgment, depending on the court’s backlog. The tenant does not need to be physically present: the abogado and procurador handle the filings, and a tenant abroad can sign the power of attorney at a Spanish consulate or with a local notary who apostilles it for use in Spain.

How does a non-resident tenant recover a deposit from abroad?

A tenant who has left Spain faces a practical question: can the recovery route be run remotely? The answer is yes, with two mechanisms. First, a power of attorney (poder notarial) granted to a trusted person or directly to the abogado allows the representative to sign the burofax, file the arbitration request and pursue the court claim in the tenant’s name. The power can be granted at any Spanish notary, at a Spanish consulate abroad, or at a foreign notary followed by an apostille under the Hague Convention. Second, the consumer arbitration route can be initiated electronically through the Junta Arbitral’s online portal, with documents uploaded as PDFs, so a tenant abroad can start step 3 without travelling.

The cost benefit matters here. A deposit of EUR 1,500 on a typical Costa del Sol apartment does not justify a full court claim with EUR 1,000 of legal fees if the tenant has to fly back for hearings. Arbitration, which is free and can be run remotely, is the proportionate route for most non-resident tenants. The court claim becomes worthwhile only for larger deposits, a combined claim that includes unpaid rent or significant damage, or where the landlord’s refusal is part of a pattern that the tenant wants to stop.

What evidence does a tenant need to win a deposit dispute?

The evidence file is what wins or loses a deposit dispute. A tenant should assemble it at the start of the tenancy, not at the end. The minimum bundle is:

• The signed contract, showing the deposit amount and the tenancy dates.
• The entry inventory (estado de la vivienda), ideally with date-stamped photographs of every room, fixture and appliance. If the landlord did not provide one, the tenant’s own photographs from move-in day are admissible.
• The key handover record: a dated and signed note or email confirming the tenant returned the keys on a specific day, which sets the Article 36.4 clock.
• Utility bills for the final period, showing the tenant paid up to the exit date or that final readings were taken.
• The burofax and its delivery receipt.
• Any written communication in which the landlord stated deductions, with photographs or invoices the landlord claims support them.

The entry inventory is the decisive document. Without it, the landlord’s claim that the property was “perfect” at handover is an assertion; with it, the tenant can point to the pre-existing scuff, the already-chipped tile, the marked wall. A tenant who did not get an inventory at entry should send the landlord a set of move-in photographs by email on the first day, creating a dated record that is hard to dispute later.

How do deposit disputes interact with the wider tenancy framework?

A deposit dispute rarely happens in isolation. It often follows a tenancy that ended early, a rent dispute, or an eviction. The LAU framework connects these threads. Article 27.2.a lets the landlord resolve the contract for non-payment of rent, which is the basis for the express eviction process. Article 27.2.d lets the landlord resolve for damage caused dolosamente (deliberately) or for unauthorised works, which is the bridge between an Article 23 alteration claim and a deposit deduction. Article 27.1, incorporating Article 1124 of the Codigo Civil, gives either party the right to demand performance or resolution for any contractual breach, which is the general hook for a tenant’s counter-claim if the landlord withheld the deposit in bad faith.

Worked example: a EUR 1,800 Marbella deposit dispute

A tenant rents a Marbella apartment for EUR 1,800 per month and pays a EUR 1,800 fianza at signing in March 2026. The contract runs 12 months. In March 2027 the tenant gives the required 30-day notice, hands over the keys on 31 March 2027 with a signed handover note, and provides final electricity and water readings showing all bills paid. The entry inventory, signed by both parties, shows the apartment in good condition with one marked hallway wall noted.

On 15 April, the landlord emails to say they are keeping the full EUR 1,800 for: repainting the whole flat (EUR 900), replacing the hallway carpet (EUR 500), and a deep clean (EUR 400). The tenant disputes this: the flat was last painted before the tenancy, the hallway wall mark was in the entry inventory, and the apartment was left clean.

The tenant’s route:

1. On 20 April, the tenant replies by email disputing each item, citing the entry inventory for the hallway wall and the LAU Article 21.4 rule on ordinary wear, and asks for the full EUR 1,800 within 10 days.
2. The landlord does not respond. On 2 May (day 32 after key handover), the tenant sends a burofax demanding the EUR 1,800 plus legal interest from 1 May, with a 10-day deadline and a warning of arbitration.
3. The burofax is delivered and ignored. On 15 May, the tenant files an arbitration request with the local Junta Arbitral de Consumo, uploading the contract, inventory, handover note, final utility bills, the email exchange, the burofax and its delivery receipt.
4. The landlord accepts arbitration. The panel reviews the inventory, finds the hallway mark was pre-existing, finds repainting a five-year-old paint job is ordinary wear not damage, and finds the cleaning charge unsupported by photographs. The panel awards the tenant EUR 1,800 plus interest from 1 May and costs.

The whole process takes about three months from burofax to award, at no cost to the tenant, and without a court appearance. If the landlord had refused arbitration, the tenant would have escalated to a court claim with the same evidence file, expecting a similar outcome but a longer timeline and legal fees that the court would likely order the landlord to pay.
