Subletting & assignment 3 min read · published September 11, 2025

If you are a tenant considering subletting your home or are renting it to someone else, it is important to know the legal limits on subletting price in Spain. Knowing how much a sublessor can charge, how it relates to the main rent and what rights you have against abusive charges helps you avoid conflicts and protect your contract. In this article we explain, in plain language, the applicable rules, how to calculate a reasonable price, which documents to gather and what steps to take if you suspect abuse. We also indicate official resources and action models aimed at tenants who need to resolve doubts or file a claim.

What does "subletting price" mean?

The subletting price is the amount the sublessor (the person who grants use) charges the subtenant to use the dwelling or a room. It cannot always be set freely: the relationship between the main rent and the subletting, the included services and the original contract are relevant to assess its legality.

Legal limits and applicable rules

In Spain the rules on urban leases and the validity of subletting are interpreted in light of the Ley de Arrendamientos Urbanos and the Civil Code. If the subletting exceeds what is allowed in the main contract or constitutes unjust enrichment, the tenant-holder may face sanctions or contract termination. For procedural matters and claims, the Courts of First Instance are the competent venue.[1][2]

In practice, the proportionality between the main rent and the subletting is key to assessing abuses.

How to calculate a reasonable price

To set or evaluate a subletting price, consider several objective factors:

  • Rent proportion: compare the proportional part of the dwelling being sublet with the main rent.
  • Included services: add the cost of utilities, community fees and services charged to the subtenant.
  • Duration and temporality: short sublets may justify different prices than long contracts.
  • Comparables: check prices of similar rentals in the area to know the market reference.
Keep copies of all payments and written agreements to demonstrate the agreed price.

What to do if you are overcharged

If you believe the sublessor is charging an abusive price, you can follow these steps:

  • Claim in writing to the sublessor detailing the discrepancy and requesting refund or adjustment.
  • Gather evidence: main contract, subletting contract, receipts, comparable ads and communications.
  • Seek advice: municipal guidance services, consumer associations or free legal aid if applicable.
  • If no agreement, file a claim in the Court of First Instance or request mediation if available.
Respond to notifications or judicial deadlines promptly to avoid losing rights.

Preguntas frecuentes

¿Puede el inquilino subarrendar sin permiso del propietario?
No siempre; el contrato principal puede limitar o prohibir el subarriendo. Si el contrato lo prohíbe, subarrendar sin permiso puede dar lugar a la rescisión del contrato.
¿Existe un tope legal para el precio de subarriendo?
No hay un tope único en la ley, pero los tribunales valoran la proporcionalidad y la buena fe. Precios claramente superiores al mercado o que incluyan cobros ocultos pueden ser considerados abusivos.
¿Qué pruebas son más útiles en una reclamación?
Signed contracts, payment receipts, written communications and comparable ads in the area are key evidence.

How-To

  1. Document the price: request and keep signed receipts from the sublessor.
  2. Compare: collect ads and comparable contracts to justify that the price is abusive.
  3. Claim in writing: send a letter or email requesting refund or adjustment and set a response deadline.
  4. If there is no agreement, file a claim in the Court of First Instance with the compiled evidence.

Key takeaways

  • The subletting price must be justified by the portion of the dwelling and included services.
  • Keeping contracts and receipts improves your chances in a claim.
  • If there is no friendly solution, judicial action or mediation are options.
