LAU
Ley de Arrendamientos Urbanos — Spain's Urban Leases Act
Definition
The LAU — Ley 29/1994 de Arrendamientos Urbanos — is the national law governing residential and commercial leases in Spain. It sets the framework your contract sits inside: deposit, duration and renewal, repair obligations, notice, and how a tenancy ends.
Why it matters
Much of the LAU is mandatory in the tenant's favour for a residential lease. A clause in the contract that gives you less than the law does is not automatically valid just because you signed it.
Most move-out disputes come down to three of its articles: the deposit and its return, who pays for what repairs, and what happens if you leave early. Knowing which one your situation falls under changes the conversation with a landlord from opinion to rule.
The LAU is not the whole picture in Catalonia: regional rules add to it, including deposit registration and rent limits in designated areas. When they conflict in practice, that is a question worth asking a lawyer rather than guessing.
