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 giving them less than the law does is not valid just because both sides signed it — which makes a contract copied off the internet a real risk rather than a shortcut.
Most end-of-tenancy disputes come down to three of its articles: the deposit and its return, who pays for what repairs, and what happens if the tenant leaves early. Knowing which one a situation falls under turns the conversation from opinion into rule.
The LAU is not the whole picture in Catalonia: regional rules add to it, including deposit registration and rent limits in designated areas. Where they interact, that is a question for a lawyer rather than a guess.
