Sharing one lease: joint liability and what happens when someone leaves

Key rules

• Contract wording: A solidaria clause lets the landlord claim all the rent and damage from any one tenant.
• Leaving: You stay liable after moving out until the landlord releases you in writing.
• Replacement: A new tenant needs the landlord's written consent.
• Room contracts: Individual room contracts limit you to your own room's rent and share.

The short answer

If you sign one lease with other people, the landlord can often claim the whole rent and all the damage from any one of you. What decides this is the wording of your contract. Read it before you sign.

When you owe the whole amount

Spanish law does not assume that each tenant owes everything. By default, each of you would owe only your own share. But almost every shared lease says the tenants are liable "solidaria", and courts have also treated flatmates who share the use of a home as jointly liable.

If the clause is there, the landlord can pick one tenant and demand all the rent or all the repair costs. That tenant can then claim the other flatmates' shares back from them. The landlord does not care how you split the rent between you. The risk is that you pay first and chase the money afterwards.

So agree with your flatmates how the rent is split, and keep proof of who pays what.

What happens when someone leaves

Moving out does not end your duties. Unless the landlord agrees in writing to release you, you stay liable for rent and damage under the lease. The people who stay can also end up covering the full rent.

You have three ways to handle an exit:

• Release the leaver. Everyone, including the landlord, signs a novación that removes the person who is leaving. Ask for it in writing before the person moves out. The landlord may ask for a new guarantee from the people who stay.
• Bring in a replacement. A new tenant can take over only with the landlord's written consent. Without it, the leaver stays liable.
• End the lease together. After six months, the tenants can give notice as one party. One tenant alone usually cannot end the lease for the others, and courts commonly expect all tenants to give notice.

A tenant can leave after six months with 30 days' notice, but the others stay bound for the full term.

Unrelated flatmates

If you are not a couple or family, the single lease carries the biggest risk. You have no personal tie to the people you may end up paying for, and exit is hard.

The alternative is an individual contract for each room. Then you are liable only for your own room's rent and share, and you pay your own deposit. Exit and replacement are simpler. The catch is that room contracts are mostly governed by the contract terms and the Civil Code, not the housing rental law's tenant protections. Courts differ on whether that law covers room rentals, so have the contract reviewed.

With one lease, there is a single fianza of one month's rent. It is usually returned to all tenants together or to a named representative. Agree in advance who receives it and how it is split when someone leaves.

Couples

Do not assume anything from the fact that two tenants are partners. The same rules apply to them as to any co-tenants: the contract wording decides, and a partner who moves out stays liable until the landlord releases them. If one partner leaves, ask the landlord to sign a document removing them and keeping the other. If you rent as a couple, read the separate page on renting as a couple.

If you were the only tenant and your spouse or partner lives with you, they may be able to continue the lease if you abandon the home. They must notify the landlord.

Use the decision, timeline, checklist and warnings below to choose between a shared lease and room contracts and to plan an exit.

Choosing between options

Should you share one lease or sign individual room contracts?

• One lease for everyone: You trust your co-tenants. You get one housing rental with one deposit of one month's rent, but the landlord can usually claim the whole rent from any one of you, and leaving is hard.

• Individual room contracts: You are unrelated flatmates. You are only liable for your own room's rent and share and pay your own deposit, and changing tenants is simpler.

• Couple: ask the landlord to remove the leaver: One partner moves out. The remaining partner stays on the lease, possibly with a new guarantee, once the landlord signs an amendment. Until then, both stay liable.

If the contract says tenants are jointly liable (solidaria), the landlord can claim everything from any of you. Without that clause, each tenant is liable only for their own share.

Timeline and deadlines

• Agree with your co-tenants who is leaving and how: Before you tell the landlord anything

• Ask the landlord to sign a written release for the leaver, or to approve a replacement: Before the leaver moves out

• End the lease together with all tenants as one party: After the first 6 months, with 30 days' notice

• Stay liable for rent and damage if the landlord has not released you: Until the lease ends or the landlord agrees in writing

Check with your landlord or a housing adviser how exit works for your contract before you give notice.

Checklist

• Read your contract for a clause saying tenants are liable jointly (solidaria).

• Ask the landlord to sign a written release (novación) before anyone leaves, so the leaver is no longer liable.

• Get the landlord's written consent before you bring in a replacement tenant.

• Agree with all tenants to give notice together if the whole group is leaving.

• Agree with your flatmates how the rent is split, so you can claim back what you pay for others.

What to watch out for

• You can owe the whole rent and all the damage: Most shared leases make every tenant liable for everything (solidaria). The landlord can then claim the full rent or damage from any one of you, even if someone else caused it. Check your contract for this clause before signing. If you do not want it, ask for separate contracts per room.

• Leaving does not end your liability: If one tenant moves out without the landlord's written release, they stay liable under the lease. Those who stay may have to cover the full rent. Get the release in writing before the leaver goes.

• Unrelated flatmates carry the biggest risk: On one lease, you can be chased for a stranger's unpaid share, and a replacement needs the landlord's agreement. Without it, the leaver may stay liable. Only sign one lease with people you trust to pay, or choose individual room contracts.

Frequently asked questions

If I pay the whole rent for my flatmates, can I get the money back?

Yes. If the landlord claims the full amount from you, you can ask each of the others for their share. Keep proof of what you paid, because you will need it to claim.

My partner and I share a lease. Can I stay if my partner moves out?

Often yes. If your partner was the only tenant and you live there as their spouse or partner, you can continue the lease once the tenant has left. Tell the landlord that you are doing so.

Who gets the deposit back when we share one lease?

There is one legal deposit (fianza) of one month's rent, so it is usually returned to all tenants together or to a named representative. Agree with your flatmates in advance who receives it and how it is split.
