Let me say it straight: in Madrid, a lot of your paperwork starts with proving where you live, and a rental contract in your name is one way to show it. The padrón, which many later steps ask for, is the clearest example. I'm Peruvian, I live in Madrid, and I know the feeling of arriving with a long to-do list and no idea which item goes first. If you are renting, the contract is a good place to start. So this guide covers what happens before you sign: what landlords ask for, how the deposit works and which fees are not meant to be yours. I'm not a lawyer, and this isn't legal advice. It's the process, explained plainly, with official sources.
A lot of what you need after arriving hangs off proving your address. To register at your address you need to show that you live there, and a contract in your name is one of the documents that can prove it. Our guide to getting your empadronamiento in Madrid explains the next step. If the contract isn't in your name, there is a route through the owner's authorisation, which we cover in Spanish here.
If you are renting, it makes sense to sort out the contract before your padrón appointment. So it's worth getting the rental part right, because fixing a bad contract later is slow and tiring.
The Comunidad de Madrid's rental guide lists what the contract itself should state: who the owner and the tenant are, which home it is, how long it lasts, the rent and how you pay it, the deposit, and who pays which expenses. It doesn't give a list of documents a landlord may request from you.
In practice, press and sector sites say landlords commonly ask for recent payslips, an employment contract and sometimes references. Newcomers often can't offer a Spanish payslip yet, so be ready to explain your situation and show what you do have, such as a foreign contract.
Here's my opinion, and it's only that: ask what each document is for before you send it. Data protection rules apply to landlords and agencies too. Consumer-focused sites suggest hiding what isn't needed, like the bank account number on a payslip, and sharing documents through a secure channel instead of a random chat. If you're unsure about a request, ask a professional.
The fianza is the deposit you hand over when you sign. For a home you live in, the Comunidad de Madrid says it equals one month's rent.
Here's the part newcomers often miss. The landlord isn't supposed to keep that money. In the Comunidad de Madrid, the landlord deposits it with the Agencia de Vivienda Social. The official procedure page says this is mandatory for the landlord, that the deposit earns no interest, and it gives a deadline of 30 days, although it describes them in slightly different ways (in places as 30 working days, counted from signing or from the day after the contract or its entry into force), so ask for the receipt rather than doing the maths.
Ask your landlord for proof that the deposit was filed. If you never get a receipt, the Agencia de Vivienda Social has a request tenants can use to get proof of the deposit, and you will need a copy of your lease. At the end of the contract the deposit comes back to you, minus the cost of damage beyond normal use, according to the Comunidad's guide.
This is the one that surprises people. According to the Comunidad de Madrid's guide, property management and contract formalisation costs are the landlord's responsibility, and they can't be passed on to you directly or under another name. Optional services can be charged only if you ask for them in writing after being clearly told they are voluntary and what they cost.
So if an agency invoice arrives with a line for paperwork or contract preparation, stop and ask what it is and why it's yours. I'd love to say it's always black and white. It isn't. If a clause or a charge looks off, a lawyer can read your actual contract, and that is worth doing before you pay, not after.
Besides the deposit, a landlord may ask for an additional guarantee, such as a bank guarantee. The Comunidad's guide says that for habitual-residence contracts of up to five years (seven if the landlord is a company) the additional guarantee can't exceed two months' rent. It also says a landlord can't require you to take out non-payment insurance for the owner's benefit.
Separately, the Ley de Arrendamientos Urbanos says the landlord can never demand advance payment of more than one month's rent. That limit is about rent paid in advance: the deposit and any lawful additional guarantee are separate amounts.
Check a few simple things. Your name and the owner's name are correct. The rent and the payment method are written down. The deposit is stated. Then look at who pays what: community fees and other building costs can be assigned to the tenant only by written agreement, while individually metered supplies such as electricity, water and gas are the tenant's.
Look at how the rent can be updated too. The Comunidad's guide says an update only happens if the contract expressly provides for it, once a year. And the same page says a tenant can leave after six months with at least 30 days' notice.
Heads up, because this matters. The Comunidad de Madrid's rental guide says it reflects Real Decreto-ley 29/2026, in force since 8 October 2026 but still pending parliamentary validation. A second decree, 28/2026, which changes contract duration and extensions, is expected to take effect on 15 November 2026 and is also pending validation. The BOE's consolidated text of the LAU also notes that some 2026 amendments were annulled or are pending.
In short, details on duration and rent updates may change. Check the official page or ask a professional right before you sign.
Keep a copy of the signed contract, the deposit receipt and your payment proofs. Then move on to registering your address, opening a bank account and sorting out your NIE if you don't have one yet.
