Choosing joint or separate money in Spain

Terms used

• Cuenta conjunta — The cuenta conjunta is a bank account with two or more holders who are all party to the contract.
• Titulares — The titulares are the holders named in a bank contract, with rights over the account and liability for it.
• Mancomunada — A mancomunada account needs all holders to sign together for any withdrawal or payment.
• Autorizado — An autorizado is a person allowed to operate your account without being a holder or owner.
• Modelo 720 — Modelo 720 is the tax declaration of assets held abroad, filed by Spanish tax residents above set thresholds.

Key rules

• Joint liability: Joint account holders are normally each liable to the bank for the whole of any overdraft or debt on the account.
• Ownership between you: The balance is presumed to be split equally, unless one of you can prove you alone paid in the money.
• Autorizado: An autorizado can operate the account but owns nothing and cannot close it or change the contract.
• Partner without income: A partner who does not earn should have at least a personal account or card.

The short answer

Most couples do well with a hybrid: one joint account for shared bills, and a personal account each. It is not the only choice. Pick by how much you value simplicity, independence and protection, once you know how Spanish joint accounts work.

The comparison below sets the three systems side by side.

How a Spanish joint account works

A joint account (cuenta conjunta) has two or more titulares, the holders named in the bank contract. Each holder has rights over the account and also responsibility for it.

• "O" (indistinct) accounts. This is the usual arrangement. Any one holder can withdraw, pay or give instructions alone.
• "Y" (mancomunada) accounts. All holders must sign together for any withdrawal or payment.

Check which type you are opening, because it decides whether one of you can act alone.

Who owns the money, and who owes the bank

Joint account holders are normally each liable to the bank for the whole of any overdraft or debt on the account. The bank can claim the full sum from either of you, whatever each of you put in.

Between the two of you, the balance is presumed to be owned in equal shares. If one of you can prove they alone paid in the money, that person can recover it. So if you put in most of the funds, keep records of it.

On an "o" account, either of you can legally take the whole balance as far as the bank is concerned. If one takes more than their share, they may owe the other the difference. If you are married, your matrimonial regime also affects who owns what.

Giving a partner access without making them a holder

An autorizado is an authorised person on your account. They can usually withdraw or operate, but they cannot close the account, change the contract or add holders, and they own nothing. You can revoke the authorisation at any time, and it ends if you die. The exact powers depend on the bank's form, so read it before signing.

This suits a partner who needs card access but whom you do not want exposed to the account's debts.

Common set-ups

1. Joint bills account plus personal accounts. Rent, utilities and food come from the joint account. You fund it equally or in proportion to income. Each keeps a personal account for private spending. It is transparent and fair, but you must agree contributions, and both of you carry joint liability and seizure risk.
2. Everything pooled. One shared pot. It is simple, but gives each of you less autonomy.
3. Fully separate. You split costs by percentage or take turns paying bills. You stay independent, but a partner with no income can end up dependent.
4. One partner pays the bills, the other covers other costs.

If one of you does not earn, make sure that partner has at least a personal account or card.

Fitting in your home-country accounts

You do not have to close them. Many people keep them for family, savings or a return home. Two points matter:

• Decide which account pays Spanish bills. Paying rent and utilities from a Spanish account is simpler and avoids repeated transfer fees.
• If you are a Spanish tax resident, foreign accounts may need reporting. A joint account abroad counts for each resident holder at their ownership percentage. The timeline below sets out the Modelo 720 steps and thresholds.

Set a routine

Agree these things before the first rent payment:

• how much each of you pays into the joint account, and how often
• who can spend what without asking
• who checks the account, and how often
• what happens if one of you stops earning

Review it after a few months. A system that worked in your home country may not suit life in Spain.

Joint, separate and hybrid accounts side by side

Quick answer

A joint account is the easiest to run but the riskiest. Each holder is normally liable to the bank for the whole of any overdraft or debt on the account. Separate accounts keep each person's money and debts apart. A hybrid setup, with one joint account for shared bills and separate accounts for everything else, usually gives the best balance.

Side by side

What joint holding means in practice

Equal shares are only a presumption. If you put in most of the money, you can prove it and recover your share. You will need evidence, such as payslips or transfer records. Under the "o" setup, any holder can legally take out the whole balance as far as the bank is concerned. Between you, a holder who takes more than their share may have to repay the other.

An autorizado is not a holder. They have only the powers you give them, usually to withdraw or operate the account. They cannot close the account, change the contract or add holders. They own nothing in the account, and you can remove their authority at any time. It ends if you die.

Seizure. If a creditor of one holder gets a seizure order, the amount kept is normally limited to that holder's share. For two holders, that is half. In practice, though, the bank may freeze the whole balance first. The other holder then has to prove the funds are theirs alone and ask for their release. Seizures ordered by the tax authority may be applied more broadly. A minimum amount of salary and pension money is protected from seizure.

Married couples. Who owns what also depends on your matrimonial regime. Under a community-of-property regime (gananciales), joint funds can in some cases answer for one spouse's debts. If you are married, ask a notary or lawyer how your regime affects the account.

Which to choose

• Choose joint if you trust each other fully, have similar incomes and want the least admin.
• Choose separate if either of you has debts, runs a business, is self-employed or has very different finances.
• Choose hybrid if you want easy shared bills without putting all your money at risk. This suits most couples and flatmates.

Before opening any joint account, ask the bank whether it will be "o" or "y". Also ask whether overdrafts are allowed, and switch overdrafts off if you can.

Timeline and deadlines

• Add up the value of your home-country accounts, including your share of joint ones: on 31 December each year

• File Modelo 720, the declaration of assets abroad, if the bank accounts together are worth more than 50,000 euros: between 1 January and 31 March of the following year

• File again only if the accounts category has risen by more than 20,000 euros since your last filing: in later years, in the same 1 January to 31 March window

What to watch out for

• Home-country accounts may need reporting in Spain: If you are a Spanish tax resident and your accounts abroad are worth more than 50,000 euros at 31 December, you must file Modelo 720, the declaration of assets abroad. This applies to holders, authorised persons and beneficial owners. A missing or late filing now brings fixed fines. Add up your accounts, including your share of joint ones, each December and file between 1 January and 31 March.

• A joint bills account puts both of you at risk of seizure: Money in a joint account can be seized because of a debt of either holder, so private savings left there are exposed. Keep only the money for shared bills in the joint account and hold the rest in personal accounts.

• Fully separate accounts can leave a partner without income dependent: If one partner earns nothing, separate accounts mean they have no money of their own to use. Make sure that partner has at least a personal account or card, and agree how much goes into it each month.

Frequently asked questions

What can an autorizado do on a Spanish account?

An autorizado is an authorised person who can usually withdraw or operate the account, but is not a holder and owns nothing in it. They cannot close the account, change the contract or add holders. The holder can cancel the authorisation at any time, and it ends when the holder dies.

Can one holder withdraw the whole balance of a joint account alone?

Yes, in the usual arrangement (marked "o" in the contract) any single holder can withdraw the whole balance alone, but they may owe the other holder their share back. If the contract says "y" (mancomunada), all holders must sign together for any withdrawal or payment.

If I put in most of the money, do I still own only half of a joint account?

Between the holders, the balance is presumed to be owned in equal shares, so you start with half. If you can prove the money was yours alone, you can recover it. For spouses, the matrimonial regime also affects who owns what.

Do I report a joint account in my home country in Spain?

Yes, if you are a Spanish tax resident and your foreign accounts together are worth more than 50,000 euros at 31 December, you file Modelo 720, the declaration of assets abroad. Each resident holder reports their own share of a joint account at the percentage they own.
