Bank account in joint ownership: complete guide 2026

Joint ownership (indivision) creates significant financial constraints for heirs and co-owners. Between the impossibility of acting alone and the need to bring together all the joint owners for day-to-day management acts, opening and managing a bank account in joint ownership quickly becomes a legal and practical headache. This guide examines the applicable rules, the banking solutions available and the strategies for avoiding deadlock.

Definition and legal framework of the bank account in joint ownership

The principle of inherited and property joint ownership

Joint ownership arises automatically on a person's death over all of his assets, creating a temporary legal situation in which several persons together hold rights over the same estate. Article 815 of the French Civil Code lays down the principle: "No one may be compelled to remain in joint ownership", but for as long as it lasts, it imposes strict rules of collective management. What happens to the deceased's account and the steps incumbent on the heirs are examined in our article on the bank account in joint ownership after death.

In property matters, joint ownership frequently concerns the deceased's main residence, rental properties or shares in an SCI (French property holding company). The joint owners become owners in joint ownership, with rights in the joint ownership expressed as a fraction (1/2, 1/3, 1/4, etc.) but without any exclusive right over a specific part of the property.

Why a bank account in joint ownership is needed

The management of joint ownership requires a dedicated account to be opened for several reasons:

• Centralising common receipts (rents, sale of the deceased's furniture, insurance reimbursements)
• Paying the costs of maintaining and preserving the jointly owned property
• Ensuring financial transparency between joint owners
• Keeping the statement of income received and expenses incurred on behalf of the joint ownership, which Article 815-8 of the French Civil Code makes available to the joint owners

An heir's personal account cannot legally receive the funds of the joint ownership without creating a risk of commingling of assets and of a liability action by the other joint owners.

Opening the bank account in joint ownership and formalities

Prerequisites for opening

Opening a bank account in joint ownership requires several documents to be gathered:

For inherited joint ownership:

• Acte de notoriété (notarial certificate of heirship) or deed of devolution of the estate drawn up by a notary
• Proof of identity and address of all the joint owners
• Tax certificate of filing of the estate tax return (if required)

For joint ownership of real property:

• Title deed (deed of sale, gift, etc.) mentioning the joint ownership
• Up-to-date civil status of all the joint owners
• Proof of legal representation for minors

The bank systematically checks the legal capacity of each joint owner and may refuse to open the account if a protected adult is among them without the authorisation of the guardianship judge (juge des tutelles).

Operating terms of the account

The account in joint ownership operates under two main regimes:

Mandatory joint signature: All the joint owners must sign each transaction. This formula, the most secure legally, becomes impractical as soon as the joint ownership has more than three members or where they live far apart.

Management mandate: Article 815-3 of the French Civil Code allows the joint owners holding at least two thirds of the joint rights to give one or more of the joint owners, or a third party, a general mandate of administration. Failing that, the president of the judicial court (tribunal judiciaire) may appoint a joint owner as administrator (Article 815-6). The agent then has the powers necessary for acts of administration, including sole signature on the bank account, but not for acts of disposal.

Banking limits and restrictions

Banks generally apply specific restrictions to accounts in joint ownership:

• Reduced or prohibited overdraft limit
• No individual bank card issued
• Large transfers subject to approval by the bank
• Automatic closure in the event of documented disagreement between joint owners

These precautions are intended to protect the bank from conflicts between joint owners and from subsequent liability actions.

Day-to-day management and powers of the joint owners

Acts of ordinary administration

Article 815-3 of the French Civil Code subjects acts of administration relating to the jointly owned property to a majority of the joint owners holding at least two thirds of the joint rights, who must inform the others; a joint owner may act alone only for measures necessary for the preservation of the jointly owned property (Article 815-2). As regards the bank account, the following fall within administration:

• Payment of ordinary charges (property tax, co-ownership property manager (syndic))
• Payment of invoices for maintenance and minor repairs
• Collection of rents and security deposits
• Transfers between accounts of the joint ownership

These transactions therefore require the agreement of the joint owners holding at least two thirds of the joint rights, or a mandate. A joint owner who takes over the management of the jointly owned property with the knowledge of the others and without objection from them is deemed to have received a tacit mandate covering acts of administration (Article 815-3, last paragraph); he incurs liability towards the other joint owners if he exceeds his powers or acts solely in his own interest.

Acts of disposal requiring unanimity

Certain transactions on the account require the unanimous agreement of the joint owners:

• Taking out credit or an overdraft facility
• Surety or guarantee given over the funds of the joint ownership
• Investing cash in risky products (shares, dynamic UCITS (OPCVM))
• Closing the account and distributing the balance

Breach of this unanimity rule exposes the defaulting joint owner to damages.

Monitoring and transparency

Each joint owner has a right to information on the management of the joint ownership, including:

• Free consultation of account statements
• Disclosure of supporting documents for all transactions
• Annual rendering of accounts if a manager has been appointed

Case law accepts that a joint owner may apply directly to the bank to obtain this information, without going through the manager or the other joint owners.

Practical solutions for avoiding deadlock

Appointing a sole manager

Appointing a manager is often the most pragmatic solution for smooth management of the joint ownership. This appointment may result from:

• A general mandate of administration given by the joint owners holding at least two thirds of the joint rights (Article 815-3 of the French Civil Code), or a joint ownership agreement (convention d'indivision) (Article 815-1 of the French Civil Code)
• A decision of the president of the judicial court, who may appoint a joint owner as administrator or appoint a sequestrator (Article 815-6 of the French Civil Code)
• A testamentary clause of the deceased (for inherited joint ownership)

The manager then has extended powers: sole signature on the account, collection of income, payment of charges and maintenance expenses. He remains required to render accounts annually and may not perform acts of disposal without unanimity.

Deposit account with several agents

Some banks offer an account in joint ownership with several designated agents, each able to act within a defined amount. This formula suits family joint ownership where several persons (adult children, surviving spouse) wish to retain direct control.

The agent acts in the name and on behalf of the joint ownership, within the limits of his mandate. The other joint owners may revoke this mandate at any time, which requires careful handling of family relations.

Separating flows by type

A recommended practice is to open several accounts according to the type of flows:

Receipts account: dedicated to rents, dividends and income from the jointly owned property Charges account: reserved for recurring expenses (taxes, insurance, maintenance) Project account: for exceptional transactions (works, sale)

This organisation makes accounting follow-up easier and limits the risk of confusion, in particular when rendering accounts or on the final division.

Special cases and complex situations

Joint ownership with minors or protected adults

The presence of a minor or a protected adult among the joint owners significantly complicates the management of the joint ownership. Former Article 389-5 of the French Civil Code was repealed by Ordinance No. 2015-1288 of 15 October 2015: the legal administrator of a minor now needs the prior authorisation of the guardianship judge only for the acts listed in Article 387-1 of the French Civil Code, which include:

• Borrowing in the minor's name
• Waiving a right on behalf of the minor, or entering into a settlement or an arbitration agreement in his name
• Accepting unconditionally an inheritance passing to the minor

The legal administrator performs the other acts alone, but is required to manage the minor's property with prudent, diligent and informed care, solely in the minor's interest (Article 385 of the French Civil Code). For a protected adult, the powers of the guardian or curator depend on the measure ordered.

International joint ownership

Where some joint owners live abroad, opening and managing the account runs into several difficulties:

Banking regulations: Anti-money laundering obligations require the identity and address of all holders, including non-residents, to be verified.

Taxation: Income from the account may have to be declared in several countries, requiring complex tax coordination.

Proxies (procurations): A joint owner abroad may give a proxy to a French resident, but that proxy must comply with the legal formalities of the country of residence and be apostilled.

Disagreement between joint owners

Conflicts between joint owners quickly paralyse management of the account. Faced with this situation, several solutions exist:

Interim payment: The president of the judicial court may authorise a joint owner to collect from debtors of the joint ownership or from depositaries of jointly owned funds an advance to meet urgent needs, prescribing if necessary the conditions for its use (Article 815-6 of the French Civil Code).

Appointment of an administrator: Article 815-6 of the French Civil Code allows the president of the judicial court to appoint a joint owner as administrator or to appoint a sequestrator. Article 815-5 further allows the court to authorise a joint owner to carry out alone an act for which the consent of another joint owner would be necessary, if the latter's refusal jeopardises the common interest.

Court-ordered sale (licitation): As a last resort, the forced sale of the jointly owned property makes it possible to exit the joint ownership definitively and to distribute the price between the former joint owners. The various exit routes open to a joint owner are presented in our article on the principle that no one is required to remain in joint ownership.

Taxation and reporting obligations

Taxation of income from the account

Income generated by the funds in the bank account in joint ownership (interest, capital gains on the sale of securities) is taxable in the name of each joint owner, in proportion to his rights in the joint ownership.

The institution paying income from movable capital declares to the tax authorities the identity of the beneficiaries and the amount of the income, and sends them a copy (Article 242 ter of the French General Tax Code, single tax statement or IFU). Each joint owner then reports his share on his personal return.

Return for the joint ownership

If the joint ownership generates property or business income, it may be required to file a specific return (form No. 2072) in the name of the joint ownership. This obligation mainly concerns:

• Joint ownerships holding rental properties
• Joint ownerships continuing a commercial activity of the deceased
• Joint ownerships holding significant interests in companies

Failure to file exposes the joint ownership to tax penalties for which all the joint owners are jointly and severally liable.

Tracking movements for the estate

For inherited joint ownership, all movements on the account must be kept with a view to the final settlement of the estate. These supporting documents are used to:

• Establish the net assets of the estate on division
• Calculate the amounts to be brought back and compensation (récompenses) between heirs
• Justify the expenses incurred for the preservation of the property

Since division may always be requested, unless it has been stayed by judgment or agreement (Article 815 of the French Civil Code), no limitation period applies to the action for division: bank documents must be kept until final division. However, claims relating to the fruits and income of the jointly owned property are no longer admissible more than five years after the date on which they were received or could have been received (Article 815-10).

Exit from joint ownership and winding-up of the account

Amicable division and distribution of funds

Amicable division, formalised by notarial deed, ends the joint ownership and automatically entails the closure of the bank account in joint ownership. The balance is distributed in one of several ways:

Proportional distribution: Each joint owner receives a sum proportional to his rights in the joint ownership, after deduction of common debts and charges.

Preferential allocation with compensation: A joint owner may receive all the funds in return for paying an equalisation payment (soulte) to the others.

Carry-over to the sale price: If the joint ownership concerns a property that has been sold, the funds may be added to the sale price for an overall distribution.

Court-ordered division and escrow

In the event of disagreement on the terms of division, the court often orders the funds to be deposited with the Caisse des dépôts et consignations (French public deposit and consignment fund). This protective measure prevents the funds from being dissipated during the proceedings.

The notary responsible for the court-ordered division is then instructed to settle the claims and debts of the joint ownership before final distribution. This procedure, heavier and more costly, may extend over several years. The rights and obligations of each joint owner at the division stage are developed separately in our article on the division of joint ownership.

Prescription and unclaimed funds

If some joint owners cannot be found at the time of division, their shares may be deposited with the Caisse des dépôts et consignations. The deposited sums pass to the State after a period of thirty years without any transaction or claim on the account (Article L. 518-24 of the French Monetary and Financial Code).

This rule encourages an active search for all persons entitled before proceeding with the division, even if this delays the winding-up of the joint ownership.

Frequently asked questions

Can a bank account in joint ownership be opened without a notary?

Yes, for de facto joint ownership (property bought jointly by unmarried partners, for example). On the other hand, inherited joint ownership requires an acte de notoriété or a deed of devolution of the estate drawn up by a notary, which is mandatory to prove heir status to the bank.

Can a single joint owner withdraw money from the account?

Only if he has received a mandate or has been appointed administrator, or for measures necessary for the preservation of the jointly owned property, for which he may use the funds of the joint ownership that he holds (Article 815-2 of the French Civil Code). Acts of administration, such as payment of current charges, require a two-thirds majority of the joint rights (Article 815-3). Any other withdrawal gives rise to his liability.

What happens if a joint owner refuses to sign?

If unanimity is required (investment, credit, act of disposal), the refusal of one joint owner blocks the transaction. The court may, however, authorise a joint owner to carry out the act alone if that refusal jeopardises the common interest (Article 815-5 of the French Civil Code), the president of the judicial court may order the urgent measures required by the common interest (Article 815-6), and each joint owner may request division. For acts of administration, a two-thirds majority of the joint rights is sufficient (Article 815-3).

Does the account in joint ownership give rise to specific charges?

Banks generally apply their standard rates, but some charge higher management fees to offset the administrative complexity. It is advisable to negotiate these terms when the account is opened, in particular for large or long-lasting joint ownerships.

How long can a joint ownership with a bank account last?

No statutory duration is imposed. Joint ownership may last several decades if the joint owners do not request division. However, Article 815 of the French Civil Code guarantees each person the right to leave the joint ownership at any time, unless otherwise agreed for a period limited to five years.

Can a creditor seize the funds in the account in joint ownership?

Only creditors of the joint ownership itself (common charges, works, etc.) may seize the account directly. A personal creditor of a joint owner must first have his claim established, then apply for division in order to seize his debtor's share.

How should overdraft interest and bank charges be allocated at the end of the joint ownership?

The operating costs of the account are common charges of the joint ownership, deductible from the assets to be divided. They are therefore borne by all the joint owners in proportion to their rights, unless one of them has caused exceptional costs through his own fault (unauthorised overdraft, payment incidents).

The management of joint ownership through a dedicated bank account remains an unavoidable but technically demanding step. The key lies in prior organisation: appointing a competent manager, clearly defining each person's powers and anticipating deadlock situations. Given the growing complexity of banking and tax obligations, it is advisable to have the arrangement validated by a notary as soon as the account is opened.
