Deposits from a joint or third-party account: why it complicates things

A transfer that does not leave your personal account almost always triggers questions: the professional sees money arriving from a third party and must be able to connect that third party to the transaction. A deposit coming from a joint account, a parent’s account or a company is by no means forbidden, but it steps outside the expected reading pattern: buyer, account, contribution. The good news is that every situation has its regularisation, easy to run when you anticipate it with the notaire and the bank. This guide describes the typical cases, the documents that unlock them and the timetable to respect. It builds on the journal’s reference guide to opening and keeping a French bank account.

Why does a transfer from another account trigger checks?

Two logics overlap. The first is coherence: client-knowledge checks tie operations to the account holder. When the payer is neither the borrower nor the buyer, the professional must document the link between the two: who this third party is, why they are paying, what the legal basis of the payment is. Without that link in writing, the flow resembles unexplained money moving in circles, and processing is suspended.

The second is the fight against money laundering: funds coming from a third party are among the configurations calling for documented vigilance, precisely because they can mask an undeclared gift, an informal loan or a hidden asset. Here again, this is not suspicion towards you, but a process satisfied by simple documents: a letter, a deed, a corporate resolution, according to the case.

Let us define who counts as a third party: anyone who is not the buyer personally, spouse included if the account is not the buyer’s own, parents, children, associates, companies. Emotional closeness changes nothing in the mechanics of the checks: the closer the payer, the simpler the document founding the payment, and that is the only difference.

Keep the practical rule in mind: the lender and the notaire want every euro of the contribution to leave an account in the buyer’s name, or the departure from that rule to be justified by a document. Everything else in this article consists in regularising that departure.

Which typical situations complicate the contribution?

Three configurations recur in non-resident files.

The joint account with a spouse who is not borrowing. Both partners’ savings sit in a common account; only one of them is buying and borrowing, and the contribution would leave the joint account. The professional then sees a transfer in which one of the co-holders plays no part in the purchase, and wonders about that co-holder’s consent.

The gift received through a parent’s account. The parents have helped, and the help was first paid into their own account, or still sits there, before being passed on at purchase time. Here the flow skips two steps: from the donor’s account to yours, then to the notaire, and each skip needs its legal basis.

Company funds. The contribution would be paid by a company, a holding or a trading company, in which you are a shareholder or a manager. The professional must then understand the corporate resolution authorising the payment and check that the operation respects the company’s form: a more technical file, perfectly manageable, but one that is prepared.

The informal help of a relative. A brother lends a sum, a friend fronts a deposit: the flow leaves an account with no role in the purchase and no known legal title. Without writing, this de facto loan meets the same questions as an undocumented gift, with one further document to produce: the loan agreement showing a repayable debt, not a gift disguised as a loan.

How do you bring the contribution back into conformity?

Each situation has its regularisation, to be carried out in order and in writing.

• Joint account case: ask the co-holder for a signed, dated letter stating their capacity as co-holder, the amount involved and their consent to the funds being used for the acquisition; or have the funds transferred to your personal account beforehand, and let them rest there for as long as the institution considers sufficient.
• Gift case: have a gift deed in proper form drawn up by a legal professional, naming donor, recipient, amount and date; if the help was paid long ago, a deed regularising it after the fact remains possible, provided it is established before the funding file is examined.
• Company funds case: produce the corporate resolution authorising the payment, according to the company’s form, minutes of the competent body or manager’s decision, together with an up-to-date extract; specify the nature of the operation, advance on account, distribution or otherwise, so the professional can record the flow in the right category.

In every case, the method remains that of the guide on proof of source of funds: document the money’s complete journey, from its point of origin to the account that pays the notaire, with documents that answer one another.

The table of situations, requests and regularisations

Situation	What the professional asks for	Regularisation
Contribution from a joint account	The consent of the co-holder who is not buying	Signed letter from the co-holder, or prior transfer to your personal account
Gift paid by a parent	The legal basis of the payment	Gift deed in proper form, donor identity, statements of the journey
Help already paid, with no deed	The reconstitution of the flow	Regularisation through a deed established before the file is examined
Payment from a company	The corporate resolution authorising it	Decision of the competent body, up-to-date extract, qualification of the operation
Direct transfer from a third party to the notaire	The explanation of the third-party payer	To be avoided without the notaire’s and the lender’s prior written agreement

How do you anticipate with the notaire and the bank before the day itself?

Regularisation plays out in the timetable, not in improvisation. First rule: announce. Flag the configuration of your contribution as soon as the loan is studied and at the first contact with the notaire, even while the funds are still untouched. Each professional will tell you what they expect, and you will avoid discovering their requirements in signature week.

Second rule: let the funds rest. The lending institution looks at the contribution’s origin, but also at how long it has sat in your account: a contribution stable across several statements reads as savings, a contribution that arrived yesterday reads as a question. Plan the transfers accordingly.

Third rule: align everyone. The co-holder’s letter, the gift deed, the corporate resolution must reach the bank, the notaire and, where relevant, the currency provider in identical versions.

An ordered timetable, to fix ideas: as soon as the offer is made, announce the configuration to the professionals concerned; at loan study, produce the co-holder’s letter or the draft deed; before the preliminary contract, have the funds transferred to your personal account; between contract and signature, let the funds rest and gather the statements; in signature week, send the complete file, identical for each. This sequencing fits a normal purchase timetable, provided it is launched from the start, never in reverse. If your situation also touches configurations under enhanced scrutiny, our article on enhanced scrutiny and delicate situations details the attitude to adopt.

A contribution from elsewhere is never a definitive block: it is a document to produce and a timetable to respect. If your configuration is out of the ordinary, the personal study offered by French Realty identifies, with your dedicated contact, the documents expected, then coordinates the regularisation with the notaire and the lending institution.
