Joint Bank Account Rules in the UAE: Signing Mandates, Death and Divorce

Most joint accounts in the UAE are opened on a good day — a marriage, a new home, a business partnership — and the rules that actually govern them only surface on a bad one: a death in the family, a divorce filing, a debt collector, or a co-holder who quietly emptied the balance. Every one of those moments is already written into the law and into the mandate you signed at the counter. Reading both before the bad day costs nothing.

Direct answer. Joint bank accounts in the UAE are governed by Article (379) of Federal Decree-Law No. 50 of 2022, the Commercial Transactions Law (see the official English translation on the UAE Government portal). The holders' shares are presumed equal unless a different split is agreed and recorded with the bank, and day-to-day withdrawals follow whatever signing mandate the holders agreed — either-to-sign or joint signatures. When one holder dies or loses legal capacity, the surviving holders must notify the bank within ten days, and the bank blocks the deceased's share of the balance until a successor is appointed. There is no automatic right of survivorship: the deceased's share goes into the estate, not to the surviving co-holder.

The law that governs joint accounts in the UAE

One article of the federal Commercial Transactions Law does most of the work, and everything else is contract.

The controlling instrument is Federal Decree-Law No. 50 of 2022 on Commercial Transactions. Its Article (379) permits a bank to open a joint account — a deposit account or any other account — between two or more persons "with equal shares among them, unless otherwise agreed and recorded with the bank". That single clause carries three practical consequences:

• Equality is the default. If you and a co-holder never told the bank otherwise, the law treats the balance as half yours and half theirs — whoever actually deposited the money.
• A different split must be recorded with the bank. An informal understanding between holders, or an arrangement written only in a side agreement the bank never saw, does not displace the presumption at the bank counter.
• The rest is your mandate. Beyond the statutory floor, the account operates on the terms the holders signed — which is why the either-to-sign versus both-to-sign choice below matters more than most people realise on the day they open the account.

One historical note, because older articles still circulate online: joint accounts used to sit in Federal Law No. 18 of 1993, the previous Commercial Transactions Law. That law was repealed and replaced by Federal Decree-Law No. 50 of 2022, so the current citation is Article (379) of the 2022 law. The substance travelled across largely intact, but always read the current text.

Either-to-sign vs both-to-sign: the mandate decides everything

The signing mandate — not the law — controls who can move money on an ordinary day.

Article (379)(1) sets the opening formalities: a joint account is opened by all of its owners together, or by one person holding a power of attorney from the other owners that has been duly authenticated by a competent official authority. From then on, "withdrawals from such account shall be conducted according to the agreement of the account owners". In practice banks offer two broad operating modes:

• Either to sign (single signature). Any holder can withdraw, transfer, or close positions alone, usually up to the full balance. This is the convenient mode — and the dangerous one. If the relationship breaks down, either holder can lawfully empty the account before the other finds out, because the bank is simply executing the mandate both of you signed.
• Both to sign (joint signatures). Every instruction needs all holders' signatures or approvals. Nothing moves without agreement, which protects each holder from the other — at the price of gridlock if one holder is travelling, uncooperative, or incapacitated.

Points that catch people out:

• The mandate is a bank contract. Changing it — from either-to-sign to both-to-sign, or removing a holder — generally requires the consent of the holders in accordance with the account terms; one holder cannot usually rewrite it alone, though many banks will accept one holder's instruction to suspend single-signature operation while a dispute is resolved. Each bank's procedure differs; confirm the exact mechanics with your bank before you rely on them.
• Debit cards and online banking access are extensions of the mandate. An either-to-sign account with two cards is two independent taps into the same pool.
• Cheque books, overdrafts and linked products follow the account terms, and liability for them is typically joint — a point to check in the account agreement before signing, not after.

What happens when a joint account holder dies

The law imposes a ten-day notification duty and freezes the deceased's share — and in practice banks often restrict more than that.

Article (379)(4) of the Commercial Transactions Law is explicit. Upon the death or loss of legal capacity of a joint account holder, the other holders must notify the bank within ten days of the date of death or incapacity. From the date it is notified, the bank suspends withdrawals from the joint account "within the limits of such person's share of the account balance on the date of his death or lack of capacity" — and no withdrawal may be made from the deceased's share until a successor is appointed.

Read that carefully, because it corrects two widespread assumptions:

• There is no survivorship. A surviving spouse or partner does not inherit the account by being named on it. The deceased's share — half, by default — belongs to the estate and is distributed under the applicable succession framework, not under the bank mandate.
• The freeze is on the share, not automatically the whole account. The statute requires the bank to block the deceased's portion. In practice, many banks restrict the entire account until they see succession documents, particularly where the shares were never separately recorded — how far a given bank goes is a matter of its own policy and its reading of the estate risk, and it can differ from bank to bank; confirm the treatment with the bank concerned or a licensed UAE lawyer.

Releasing the blocked share requires the succession paperwork the courts issue — typically a court-issued succession certificate identifying the heirs, or probate of a registered will. Succession itself is governed by the Personal Status Law, Federal Decree-Law No. 41 of 2024, which came into force on 15 April 2025, and the route differs depending on whether the deceased left a registered will. If you hold assets in the UAE, registering a will is the single most effective way to shorten this stage — our guide to registering a will at the ADJD in Abu Dhabi walks through one of the main routes, and DIFC Wills registration serves a similar function for eligible testators.

Two adjacent points worth knowing. First, the ten-day duty sits on the surviving holders — quietly continuing to operate an either-to-sign account after a co-holder's death is not a loophole; it is a breach of the statutory duty. Second, money that arrives after death, such as a final salary or end-of-service gratuity, belongs to the estate and follows the succession process, whatever account it lands in.

One holder's debts: seizure and set-off

A creditor of one holder can reach that holder's share — and only that share — but the whole account feels it.

Article (379)(2) deals with attachment. Where a court-ordered seizure is served against one co-holder, it applies to that person's share of the balance as at the day the bank is served with the seizure notice. The bank must then suspend withdrawals from the joint account up to the amount of the seized share, and must inform the co-holders or their representatives of the seizure within five business days of its imposition.

Article (379)(3) deals with set-off: when a bank wants to offset one holder's debts against accounts it holds, it may bring the joint account into that set-off only with the written consent of the other co-holders. In other words, your co-holder's personal loan default does not silently drain your half — but a court seizure against them will immobilise their half, and an either-to-sign mandate will not unfreeze it.

Practical consequences:

• Sharing an account with someone in financial difficulty exposes the account to freezes even though your own share is legally protected. If a co-holder is heading into default, read our companion guide on loan deferral and your rights when you cannot pay — early restructuring is usually cheaper than a seizure.
• Because shares are presumed equal, a seizure against a co-holder can immobilise half of a balance you funded entirely — unless a different split was recorded with the bank. Recording real contributions is not paperwork for its own sake; it is what the presumption yields to.

Joint accounts and divorce

The equal-shares presumption cuts both ways in a divorce, and the mandate decides what happens while the case is pending.

The UAE does not operate an automatic community-property regime: in principle each spouse keeps the assets held in their own name, and a joint account is the deliberate exception the couple created. When a marriage ends, three layers interact:

• The statutory presumption. Unless a different split was agreed and recorded with the bank, the law treats the joint balance as owned in equal shares. A spouse who claims the real contribution was different carries the burden of proving it — with salary transfers, deposit records and statements.
• The mandate. On an either-to-sign account, either spouse can lawfully withdraw the balance while proceedings are pending, and the bank will not stop them. That is the practical reason family lawyers move quickly on joint accounts: the remedy after the fact is a claim against the withdrawing spouse, which is slower and less certain than not losing the money in the first place.
• The court. A court seised of a divorce or a related financial claim can make orders affecting the funds, including precautionary attachment in appropriate cases. Whether and when a court will freeze a joint balance is case-specific and depends on the evidence and the applicable personal status framework; confirm the realistic options in your case with a licensed UAE lawyer before relying on any of them.

Practical sequence if a separation is coming: take dated statements of the joint account early; ask the bank what it requires to convert the mandate to joint signatures or to suspend single-signature withdrawals; and take advice before making any large withdrawal yourself — self-help that looks like stripping the account can rebound in the financial proceedings.

Non-residents and joint accounts

Non-residents can bank in the UAE, but on narrower terms — and every bank draws its own lines.

The UAE Government portal's banking guidance lists the documents banks most commonly require to open an account: Emirates ID, a valid UAE residence visa, passport or family book, a salary certificate or employment letter, and in some cases proof of address. That list tells you where non-residents stand — outside the standard onboarding path. Banks that accept non-resident customers do so under their own policies within the Central Bank's licensing framework, and in practice the offer is typically a savings-type account with restricted facilities rather than a full current account with a cheque book.

What to expect as a non-resident, and what to verify rather than assume:

• Account type and facilities. Which products a non-resident may hold — and whether a cheque book, overdraft or lending attaches — is set by each bank's own policy and can change; confirm the current position with the bank concerned before planning around it.
• Minimum balances and charges. Non-resident accounts commonly carry higher minimum-balance requirements than resident accounts. The exact thresholds and fees are set by each bank and can change; confirm the current figures with the bank concerned or a licensed UAE lawyer.
• Mixed-residency joint accounts. Whether a resident may hold a joint account with a non-resident co-holder — a resident worker and an overseas spouse, for instance — is again bank policy. Some banks allow it on specific products; others require all holders to hold residence visas. Ask the specific bank in writing.
• Documentation. Expect enhanced due diligence: source-of-funds evidence, bank references and tax-residency declarations are standard for non-resident onboarding.

If a longer-term move is in view, residence status changes the whole picture — see our guide to Golden Visa eligibility in the UAE for one of the routes that unlocks full resident banking.

Before you sign: practical protections

Ten minutes of configuration at opening prevents most joint-account disputes.

• Choose the mandate deliberately. Either-to-sign is for full mutual trust; both-to-sign is for everything else, including most business arrangements.
• If contributions are unequal, record the split with the bank at opening. The statutory presumption of equal shares yields only to an agreement recorded with the bank.
• Keep your own copies of the account agreement and every mandate change. Under the Central Bank's Consumer Protection Regulation, licensed banks must disclose the terms governing your account clearly — use that, and ask for the joint-account annex specifically.
• Agree in writing, between holders, what the account is for and what happens on exit. The bank does not need this document; the two of you will.
• Revisit the account on every life change — marriage, divorce filing, a co-holder's illness, a business dispute. The ten-day death-notification duty in Article (379)(4) is only the sharpest example of a general truth: joint accounts do not manage themselves.

Where to get help

If a joint account is already contested — a blocked share after a death, a drained balance in a divorce, a seizure against a co-holder — the fastest way forward is specific advice on your bank's terms and your evidence.
