AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Who can withdraw from a joint account in Nigeria is set by the mandate the holders signed when it was opened: "either to sign" lets any one holder act alone, while "both to sign" or "all to sign" needs every signature. What happens on a holder's death is not set out in a CBN rule we could find; it depends on the account terms, so ask your bank in writing before it matters.
The mandate is the rulebook
When you open a joint account, the bank asks you to sign a mandate: an instruction that tells it who may operate the account and how. That document, plus the bank's account terms, decides almost every question about the account later. Couples, siblings, business partners and parents with adult children all use joint accounts, and the mandate is where most disputes start or are avoided.
| Mandate type (common wording) | Who can withdraw | Suits |
|---|---|---|
| Either to sign / any one to sign | Any one holder, alone | Couples or family who trust each other and want convenience |
| Both to sign / all to sign | Only with every holder's signature or approval | Savings for a shared goal; business partners |
| Any two to sign (of three or more) | Any two holders together | Associations, family groups |
| Named signatory for limits | One holder up to a limit, two above it | Small businesses and groups |
Wording differs between banks, and not every bank offers every option on every account type. Ask for the mandate form, read it before signing, and keep a copy.
Digital channels can work differently
Joint mandates do not always fit apps and USSD. FirstBank's FAQ, for example, says its *894# USSD service is for individual accounts, and joint, corporate and multi-signatory accounts are not eligible. If you need both signatures, expect to use internet banking with an approval set-up, or the branch. Ask your bank how its app handles your mandate.
Changing or ending a joint account
- Changing the mandate usually needs the agreement of all holders, in writing.
- If you fall out with the other holder, tell the bank in writing that you dispute further withdrawals. Ask what the bank will do; it may suggest changing the mandate to both-to-sign or restricting the account until you agree.
- Closing the account and splitting the balance also normally needs everyone's instruction.
- If there is a court case between the holders, the bank will follow a court order.
Example: a sibling account after a disagreement
Example only. Three siblings open an account on an "any one to sign" mandate to pool ₦150,000 a month each for their mother's care. After a year the balance is ₦5,400,000 (₦450,000 × 12). One sibling withdraws ₦2,000,000 without telling the others. Because the mandate allowed any one to sign, the bank acted on a valid instruction, and the dispute is between the siblings, not with the bank. Had the mandate been "any two to sign", the bank would have needed a second signature. The lesson is to pick the mandate for the worst day, not the best.
What happens when one holder dies
This is the question people most often get wrong. Two different outcomes are possible in principle: the surviving holder takes the whole balance, or the deceased holder's share passes into their estate. We could not find a CBN rule or statute that settles which applies to Nigerian joint accounts generally, so the answer depends on the account terms and, in a dispute, on a court.
What is clear is how banks react to news of a death. TEMPLARS' November 2025 paper on account restrictions notes that a bank that receives notice of a customer's death stops withdrawals, and after that only the legal representatives of the estate deal with the deceased's account. In practice, expect a joint account to be reviewed, and possibly restricted, when the bank learns that a holder has died.
What to do now, while everyone is alive
- Ask the bank in writing: "If one of us dies, what happens to the balance and who can operate the account?" Keep the reply.
- If you want the survivor to take the balance, ask whether the mandate or terms can say so.
- If you want each person's share to go to their own heirs, consider separate accounts or a will that addresses the money.
- Do not rely on next-of-kin details for this; read next of kin versus beneficiary.
If a holder has already died, see claiming a dead relative's bank account and steps when there is no will.
Deposit insurance on joint accounts
The NDIC's FAQ says a joint account with a valid mandate and withdrawal rights is insured separately from each owner's individual accounts at the same bank. Example only: if you hold ₦3,000,000 alone and ₦4,000,000 jointly with your spouse at one commercial bank, the two are treated as separate for cover purposes, each up to the applicable limit. Check the current limits on the NDIC site; our guide to NDIC limits explains them.
For whether a joint account suits you at all, read joint or separate accounts for couples.
Questions people ask
Can one person withdraw from a joint account in Nigeria?
Only if the mandate allows it, for example "either to sign". If the mandate is "both to sign", every holder must approve.
What happens to a joint account when one person dies in Nigeria?
The bank will usually review or restrict the account once told of the death. Whether the survivor takes the whole balance depends on the account terms; ask your bank in writing in advance.
Can I remove my name from a joint account?
Changing the mandate or closing the account usually needs all holders' written agreement. If you disagree, tell the bank in writing and ask how it handles disputes.
Is a joint account insured by NDIC?
Yes. The NDIC says a joint account with a valid mandate and withdrawal rights is insured separately from each owner's individual accounts, up to the applicable limit.
