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
A joint account in Nigeria is held in two or more names and run on a mandate that says who can sign: commonly either party alone, or all parties together. Banks set their own eligibility; Access Bank's diaspora FAQ, for example, allows joint diaspora accounts only for married couples. The main risks are that one holder can empty an either-to-sign account, some channels such as GTBank's 737 do not work on joint accounts, and the sources we checked found no Nigerian rule that hands the balance to the survivor when a holder dies.
Why diaspora families use joint accounts
The usual reason is practical. You send money home for a parent's care, school fees or a building project, and you want someone in Nigeria who can withdraw cash, visit the branch and deal with problems while you stay in control. A joint account seems to offer both. Before you open one, understand the mandate, the bank's own rules and what happens when things go wrong.
Mandates: who can sign
Every joint account carries a signing instruction, called the mandate, recorded on the account opening form and signature card. The common versions are:
| Mandate | What it means | Suits |
|---|---|---|
| Either to sign | Any one holder can withdraw, transfer or close alone | Spouses who trust each other fully |
| Both or all to sign | Every holder must approve each withdrawal | Building funds, family savings, larger sums |
| A plus any one | A named holder must sign, with one other | Parent and two children managing an estate fund |
Ask the bank which mandates it offers and how each works on the app, USSD and at the counter, because the electronic channels may not support every mandate. A both-to-sign account often cannot be run by mobile app at all.
What banks' own pages say
- Access Bank (Diaspora Banking FAQ): joint diaspora accounts are limited to married customers and need a copy of the marriage certificate; business partners cannot open one.
- Fidelity Bank (Diaspora Banking page): diaspora domiciliary accounts can have a nominee resident in Nigeria as a joint signatory.
- GTBank (737 FAQ): 737 USSD transfers are not available on joint accounts.
- FirstBank (FAQs): joint, corporate and multi-signatory accounts are not eligible for *894# USSD banking.
So a joint account may lose the quick channels a family member at home relies on. Check before you choose it.
The risks to weigh
One holder can act alone
On an either-to-sign account, the person in Nigeria can withdraw everything without asking you. The bank will follow the mandate, not the family understanding behind it.
Death of a holder
Many people assume the survivor simply keeps the money. Daily Trust's December 2023 explainer quotes a tier-one banker saying no Nigerian framework recognises "payable on death" arrangements, and that estates need probate or letters of administration before funds are released; it does not settle joint accounts. Our research found no CBN rule or statute fixing survivorship on joint accounts, so ask the bank in writing how it treats a joint account when one holder dies, and keep the answer. See writing a will for Nigerian assets.
Disputes and frozen accounts
If holders fall out, a bank faced with conflicting instructions may restrict the account until they agree or a court decides. On a both-to-sign account, one unreachable holder can freeze day-to-day use.
Tax and reporting abroad
Some countries require you to report foreign accounts you hold or can sign on. US persons, for example, count signature authority for the FBAR; see US and Nigeria tax.
Alerts and visibility
Distance makes oversight harder. Make sure transaction alerts on the joint account reach you by email or app, not only by SMS to a Nigerian line you rarely see. Agree in writing, even by a simple message, what the account is for, who may withdraw for what, and how often you will both review statements. That will not bind the bank, but it reduces family arguments later and gives you a record if a dispute ever reaches a lawyer.
Alternatives to a joint account
- Your own account plus transfers: keep the account in your name and send set amounts to the family member's own account.
- A separate account in their name that you fund, with no access to your main balance.
- A power of attorney for specific dealings, such as property, which is narrower and can be revoked. See power of attorney from abroad.
- A both-to-sign project account for building funds, so no single person can draw it down.
What to check first
- Which mandates the bank offers for diaspora joint accounts, and whether yours qualifies.
- Which channels (app, USSD, cards) work on that mandate.
- How the bank treats the account if one holder dies, in writing.
- Who receives alerts; make sure you do, wherever you are.
- Whether your country of residence requires you to report the account.
Where Pryme fits
Many diaspora families find a simpler pattern works: keep the money in your own account and send it as needed. A Pryme Personal Account can be opened from any country, and Eva, the Personal Assistant, can prepare regular transfers to family and remind you of bills, with nothing moving until you approve. For shared money, our guide to joint or separate accounts sets out the trade-offs.
Questions people ask
Can I open a joint account in Nigeria while living abroad?
Some banks allow it, on their own terms. Access Bank's diaspora FAQ limits joint diaspora accounts to married couples with a marriage certificate. Ask each bank.
What happens to a joint account in Nigeria if one person dies?
The sources we checked found no Nigerian rule fixing survivorship. Ask the bank in writing how it handles this, and make a will.
Can my mother withdraw from our joint account without me?
On an either-to-sign mandate, yes. On a both-to-sign mandate, she needs your approval for each withdrawal.
Does USSD work on joint accounts?
Often not. GTBank's 737 and FirstBank's *894# both exclude joint accounts, according to the banks' FAQs.
