What Happens If You Spend Money Sent to You by Mistake in Nigeria? (Legal Guide)

1. Introduction: The Unwanted Windfall – Money Sent by Mistake in Nigeria

We’ve all dreamed of unexpected money appearing in our accounts. But in Nigeria’s digital banking era where 1.4 billion transactions worth ₦105 trillion occurred in Q1 2026 (CBN data), mistaken transfers are increasingly common.

A “mistaken transfer” occurs when:

• Someone sends money to your account by error (wrong account number/name)
• A bank processes an incorrect amount
• A technical glitch duplicates a transaction

The temptation is real, but Nigerian law is clear: that money isn’t yours. This guide explains exactly what happens if you spend it and the right steps to take.

2. Is Spending Mistakenly Sent Money Legal in Nigeria? Understanding the Law

The Principle of Unjust Enrichment

Nigerian common law states you cannot legally benefit from another’s mistake. Even if the sender made the error, keeping the funds constitutes “unjust enrichment” – you’re gaining at someone else’s expense without legal justification.

Relevant Nigerian Statutes

1. Criminal Code Act:
   • Section 383: Theft – If you intentionally keep/spend money knowing it’s not yours
   • Section 390: Fraudulent Conversion – Converting someone else’s property (money) for your own use
2. CBN Guidelines on Electronic Payments:
   • Banks must establish processes for resolving mistaken transfers
   • Recipients must cooperate with reversal requests

Case Law: In First Bank v. Ozokwere, Nigeria’s Supreme Court ruled banks must refund customers for failed transactions, establishing precedent for money recovery in error cases.

3. The Immediate Aftermath: What Happens When Money Lands in Your Account by Mistake?

Here’s the typical sequence:

1. Notification: You receive an SMS/email alert from your bank (e.g., “Credit Alert: ₦500,000 from GTBank Acct XXXX”)
2. Sender Discovers Error:
   • They contact their bank (e.g., Zenith Bank) to report the mistake
   • The sending bank initiates a recall request to your bank (e.g., Access Bank)
3. Bank Investigation:
   • Your bank places a temporary hold on the funds
   • They contact you via phone/email to verify the transaction
4. Resolution:
   • If uncontested, funds are reversed within 3-5 working days (CBN timeline)
   • If contested, the matter escalates legally
