Can Banks Deduct Money Workout Permission?

In Nigeria, one of the most common complaints among bank customers is unexplained debits money leaving accounts without clear consent. The simple answer is this: banks are not legally allowed to deduct money from your account without your authorization but there are important exceptions and conditions that every customer needs to understand.

Banking relationships are built on a contract between you and your bank. That contract defines when and how money can be removed from your account. Outside of those agreed terms, any deduction can be considered unauthorized and potentially illegal.

At the core of Nigerian banking law is the principle that a bank can only debit your account based on your mandate that is, your instruction, approval, or prior agreement. Legal experts emphasize that withdrawals must be carried out strictly according to the customer’s authorization, and any unauthorized debit may amount to negligence or breach of contract by the bank . This means that if a bank removes money without a valid reason tied to your agreement, you have the right to challenge it.

However, not every debit you didn’t “actively approve” is illegal. Many deductions happen because you already gave permission sometimes without realizing it. For instance, when you open a bank account, you agree to certain charges such as maintenance fees, ATM charges, SMS alerts, and transfer fees. These are regulated by the Central Bank of Nigeria (CBN) and are typically outlined in the bank’s terms and conditions. Once you accept those terms, the bank is allowed to deduct those charges periodically.

Another major situation where banks can debit your account is through direct debit mandates. This is common with loans, subscriptions, and utility payments. Once you sign a mandate, you authorize the bank (or a third party) to withdraw money automatically. Globally, direct debit systems require prior approval from the account holder before any deductions can be made . In Nigeria, this applies to loan repayments, salary advances, and even some fintech services.

Banks can also deduct money without fresh permission in cases involving loan recovery. If you owe a bank money whether through a loan, overdraft, or credit facility the bank may legally debit your account to recover the debt, especially if you signed an agreement allowing them to do so. In some cases, this can even extend to other accounts linked to your identity within the same bank.

There are also regulatory or legal deductions. For example, a court order, government directive, or tax obligation can authorize a bank to debit your account. In such cases, the bank is acting on legal instruction, not personal permission.

That said, unauthorized debits do happen and they are a serious issue in Nigeria’s banking system. These can come in the form of unexplained charges, duplicate debits, failed transaction reversals, or even fraud. Studies and reports have shown that customers sometimes experience deductions labeled as ATM or POS charges, even when no transaction was made . In more severe cases, funds may be withdrawn due to security breaches, compromised PINs, or insider fraud.

The law is clear on what should happen next. If a bank debits your account without proper authorization, it must provide a valid explanation or reverse the transaction. Under Nigeria’s Cybercrime Act, financial institutions are required to justify any debit or refund the money within a specified period when challenged. Failure to do so can attract penalties and legal consequences .

As a customer, you also have responsibilities. Banks often argue that many unauthorized transactions happen because customers unknowingly expose their details sharing PINs, clicking phishing links, or allowing others access to their cards. While this doesn’t excuse wrongful debits, it can affect how disputes are resolved.

If you notice any suspicious deduction, the best course of action is to act immediately. Report the issue to your bank, request a detailed explanation, and escalate to the CBN if necessary. Nigerian law provides multiple remedies, including refunds, compensation, and even court action in cases of negligence or fraud .

In summary, Every legitimate debit must be backed by your prior consent, a contractual agreement, or a legal directive. If none of these apply, then the deduction is not only wrong it may be unlawful, and you have every right to demand a reversal and accountability.
