Malaysian Banking Law – Establishing Customer Status in Banking Relationships


Case Scenario
Ms. Sara frequently visited a commercial bank to cash crossed cheques issued by her business clients. Over a number of years, the bank officers willingly assisted her even though she never opened a current or savings account with the bank. The bank also did not impose any charges for these transactions.
Because of the repeated dealings, Ms. Sara believed that she had become a recognised customer of the bank. Subsequently, one of the cheques presented by her turned out to be forged, causing substantial financial losses. Ms. Sara argued that the bank owed her legal duties normally owed to customers, including the duty of care and proper verification during banking transactions.
The bank denied liability and contended that:
  • Ms. Sara never maintained any account with the bank;
  • the transactions were merely occasional banking services;
  • no formal banker-customer relationship existed; and
  • repeated transactions alone were insufficient to establish customer status.
Applying the principles established in Great Western Railway Co v London and County Banking Co Ltd, Robinson v Midland Bank Ltd, and Commissioners of Taxation v English, Scottish and Australian Bank Ltd, the court would likely hold that Ms. Sara was not a customer because she did not maintain any form of account or recognised banking relationship with the bank.
This scenario demonstrates the importance of identifying the exact point at which the banker-customer relationship arises because significant legal duties only exist once customer status is established.


Meaning of “Customer” in Banking Law
The term “customer” is fundamental in banking law because the relationship between a bank and its customer forms the basis of many banking rights and obligations. Generally, a customer refers to a person who maintains an account with a bank or engages the bank to provide banking services.
However, neither Malaysian nor UK banking legislation provides a complete statutory definition of the term. Consequently, the legal meaning of “customer” has been shaped primarily through judicial decisions.
Once a banker-customer relationship exists, the bank becomes subject to important legal duties, including:
  • the duty of confidentiality;
  • the duty to honour valid payment instructions;
  • the duty to exercise reasonable care and skill; and
  • compliance with banking and financial regulations.
Because of these significant obligations, courts carefully determine whether a true banker-customer relationship has been formed.


Position Under Malaysian Law
Under Malaysian law, no comprehensive statutory definition of “customer” exists.
The Financial Services Act 2013 does not expressly define the term “customer.” Nevertheless, it defines a “depositor” as a person entitled to repayment of a deposit, whether the deposit was made personally or by another person.
This means that the person legally entitled to the deposited funds is recognised as the depositor even if another individual physically deposited the money into the account.
For example:
  • where parents deposit money into their child’s account, the child becomes the depositor because the child is entitled to repayment; and
  • where an employer credits salary into an employee’s account, the employee becomes the depositor even though the employer made the payment.
Similarly, the Bills of Exchange Act 1949 regulates negotiable instruments such as bills and cheques but does not define the term “customer.”
As a result, Malaysian courts continue to rely heavily on English common law authorities when determining customer status.


Position Under UK Law
The position under UK law is similar because there is also no statutory definition of “customer.”
Neither the Bills of Exchange Act 1882 nor the Cheques Act 1957 defines the term.
Consequently, English courts developed judicial principles to determine:
  • who qualifies as a customer; and
  • when the banker-customer relationship begins.
The most influential cases include:
  • Great Western Railway Co v London and County Banking Co Ltd;
  • Robinson v Midland Bank Ltd; and
  • Commissioners of Taxation v English, Scottish and Australian Bank Ltd.


Great Western Railway Principle
A major authority on customer status is Great Western Railway Co v London and County Banking Co Ltd.
Facts
A man had, for several years, regularly exchanged crossed cheques for cash at a bank where he did not maintain an account. The bank did not charge any fee for the service.
Held
The House of Lords held that the man was not a customer. The court explained that the bank collected the cheques for itself and not on behalf of the individual.
Lord Davey stated:
“… there must be some sort of account, either a deposit or a current account or some similar relation, to make a man a customer of a banker.”
The court also emphasised that:
  • occasional banking services alone are insufficient; and
  • artificial arrangements such as using the term “sundry customer” cannot automatically create customer status.
This case established the important principle that some form of account or recognised banking relationship is necessary before a person becomes a customer.


Robinson v Midland Bank Ltd Principle
The reasoning in Great Western Railway Co v London and County Banking Co Ltd was later reinforced in Robinson v Midland Bank Ltd.
Facts
A person claiming to be a customer attempted to hold the bank liable for funds passing through an account even though the money did not belong to him.
Held
The Court of Appeal held that the bank was not liable. The court explained that although the term “customer” is difficult to define precisely, the chief criterion is the existence of an account through which banking transactions are conducted.
The court further held that:
  • dealings unrelated to banking business are insufficient; and
  • casual services alone do not establish customer status.
Robinson therefore strengthened the principle that the existence of an account forms the central basis of the banker-customer relationship.


Commissioners of Taxation Principle
An important development occurred in Commissioners of Taxation v English, Scottish and Australian Bank Ltd concerning the duration of the banking relationship.
Facts
One issue before the House of Lords was whether a man qualified as a customer when his only connection with the bank at the material time was payment of a single cheque into an account opened solely for collection purposes.
Held
The House of Lords held that the man was a customer because duration of the relationship was not essential.
Their Lordships explained:
“The word ‘customer’ signifies a relationship in which duration is not of the essence.”
The court further stated that once a bank accepts money into an account on the basis that it will honour cheques up to the amount standing to the customer’s credit, the person becomes a customer regardless of whether the relationship is of short or long duration.
The case distinguished between:
  • a person receiving casual banking assistance without an account; and
  • a person maintaining an account with the bank, even if recently opened.
Therefore, the first payment into an account was sufficient to establish customer status.


Relationship Between the Three Cases
The three cases collectively establish the modern legal position regarding customer status.
Great Western Railway Case
This case established that:
  • casual dealings alone are insufficient; and
  • some form of account or banking relationship is necessary.


Robinson v Midland Bank Ltd
This case reinforced that:
  • the existence of an account is the chief criterion; and
  • isolated banking services do not create customer status.


Commissioners of Taxation Case
This case clarified that:
  • duration of the relationship is irrelevant; and
  • customer status may arise immediately once an account is opened and money is deposited.
Together, these cases establish that the essential requirement is not the length of the relationship but the existence of an account relationship itself.


Critical Analysis
The combined effect of these judicial decisions demonstrates the courts’ attempt to balance:
  • protection of banks from unlimited liability toward non-customers; and
  • protection of genuine account holders regardless of how recently the relationship began.
The modern approach adopted in Commissioners of Taxation v English, Scottish and Australian Bank Ltd is commercially practical because modern banking relationships may arise instantly through:
  • internet banking;
  • digital account registration;
  • mobile banking applications; and
  • electronic fund transfers.
However, uncertainty still exists concerning:
  • fintech platforms;
  • digital wallets; and
  • cryptocurrency services
where users may not maintain traditional banking accounts.
As banking technology evolves, the traditional judicial principles established in these cases may require further legislative clarification and adaptation.


Practical Importance
The banker-customer relationship remains extremely important because banks owe substantial legal duties once customer status arises.
Examples include:
  • a person opening a savings account becomes a customer immediately upon the first deposit;
  • an employee receiving salary into an account becomes entitled to repayment as a depositor;
  • a business maintaining a current account clearly qualifies as a customer; while
  • a person merely cashing cheques occasionally without an account may not qualify as a customer.
Banks therefore insist on formal account-opening procedures to establish legal certainty.


Solutions to the Case Scenario
Several legal and practical measures may reduce disputes similar to Ms. Sara’s case.
1. Formal Account Requirements
Banks should require proper account-opening procedures before repeatedly providing banking services to individuals.
2. Clear Communication Policies
Financial institutions should clearly explain that occasional banking services do not automatically establish customer status.
3. Legislative Reform
Malaysia may consider introducing a statutory definition of “customer” to reduce legal uncertainty.
4. Consumer Awareness
Banks and regulators should educate the public regarding:
  • the meaning of customer status;
  • when banking duties arise; and
  • the importance of maintaining formal banking relationships.
5. Modern Digital Banking Guidelines
Regulators should develop clearer rules concerning digital banking users and fintech customers who may not maintain traditional bank accounts.
Had these measures been implemented, Ms. Sara would have understood that repeated cheque-cashing transactions alone were insufficient to establish a banker-customer relationship.


Conclusion
The banker-customer relationship forms the foundation of banking law because it determines the legal rights and obligations owed between banks and individuals.
Although Malaysian and UK statutes do not provide a complete statutory definition of “customer,” courts have developed important judicial principles to clarify the concept.
Cases such as Great Western Railway Co v London and County Banking Co Ltd, Robinson v Midland Bank Ltd, and Commissioners of Taxation v English, Scottish and Australian Bank Ltd establish that:
  • the existence of an account is essential; while
  • duration of the relationship is not.
These principles continue to influence modern banking law despite ongoing developments in fintech and digital financial services.
