Every Singapore company knows, or is quickly told, that a change of director has to be filed with the Accounting and Corporate Regulatory Authority (ACRA) within fourteen days. Far fewer companies realise that filing the change with ACRA does not, by itself, change anything at the bank. The company’s statutory register updates. Bizfile updates. The bank’s own list of people who can move money out of the account does not, until someone separately tells the bank and the bank runs its own checks.
This gap catches out newly incorporated companies bringing on a second director, growing companies reshuffling their board, and family businesses handling a director’s retirement or death. In each case the account itself keeps operating exactly as before, under the old mandate, until the bank is formally asked to update it. That can mean a departed director who technically still has signing rights, or a newly appointed director who cannot yet approve a single payment.
This guide sets out what a bank mandate actually covers, why it does not move in step with ACRA, when it needs to be updated, and the practical steps and documents involved. It is written generically: banks differ in their internal forms and turnaround times, and this article does not recommend or compare any specific institution.
What a Bank Mandate Actually Is
A bank mandate is the bank’s own internal record of who is authorised to operate a company’s account and on what terms: who can view balances, who can approve or execute payments, whether one signature is enough or two are required, and any transaction limits attached to each signatory. It is set up when the account is opened, based on a board resolution and supporting documents the company provides at that time, and it sits entirely within the bank’s own systems.
The mandate is separate from, though related to, the company’s statutory register of directors and its Bizfile profile with ACRA. A person can be validly appointed as a director in law, correctly reflected on Bizfile, and still have no authority to operate the bank account until the bank has separately added them to the mandate. The reverse is also true: someone who has resigned as a director remains on the bank’s mandate, with live signing rights, until the company tells the bank to remove them.
Why the Bank’s Records Do Not Update Automatically
Banks in Singapore are not connected to Bizfile in a way that automatically pushes director or shareholder changes into their own account records. Under the anti-money laundering and countering the financing of terrorism framework that applies to banks, customer due diligence is something the bank itself must actively perform and keep current, not something it can infer from a public register. The Monetary Authority of Singapore’s Notice 626 sets out the ongoing due diligence obligations banks owe their corporate customers, including keeping customer information accurate and current and treating an unexplained change in signatories or controllers as something worth a closer look.
In practice this means a change of director, a change of shareholder, or even a change to who within the same leadership team is authorised to sign, triggers a fresh round of verification at the bank: identity documents for the new signatory, a board resolution authorising the change, and sometimes updated beneficial ownership information for the company as a whole. The bank is not being difficult; it is meeting its own regulatory obligations independently of what ACRA already has on file.
When You Need to Update the Mandate
Appointment of a New Director Who Will Also Sign
If the new director is meant to operate the account, whether alone or jointly with others, the mandate needs updating before they can transact. Being validly appointed under the Companies Act 1967 is not the same as being able to move company funds.
Resignation, Removal or Disqualification of a Signatory
This is the change most often missed, because the urgency runs the wrong way. Nobody chases the bank to remove a departed director’s signing rights the way they chase to add a new one. Left unaddressed, it is a real control weakness: someone with no further stake in the company retains the ability to authorise payments. ACRA’s own guidance on notifying a director’s resignation is a useful starting point, since the ACRA filing should be actioned before the bank is approached.
Death of a Director or Sole Signatory
Banks typically freeze or restrict an account, or at minimum flag it for review, once notified that a signatory has died. The company will need to work through succession of authority, often involving the remaining directors and, depending on the company’s constitution, a fresh board resolution, before normal operation resumes.
Change in Shareholding or Ultimate Beneficial Ownership
Even where the directors and existing signatories stay the same, a material change in who owns or controls the company (a new investor taking a significant stake, for example) can trigger the bank’s own periodic or event-driven customer due diligence refresh, including fresh beneficial ownership declarations.
Change to the Signing Arrangement Itself
Sometimes nobody has left or joined the board, but the company wants to change how the account is operated: moving from single-signatory to dual-signatory approval, adding transaction limits, or removing an operational staff member’s standing authority. These are mandate-only changes and still require the bank’s formal update process.
The Practical Process, Step by Step
- File the underlying change with ACRA first. A director appointment or cessation must be filed within fourteen days under section 173 of the Companies Act 1967. Most banks will not act on a mandate change until the company’s Bizfile profile already reflects it, so this step comes before, not alongside, the bank request.
- Pass a board resolution. The resolution should name the outgoing and incoming signatories, describe the new signing arrangement (sole, joint, or joint-with-limits), and authorise a named officer to submit the change to the bank.
- Obtain an updated Bizfile business profile. Most banks want a profile dated after the ACRA filing was accepted, not the one used to open the account originally.
- Complete the bank’s own mandate change form. Every bank has its own version; some accept it online through corporate internet banking, others require the form to be submitted in branch or through a relationship manager.
- Provide identification and verification for any new signatory. This usually means a passport or NRIC, proof of residential address, and in many cases an in-person or video verification appointment, particularly for a signatory the bank has not previously dealt with.
- Confirm the change has taken effect before relying on it. Ask the bank to confirm in writing (email is generally acceptable) once the mandate has actually been updated, rather than assuming the change is live once the form is submitted.
Documents Banks Typically Require
| Document | Purpose | Typically Needed For |
|---|---|---|
| Certified board resolution | Authorises the specific mandate change and names the affected signatories | All mandate changes |
| Updated Bizfile business profile | Confirms the underlying director or officer change is already registered with ACRA | Director appointment, resignation or removal |
| Identification document (passport or NRIC) | Verifies the identity of a new signatory | New signatory only |
| Proof of residential address | Supports the bank’s own customer due diligence file | New signatory only |
| Updated register of directors or officers | Cross-checks the company’s internal statutory record against the bank’s | Director appointment, resignation or removal |
| Beneficial ownership declaration | Confirms who ultimately owns or controls the company where shareholding has changed | Change in shareholding or ultimate beneficial owner |
| Death certificate and grant of probate or letters of administration (where relevant) | Establishes authority to act following the death of a director or sole signatory | Death of a signatory |
Common Pitfalls and Delays
The most common cause of delay is sequencing: attempting to update the bank mandate before the ACRA filing has actually been processed, so the Bizfile profile the bank receives still shows the old director. Filing the ACRA change and then waiting for confirmation before approaching the bank avoids a round trip.
A second common issue is treating the mandate update as informal, for example telling a relationship manager verbally that a director has left, without submitting the bank’s own form or board resolution. Verbal notice is rarely sufficient to actually remove someone’s signing rights.
A third issue, particularly for companies with a sole director who is also the sole shareholder, is not planning for incapacity or death at all. Where there is only one signatory and no succession arrangement recorded, the company can find its account effectively frozen at the worst possible moment. Building continuity into the constitution and the bank mandate from the outset, well before it is needed, is worth doing during the first 30 days after incorporation rather than after a crisis.
How a Registered Office and Company Secretary Help
Because the ACRA filing has to precede the bank filing, and because banks want documents that are internally consistent (the board resolution, the Bizfile profile and the register of directors all telling the same story), this is an area where a company secretary earns their fee. A secretary who is already handling the statutory filing of the director change can prepare the board resolution in the same sitting, produce the updated Bizfile extract as soon as ACRA processes it, and keep the company’s own register of directors synchronised throughout, so nothing is missing when the bank asks for it.
This matters more than it sounds, because banks that receive an incomplete or inconsistent set of documents will simply pause the request and ask for more, which is where most of the real-world delay comes from. It is rarely the bank being slow; it is usually a document gap that a properly sequenced process would have avoided. Getting this right in the company’s first year of compliance, when the board is often still settling, sets the pattern for every later change. Appointing a company secretary who understands both sides of this process, not just the statutory filing side, is one of the more practical reasons smaller companies choose to outsource the role rather than handle it internally.
A Worked Example
A Singapore private limited company with two directors, A and B, brings on a third director, C, who will also become a joint signatory alongside A. The company secretary files C’s appointment with ACRA, which is processed within a few days. Once the updated Bizfile profile is available, the secretary prepares a board resolution naming C as an additional authorised signatory under the existing joint-signing arrangement, and submits this to the bank together with C’s identification, proof of address and the updated Bizfile extract. The bank completes its own verification of C, including a short video call, and confirms in writing that the mandate has been updated. Only at that point can C actually approve payments; being named a director on ACRA’s records was a necessary first step, but not, on its own, sufficient.
Final Thoughts
A bank mandate is one of the few places where a Singapore company’s statutory position and its practical, day-to-day operating position can quietly diverge. Treating a mandate update as an automatic consequence of an ACRA filing, rather than a separate step that has to be actively requested and documented, is the most common reason companies find themselves with an account that will not do what their own register says it should. Building the mandate update into the same workflow as the director change itself, with the paperwork prepared consistently from the start, keeps the account matching the company’s actual governance at every stage.
