Foreign-based directors of Singapore private companies face a recurring problem: they cannot always attend board meetings, and Singapore law does not universally permit voting by proxy in the boardroom. The Companies Act’s answer is the alternate director — a substitute director appointed by an existing director to act in their absence. Used properly, alternates keep a board functional across time zones; used badly, they create governance gaps, personal liability risks, and share-transfer complications.
Here is what every Singapore founder, foreign director, and corporate secretary needs to understand about alternate directors in 2026.
Legal basis: what does the Companies Act say?
The Companies Act 1967 does not create an automatic right to appoint an alternate. Instead, the power comes from the company constitution. If the constitution is silent, no alternate can be appointed. Most Singapore constitutions based on the Model Constitution or long-established templates do include an alternate director clause, but this is worth checking.
Where the constitution permits, an existing director may appoint another individual (usually with board approval) to act in their place at board meetings. The alternate signs board resolutions, attends meetings, and votes as if they were the appointing director.
What an alternate director IS and IS NOT
An alternate director IS a full director of the company for the periods and matters they are appointed to act on. Their name is filed with ACRA under section 173 as a director; they are personally subject to directors’ duties under sections 156 to 157A; and they can bind the company by signing on its behalf when acting as alternate.
An alternate director is NOT: (a) a proxy — proxies attend general meetings of shareholders, not board meetings; (b) an agent of the appointing director — they act as a director in their own right; (c) a rubber stamp — they owe fiduciary duties to the company, not to the appointing director; and (d) automatically empowered — their appointment must comply with the constitution.
Common uses of alternate directors
- Foreign directors who cannot easily fly in for every board meeting appoint a Singapore-based alternate (often a trusted advisor or corporate services officer).
- Investor-nominated directors — an investor entitled to nominate a director may want a bench of two, one primary and one alternate, so meetings quorum is never lost.
- Long absences — a director on extended personal leave, maternity, or an overseas posting appoints an alternate for the duration.
- Illness contingency — some boards preserve continuity by pre-appointing alternates for every director as a governance best practice.
How to appoint an alternate director
Step 1: Check the constitution
Confirm the constitution permits alternate director appointments and identify any restrictions (e.g. requirement that the alternate be pre-approved by other directors, or ineligibility of certain persons).
Step 2: Board approval (if required)
Most constitutions require the board’s consent to the specific alternate proposed. Circulate a directors’ written resolution or convene a board meeting to record the approval.
Step 3: Notice of appointment
The appointing director signs a written appointment (usually a short notice or deed of appointment) specifying the alternate’s name, effective date, scope (permanent or for specific meetings), and expiry conditions. The alternate signs a consent to act, disclosing any conflicts of interest and confirming they meet the disqualification criteria of section 149 (not undischarged bankrupt, not convicted of relevant offences).
Step 4: Lodge with ACRA within 14 days
File the appointment on BizFile+ under section 173 to update the register within 14 days. Note that the alternate is treated as a director, so ACRA fees apply. See our guide on adding and removing directors.
Step 5: Update the statutory register
Enter the appointment in the Register of Directors and, if the alternate is also a nominee, in the Register of Nominee Directors. Update the CorpPass Administrator list where relevant.
Duties and liabilities of an alternate director
An alternate is subject to the same directors’ duties as any Singapore director:
- Section 157 — duty to act honestly and use reasonable diligence in discharging the duties.
- Section 156 — duty to disclose interests in transactions with the company.
- Section 157A — general duty of skill, care and diligence (post-2018 update).
- Common law fiduciary duties — no conflicts, no secret profits, no misappropriation.
Crucially, the alternate is liable for decisions they participate in — they cannot claim they were “just following instructions” from the appointing director. Where the alternate votes on a related-party transaction of the appointing director, the alternate’s own duty of disclosure and abstention applies.
Vacation and termination of an alternate
An alternate director vacates office automatically when the appointing director ceases to hold office (resignation, removal, death, disqualification). The appointing director can also revoke the alternate’s appointment at any time by written notice. The revocation must be filed with ACRA within 14 days. If the alternate personally becomes disqualified under section 149, they cease to hold office immediately.
The Singapore-resident director requirement
Under section 145, every Singapore private company must have at least one director who is ordinarily resident in Singapore. An alternate director generally does NOT count towards this requirement — the resident director must be a substantive appointment, not an alternate for a foreign director. Get this wrong and your company can be struck off or face compliance action.
If your only Singapore-resident director resigns and you rely on an alternate, ACRA can require you to appoint a new resident director within a specified period. See our guide on nominee directors in Singapore for how to fill this gap.
When NOT to use an alternate director
Do not use an alternate as a workaround for: (a) the Singapore-resident director requirement; (b) skirting director disqualification (an appointment to a disqualified person’s alternate is void); (c) hiding beneficial ownership (the alternate is publicly disclosed on ACRA); or (d) covering long-term incapacity of the primary director — in that case, resign and appoint the alternate as a full director.
Practical governance tips
Board best practice for alternate directors in 2026: keep the appointment specific and time-boxed rather than open-ended; brief the alternate on live board matters before each meeting they attend; ensure D&O insurance policy covers alternates (many policies do not by default); document what falls outside the alternate’s scope (e.g. share transfers, major contracts); and review the appointment at every AGM to confirm it is still needed.
Alternate directors are a flexible governance tool that suits the reality of Singapore boards with international directors. Used with care, they preserve board continuity across time zones. Used casually, they create disclosure gaps, personal liability surprises, and share-transfer headaches at the worst possible moment. Talk to your corporate secretary before you appoint one — five minutes of drafting will save five hours of retro-fitting later.
