How to choose
- Get 3 partner-led pitches before deciding. The firm matters less than the specific partner who will run your matter day-to-day.
- Test cross-border depth if your family is multi-country. Ask the partner walking you through their last 3 multi-jurisdiction matters.
- Check substance bandwidth. For 13U, the partner should be able to talk concretely about ongoing substance compliance, not just initial application drafting.
- Tax + legal should already work together. The two firms you pick should have a track record of joint matters with each other.
- Trust company is a separate decision. Don't bundle blindly with your private bank if it doesn't match the family structure you want.

Top Singapore family office advisors — FAQs
Who are the top family-office tax and legal advisors in Singapore?
For legal counsel: Drew & Napier, Allen & Gledhill, WongPartnership, and Rajah & Tann have established SG private-client practices. For tax advisory: KPMG, PwC, EY, and Deloitte run dedicated SG family-office practices. For trust services: BoS Trustees, UBS Trustees Singapore, EFG Trust, and several specialist trust companies. Choice depends on family complexity, jurisdictional reach, and budget.
How much do these advisors cost?
Legal counsel for a credible 13O / 13U family-office setup runs S$50,000–200,000 for the one-off scope. Tax advisory adds S$30,000–80,000. Big-name firms (Drew & Napier, Allen & Gledhill) anchor at the higher end. Boutique private-client specialists can be 40–60% more efficient on simpler structures.
Do I need both a SG law firm and a tax advisor?
Almost always yes. Law firms handle the structural documentation (VCC incorporation, employment contracts, family-governance docs, MAS application drafting). Tax advisors handle the 13O/13U scheme analysis, IRAS interactions, ongoing tax-residency planning, and cross-border tax-treaty work. The two roles overlap but are distinct.
How do I pick between Drew & Napier vs Allen & Gledhill vs WongPartnership?
All three handle credible family-office work. Drew & Napier has the longest-standing private-client practice and deep MAS relationships. Allen & Gledhill has strong cross-border + trust capabilities. WongPartnership has tightly integrated tax + estate-planning team. Decision often comes down to which partner you connect with at the diligence stage rather than firm-level capability differences.
Are these firms paying for placement on this list?
No. This is editorial content based on public profile, MAS-published practice rankings (where available), Asia Legal 500 / Chambers Asia tier rankings, and our own observation of the SG family-office market. We do not accept payment for inclusion in editorial rankings.
