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.
