How long does a typical multifamily office transition take from decision to full operation?
Plan on roughly six to ten months from the decision to full operation. A straightforward transition may finish sooner. Complex ownership structures, private investments, data cleanup, hiring, and governance work can extend the schedule. Start with reporting and custody, then add controls, workflows, and service improvements as the office settles.
A practical planning range
For a multifamily office transition, we usually plan in months, not weeks. SEI reports that a typical advisory business transition takes six to eight months from the decision until accounts and assets are working at the new custodian and the business is operating day to day. That provides a useful reference for a family moving onto an established multifamily office platform. SEI
A more involved build can take longer. Union Park Consulting documented a family office implementation that took ten months to establish the full operating environment. Custody and technology were in place within four months, while controls, procedures, reporting, and other operating functions continued afterward. Union Park Consulting
What happens during the transition
The first stage is definition. We agree on the services, decision rights, reporting needs, account ownership, and responsibilities that stay with the family or outside advisers.
Next comes the operating foundation. This can include account opening, custodian coordination, data collection, reporting setup, document management, payment controls, cybersecurity, and staff or provider onboarding. These workstreams often run in parallel, but delays in one area can hold up the launch.
The final stage is stabilization. The office tests reports, approvals, cash movements, capital call handling, tax information flows, and communications. The team then fixes exceptions and confirms who owns each recurring task. Full operation means the office can perform these duties consistently, with clear accountability. A system being technically live does not by itself complete the transition.
Anytime a system gets more complex, you have to find a way to simplify it.
How to keep the schedule realistic
Set a target launch date and work backward. Prioritize custody, reporting, cash controls, and the first recurring calendar of family obligations. Prepare ownership records and historical data early. Assign one person to make decisions and track dependencies. Keep the family’s existing advisers involved until the new process has produced reliable reports and completed at least one full operating cycle.
A six to ten month plan is a sensible starting point for many transitions. Use the shorter end when the office is joining an established platform and records are clean. Use the longer end when the work includes new governance, multiple entities, private assets, or new hires.
