The fractional office guide

Use this guide to turn “we need more coordination” into a practical description of the work. The goal is an arrangement you can understand and evaluate, whatever label a provider uses.

Define fractional in the proposal

Ask the provider to spell out what “fractional” means in its engagement. Which professionals are available, how much time is included, and who manages outside specialists? Treat the term as a prompt for questions rather than a guarantee of a particular service package. Put expectations in writing before beginning.

Keep the relationships that work

Make a list of the professionals you already use and the responsibilities each handles. Ask a prospective coordinating advisor how they would work with that team. There may be no reason to replace a trusted CPA or attorney if the real problem is an unclear handoff or a missing planning calendar.

Turn gaps into assignments

For each unresolved issue, record an owner, the next action, and a date for review. Examples might include confirming who supplies a tax estimate, collecting a trust document, or updating the family’s cash needs. Our checklist is a conversation aid. Its count of checked items is not a financial score or a recommendation to hire a family office.

Separate advice from execution

Ask who can recommend, authorize, and carry out each action. Investment advice, legal work, tax preparation, and administrative tasks should not be treated as interchangeable. Investor.gov and FINRA offer guidance on evaluating investment professionals and their roles.14 Request a clear description of services that need a separate engagement.

Agree on cost and a review rhythm

Request a complete fee proposal, including the costs of external professionals and work outside the base scope. Fees can be structured in different ways.2 Agree on how you will review open items and whether the arrangement is delivering the coordination you wanted. Check the investment professional’s background before hiring.3
