You Are the Self Managed Family Office: Running a Family's Entities Without a Staff

When people hear "family office," they picture a firm: a suite with a CIO, a controller, and someone whose whole job is keeping the paperwork straight.

Most family offices aren't that. A self managed family office is usually one person — maybe two — handling a family's LLCs, trusts, and investments without hired staff, serving as the central point for documents, records, deadlines, and the questions that come with all those entities. Nobody hired them. There was no onboarding. At some point the entities existed, the documents started arriving, and someone had to be the person who knew where things were. If you're reading this, that someone is probably you.

I'm that person for my own family's structure, so I mean this without any judgment: the job you've absorbed is a real job. It has a name — the back office — and in an institutional family office it's someone's entire role. What follows is about doing that role on purpose: collecting entity documents, keeping corporate records, tracking compliance deadlines, mapping how the family's entities fit together, and systemizing the work so it doesn't depend on one person's memory. Without that kind of structure, documents get lost, deadlines get missed, and the family's legal and financial affairs become harder to manage than they need to be.

The job nobody was hired for

Strip away the mystique and a family office back office does four things.

It collects the family's documents. The CPA has some, the attorney has others, the wealth manager sends statements, the fund administrators have portals. Every provider distributes their own way — email attachments, portal links, paper mail — and none of them coordinates with the others. Someone has to be the place where it all converges. By default, that place is your inbox, which is not a filing system; it's a queue that never empties.

It keeps each entity's records straight. The family LLCs, the trusts, the holding company — each is its own legal thing with its own document set: formation papers, operating agreements and amendments, trust instruments, EIN letters, tax returns, K-1s. Multiply a modest structure — say eight entities — by that checklist and you're the registrar of a few hundred documents whose current versions matter.

It watches every deadline. Annual reports, registered agent renewals, franchise taxes, each state on its own calendar. The institutional version of this job has a compliance calendar and someone paid to watch it. The self-managed version usually has memory, a spreadsheet, and whatever notices happen to reach the right mailbox.

It answers the family's questions. Who's trustee on the kids' trust? Which entity holds the lake house? What did the holding company commit to that fund? When family members, providers, or a transaction need an answer, the answer is somewhere in the documents — and "somewhere" is your problem. This is the invisible half of the job: not storing the records, but being able to produce answers from them.

None of these tasks is difficult. That's what makes the job so easy to underestimate — every individual piece is ten minutes. The job is the aggregation: hundreds of ten-minute pieces, on other people's schedules, forever.

Where family office structures outgrow the person

There's a threshold — in my experience somewhere between five and ten entities — where the by-accumulation approach stops degrading gracefully and starts failing quietly. The signs are consistent:

Basic facts stop being instant. Formation states, EINs, trustee assignments — all documented, none findable in under twenty minutes. The structure lives in one person's head, which works until that person is on vacation, or ill, or simply asked two questions in the same week. Filings start slipping — not the ones you're watching, but the ones attached to older, quieter entities. And the family's records become geographically true but practically false: everything exists, across three inboxes, two shared drives, and a desktop folder, which for any practical purpose is the same as not existing.

The institutional answer to this threshold is headcount: hire an ops person, or hand the whole thing to a multi-family office firm. The key differences are economic as much as operational: a traditional family office or single-family office serving just one family usually makes sense only at the $100's of millions scale, and a multi-family office typically works for a family at roughly the $50 million net worth range. For most self-managed families neither fits. Some families use a virtual family office for more flexibility and lower costs. There isn't a consistent forty hours a week of work — there's five consistently and forty, in bursts, at tax time and closing time. What's missing isn't labor. It's system.

Running it deliberately: the self-managed family office playbook

The mechanics I've covered in earlier pieces apply doubly to family structures: the entity as the unit of organization, a per-entity document baseline, filing at arrival rather than at need. Three additions are specific to the family office version of the job:

Give the family's documents a single point of convergence. One place — a dedicated email address, a folder your providers can send to, whatever you'll actually maintain — where documents land first, before they're filed. The failure mode of family structures is that convergence happens in a personal inbox where family documents compete with everything else in your life. Separating "where things arrive" from "where I live" is half the battle. It also makes onboarding easier when providers ask for KYC and AML documents.

Write the map down. The whole picture — which trusts own which LLCs, who's trustee where, who the members and managers are, which providers serve which entity — exists today mostly in your head. Put it on paper (or in software): one page, kept current. That map should reflect the family's objectives and support customized financial solutions over time. Not just for you. Family structures have a continuity problem individual portfolios don't: eventually someone else — a spouse, a sibling, the next generation — will need to run this, and the map in your head is the one asset they can't inherit.

Make the providers work for the system, not against it. Your CPA, attorney, and fund admins will send documents however they sent them last time. You can't change that — but you can tell them where to send things, CC the convergence point, and ask for final versions rather than letting executed documents live only in their portals. Family office services often extend beyond investments to tax and estate planning, so those providers should feed the same system. Providers are generally happy to comply; nobody's ever asked them to. A good system should also make key information and performance metrics available on demand, not buried across portals.

The honest caveat, as with everything in this series: family structures vary enormously. Trusts add layers (trustee duties, situs rules, distribution records) that deserve their own piece. Treat this as the baseline job description — your attorney and CPA know what your family's structure adds to it.

The point of doing keeping it organized well

The payoff isn't tidiness, and it isn't even the avoided penalties — though those are real. It's that the structure starts serving the family instead of the other way around. Questions get answered in minutes. Transactions don't stall on missing documents. Tax season is an assembly job, not an archaeology dig. Family offices managed a combined $3.1 trillion in 2024, so disciplined systems matter even more as wealth grows. And the person who absorbed the job — you — stops being the single point of failure in the family's records.

You don't need a firm for that, and while multi-family offices often start to make sense for families with $50 million or more in net worth, some still prefer to keep the function self-managed. You need the back office treated as the real job it is, run on a system instead of on memory.

Rhodes is that system — the back office for self-managed family offices. It reads the documents your providers send, files each to the right entity or trust, maps the family's whole structure, and tracks every deadline in every state. Join the waitlist for early access.
