How Custody Actually Works: Where the Money Sits When Your Advisor Is Independent

The short answer: When an advisor is independent, client money does not sit with the advisor. It sits at a qualified custodian, a regulated institution like Schwab, Fidelity, Pershing, or Altruist, in an account titled to the client. The custodian holds the assets, executes the trades, sweeps the cash, and sends the statements. The advisor holds a limited authorization to manage and bill the account, and nothing more. This separation is not a courtesy; it is federal architecture, built precisely so the person who advises on the money can never be the person holding it.

It is also the single most common question clients ask when their advisor considers a move: if you leave the big firm, where does my money actually go? Advisors deserve a better answer than "trust me," and clients deserve the mechanics. Here they are, at all three levels.

Firm level: what does a custodian actually do?

Start with the division of labor, because everything else follows from it.

The custodian is the vault and the plumbing. In its own words, a custodian provides for the safekeeping of client securities. Operationally that means executing and settling trades the advisor places, sweeping uninvested cash daily, processing contributions and withdrawals, and producing the official account record: statements, trade confirmations, and tax reports, sent directly to the client. At the top of the market this is enormous infrastructure; Schwab alone provides custody, clearing, and trading for $5.5 trillion in client assets across more than 16,000 independent advisory firms.

The advisor is the decision layer. An independent RIA selects investments, manages the portfolio, and plans around it, under an authorization the client signs that is deliberately narrow: typically the authority to trade the account and to deduct advisory fees. Custodians state the separation plainly in their own disclosures: independent advisors are not owned by, affiliated with, or supervised by the custodian.

The two produce parallel paper. The custodian's statement is the official record. The advisor's performance reporting arrives separately, and the SEC's own investor guidance encourages clients to compare the two documents. That redundancy is the quiet genius of the model: two unaffiliated companies, each reporting on the same account, each visible to the client directly. Which custodians dominate the market, and how they price, is its own subject; we mapped it in our guide to the independent platform landscape.

The rulebook: what does the SEC custody rule require?

The architecture above is not convention. It is Advisers Act Rule 206(4)-2, and three of its requirements do most of the work.

Client assets must sit at a qualified custodian. The rule limits who may hold advisory client assets: banks, registered broker-dealers, futures commission merchants, and certain foreign financial institutions. An RIA cannot simply hold your portfolio itself.

Custody is defined broadly on purpose. The rule treats an adviser as having custody if it holds client funds or securities directly or indirectly, or has authority to obtain them. Even the routine authority to deduct fees from an account is a form of custody, which is why the industry standardized on the minimal-custody model: assets at the custodian, advisor authority limited to trading and billing.

Verification is built in. Qualified custodians must send account statements directly to clients at least quarterly, so the official record never routes through the adviser. Advisers with custody beyond fee deduction must also submit to an annual surprise examination by an independent public accountant, an unannounced check that the assets the adviser claims to oversee actually exist where they should.

One current-events note, because advisors get asked about it: the SEC proposed a sweeping replacement called the Safeguarding Rule in 2023, then withdrew that proposal on June 12, 2025, along with thirteen other pending rules. Modernizing the custody framework appears on the SEC's Spring 2026 regulatory agenda, but nothing new has been proposed or adopted. The rule described above is the one in force.

Client level: what actually protects the money?

Safety in this system is layered, and it is worth being precise about what each layer does and does not cover.

Layer one: segregation. Under the SEC's customer protection rule, brokerage firms cannot use customer assets to finance their own business. Fully paid client securities are segregated, and client cash is held in special reserve accounts maintained for the exclusive benefit of customers. Customer assets are not subject to claims by the custodian's creditors. This is the layer that matters most and gets discussed least: even in a custodian's failure, your securities are not part of its estate.

Layer two: SIPC. If a SIPC-member broker-dealer fails and assets are missing, SIPC replaces them up to $500,000 per customer, including a $250,000 limit for cash. Every SEC-registered broker-dealer must be a member. In liquidations SIPC has handled, 99% of eligible investors have been made whole, and FINRA's guidance notes most customers of a failed firm receive their assets within one to three months. Know the boundaries: SIPC protects the custody function only. It does not cover market declines, bad advice, annuities, commodities cash, or unregistered investments.

Layer three: excess coverage. Major custodians buy private insurance above SIPC. Schwab's published program, underwritten at Lloyd's of London, provides up to $149.5 million of securities coverage per client account, with a $600 million program aggregate. FINRA's honest caveat applies: private excess coverage is only as strong as its carrier.

And the cash wrinkle: FDIC. Custodians sweep uninvested cash daily, commonly into program banks. Once there, it is a bank deposit: FDIC-insured up to $250,000 per depositor, per bank, per ownership category, and multi-bank sweep programs stack that coverage across several banks. FDIC never covers securities; SIPC never covers bank deposits. Where your idle cash sleeps, and under which regime, is a legitimate diligence question, and the economics of that cash are, not coincidentally, how "free" custody gets paid for.

What none of this insures is performance. The 2023 regional-bank scare made the distinction vivid, and we wrote about the platform-risk lessons in our First Republic analysis: custody protections are about possession, not price.

Advisor level: what changes when accounts move?

For the advisor in transition, custody mechanics compress into one system: ACATS.

The machinery. The Automated Customer Account Transfer Service, operated by the National Securities Clearing Corporation, is how brokerage accounts move between firms. The client signs transfer paperwork at the new custodian; the systems match the request against the old account; and once validated and accepted, the delivering firm has no more than three business days to move the assets. A problem-free transfer typically completes in about a week from submission, sometimes two.

What moves in kind. Cash, domestic stocks and bonds, listed options, and most mutual funds and ETFs the receiving custodian can hold transfer as-is; nothing is sold, and cost basis follows. This is why a well-run transition is not a taxable event for the ordinary account.

What does not. Proprietary products of the delivering firm, and third-party funds the receiving firm has no agreement to hold, cannot ride ACATS. Firms are required to notify clients of any non-transferable assets and offer alternatives: liquidate, leave the position behind, or handle it separately. Annuities move by their own, slower rails. Every advisor planning a move should run this analysis position by position before resigning, because portability friction is one of the four forces that decide what percentage of clients actually follow.

The advisor's honest client script writes itself from the mechanics. Your account moves to a regulated custodian, titled to you. Your holdings transfer in kind; here is the short list of exceptions and what we will do about each. Your statements will come from the custodian directly, and you can see the account there any time, with or without me. That is not reassurance; it is a description of the system working as designed.

Why this structure is the independence story

Here is the part worth sitting with. At a traditional brokerage, one company employs the advisor, holds the assets, manufactures some of the products, and produces the statements. The independent model unbundles all of it: advice at the RIA, assets at the custodian, products from the open market, verification running in parallel from two unaffiliated firms. Clients do not lose institutional safekeeping when an advisor goes independent; they keep the same custodial machinery, the same SIPC and segregation protections, and gain a second, separate set of eyes. The full decision framework around that model, economics included, lives in Going Independent: What Are My Options.

If you are an advisor weighing a move and the custody conversation is the one your clients keep asking about, we can help you build the answer for your specific book: which assets ride ACATS clean, which need handling, and how to script the client story so the mechanics do the reassuring.
