What Is Escheatment of an Unclaimed Brokerage Account?
Assets don’t disappear when an account goes untouched for years, but they can leave the brokerage entirely and land in the custody of a state government instead.
The short answer
Escheatment is the legal process by which unclaimed brokerage assets — cash balances, and in many cases the securities themselves — are transferred out of a brokerage firm and into the custody of a state government after an account has gone unclaimed for a legally defined period. States run these unclaimed-property programs, not the federal government, and the brokerage is generally required by law to hand the assets over once the process concludes; it doesn’t have the option of simply keeping them.
How the clock starts running
Escheatment doesn’t happen out of nowhere. It follows a period of confirmed dormancy, during which the account shows no owner-initiated activity and the brokerage’s attempts to reach the owner by mail go unanswered. Once that dormancy period runs its full course under the relevant state’s law, the account becomes eligible for the state to claim, and the brokerage moves the assets accordingly.
Which state’s rules apply
The state that governs escheatment is generally the one tied to the account owner’s last known address on file, not the state where the brokerage itself is based. Every state sets its own dormancy period and its own procedures, and those rules change over time and depend on individual circumstances, so the exact timeline for one account can differ from another simply based on where the owner used to live. If the address on file is outdated or was never updated after a move, the account can end up governed by a state the owner no longer has any connection to, which is part of why the search process later often means checking more than one state.
What actually gets transferred
Cash sitting in the account transfers as cash. Securities are handled differently depending on the state: some states direct brokerages to liquidate stock, fund, or bond positions and send over the resulting cash, while others accept the securities themselves into a state-run custodial arrangement. Either way, once assets escheat, the original brokerage relationship effectively ends — the state, not the brokerage, becomes the party holding the property going forward. The brokerage is typically required to send a final notice shortly before the transfer takes place, which is often the last realistic chance to intervene before the account leaves the firm entirely.
Why this differs from simply losing the money
Escheatment is a legal transfer, not a forfeiture. The state holds the assets as custodian, generally indefinitely, and the original owner or their heirs — sometimes identified through a listed beneficiary on the account — typically retain the right to file a claim to get them back later, even years afterward. That’s a meaningfully different outcome from an account simply being written off, and it’s the reason unclaimed-property searches exist as a routine way for people to check whether they’re owed something.
The bottom line
Escheatment exists to protect unclaimed money rather than to seize it, but reaching that point means the assets leave a familiar account and enter an unfamiliar government process, which is exactly why keeping contact information updated on every open account is worth the small effort. A brokerage account, unlike a forgotten gift card, doesn’t simply expire — it changes custodians, and knowing that distinction is what makes the difference between assuming money is gone and knowing where to look for it.
