A savings or checking account that sits untouched long enough gets classified as dormant, and eventually the money leaves the bank for a state treasury. The process has a name, escheatment, and a timetable set by state law. It happens to old accounts far more often than customers expect, usually after a job change, a move, or a forgotten joint account from years ago.
Banks must attempt to contact the owner at the last known address before handing anything over. The good news: finding and reclaiming the money is straightforward in most states, and searching is free.
The whole sequence runs on public records, so it pays to check every few years.

Dormancy, fees, and the warning letters
An account counts as dormant after a set stretch with no customer-initiated activity, typically one to three years depending on the state and the account type. Deposits, withdrawals, and logins may all count as activity; interest posted by the bank usually does not. Once dormancy sets in, some banks charge a dormant-account fee in the range of $5 to $10 a month, which slowly eats the balance.
Before the account moves anywhere, the bank must attempt to notify the owner at the address on file. Those letters get overlooked. A statement that suddenly stops arriving is the quiet warning sign.
Escheatment: the money moves to the state
After the dormancy period runs out, the bank reports the account to the state as unclaimed property and transfers the balance to the state treasury. The account closes. Every state operates these escheatment laws, and their goal is to keep idle money from being absorbed by the bank itself.
The state holds the funds indefinitely, and the claim stays with the owner for years or decades. Interest is generally not added while the state holds the money, so the recovered amount is usually the balance on the day the account was handed over.
How to find and reclaim it
Every state runs a free unclaimed property search website, and the National Association of Unclaimed Property Administrators links to all of them at unclaimed.org. A multistate tool at missingmoney.com covers participating states at once. Search under every name you have used and every state you have lived in.
Filing a claim is usually done online: submit identification, confirm the address tied to the account, and wait. Processing times vary widely, from a few weeks to a few months. State treasuries handle these claims as routine paperwork with no fee. Any site that charges a finder’s fee for this can be skipped.
It takes about ten minutes to search. Old 401(k)s and utility deposits show up in the same databases, so the search turns up more than bank accounts.
