Bitcoin left on a U.S. custodial exchange can be presumed abandoned under state unclaimed property law after a stretch of silence, usually three or five years. The legal duty sits with the exchange, not the state. It must try to reach you, then report and deliver either the coins or their dollar value to the state tied to your last known address.
The state holds what it receives as custodian. Your claim survives. Whether you get back sats or cash depends on the state, and on how long you wait.
Unclaimed property law, still often called escheat, is far older than exchanges. The 2016 Revised Uniform Unclaimed Property Act added “virtual currency” to its definitions: a digital representation of value used as a medium of exchange, unit of account, or store of value, without U.S. legal tender status. The model act largely stopped at the definition. The rules that actually matter to a bitcoiner, how long the clock runs, what resets it, and whether the state takes coins or dollars, were written state by state.
Who owes the duty
These statutes bind the holder: the business that possesses the property or owes it to someone. For a custodial exchange, that is the platform. The holder has the records, the address on file and the ability to move the asset. No state scans the chain looking for your account. It waits for the holder’s report.
Which state receives the property usually turns on the owner’s last known address in the holder’s books. With no address on file, the fallback is generally the holder’s state of incorporation, the priority scheme the Supreme Court set out in Texas v. New Jersey and that New York writes directly into Abandoned Property Law § 1319. That is how a dormant account can land in a state you left years ago.
Coinbase’s escheatment page describes the process from the holder’s side. Inactivity is measured against each state’s rules, and notices go out before any transfer. Coinbase says it seeks to deliver eligible crypto in native form where a state program can accept it. Where a state requires conversion, the owner may be entitled only to the dollar proceeds.
How the clock runs
The sequence is stable even where the numbers are not. Dormancy runs while the owner shows no interest in the account. California, Virginia and Arizona each count simply logging in as an act of ownership, along with activity on any other account at the same holder. A trade, a deposit, a withdrawal or a documented exchange with support also works.
Before delivery, the holder must attempt notice. In California, that means certified mail where a postal address exists, sent no earlier than 12 months and no later than 6 months before the asset becomes reportable. If the owner stays silent, the holder reports and delivers. From that moment, the owner’s counterparty is the state.
Four states, four answers
State | Statute | Dormancy | Delivery | When the state may sell |
|---|---|---|---|---|
California | SB 822, Ch. 660 (2025) | 3 years from returned mail, or from last act of ownership | The exact asset, unliquidated, within 30 days after the report deadline | Must convert between 18 and 20 months after the report |
New York | 5 years | To the Comptroller | As soon as practicable; claimant receives proceeds less costs | |
Virginia | HB 798, Ch. 669 (in force July 1, 2026) | 5 years | Native form where the holder controls the keys | Generally after at least one year, with exceptions |
Arizona | HB 2749, Ch. 150 (2025) | 3 years after a communication returns undeliverable | Native form within 30 days of the report | Within 3 years of receipt, never below the prevailing exchange price |
New York’s Comptroller has told holders that the five-year virtual currency clock began on November 22, 2022 for the first report, with a June 30 cutoff and delivery by November 10. On a plain reading of that guidance, the first virtual currency deliveries under § 1319 fall due in November 2028.
Other states never see a coin at all. Illinois requires the holder to liquidate within 30 days before filing its report, and the owner has no recourse for any later gain in value.
In kind is a holding period, not a promise
The phrase “in kind” has been read as a guarantee that unclaimed bitcoin stays bitcoin. The statutes say something narrower.
California does take the coins, but its Controller must convert them inside the 18 to 20 month window. Arizona must sell within three years. Virginia’s one-year floor gives way when the administrator finds an earlier sale in the Commonwealth’s interest; an owner who claims inside that year then receives the greater of the sale proceeds or the market value at the time of the claim. After the year, Virginia expressly bars any claim for appreciation after delivery.
In practice, native delivery buys the owner a window. Claim inside it and you may receive bitcoin. Claim after it and you receive dollars fixed at a sale price you did not choose.
Arizona adds a wrinkle of its own. Airdrops and staking rewards earned on state-held assets move to a Bitcoin and Digital Assets Reserve Fund once the property has sat unclaimed for three years after transfer.
Keys remain the hard limit. California, Virginia and Arizona all tell a holder that has only a partial key, or cannot otherwise move the asset, to keep it until it can. California also gives the holder 60 days to try to assemble the keys it needs.
What self-custody changes
It removes the holder. These statutes reach property held or owed by a business. Coins under keys you control have no holder, so there is no one to send the notice and no one to deliver anything.
That has not stopped other theories. A pseudonymous plaintiff, “Noah Doe,” filed suit in New York County Supreme Court in March 2026 seeking a declaration of ownership over 39,069 dormant addresses. The claim rests on New York’s lost-property statute, Personal Property Law Article 7-B, not on § 1319. Galaxy Research’s docket review traces the filings. Justice Kathy J. King stayed the case in June and barred any default judgment application. Even a favorable ruling would produce paper title, not a signature.
The Senate draft of the CLARITY Act includes Section 20216, which would bar treating a self-custodied asset as abandoned, escheated or subject to finder’s title solely because it sat inactive. Its definition requires exclusive control of the keys without any custodian or exchange, so exchange accounts stay outside it by its own terms. On September 15, a motion to proceed to the bill fell short of cloture, 49 to 50. The provision is not law.
Self-custody also cannot undo a report already made. Once the exchange delivers, you deal with the state.
What to do this month
If bitcoin still sits on an exchange, treat the account as a legal relationship with a reporting duty attached, not as cold storage with a password.
Confirm the email and postal address on file. Mail returned undelivered is often what starts the clock.
Sign in, or send support a documented message, if you mean to keep the account open. If the plan is self-custody, withdraw and verify the receiving wallet before you need the funds.
If you walked away from an account years ago, search unclaimed.org and MissingMoney.com under every name and address the exchange might have used, then file with the state that holds it. Keep old exchange statements; they are what a claims examiner asks for.
Do not rely on a three-year or five-year figure from a headline. Pull the current text for the state on your account.
The split is simple. Coins a business holds for you can be presumed abandoned and delivered. Coins only you can move cannot be delivered by anyone, because no business stands in the chain.
