Blocked Persons: What a Listing Does to Property and Dealings
A designation does not take anyone's property. It stops the property from moving, and it makes almost every dealing with the listed person unlawful for anyone within United States jurisdiction. Those are two different prohibitions with different consequences.

The rule in short
Under the International Emergency Economic Powers Act at 50 U.S.C. 1701 to 1707 and the regulations in 31 CFR Chapter V, property and interests in property of a designated person that come within the United States or within the possession or control of a United States person are blocked. Blocked property may not be transferred, paid, exported, withdrawn or otherwise dealt in. Holders must report blocked property and rejected transactions within the periods the regulations fix.
A designation under a United States sanctions program produces two distinct legal effects, and confusing them causes most of the mistakes. The first is blocking: property is frozen where it sits. The second is a prohibition on dealings: United States persons may not transact with the designated person at all. A holder can comply with one and violate the other.
What blocking actually does
The authority comes from the International Emergency Economic Powers Act, which permits the blocking of property and interests in property in which a foreign country or a foreign national has an interest, where that property is subject to United States jurisdiction. The implementing programs sit in 31 CFR Chapter V, each with its own part and its own scope.
Blocking is not confiscation. Title does not pass to the government. The property remains the designated person's, and it is simply immobilized: it may not be transferred, paid, exported, withdrawn or otherwise dealt in. Blocked funds must be placed in an interest-bearing account at a United States financial institution, so the value is preserved rather than eroded while the designation stands.
The distinction from forfeiture matters legally as well as practically. Blocked property can be released if the designation is removed or if an authorization permits a transfer, and it remains on the owner's balance sheet throughout. Forfeiture, by contrast, changes title and requires its own proceeding. Confusing the two leads holders to write off assets that are merely frozen.
The prohibition on dealings
The second effect is broader than the first and is what usually catches ordinary businesses. United States persons are prohibited from engaging in transactions with a designated person: selling to them, buying from them, providing services to them, or receiving services from them. The prohibition extends to the provision of anything of value, which reaches unpaid services, discounts and forbearance as readily as it reaches cash.
Because the prohibition attaches to the person rather than to any particular property, it operates even where nothing is blocked. A consulting firm with no funds of the designated person in hand still may not do the work. The reach of these prohibitions to affiliates and to non-United States parties is treated in facilitation and the reach to non-United States parties.
Two consequences follow that are easy to overlook. Existing contracts do not carry an exemption; performance stops when the counterparty is designated, and a wind-down usually requires an authorization that is time limited. And the prohibition covers receiving as well as giving, so accepting payment, goods or services from a designated person is prohibited in the same way as providing them. Businesses that focus only on outbound flows regularly miss inbound exposure.
If a blocked person has an interest in the funds, the transaction must be blocked and the money held. If the transaction is prohibited for some other reason, with no blocked interest present, the correct response is to reject it and return the funds. Returning money in which a blocked person holds an interest is an unlicensed transfer of blocked property. Blocking funds that should have been rejected wrongly deprives a legitimate party of its money. Each outcome carries its own report.
Choosing between blocking, rejecting and licensing
| Situation | Correct response | Where the money goes | Report required |
|---|---|---|---|
| Designated person holds an interest in the funds | Block | Blocked interest-bearing account | Blocked property report, then annually |
| Prohibited destination, no blocked interest | Reject | Returned to the sender | Rejected transaction report |
| Conduct covered by a general authorization | Process the transaction | Normal settlement | Only as the authorization itself requires |
| Conduct authorized by a specific license | Process within the license terms | Normal settlement | As the license conditions require |
| No prohibition applies | Process normally | Normal settlement | None |
The reporting duties that follow
Section 501.603 requires holders of blocked property to report it. An initial report is due within a short period after the property is blocked, and a comprehensive annual report follows, covering holdings as of the date the regulation fixes. The obligation continues for as long as the property remains blocked, and it belongs to the holder rather than to the owner.
Section 501.604 imposes the parallel duty for rejected transactions. That duty has broadened over time and now reaches rejections outside the banking sector, so a company that declines an order because of a sanctions prohibition may have a filing obligation it does not expect. Section 501.605 adds a reporting duty concerning litigation, arbitration and other dispute resolution proceedings involving blocked property.
Recordkeeping runs alongside. Records of blocked property, rejected transactions and licensed activity must be kept for the period the regulations specify and produced on demand. In practice the records are what determine whether an eventual enforcement inquiry is short or long.
The duties fall on whoever holds the property, which is often a party with no relationship to the underlying dispute. A bank that stops a wire, a warehouse holding goods, an insurer sitting on unpaid proceeds and a transfer agent holding shares are all holders. None of them chose the exposure, and each is nonetheless responsible for the report, for maintaining the blocked account and for refusing instructions from the owner. Contracts rarely address who bears the administrative cost of that position.
Challenging or removing a designation
A designated person may petition the administering office for administrative reconsideration under the delisting provisions of Part 501. The petition argues either that the basis for designation was mistaken or that the circumstances have changed: ownership sold, control relinquished, conduct ceased. The process is documentary and can be slow, and the office may ask questions in writing over an extended exchange.
Judicial review is available but narrow. Courts examine whether the agency acted arbitrarily on the administrative record, much of which may be classified and summarized rather than disclosed. The standard of review questions this raises are the ordinary ones described in mixed questions and which standard applies. Where a designated entity is not itself listed but is owned by one that is, the analysis instead runs through the fifty percent ownership rule, and any dealing a party hopes to continue has to be tested against the general authorizations and how to read them.
Points to carry away
- Blocking freezes property in place; title remains with the owner and the government does not take it.
- United States persons are prohibited from dealing in blocked property or transacting with a designated person.
- Funds that are blocked must be held in an interest-bearing account at a United States financial institution.
- A holder must report newly blocked property within the period the regulations specify.
- Transactions that are rejected rather than blocked carry their own separate reporting duty.
- An annual report of blocked property is required from every holder while the property remains blocked.
Questions readers ask
Who has to comply with a blocking prohibition?
United States persons, wherever located, plus anyone dealing with property that is physically in the United States. A United States person includes citizens and permanent residents anywhere in the world, entities organized under United States law including their foreign branches, and any person actually in the United States. Some programs extend further, reaching entities owned or controlled by United States persons and abroad. The reach is defined program by program, so the first step in any analysis is identifying which part of Chapter V applies.
What happens to a payment that is stopped mid-transfer?
It depends on why it was stopped. If a blocked person has an interest in the funds, the intermediary must block the payment, place it in a blocked interest-bearing account and report it. If the transaction is prohibited for another reason, such as a country-based prohibition where no blocked person has an interest, the intermediary rejects it and returns the funds to the sender, then files a rejected transaction report. Treating a blockable payment as a rejection is one of the more common compliance failures.
Can a blocked person be paid for goods already delivered?
Not without authorization. The prohibition covers payment as well as transfer, so an obligation that was lawful when incurred cannot be discharged once the counterparty is designated. The debt itself does not disappear, and the funds are typically placed into a blocked account where they remain the property of the designated person. Parties in this position apply for a specific authorization, and the application has to explain the underlying contract and why the payment should be permitted.

Which Agency Controls a Product
Defense articles and defense services described on the United States Munitions List at 22 CFR 121.1 are controlled under the International Traffic in Arms Regulations, administered under authority of 22 U.S.C. 2778. Items not described there may be subject to the Export Administration Regulations at 15 CFR 730 to 774. The order of review in 22 CFR 120.11 directs a reader to the munitions list first, and a commodity jurisdiction request resolves genuine doubt.
End-Use, End-User and Red Flag Screening
The export rules impose prohibitions that operate independently of an item's classification. Restricted party lists identify entities to which specified transactions require authorization or are denied outright. End-use prohibitions in 15 CFR Part 744 apply where an exporter knows or has reason to know that an item is intended for a prohibited use or user. Knowledge includes awareness of a high probability, so unresolved warning signs can supply the required state of mind.
Applying for a Specific License
Where no exemption or general authorization covers conduct that a sanctions program prohibits, the route is an application for a specific license under 31 CFR 501.801 and 501.802. The application must identify the parties, describe the transaction in full and attach supporting documentation, and the office may require further information before deciding. A license authorizes only the described activity, on the conditions stated, and does not excuse conduct that has already occurred.
