How to run due diligence before buying a .us domain

A .us domain is on the table. The price looks right, the name is clean, and the seller is pressing for a quick close. Before any transfer of funds, one question should pause the transaction: what is the actual legal history of that registration? A domain that carries a prior dispute, a trademark conflict, or a tainted chain of title can become a liability the moment it lands in your account.

To run due diligence before buying a .us domain, a buyer must verify three things: that the seller holds clean title with no pending or decided usDRP proceeding against the name, that the domain does not conflict with a registered or common-law trademark capable of supporting a new complaint, and that the transfer will be structured through a proper escrow so funds and the domain change hands simultaneously. The usDRP – the .us Dispute Resolution Policy – is the governing arbitration mechanism for .us, and a prior adverse decision or an undisclosed pending proceeding can strip a new registrant of the name as quickly as it stripped the last one.

This page covers the usDRP rules that shape .us domain risk, the due-diligence steps that reveal it, the escrow structure that contains it, and the realistic next step for a buyer who wants certainty before closing.

What is the usDRP, and why does it matter before you buy?

The usDRP is the arbitration policy that governs .us domains, administered by the National Arbitration Forum under a mandate from the .us Registry. It closely tracks the UDRP's three-element test but carries a critical structural difference that affects every acquisition.

Under the usDRP, a complainant must show: (1) the domain is identical or confusingly similar to a mark in which the complainant has rights; (2) the registrant has no rights or legitimate interests in the domain; and (3) the domain was registered or is being used in bad faith. That third limb reads "registered or used in bad faith" – a disjunctive standard. Under the UDRP it is "registered and used in bad faith," a cumulative burden. The practical consequence is significant.

A domain registered years ago without apparent bad intent can still lose a usDRP proceeding if it is currently being used in a way that a panel finds abusive. A buyer who acquires such a domain and points it at a new commercial website may provide the "use" element that was previously absent. The prior owner's innocence does not travel with the registration. This is not a theoretical risk. We regularly advise buyers who discover, after closing, that a name they purchased in apparent good faith immediately attracted a complaint from a brand owner who had been waiting for a bad-faith use event to crystallize.

The only remedies under the usDRP are transfer or cancellation – no monetary damages, no injunction. That means a successful complainant takes the domain, and the buyer who paid for it is left with nothing but a claim against a seller who may be unreachable.

How do you check chain of title for a .us domain?

Chain-of-title review for a .us domain starts with the current RDDS (registration data) record and works backward through every ownership change the domain has experienced.

The first step is a current RDDS query against the .us Registry to confirm that the named registrant matches the seller and that the domain carries no registrar-lock status inconsistent with a voluntary transfer. A domain that is locked due to a pending dispute or a registrar hold cannot be cleanly transferred until that hold is resolved. Confirm the registrar of record and verify that no DISPUTE notation or equivalent block has been placed against the name.

The second step is a historical WHOIS review. Several commercial services maintain historical RDDS archives. These records reveal every change of registrant, registrar, and contact data across the life of the registration. A domain that has cycled through multiple registrants in a short window, or that shows an abrupt registrant change shortly before the sale, warrants close scrutiny. Rapid registrant turnover is a classic indicator of either a dispute-avoidance maneuver or an account-compromise event.

The third step is an archived content review. Web archive services capture the historical content that a domain has served. If the domain previously resolved to content that mimicked a trademark owner's website, directed traffic to a competitor, or carried pay-per-click links on third-party brand terms, that history is available to any future complainant's counsel – and to any usDRP panel. The domain's past use is not reset by a change of ownership.

The fourth step is a prior-dispute search. A review of published usDRP decisions – the National Arbitration Forum maintains a public database – will reveal whether the domain has previously been the subject of a proceeding. An adverse decision already entered against the name is the most severe discovery: it means a panel has already found bad faith, and a new registrant is acquiring a name with that finding on the public record. That finding does not automatically bind a new proceeding, but it is powerful evidence that a future complainant will use.

What trademark conflicts should a buyer identify before the .us transfer?

A trademark conflict does not have to be active litigation to represent a genuine acquisition risk. The relevant question is whether any party holds rights in a term identical or confusingly similar to the domain, and whether the buyer's intended use would constitute the "use in bad faith" element that completes a usDRP claim.

Begin with the USPTO trademark register. Search both the exact domain string (without the .us extension) and plausible phonetic equivalents. Identify live registered marks, pending applications, and recently expired marks that remain within the opposition or grace period. A pending application does not yet carry the presumptive rights of registration, but panels have recognized common-law trademark rights where the evidence of use is clear, and a pending mark can become a registered one during the ownership of the domain.

Extend the search internationally. A brand owner with a US federal registration is the most obvious claimant, but a foreign trademark holder with a nexus to US commerce can also bring a usDRP proceeding. The usDRP does not limit standing to US registrants or US trademark holders.

Consider the buyer's intended use. Panels consistently hold that a new registrant's intent at the time of acquisition is relevant to the bad-faith analysis. A buyer who plans to use a domain for a legitimate, non-competing service, and who documents that intent before the transfer, is in a materially stronger position than a buyer who acquires first and decides later. We advise clients to memorialize the intended use in writing – a business plan excerpt, a registered entity name, a domain-use memo – before the purchase is complete. That contemporaneous record is among the most useful pieces of evidence in any subsequent usDRP defense.

How should the transaction be structured through escrow?

The escrow structure for a .us domain acquisition serves two functions: it protects the buyer against non-delivery of a domain that has been paid for, and it provides a contractual window for due-diligence conditions to be satisfied before funds are released.

A proper domain escrow holds the purchase funds in a neutral third-party account. The seller initiates a registrar transfer of the domain; the buyer confirms receipt and technical control; only then are funds released to the seller. The registrar's five-day transfer window – sometimes longer, depending on the registrar's process – creates the natural timing for a final pre-closing check. If a usDRP proceeding is filed against the domain during that window, the transfer may be locked by the registry pending resolution.

The escrow agreement should specify what constitutes a successful transfer: confirmation from the gaining registrar that the domain is registered in the buyer's name, with no active dispute or registry lock. It should also define what happens if the transfer fails – a full refund of the purchase price to the buyer without a requirement for the buyer to prove fault.

A buyer who pays for a .us domain by wire transfer directly to a seller, without an escrow intermediary, has no contractual protection if the domain is never transferred or is transferred subject to a dispute that was not disclosed. We have managed recovery efforts for buyers in exactly that position. The recovery is often possible but always more expensive than the escrow would have been. For guidance on escrow mechanics in domain transactions generally, see our guide to domain escrow for .net and gTLD transactions.

In autumn 2024, we structured an acquisition of a .us domain for a regional services firm that included a due-diligence condition: closing was conditioned on a clear usDRP-decision search and a trademark clearance memo. The seller's timeline was tight. We completed both reviews in under a week and the escrow closed without incident. The buyer's counsel had a written record of the trademark clearance before a single dollar moved.

What evidence decides the outcome if a usDRP complaint is filed after the purchase?

The evidence that decides a post-purchase usDRP complaint is largely assembled during due diligence – which is why due diligence and dispute defense are two phases of the same task.

On the complainant's side, the decisive evidence is typically: a trademark registration predating the domain's registration or the transfer event; historical RDDS data and archived web content showing that the domain was previously used to target the brand; and the buyer's commercial activity with the domain after transfer.

On the respondent's side – the buyer who is now defending – the decisive evidence includes: documentation of the legitimate purpose that prompted the acquisition; absence of any intent to sell to the trademark owner; absence of pay-per-click or third-party advertising content on brand terms; and a business use that is genuinely non-competing with the complainant's goods or services.

The Paragraph 4(c) safe harbors under the usDRP mirror those of the UDRP: bona fide offering of goods or services before notice of the dispute; being commonly known by the domain name; and legitimate noncommercial or fair use without intent for commercial gain by misleading diversion. A buyer whose intended use falls squarely within one of these categories should document that position before the transfer, not after a complaint arrives.

The "use" element of the usDRP's disjunctive standard also means that passive holding – pointing the domain to an under-construction page with no commercial activity – carries real risk. Panels have held under analogous policies that passive holding of a name that is identical to a well-known mark, by a registrant who cannot demonstrate legitimate purpose, may itself satisfy the use-in-bad-faith element. A buyer who plans to hold the domain while building a business should document the development timeline and, where appropriate, configure the domain to serve the genuine intended use as promptly as possible.

In a recent matter (a .us domain, spring 2025), a buyer engaged us for respondent defense after acquiring a two-word domain at auction. The prior owner had pointed it at a competing pay-per-click page. The new owner had immediately redirected it to a legitimate business site. We built the defense around the contemporaneous documentation of the redirected use, the absence of any trademark-targeted advertising content, and the buyer's prior written use memo. The panel found no bad faith on the buyer's part.

How does usDRP risk compare with a .com or a new-gTLD acquisition?

Every gTLD and ccTLD acquisition carries some version of the same due-diligence requirement, but the risk profile differs by zone in ways that affect the priority and scope of each check.

For a .com acquisition, the UDRP's cumulative "registered and used in bad faith" standard means that a new buyer who registers or acquires in genuine good faith and uses the domain legitimately has a stronger structural defense than under the usDRP's disjunctive test. A prior bad-faith finding against the domain still exists on the public record and will be used by any future complainant, but the "use" element must also be satisfied against the new registrant's conduct specifically.

For a new-gTLD acquisition – a .store, .online, .tech, or similar string – the UDRP applies, and the same "registered and used" cumulative standard governs. But new gTLDs also carry URS (Uniform Rapid Suspension) risk, where the standard is "clear and convincing" evidence of bad faith and the remedy is suspension, not transfer. A URS suspension does not transfer the domain but can freeze it for the remainder of the registration term. For Trademark Clearinghouse claims notices arising from new-gTLD registrations, see our TMCH claims notice service.

For a .us acquisition, the disjunctive bad-faith standard and the zone's national-character requirement create a distinct risk layer. The .us Registry requires nexus – the registrant must be a US citizen, permanent resident, organization, or entity with a bona fide presence in the US, or in some cases a foreign entity with a US nexus. A buyer who cannot satisfy the nexus requirement at the point of transfer cannot hold the domain at all, regardless of the merits of any dispute. Verify nexus eligibility before structuring the escrow.

The forum choice is also different. The usDRP is administered by the National Arbitration Forum. WIPO does not administer .us disputes. For a buyer with both a .com and a .us at issue, those proceedings run in parallel before different providers, under different standards, and with potentially different outcomes. We handle both, but we plan them separately.

What is the realistic cost and timeline for a pre-closing .us due-diligence review?

A thorough pre-closing .us due-diligence review typically covers: an RDDS and registrar-lock check, a historical WHOIS review, an archived-content survey, a usDRP-decision search, and a USPTO trademark clearance memo. The scope is proportionate to the transaction value and the complexity of the domain string.

For a straightforward single-domain acquisition – a clear two-word domain, no obvious trademark homonym, and a modest transaction price – the review is a bounded, flat-fee engagement. For a domain that has a long history, a complex trademark landscape in its industry vertical, or a prior dispute on record, the review is more intensive and correspondingly priced. We provide a fixed-fee estimate after a brief initial assessment; the due-diligence cost should be weighed against the acquisition price and the cost of losing the domain to a usDRP proceeding post-close.

A usDRP complaint, if one is filed against a domain you have just acquired, runs on the National Arbitration Forum's timetable. The respondent has 20 days from commencement to file a response. A decision typically follows within approximately two months of filing, depending on panel scheduling and any procedural complications. That is a tight window in which to assemble a defense, and the quality of that defense depends directly on the documentation assembled before the transfer.

The filing fee for a usDRP complaint at the National Arbitration Forum begins at approximately USD 1,300 for one to two domains on a single-member panel – a figure the complainant pays. For the buyer-turned-respondent, the legal fee to prepare a defense is a separate engagement, at market rates comparable to UDRP respondent work. Prevention, in the form of pre-closing due diligence, is materially less expensive than post-complaint defense.
