Domain Name Purchase Agreement

A Domain Name Purchase Agreement in the United States records the terms on which a buyer acquires the assets, fixing price, conditions and completion.

A domain name registration is a contractual right, not a property right in the traditional sense. The registrant holds an exclusive license to use a specific domain name under the applicable top-level domain (TLD) registry — such as Verisign for .com and .net domains, or Public Interest Registry for .org — for a renewable annual term. The ICANN Registrar Accreditation Agreement (RAA) governs the relationship between registrars (such as GoDaddy, Namecheap, Network Solutions, and Cloudflare Registrar) and ICANN. An ICANN-accredited domain name transfer policy, published in the ICANN Transfer Policy effective 2024 revision, governs the technical and procedural requirements for transferring a domain between registrant accounts or registrars.

Domain names can be extremely valuable commercial assets. Premium dictionary-word .com domains have sold for record prices: voice.com sold for $30 million in 2019, sex.com sold for $13 million in 2010, and fb.com was acquired by Facebook for $8.5 million in 2010. Even mid-market domain names in the $10,000 to $500,000 range represent significant transactions that justify formal written purchase agreements, ICANN-accredited escrow services, and legal due diligence.

The Domain Name Purchase Agreement serves a different function from a trademark assignment agreement. Domain names and trademarks are separate legal instruments: a domain name gives the registrant the right to use a specific internet address, while a trademark (registered with the USPTO under 15 U.S.C. § 1051 et seq.) gives the owner the right to use a word, phrase, or logo in commerce to identify the source of goods or services. Where a domain name incorporates a trademark, the seller must separately assign the trademark through a written trademark assignment recorded with the USPTO's Assignment Division — the domain name purchase agreement does not transfer trademark rights. The Anti-Cybersquatting Consumer Protection Act (ACPA), 15 U.S.C. § 1125(d), creates a private right of action for trademark owners against parties who register domain names in bad faith — a seller's representations and warranties about third-party trademark rights are therefore a critical component of the purchase agreement.

A Domain Name Purchase Agreement is needed whenever a domain name is bought or sold for any amount that requires documentation, protection of both parties, or formal transfer procedures — which in practice means virtually all private domain name sales.

Premium domain acquisitions — purchases of dictionary words, short alphanumeric strings, or established brand-matching domains in the $5,000 to multi-million dollar range — require formal purchase agreements to document the purchase price, escrow arrangement, transfer timeline, and IP warranties. Escrow.com, the ICANN-accredited escrow service used in the majority of domain name transactions, requires a transaction to be documented with an agreed description of the domain and purchase price before funds are released.

Startup and brand acquisitions frequently involve purchasing the exact-match domain for a new company or product name. When a Delaware C corporation or California LLC is incorporated with a name and a founder discovers the matching .com is held by a third party, negotiating a domain name purchase and executing a proper purchase agreement protects the startup from a failed transfer after payment.

When a domain name is part of a broader asset acquisition — for example, the purchase of an e-commerce business, a media company, or a SaaS product that relies on a specific domain — a standalone domain name purchase agreement is needed in addition to the main asset purchase agreement, because ICANN transfer procedures require specific technical steps separate from the general asset transfer.

Cross-border domain transactions — where the seller is located outside the United States or the domain is a country-code TLD (ccTLD) such as .uk, .de, .au, or .ca — require extra care because each national registry has its own transfer rules. A written agreement specifying the governing law (typically the buyer's jurisdiction or a neutral jurisdiction), dispute resolution mechanism (ICANN UDRP or litigation), and escrow arrangement is essential when the parties are in different countries.

Domain name transfers triggered by inheritance, divorce, or business dissolution also benefit from formal purchase or transfer agreements to document the consideration (or lack thereof) and provide clear instructions for the technical transfer to the WHOIS-registered owner's estate or the court-ordered transferee.

A complete Domain Name Purchase Agreement for a US domain name transaction must address the following elements to protect both the buyer and seller and satisfy ICANN transfer requirements.

Domain identification: The agreement must precisely identify the domain name being transferred, including the full domain name (e.g., example.com), the TLD registry (Verisign for .com), the current ICANN-accredited registrar, the current WHOIS registration name, and any related domain variants being transferred in the same transaction (e.g., example.net, example.org). Ambiguity in the domain identification can result in disputes about what was sold.

Purchase price and payment: The agreement must state the total purchase price in US dollars, the payment method (wire transfer, ACH, or credit card through an escrow service), and whether the parties will use an escrow service. ICANN-accredited escrow services — particularly Escrow.com — provide a secure mechanism under which funds are deposited before the transfer process begins and released only upon confirmation of successful transfer. The agreement should specify which party bears the escrow service fee.

Transfer procedure and timeline: The agreement must set out the specific steps and timeline for the domain name transfer. For gTLDs, this requires: the seller unlocking the domain at the current registrar; the seller obtaining and providing the EPP/authorization code within a specified number of days; the buyer initiating a registrar transfer request; the transfer completing within the 5-day ICANN transfer window; and the buyer confirming successful transfer to trigger escrow release. The agreement should specify what happens if the transfer fails or if the registrar imposes a transfer lock.

Seller representations and warranties: The seller must warrant that: they are the sole legal owner of the domain and have full authority to sell; the domain is free of all liens, UDRP proceedings, and pending trademark claims; the WHOIS registration information is accurate and reflects the actual registrant; the domain is not subject to any registrar lock due to a regulatory or ICANN compliance matter; and the seller's use of the domain has not infringed third-party trademark rights to the best of the seller's knowledge. These representations are critical — a buyer who receives a domain subject to a UDRP proceeding or trademark claim may lose the domain after paying for it.

Intellectual property provisions: The agreement must address whether any trademark rights, website content, or associated goodwill are included in the sale. If the sale is limited to the domain registration only (as is common in bare domain transactions), the agreement should expressly state this. If associated trademark registrations or pending USPTO applications are included, a separate trademark assignment form must be prepared and recorded with the USPTO Assignment Division under 37 C.F.R. § 3.11.

Governing law and dispute resolution: The agreement should specify the governing state law (commonly Delaware, California, or New York for US parties), the method of dispute resolution (litigation in a specified court or ICANN UDRP arbitration for disputes involving trademark claims), and a mechanism for addressing transfer failures or seller non-performance.
