Holland & Hart LLP announced Nov. 11 that oil and gas royalty litigation and transactional attorney Rosario Doriott Domínguez joined the firm as a partner in the Denver office. Doriott Domínguez brings experience serving clients facing complex royalty audits, demands, compliance issues, transactional concerns and litigation. 

Doriott Domínguez advises oil and gas companies, ranging from small operators to multinational companies, on critical royalty reporting, payment and compliance issues. She represents payors operating on federal, Native American, state and private lands, and those operating under federal leases in the Pacific and Gulf of Mexico. 


Doriott Domínguez guides her clients through self-audits and in responding to government audits, including data mining requests, compliance reviews, enforcement inquiries and other investigations by the Office of Natural Resources Revenue, the Department of Justice, the U.S. Office of Inspector General and state departments of audit. 

She also represents clients seeking royalty refunds and disputing royalty demands, including orders to pay, orders to perform restructured accounting, civil penalties and denials of cost allocation and valuation proposals. Doriott Domínguez regularly appears before the ONRR, the Bureau of Indian Affairs, the Interior Board of Land Appeals and in federal district and appellate courts. Doriott Domínguez also advises her clients on regulatory rulemaking and on compliance with new rules and policies. 

Before joining Holland & Hart, Doriott Domínguez was a partner at Ryan Law Firm, where she led the firm’s oil and gas royalty practice. 

“We are delighted to include a partner of Rosario’s caliber to our oil and gas team,” said Emily Schilling, the firm’s environmental practice group leader, in a press release. “Rosario’s clients appreciate her painstaking attention to detail and her ability to identify and pursue opportunities for cost saving: over the years, her work has included saving producers an estimated $25 billion in costs. Her approach to developing novel legal arguments persuasive to regulators and courts aligns with our team’s longstanding focus on creative solutions that vigorously promote clients’ business interests.” 

“My clients and I are very excited about my move to Holland & Hart,” said Doriott Domínguez in a release. “The firm has a well-established reputation for excellence throughout the Mountain West on environmental and natural resources issues as well as legal and regulatory matters impacting the oil and gas industry. I’m looking forward to collaborating with the talented lawyers on these teams and the ability to offer the full breadth of the firm’s services to my clients.”
