Business Services

Based in Oklahoma City for more than 20 years, Robertson & Williams provides legal services to business clients throughout the United States. Our legal team offers renowned expertise in a wide variety of business law matters, including:

Oil & Gas

A significant portion of the Robertson & Williams business practice focuses on assisting clients in the oil and gas industry. With a comprehensive understanding of America's oil and gas business and the complexities of government regulation, our attorneys have been representing oil and gas companies for decades. This area of our practice also encompasses the acquisition of all types of interests in oil, gas, and other natural resources. Our clients regularly rely on our seasoned ability to secure these rights and further profit strategies. Our attorneys also assist clients with transactions involving oil and gas securities offerings, mergers and acquisitions, as well as any associated litigation. By providing efficient and cost-effective legal services, we maximize the positive impact on clients' businesses and earn their satisfaction, establishing mutually successful, long-term relationships.

Business & Corporate

Our firm's expertise extends to business representation, securities transactions, and litigation. We also provide clients with guidance and representation in commercial real estate matters and commercial litigation. For corporate clients, our attorneys assist with governance and contractual matters, mergers, acquisitions, and divestitures. We also help business clients with incorporation, or the formation of other business entities, such as limited liability companies and partnerships. Our attorneys assist business clients in all areas of contract negotiations, as well as any disputes arising from contract performance.


Robertson & Williams' franchise law attorneys have extensive experience in representing franchisors and franchisees. Franchise and distribution law involves intricate regulatory standards and enforcement policies. We offer a full range of services in all phases of the franchise development, registration, and negotiation process. We advise and counsel clients on franchise law issues, including FTC and state franchise law registration and disclosure compliance. We work closely with IP counsel for federal and state trademark and service mark registration.


Filing for bankruptcy need not spell disaster for a business and its stakeholders. At Robertson & Williams, we regularly file Chapter 11 business reorganizations for our clients to allow them to reformulate a profit strategy and retain as many assets as possible. We understand the difficulties of managing a business alongside a bankruptcy filing. To ease the burden on our clients, our attorneys will draft the written disclosure statement and plan of reorganization, maintaining constant communication with the client to facilitate an informed business decision. Streamlined and cost-effective legal representation throughout the filing process is the paramount aim of our bankruptcy practice.

Commercial and Business Litigation

When commercial and business disputes arise, Robertson & Williams' clients have strong advocates acting on their behalf. Our attorneys are licensed in Oklahoma and have represented clients in district and appellate courts in Oklahome as well as Federal district and appellate courts throughout the United States. In addition, our attorneys have also served as outside counsel to the Federal Deposit Insurance Corporation (FDIC) in Oklahoma for many years. We are an approved minority (native American) firm for the FDIC.
