Proudly serving Oklahoma City since 1982

When you choose the Jim A. Lyon Law Firm in Oklahoma City, you are choosing experience. For more than 30 years, our local law firm has handled cases like yours. We know the path to take to get the results you need.

Our record of positive results includes numerous wins in complex cases, many involving estate matters and probate law issues. In one published case, 750 P. 2d. 1137, Oil and Gas Rep. 610, we appealed an oil and gas mineral rights case to the Supreme Court level and won.

We have represented major players in the oil and gas industry. We get a great deal of cases referred to us by fellow attorneys, both local and out of state, who trust us to achieve their clients’ goals. These cases often involve Oklahoma ancillary probates with oil and gas properties, complicated estate matters or other unique and complex issues.

We keep abreast of changes in the law, are sensitive to our clients’ needs, and are committed to always working at the highest level of professionalism and integrity. Our law firm will give your case the personal attention it deserves and provide legal representation in a timely manner at affordable rates.

We will work with you to create the most appropriate legal strategy based on the situation and your goals. That may mean negotiating a resolution. It may also mean taking the matter to trial.
