Dispute Resolution

Hundreds of firms offer litigation services, but very few regularly try cases in court.


While we are prepared to settle or mediate your legal matter, we do not shy away from a trial if it best serves your interests. We pride ourselves on the ability to evaluate cases before deciding how to proceed or spending a large sum on legal fees.

Since 1990, Calvert Law Firm has secured fair and just remedies for businesses and individuals.

In fact, in 2008 Calvert Law Firm collected the largest punitive damages award in Oklahoma history for two families who had been mistreated by the practices of oil and gas companies.

stand up for your rights.

We have successfully represented clients facing a wide range of disputes, including breach of contract, business disputes, complex commercial litigation, condemnation, fraud, insurance bad faith, stockbroker misconduct, oil and gas disputes, and white collar crime.

No Guarantee of Results. Some of the case summaries, reports of past results and individual lawyer biographies on this website describe past matters handled for clients of the Firm. These descriptions are meant only to provide information to the public about the activities and experience of our lawyers. They are not intended as a guarantee that the same or similar results can be obtained in every matter undertaken by our lawyers. You must not assume that a similar result can be obtained in a legal matter of interest to you. The outcome of a particular matter can depend on a variety of factors—including the specific factual and legal circumstances, the ability of opposing counsel, and, often, unexpected developments beyond the control of any client or lawyer.
