Approximately six years ago I was in need of a lawyer in Oklahoma to represent me regarding an Oil and Gas Lease Agreement left to me by my deceased father. I live in Oregon and have not resided in Oklahoma since 1962.

It was obvious I would need help and was very fortunate to have a referral to Tom Williams! To date we have never met but he has stepped up and represented me and also other family members in various locations.

He has been efficient, fair and responsible for us and I would highly recommend him! All of our business had had to be done over the telephone or via computer and even with the time difference it has worked well.

I reached out to Jim Tack regarding an inherited oil working interest. He responded to my question within 20 minutes and I received pertinent information regarding my question. The next day he was kind enough to answer more questions that I had regarding the same issue and all of the time he spent was considered a consultation. Beyond the valuable information he shared he was also very understanding and took time to explain terminology I was unfamiliar with as well as operating concepts. Thank you Jim!!

I had not used a lawyer in years and was apprehensive about getting a lawyer to help recover some mineral rights money from deceased relatives. Mr. Williams was wonderful to work with and seems to be consistently on top of everything. He kept us informed on every step along the way. We were so grateful for his help. He was even able to push things through the probate court before the virus shut down things. I would definitely recommend Thomas Williams to anyone who needs legal assistance.

Doing business from Fort Worth Texas for property in Oklahoma was made so very easy with Tom Williams. He was kind and personable to work with and made what could have been a mess into a great experience with great outcomes. Never did I have to worry if things were being done correctly with the help he gave me. Thank you to all involved.

I am pleased to recommend Ilana Sharpe for all your estate planning needs. I had known for years that we needed to prepare for the future, but it’s not a fun topic and I kept putting it off. If only I had known how easy it would be to work with Ilana, I’d have checked this off my list a long time ago. From our first meeting, she put us at ease and helped us understand our options. She made our responsibilities clear and stayed in communication to make sure the work was completed in a timely manner. Within a matter of weeks, we had an estate package in place, and I sleep easier knowing that we will not put undue burden on our family if the unthinkable occurs.
