Exceptional Divorce Attorney

I am deeply grateful to my attorney, Jennifer, for all the effort and dedication she put into handling my divorce case. She is highly professional and truly committed, always quick to understand my intentions and provide tremendous emotional support during a very difficult time. Working with her has ...been a very positive experience, and I felt fully supported throughout the entire process. Their teamwork made everything more efficient and gave me great peace of mind. I am very satisfied with their services and have already recommended them to friends who may need legal support.

Professional and Responsive

Really appreciated the whole team being straight forward and quick to respond with anything I needed. Couldn’t have asked for better representation.

LaCoste Law Review

When I first met with LaCoste Law, I came in feeling helpless and without any recourse to the situation I was in. However, that quickly changed after I had my first meeting with them. They listened to everything I was dealing with and reassured me that they would do everything they could to help me.... They are very easy to work with, and very knowledgeable in what they do. Communication is phenomenal, they walked me though every step of the process. I was never left feeling lost or unheard. If you are a father and feel like all the odds are against you, I would highly recommend that you reach out to LaCoste Law. They were able to resolve my situation with mine and my children’s best interest at heart.

"Jennifer is one of Benton-Franklin Counties leading practitioners. It's obvious how much respect she commands from the local bench and bar. What is less obvious is how much she gives back to the bar and the community in service. A first rate attorney and person."

Relationship: Opposing Counsel on matter

"Jennifer and I have opposed each other in a number of cases but only recently had to take a matter to Trial. It was nice to be able to work on focusing on the issues for a Trial instead of purposely delaying or frustrate the process. I believe it says something when you can respect the lawyer on the opposing side at the end of litigation; I would recommend her as counsel for family law issues."

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
