Just Criminal law is an excellent team. I was very fortunate to have them representing me. I highly recommend them.
Marcus F
Great law firm. Very pleased with the communication and outcome. Thank you Maureen, Sara and Paige for all of the assistance. 10/10 experience.

Just Criminal Law was the best decision I made to help me with my DUI. I was visiting Cody Wyoming and made a bad judgment decision and drove back to my hotel after dinner & drinks. I was pulled over and arrested for DUI. I contacted Just Criminal Law. The consultation was really helpful and informative, they gave me a timeline and cost. I was well informed every step of the way. I paid the fee up front and thought the fee was very reasonable for my situation. Sara, my lawyer was very helpful and even seemed to care about me and getting me the best outcome possible. At the end at court the judgment was a reasonable verdict and one that didn’t end my career or take my driving privileges away. I highly recommend Just Criminal Law to represent anyone in need of a good lawyer to navigate the laws and courts on your behalf.

⭐⭐⭐⭐⭐ Exceptional attorney Sara Lock and exceptional results with all of her team working with her and beside her. From our first meeting, it was clear that this lawyer was experienced, confident, and fully invested in achieving the best outcome possible. Their preparation, courtroom presence, and ability to navigate complex legal issues were truly impressive. Throughout the process, I always felt informed and knew I had someone fighting tirelessly on my behalf. The outcome they achieved was life-changing, and I will be forever grateful. I recommend them without hesitation to anyone seeking top-tier legal representation.

I, unfortunately needed an attorney. Members of Just Criminal Law listened to my side, viewed what proof I had and began building my defense. The was kept informed of the progress and I my case, I went from possible jail and suspended license to only a $105 fine! My case might not look like yours but if you are in need of a defense attorney I strongly recommend Just Criminal Law to defend you.

They worked with me and highly recommend this law firm if you’re in any trouble out of state! I was unfortunately pulled over for speeding and got caught with marijuana and I am from California where it’s legal and I didn’t know that the state of Wyoming was illegal for recreational and medical use. I didn’t know that it can end up as a misdemeanor and me coming from California. It was a huge surprise.! Ended up calling this law firm and they called me back within less than 24 hours taking my case seriously. Highly recommend Sara .L and Maureen Who has helped me throughout this progress and a big shout out to Paige for answering my calls and questions when needed. I thought this experience was going to be a rough time Cause I am from California and this was a Wyoming case. With that being said, I do not have a criminal record or a misdemeanor on my record. They had worked with the court and the paralegal to give me a good reasoning if you’re traveling from another state and you get caught with any reason, please contact this law firm they were amazing, friendly fast and I would highly recommend this to my friends and family in the future. Thank you again! Tiren H

We were a little impatient, but Just Criminal kept us calm and informed during the whole process. Would recommend 100% and already had a friend get a free consultation.
Janaye D
Everyone at Just Law was wonderful! I initially called on a Sunday, not expecting to be contacted until the next day, but I received a call about 2 hours after that! I was scheduled for the next day, and it took off from there. Everyone was so nice and understanding as I sat blubbering in the office. I was so grateful for their kindness and compassion, as well as how hard they worked to get me the best deal. Special shout-out to Sarah for the time she spent going to bat for me, and explaining everything so I could understand what was happening or going to happen. Thanks for everything!!
Phillip M
Would highly recommend. Great people to work with.
