Case against abusive Ex

This will be a long review, but if you’re in a tough spot feeling like you have no hope…. Read on. I found Katie after 4 other lawyers told me nothing could be done with my case. My ex had been abusive in every way that one could be. Every form of domestic abuse. That included financial abuse. ... He forced me to sign over every marital asset for my freedom. I did this, as it beat the other option. A year later, as I was rebuilding my life, he tried to take the kids away from me, having me seen as an unfit mother. Not only did Katie fight that, she was able to turn the tables on him. She knew that we needed to prove his mental status and the danger that that posed for the children’s mental, emotional, and physical well being. I was deathly scared of him and what he was capable of. I had been sufficiently gaslighted during the entire marriage, I truly feared him. Katie calmly guided me through the whole process, but was a pitbull when it came time to deal with him. I could have sold ring-side seats to his deposition. Not only did we gain primary custody, all decision making for the kids best interest, he now had to pay ME child support AND we recovered some of my attorney fees. I have recommended Katie many times, and I personally know of 2 other “tough” cases that she has been able to win for her clients (friends of mine).

High Conflict Case, Exceptional Outcome!

I cannot say enough good things about Katie Leonard. If you are looking for an attorney who is strategic, prepared, confident in the courtroom, and truly cares about her clients, she is the one. My case was extremely high conflict. I was hit with a false TPO that forced me out of my own home and a...way from my daughter. As a very involved father and my daughter’s softball coach, that was devastating. From the beginning, Katie treated my case with urgency and professionalism. At our emergency hearing, she was so prepared and so effective that the TPO was dismissed before court even officially got underway. That moment alone changed the entire direction of my case. Over the next two years, we navigated divorce, custody, child support, and a guardian ad litem. This was my first experience ever dealing with court, and I had no idea how the system worked. If there was ever a client who could have been taken advantage of, it would have been me but that is not who Katie is. She was transparent, communicative, and strategic every step of the way. She could have dragged the case out for billing purposes, especially in a county as busy as Cobb, but she did not. She focused on resolution and results. In court, Katie is a powerhouse. She is calm but commanding. She knows the law, she knows procedure, and she knows how to present evidence effectively. During our divorce hearing, she meticulously went through financial records and uncovered inconsistencies and income that the other side tried to hide. Her attention to detail mattered. She even ran the courtroom presentation seamlessly using her laptop and the projector something I didn’t even know was possible and it made a huge difference in how clearly our case was presented. The outcome: 50/50 custody and a fair resolution on support. We were even able to utilize a parenting time deviation strategy before it formally went into law in 2026. That level of forward thinking and preparation speaks volumes. Divorce and custody battles are emotional. Not everyone gets the outcome they hope for. But in my experience, Katie was honest about expectations, prepared me for reality, fought hard when it mattered, and delivered results. She was worth every penny. If you want an attorney who will advocate fiercely for you, stay composed under pressure, and truly bring the heat when it counts, I highly recommend Katie Leonard and the team at Leonard & O’Neil.

Relationship: Fellow lawyer in community

"Katie and I worked together as co-chairs of the Young Lawyers Division Family Law Section. Katie was a great co-chair and her involvement has been very beneficial to our committee. Katie is also an excellent advocate who works hard to get the best results for her clients. She is a great attorney who is able to work with her opposition to reach reasonable resolutions. But she is also more than capable of taking her cases before the court for a hearing if that becomes necessary."
