We Solve Problems.
Jason Kohlmeyer has spent the past 20+ years guiding families through some of life’s most difficult moments—divorce, custody battles, and high-conflict parenting disputes. Since moving to Southern Minnesota in 2000 to trade Fargo’s frozen tundra for warmer ground, Jason has become a trusted advocate for clients facing complex and emotionally charged family law issues.
A veteran of the U.S. Army Reserve, Jason served in both military intelligence and as an infantryman. That discipline, focus, and strategic mindset now serve him well in the courtroom.
Jason focuses exclusively on family law, with a niche in high-conflict divorce and custody cases—especially those involving significant financial disputes or contested parenting time. Over the course of his career, he’s handled nearly 1,500 family law matters, including divorces involving business valuations, hidden assets, mental health concerns, and difficult co-parenting dynamics.
Don't take Jason's word for it, he's been named a SuperLawyer from 2014-2025 (limited to 5% of MN lawyers) and named a Best Lawyer by US News & World Report from 2019-2025
Whether negotiating a peaceful resolution or fighting aggressively in court, Jason brings clarity, candor, and results-driven advocacy to every case.

- Q. Am I giving up my house equity if I sign the separation agreement?
- A: I think you might be a bit loose on your terminology. Is it just a piece of paper she wrote up? Is it a full blown marital termination agreement? That is a huge distinction.
I think it's pretty important you find the time to talk to an experienced family law attorney and see what they have to say. You don't want to make a mistake and not be able to come back from it.
