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. Can my husband file for temporary full custody after his daughter self-harmed in the mother's care?
- A: Yes, your husband can take legal steps to seek temporary full custody if there’s a serious concern about his daughter’s safety, especially following something like a suicidal attempt or serious self-harm in the mother’s care. In a situation like this, he should talk to his attorney about filing an emergency motion to modify custody, requesting temporary sole physical custody. Courts will often grant emergency relief only when there’s a credible threat to the child’s physical or emotional safety, so having documentation, such as medical records, mental health evaluations, police reports, or statements from professionals, is crucial.
Another option might be filing an Order for Protection ... Read More
- Q. Is an unwed mother in any way obligated to put the biological father on the birth certificate.
- A: In Minnesota, an unwed mother is not legally obligated to put the biological father’s name on the birth certificate at the time of the child’s birth.

The Minnesota Department of Health explicitly states that in the case of unmarried parents, the father’s name is not automatically added unless one of those two steps is taken. ... Read More
- Q. Can I request judicial help for spouse-neglected mortgage payments during a divorce?
- A: In your situation, make sure you talk to your lawyer right away about requesting a temporary relief hearing (sometimes called a motion for temporary relief). These hearings are meant to address urgent issues like missed mortgage payments or custody if you have kids while the divorce is still pending. I call it a band-aid or setting the rules of the divorce.
You can ask the judge for temporary financial help to make sure the mortgage is paid, including asking the court to order your spouse to either make their share of the payments or reimburse you if you cover more than your half. There are a lot of options on what to do in terms of asking the court for help here.
Be aware that it typically ... Read More
