Rossberg Law Office, L.L.C.

Sunday Z. Rossberg opened Rossberg Law Office, L.L.C. in 2000, and since that time, she has maintained an active family law practice. Sunday feels privileged to practice an area of law that shapes a person’s future like none other. “I am compassionate and dedicated about my work. I understand that I am not just working on a case, but I am affecting a person’s life. When I create a parenting plan for a family, I realize that I am creating the framework for that family for years to come. That parenting plan will affect the type of life and lifestyle that a child can enjoy.”

Sunday believes that each person who comes in the door deserves individual attention. “When people walk into my office, they are often at their worst, and are facing some of the worst times in their lives. Usually, they are either in a custody battle or at the beginning of a divorce. I try to get into their skin and see matters from their eyes. They often believe life as they know it is coming to an end, and they need someone to help sort through the rubble.”

Even though Sunday’s primary emphasis is family law, she has a whole spectrum of legal experience where she has practiced in the following areas of law: wrongful termination from employment; criminal defense; private business representation; real estate fraud litigation; personal injury litigation; wrongful death claims; youth in need of care proceedings; and inmate civil rights.

At the infancy of her career, Sunday was instrumental in changing Montana law and the treatment of mentally ill inmates in Walker v. State, 2003 MT 134, 316 Mont. 103, 68 P.3d 872 which was a 6 to 1 decision by the Montana Supreme Court, and the first case in Montana to address the Human Dignity Clause in Montana’s State Constitution.

Sunday has proven to be a tireless advocate for her clients and has a demonstrated history of success. Sunday has practiced law for over fourteen years, and for over ten years, the bulk of Sunday’s practice has been centered around representing families in the midst of their divorces and parenting plan disputes. Sunday is knowledgeable and experienced with:

complex debt and asset distributions
child custody and visitation
customized parenting plans
spousal maintenance (alimony)
farm and ranch divorces
child support
military divorces
grandparents’ rights
parental alienation
domestic violence
restraining orders
