I am licensed in Montana and Arizona.  As a Montana native and received my law degree from the University of Montana School of Law in 2008.  Since completing my clerkship with the Montana Supreme Court in August 2009, I have been involved in family law practice, estates and trusts, and general civil practice.  

I practice in the areas of family law, including Collaborative, mediation, and uncontested, estates and trusts, employment, personal injury, government law, and business.

I believe that family law is about knowing what your options are.  It is important to know that there are different methods for going through these legal processes, and not all of them have to entail a fight.

It is my passion and purpose as a family law attorney to educate my clients about the steps in the process and their options along the way.  I am trained in mediation and collaborative practice and I tailor my approach to meet each client's specific needs.

I believe that using the right approach to address your family's legal issues will minimize emotional and financial costs for all involved.  I am a member of the International Academy of Collaborative Professionals, Montana Collaborative Professionals, Civil Collaborative Professionals, and the Helena Mediation and Collaborative Law Center.

When I am not advising clients, you can find me enjoying all of the outdoor activities Montana has to offer with my husband and pembroke corgi dog.

Wonderful Experience
This was my first experience dealing with the legal system and having a lawyer. I was going through a divorce and setting up a parenting plan. Hilary was so kind, knowledgeable, and helpful along the way. She was there for me every step of the way. I could confide in her. She explained everything to me. After the retainer was paid, I couldn’t pay her all the money at once. She and I worked out a payment plan until I was paid up. She kept in touch with me regarding the progress and next steps, as well as answered all my questions. I would recommend her to anyone. In fact I already have and a friend of mine is utilizing her services.

Professional and Compassionate
I was blindsided by a request for a divorce from my husband. I had quit my job many years prior to raise our kids and support my husband as he furthered his career. After spending countless hours speaking to attorneys on the phone, across the state of Montana, I finally found Ms. Oitzinger. She was compassionate, knowledgable and professional. She agreed to work with my husband and I as a mediator, and I know that it went well because of how she handled the dynamics of the process. I am so grateful to her.
