Chelsey A. Christiansen focuses her legal practice on litigation, family and juvenile law, child custody, divorce, child support, and child advocacy. Ms. Christiansen has experience representing clients in family law matters at the mediation, arbitration, trial and appellate level. She also has experience providing litigation support to commercial clients, including drafting pleadings and representing the interests of commercial clients in small claims court.

Chelsey appeared before the Pennsylvania Supreme Court on April of 2021, and after three months, received the decision she and her client had advocated for throughout the nearly two-year appellate process. Representing "father", the appellee, she was able to obtain a consistent result – the vacating of a decree terminating father’s parental rights.

Ms. Christiansen appreciates that the nature of litigation, particularly within the context of the family unit, can be overwhelming. This is why she approaches all clients with compassion and empathy, motivated to achieve a satisfactory resolution in an expeditious and cost-effective manner.

Prior to joining High Swartz in 2019, Chelsey completed a judicial clerkship for the Honorable David R. Workman of the Court of Common Pleas of Lancaster County, Pennsylvania. Ms. Christiansen also has experience working for a local public interest organization, as well as a local public defender’s office.

Ms. Christiansen’s dedication to family and child welfare is longstanding and has been fortified by her educational experiences. A graduate of the Thomas R. Kline School of Law at Drexel University, Ms. Christiansen was honored with the Eve Biskind Klothen Law Student Pro Bono Distinction award. During her time at Penn State, Ms. Christiansen co-founded Boulevard, a community service organization committed to donating time and funds to THON.

Some of Chelsey’s noteworthy skills and accomplishments include:

  • Navigating juvenile clients and their families through the intake and adjudication processes
  • Successfully litigating a child support action and obtaining retroactive child support after proving opposing party shielded income
  • Negotiating comprehensive divorce settlements including settlement of all economic and alimony claims
  • Representing parents throughout all levels of the custody litigation process and negotiating favorable custody arrangements on behalf of clients

When not practicing law, Ms. Christiansen enjoys traveling and exploring the local community. A Montgomery County native, many of her weekends are spent rooting for the home teams, particularly the Nittany Lions.

Highly recommended, 5/5 stars!

I contacted High Swartz to help me navigate the custody issues I was facing with my ex, and I have been so pleased with the services I received. Chelsey Christiansen has been extremely helpful in helping me determine what was best for my child and myself while also remaining realistic. She was determined to have everything settled amicably, and thanks to that attitude my ex and I came to an agreement without having to take things to court. I’m very happy that I had Chelsey in my corner to advocate for what I wanted and what my child needed.

My mother and I worked together with Chelsey Christiansen and Mary Cushing Doherty for her divorce. Both were a pleasure to work with during this stressful time. Having to settle legal matters during lockdown was challenging but we did not feel any gaps in communication. We received fair advice and given realistic expectations.

Chelsey did an excellent job in explaining the steps involved, guiding me through the process and crafting a comprehensive PSA. The encouragement she provided was greatly appreciated. Her advice and counsel is invaluable. I would recommend that anyone entrust their future legal negotiations to her expertise.
