A Different Kind of Family Law Firm

Built on trust, driven by expertise, and grounded in humanity, Jennifer and Nick created K+S to guide families forward with clarity, compassion, and strength.

Jennifer and Nick began working together in 2022 and quickly discovered a shared passion for helping families navigate some of life’s most challenging moments. What started as a professional collaboration soon grew into a genuine friendship, built on trust, empathy, and a shared vision for what family law could be. Over the years, countless conversations about their careers naturally expanded into conversations about the future of family law itself—and how it could better serve real people with real lives.

Together, Jennifer and Nick envisioned a firm that combines fierce, skilled advocacy with compassion and humanity. They believe clients deserve more than legal expertise; they deserve to feel heard, respected, and supported—no matter their background or circumstances. Recognizing that traditional family law practices often fall short of reflecting the realities clients face, they set out to create something different. K+S Family Law Group was founded on the belief that effective legal representation and kindness are not mutually exclusive. With a focus on understanding each client’s unique story, Jennifer and Nick strive to bring the law closer to lived experience—helping clients move forward with confidence, dignity, and hope. This firm was built to leave outdated approaches behind and to create a brighter, more compassionate future for the families it serves.

Nick Sung

Founding Partner

Nick Sung is passionate about helping families navigate the complex issues that they are experiencing in and out of court. Nick takes a wholistic approach when practicing family law and understands that that the legal issues that his clients go through have very real impacts on his clients’ lives. This approach helps Nick get great results in and out of the court room.

Nick is based out of our Douglas County office located in Castle Rock, but has extensive experience in courts all throughout Colorado from as high north as Jackson County to as far south as Pueblo county, and everywhere in between. Nick goes where his clients need him.

No case is too complicated for Nick to tackle. He is known for taking cases that are considered by many to be niche areas of family law – such as international abduction, third party allocation of parental rights, stepparent adoption and termination, etc. Nick is also highly experienced in taking cases involving high assets, reserved stock units, and property located outside of Colorado. One of Nick’s happiest moments was when he was able to reunite a child with his Father that had been abducted from the United States to Mexico. In order to achieve this result, Nick had to tackle the issue with courts in Colorado and Mexico, as well as work with an international agency called the Hague.

Nick is a Colorado and Douglas County native and was born and raised in Parker, Colorado. In fact, his parents moved to Parker when Main Street was still a dirt road. Nick graduated from Chaparral High School and went on to attend both Colorado State University and University of Colorado at Boulder in which he a received a bachelor’s degree in political science and a certificate in lesbian, gay, bisexual, and transgender studies. From there, Nick attended law school at Roger Williams University located in Bristol, Rhode Island. While in law school, Nick helped victims of domestic violence obtain protection orders against their abusers. Nick serves on the board of trustees for the Colorado Bar Foundation – which has the purpose of promoting the advancement of jurisprudence and the administration of justice throughout Colorado.

When Nick isn’t working, you can find him in the mountains, volunteering, and or trying new recipes with friends.
