Jennifer Lancaster is the founder of Cornerstone Law Firm, where she is dedicated to helping Arkansas families rebuild, protect, and prosper. Rooted in her Christian faith and driven by a belief in strong families and strong communities, Jennifer focuses her practice on bankruptcy, estate planning, business formation, and faith-based family empowerment.

After graduating from law school, Jennifer opened her own law practice immediately, representing Arkansans from all walks of life in complex, high-stakes matters. Following several years of private-practice experience, she was selected to serve as a Staff Attorney at the Arkansas Supreme Court under Conservative Justice Barbara Webb, where she assisted in the review and analysis of cases before the state’s highest court.

In 2020, Jennifer was honored to serve as part of President Donald J. Trump’s legal team during the post-election litigation. Her work included representing President Trump in the Wisconsin presidential recount, one of the nation’s most scrutinized election-law battles.

Jennifer has also represented high-profile clients in sensitive and nationally watched matters, including serving as counsel for Lunden Roberts in the child support and custody case involving Hunter Biden. Her work in that case helped ensure accountability and protection for her client and child.
Beyond her courtroom work, Jennifer is known for fighting for the voiceless—including animals. She has been actively involved in animal-welfare efforts across Arkansas, advocating for improved treatment, transparency, and enforcement.

At Cornerstone Law Firm, Jennifer combines her litigation experience, constitutional insight, and compassionate advocacy to help families overcome financial hardship, regain stability through bankruptcy when needed, and then secure their future through thoughtful estate planning. Her mission is simple: Give families a fresh start, protect what matters most, and empower them to build a legacy for future generations.

Clients working with Jennifer don’t just receive legal representation—they receive counsel grounded in faith, integrity, and resilience, from an attorney who has stood on some of the biggest legal stages in the country while continuing to serve the everyday Arkansans who need her most.

In addition to her legal practice, Jennifer is the founder of Arkansas 1st, an initiative focused on civic leadership and informed public engagement across the state. She is also the founder and board member of the Lancaster Animal Project, where she advocates for stronger animal welfare protections and responsible policy reform in Arkansas. Jennifer holds a Certificate of Completion in Accounting from Harvard Business School, strengthening her ability to advise business owners with both legal and financial insight. Her work reflects a commitment not only to excellence in the law, but to leadership, service, and building institutions that create lasting impact.

Jennifer is not only dedicated to her clients, but to living life with purpose and discipline. Outside the courtroom, she homeschools her two daughters, intentionally investing in their education, character, and faith. She is a multi-time Ironman 70.3 triathlon finisher who embraces the challenge of endurance training as a reflection of her belief that resilience is built, not given. When she’s not training or teaching, she enjoys scuba diving, snow skiing, travel, and outdoor adventures that push her outside her comfort zone. Whether in business, athletics, or motherhood, Jennifer approaches every challenge with focus, faith, and a commitment to excellence.
