Jessica J. Sauer, Esq.

Attorney at Law

Passionate about helping families navigate life’s inevitable realities with confidence and grace, Jessica has been practicing law for over fifteen years and is licensed to serve clients in New Jersey and Pennsylvania.

Jessica J. Sauer, Esq. focuses her practice on:

  • Estate Planning (creating wills, trusts, and powers of attorney)
  • Estate Administration (probating wills and administering estates, preparing inheritance tax returns) &
  • Court Matters related to assets and planning (estate litigation, guardianships, conservatorships, and adoptions) 

Jessica is a co-chair of the Estate Planning and Probate Committee of the Mercer County Bar Association. She has provided continuing legal education to other attorneys through the New Jersey State Bar Association and has spoken about estate planning and charitable giving to various community groups and organizations.

She focuses her legal practice on estate planning – helping families prepare for the future by doing what they can to help minimize conflict, unnecessary expenses, and aggravation down the road. She is passionate about preparing legal structures (and putting organizational systems in place) so that clients can achieve their goals. In a logical progression from this work, she is also willing to assist families with estate administration needs after a loved one passes away.

While most of her practice is transactional, Jessica has the advantage of being an experienced litigator. As such, she is willing to engage in a limited number of estate litigation matters (such as will contests and actions to interpret and improve the administration of trusts) and guardianship proceedings (court cases arising from situations where someone has failed to execute effective powers of attorney and needs someone to be able to help take action on their behalf). Jessica also assists clients with setting up trusts to receive the proceeds from personal injury matters and other legal settlements (including first and third party special needs trusts).

Jessica resided in Edgewater, New Jersey before relocating to the greater Princeton area to work with an established boutique estate planning and estate administration practice. She established The Sauer Law Firm LLC in 2020, using technology where appropriate to make the estate planning process efficient and convenient.

Jessica was awarded the Doris Dealaman Youth Advocate of the Year Award in 2024 through the Somerset County Office of Youth Services for her work in child welfare. A former law guardian, Jessica has volunteered her time to serve as the Director of the Child Advocacy Association of New Jersey (CAANJ), to help launch the CarePortal Network (a platform to help churches become aware of and respond to child welfare needs in their community), and to assist with respite nights and fund raising events for Miriam’s Heart (a local nonprofit dedicated to supporting children who have been adopted or at risk of abuse & neglect and their families). These experiences have given her experience with complex family and organizational issues and dynamics. 

A graduate of the Pepperdine University Charles Widger School of Law (the campus overlooks the Pacific Ocean in Malibu, California), she served as an editor of the Pepperdine Dispute Resolution Law Journal and earned a CALI Award for Excellence in Arbitration Practice (as well as a Certificate in Alternative Dispute Resolution). She externed for the Honorable Lawrence J. Mira of the Los Angeles County Superior Court. Jessica is a Magna Cum Laude graduate of Grove City College. She has also deepened her familiarity with sophisticated tax planning strategies for high net worth families through coursework towards an L.L.M. in Taxation at Villanova University,
