Jessica J. Sauer, Esq. has been practicing law for over fourteen years and 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 (guardianships, conservatorships, and adoptions) 

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

Jessica began her career as a law guardian, advocating and litigating on behalf of children and young adults involved with child protective services in Bergen County and Hudson County. These experiences have provided her with knowledge of and sensitivity to the unique challenges faced by families struggling to address drug addiction, mental health issues, special needs, and contentious custody situations – a background that strengthens and informs her work in trusts and estates. She has remained involved in child welfare by serving as the Director of the Child Advocacy Association of New Jersey. She also volunteers as the Director of Advocacy for Miriam’s Heart (a grassroots non-profit that supports adopted and foster children and their families). Jessica has been instrumental in the launch of the CarePortal network in New Jersey – a platform for empowering communities to meet the needs of children.  

Her primary practice focus is 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 helping give her clients peace of mind by creating legal structures and putting organizational systems in place to help them achieve their goals. 

A Bergen County native, Jessica attended law school at Pepperdine University located on the coast of the Pacific Ocean in Malibu, California. She served as an editor of the Pepperdine Dispute Resolution Law Journal, volunteered at the Union Rescue Mission Family Law Clinic, earned a CALI Award for Excellence in Arbitration Practice, and externed for the Honorable Lawrence J. Mira of Los Angeles County Superior Court. Jessica is a Magna Cum Laude graduate of Grove City College, and is currently pursuing an LL.M. in Taxation at Villanova University to deepen her familiarity with sophisticated strategies designed for the needs of high net worth families. 

Jessica resided in Edgewater, New Jersey before relocating to the greater Princeton area in 2015 to work alongside experienced estate planning and administration attorneys at a boutique estate planning and estate administration practice. She opened The Sauer Law Firm LLC at the end of 2020 – using technology and virtual meetings where appropriate to make the estate planning process efficient and convenient.
