Katherine E. Ingrassia is a Partner and one of the principal trust and estate attorneys in northern New Jersey. She has spent more than 20 years practicing estate and tax planning, trust and estate administration, elder law and care planning, guardianships as well as special needs and disability law. Her practice includes wills, trusts, gift and estate tax, estate administration and probate, and her clients include high net worth individuals, individual and corporate trustees and executors and estate and trust beneficiaries. 

Ms. Ingrassia specializes in counseling individuals and families on estate planning and wealth transfer matters with a focus on tax savings and asset protection. She has extensive experience in the drafting of estate planning documents, such as wills, revocable living trusts, insurance trusts, durable powers of attorney, and advance medical directives. She works with clients whose needs range from simple to highly sophisticated. Her estate plans incorporate estate taxation strategies, asset preservation for future generations and succession planning for closely held businesses.    

Her experience includes representing executors, administrators and heirs, assisting with the administration of estates, handling the distributions of assets, and preparing disclaimers and estate accountings. She also prepares estate tax returns, including Federal Estate Tax Returns (Form 706), New Jersey Estate Tax Returns and New Jersey Inheritance Tax Returns.

Ms. Ingrassia has also represented individuals seeking to be appointed as guardian(s) for alleged incapacitated adults before the Superior Court of New Jersey. Such clients have included parents of adult children with disabilities such as autism and spouses or children of adults with dementia. She has significant experience in Probate Court proceedings and fiduciary litigation matters. Recently, Ms. Ingrassia has represented fiduciaries in proceedings involving admitting a copy of a Will to probate and the issue of the “Omitted Spouse” statute. Among her clients are also beneficiaries seeking accountings from executors and distributions from the estate.

Further, Ms. Ingrassia counsels clients in asset protection plans and Medicaid eligibility for the elderly and the disabled. Such planning involves the preparation of Qualified Income Trusts and Special Needs Trusts. She works closely with individuals and families to ensure that the correct plan is implemented and properly executed.
