Our Estate and Probate Litigation Practice

We are experienced trial attorneys who handle all types of estate and probate controversies, including disputes involving:

  • Contested estate planning documents—We represent parties in disagreements over the validity of a will, trust or power of attorney, including allegations of lack of capacity (such as dementia), undue influence, fraud or duress.
  • Breach of fiduciary duty—We take claims involving allegations of improper acts by administrators, executors or personal representatives, including conflicts of interest, self-dealing, and accounting irregularities.
  • Beneficiary claims—We advocate for rightful beneficiaries who were excluded or denied an inheritance. This includes spouses seeking their elective share, as set forth in New York law.
  • Complex property division—We help resolve disputes over the distribution or allocation of jointly owned real estate, as well as the proceeds of a wrongful death lawsuit.
We represent out-of-state executors and administrators in estate litigation in New York.

There are Two Types of New York Estates

  1. The Decedent resided in NY at the time of death and their domicile is New York at the time of death; or
  2. There are assets located in NY, at the time of death, and an ancillary proceeding is needed. The Decedent may have died elsewhere.
