Probate Lawyers Serving New York & New Jersey

Lawyers for Probate Court and Will Contests

In New York and New Jersey, the probate process – establishing the validity of a will and obtaining the appointment of the executor(s) – should be straightforward, simple, and relatively inexpensive. Nevertheless, sometimes problems arise. The legal proficiency and nearly four decades of experience of Kantrowitz, Goldhamer, Graifman, Perlmutter & Carballo, P.C. can help you avoid or resolve litigation.

The best way to avoid probate issues is through solid estate planning. Without effective planning, heightened emotions following the death of a loved one can serve to produce issues and disputes among family members. When even the best efforts cannot completely eliminate outrageous allegations of undue influence, incompetency or fraud, our KGG probate and estate lawyers protect your rights.

Do I Need a Lawyer to Administer a Will in Probate Court?

The KGG estate law team has a proven record of positive results. For decades, we have been helping our clients secure the futures they want for their families.

At Kantrowitz, Goldhamer, Graifman, Perlmutter & Carballo, P.C., we assist you and your family to prepare for and go through the probate process, beginning with estate planning that can withstand any challenge. In addition to probate cases, KGG can assist you in any aspect of estate planning, including: durable powers of attorney, advanced health care directives, Medicaid planning, trusts, life insurance, business succession planning and guardianships.

When an estate or trust is in administration, we coordinate with executors and trustees to ensure that you, the beneficiary, receive the justice you are due. Our attorneys are experienced in diplomatically handling investigations, negotiations, and litigation with equal resolve.

Need to Contest a Will in Probate Court?

If you have been deprived of your rightful inheritance because a loved one has fallen prey to manipulation, we can help put things right. We can contest a will or trust if you believe the document was drafted or executed incorrectly, or if it was the result of undue influence or duress. Spouses are entitled to a specific share of an estate under the law. If you are a spouse who has been disinherited by a will or trust, we will protect your rights in court to ensure you receive everything to which you are entitled.

If it becomes necessary to present your matter in a courtroom, we will not hesitate to be forceful in the defense of your rights. No matter where your probate, estate or trust administration takes you, we can be right there alongside you with solid support and quality legal guidance that protects your rights.

 Trustindex verifies that the original source of the review is Google. KGG Law, and Barry Kantrowitz in particular, set the bar high for what a thorough, practical, strategic, compassionate and smart lawyer can be. Everything about Barry's advice and representation was exemplary and the stress mitigation that resulted was invaluable. On top of that, the ultimate result Barry achieved was beyond what was reasonable to expect and we are forever grateful. Often, people say that you hire a lawyer to prevent a problem. Sometimes, unfortunately, you need an attorney to solve a problem and I could not recommend Barry and his firm any more highly in that regard.

From the very beginning, the team was professional, knowledgeable, and always willing to answer our questions. They kept us informed throughout the entire process and made what could have been a very stressful situation much easier to handle. We truly appreciated their dedication, honesty, and hard work. Thanks to their support, my dad felt confident every step of the way. We are very grateful for everything they did and would highly recommend this firm to anyone looking for reliable legal representation.

He was very responsive, thorough, and easy to work with from start to finish. He walked me through everything clearly and made what started as a very stressful situation for me into something completely manageable. I would not hesitate to recommend him and the firm!

 Trustindex verifies that the original source of the review is Google. Kate Carballo is a dedicated, passionate, and creative attorney whom I had the pleasure to lecture with at a state trial lawyer's conference. Kate's lecture demonstrated how she uses her innovative and "out-of-the-box thinking" to achieve outstanding results for her injured clients. That Kate is certified by the Supreme Court of New Jersey as a civil trial attorney is a testament to her skills, experience and commitment to excellence.

 Trustindex verifies that the original source of the review is Google. Was referred to KGG law by a friend and could not have asked for better legal representation. They walked me through every step of the process after my accident and began every call with “ how are you feeling” which was just one example of how much they care about their clients. They handled my case very efficiently, professionally and courteously. My attorney Kate Carballo was a rock star! So clearly experienced, she consistently made me feel at ease with the process. Highly recommend

 Trustindex verifies that the original source of the review is Google. We had a great experience with the team at KGG Law. While it was a traumatic time for our family, they made it very easy for us and explained all of our options. They even performed due diligence to make sure that after our settlement, there would be no further issues which I think is even more important than the settlement itself. Thank you!
