    Andrew Proto is the lawyer you want
    For over 2 years I was involved in an extremely emotional, high-conflict family dispute with my parents, one of whom has serious mental health problems. Andrew Proto was the best choice for me after meeting him for his knowledgeable, detail-oriented and sharp legal expertise in family law and was instrumental in resolving my family situation without the added stress and expense of a trial. Mr. Proto navigated my case strategically, providing me with sound advice and answered all my questions patiently, especially all my "What ifs" (and I had plenty of them). Another notable quality I appreciated was Mr. Proto's ability to be sympathetic, available and reassuring to me while I was dealing with such a difficult, sad and stressful time. The staff was also very understanding and proactive when the circumstances required it. Andrew Proto is the lawyer YOU want on your side.

    Andrew Proto is OUTSTANDING
    Andrew Proto is OUTSTANDING. Customer service is amazing. The office staff is very nice and helpful. Mr. Andrew is very knowledgeable. He was always available or made time for my questions and concerns. Very good responding in a timely manner as well. I received, in my opinion, the most nonsense CPS case in the world. Mr. Andrew protected my employment and my children. I’m glad to say as long as I have my children and career that’s what matters. I will definitely hire Mr. Andrew for another situation if I come across one. And I must add in, Mr. Andrew and his team are not after your money; they really are here to help. Thank you, Mr. Andrew.

    Do Not Navigate the Courts on Your Own
    From my initial call to the final negotiation, David and his team were superb! He gathered a few details of my case and took control of everything from there. Final result was a smooth, successful negotiation down to a very minor, manageable traffic offense. Do not navigate the courts on your own! Let David and his team take over the burden for you. You will not be disappointed!

    Andrew Proto and his team are excellent
    Andrew Proto and his team are excellent: effective, efficient, easy to work with. I and a couple of my friends asked Andrew to help with tickets, and every time he was able to go to court and interact with the court employees instead of me (a huge time saver!), represent my side, and ensure that the right agreement is reached. Thank you, Andrew!

When an urgent issue came up, he answered my call after hours and immediately stepped in to contain the situation, which meant more to me than I can express. He was calm, reassuring, and took the time to explain everything in a way I could understand. Throughout the entire process, I truly felt supported and knew he had my best interests at heart.

    He got my case completely dropped
    Andrew, I can’t thank you enough! Mr. Proto is by far the best attorney I have ever met. He handled my DWI case very well as he displayed professionalism and efficiency. He presented me with options and offered solutions and advice. Most importantly, however, at the end he got my case completely dropped into a traffic infraction in the court, which is truly brilliant considering my situation. I highly recommend Mr. Proto as he is an amazing attorney. He works with you, he also responded to all my emails immediately and kept updating me on my case. I’m referring him to all my friends and family. Thank you so much for everything!

    Case Dismissed Court Dismisses Alleged Violation of Conditional Discharge in Westchester County

    After a full hearing, a local Westchester County court dismissed a violation of conditional discharge that had been brought by the District Attorney’s Office. The client had previously pled to a Driving While Ability Impaired (DWAI) charge and was later rearrested for Driving While Intoxicated (DWI) in another state.

    Attorney review showed that the out-of-state case was ultimately resolved without a criminal conviction. Based on that outcome, the judge agreed that the client had not violated the original conditional discharge, resulting in the case being dismissed in full.

    Quick Legal Insights
    • What if the other party opposes the modification?
      If the other party opposes the modification, the matter may go to court where a judge will review evidence from both sides. The court will make a decision based on the best interests of any involved children and the current circumstances of both parties.
    • Can we modify an order without going to court?
      In some cases, parties can agree to modify an order without a court hearing by reaching a mutual agreement. However, to ensure the modifications are legally binding, it's recommended to get court approval, even if both parties agree on the changes.
    • Is court approval necessary for modifications?
      Yes, court approval is necessary to legally change an existing family law order. It's important to follow legal procedures to ensure any modifications are enforceable and recognized by the court.
    • How long does the modification process take?
      The duration of the modification process can vary based on the complexity of the case and the court's schedule. It can take a few weeks to several months to finalize, so it's best to start the process as soon as a change in circumstances is identified.
