Representation In New York Family Law
All family law cases have critical issues at stake; after all, these matters will shape your future and the future of your children. Much of your financial and emotional well-being will be controlled by the outcome of your case, so you want a lawyer with the experience and skill necessary to protect your interests while working to achieve your goals.
I have the legal experience necessary to effectively represent clients in complex matrimonial law, child custody and support cases, as well as other high-conflict family law matters. I also have experience with high-asset divorce cases, which may include dividing a business, finding hidden assets, and valuing sophisticated financial assets.
Real Estate Transaction And Litigation Services
Whether a residential or commercial matter, real estate transactions need to be handled with the utmost care and due diligence. Additionally, when real estate disputes become real estate litigation, you want an attorney with extensive experience and a record of success in the courtroom.
I represent homeowners, businesses and contractors in New York real estate transactions and litigation. I understand that your home or your business may be at stake. From title issues to mechanic’s liens and construction defects, you can be certain that I will handle your matter with care and seek effective solutions.
Resolving Disputes And Protecting Your Rights In Civil Litigation
Civil litigation encompasses a broad spectrum of legal issues, and I handle many of them, including employment and labor law, landlord-tenant law, contract disputes, contractor and subcontractor disputes, personal insurance adjuster contracts, Title IX cases, employment discrimination and wage-and-hour disputes.
While I will work to resolve your case through negotiation, mediation or arbitration, I will also be prepared to take it to trial when that is in your best interest as I have substantial experience with complex litigation matters. I am well-known in the local legal community for my professionalism and preparation in the courtroom.

Resolving Sophisticated Problems In Estate Planning And Estate Litigation
Whether you have an estate plan or are wondering if you need one, you will benefit from the knowledge and experience I have gained over many years of practicing estate planning. You may be an individual with modest assets or a business owner with complex assets; in either situation, you need an experienced attorney to protect your future, your family and your legacy.
I can assist you with drafting or updating an estate plan, or I can represent you in estate litigation if disputes arise after the death of a loved one. In both cases, I will be sensitive to your needs and the needs of your family.
