We know the adoption process can be stressful and frustrating. That’s why we take a proactive approach to all adoption cases and work to provide each family with the support and experience they deserve. We can help facilitate all forms of adoption, including stepparent adoptions, international adoptions, relative or grandparent adoptions, and domestic adoptions.


Domestic Violence Cases

If you have been charged with domestic violence or are facing allegations of family violence or abuse, it is important to seek the counsel of a respected attorney. A domestic violence conviction can impact every area of your life, so it is our goal to protect your rights and defend your future.


Real Estate

Our firm assists clients in commercial and personal real estate transactions, including purchasing, selling, leasing, and financing real property. This includes landlord/tenant disputes.


Wills & Estates

Without an estate plan in place, your family’s financial future may be vulnerable. It can be difficult to determine how your home, financial assets, and possessions should be divided after you pass. Taking the time to plan for this eventuality ensures that you or someone you designate has instructions on what happens to everything at once. Leonard A. Rosner and his team will work together with you to determine an estate plan and layout a will that carries out and outlines your final wishes.


Criminal Defense

If you are facing criminal charges, having an experienced attorney on your side is important for preserving your future. A criminal record can make finding future employment difficult, decrease your educational opportunities, and tarnish your personal and professional reputation. Leonard A. Rosner and his team will work to mitigate the consequences and give you the advice and protection you need.


Property Division

In New York, assets are divided into two categories: marital property and separate property. Leonard A. Rosner has over 30 years of combined experience and will help you determine which assets are which. He will provide you with a realistic outlook on how your property assets should be divided and will work with outside experts such as business evaluators, real estate appraisers, and accountants to assist in determining values. His goal is to provide you with an appropriate and equitable resolution by putting his years of experience to work for you.


Landlord & Tenant Matters

If you’re a landlord dealing with a tenant’s failure to pay rent and damages, we can help. Leonard A. Rosner also represents tenants who have been evicted or harassed by their landlord and are presented with uninhabitable conditions. Having legal counsel on your side is essential to properly resolving these matters.


Business & Commercial Matters

We provide various business law services, including preparation and drafting of all agreements, sale-purchase contracts for businesses (including equity positions), obtaining financing or funding to grow your enterprise. We prepare documents that perfectly fit you and all types of entities in need.
