About us


Rumbold & Seidelman was founded in 1996 by Nina Rumbold and Denise Seidelman with the understanding that our law practice was, first and foremost, about helping to form families utilizing the highest ethical and legal standards. We are admitted to practice in New York and New Jersey and we practice in many courts throughout both states. Rumbold & Seidelman has represented many hundreds of clients to adopt or place their children with integrity and love. We also concentrate our practice in the evolving field of reproductive law and have counseled intended parents, egg, sperm, embryo donors and gestational carriers in collaborative reproduction arrangements.

Since its inception, Rumbold & Seidelman has been dedicated to the core belief that our practice should be non-adversarial and collaborative and should benefit all members of the adoption triad or participants in collaborative reproduction.  In addition to our work on behalf of our clients, Rumbold & Seidelman took a leadership role in the effort to reform of New York State’s antiquated parentage law as it relates to third-party reproduction (children conceived through sperm, egg, or embryo donation or surrogacy). We had a principal role in drafting and advocating to gain passage of the Child-Parent Security Act (CPSA) which, after a 10-year effort, took effect in New York in February of 2021.  We have also been directly involved in a number of groundbreaking New York cases which have expanded the ability of New York intended parents to secure their legal relationship with their children.

While Nina is now “of counsel” to Rumbold & Seidelman, and not routinely representing clients, the imprint she left after twenty-four years of active involvement in our law firm is evident in everything we do.
