Create clarity and protection tailored to your unique relationship and family structure.

What Are Polyamorous and Non-Traditional Relationships?

Relationships today take many forms—and so should your legal options. From consensual non-monogamy to chosen families and non-married life partners, these relationship structures often fall outside the protections of traditional family law.

At Vacca Family Law Group, we believe your relationship deserves respect and legal recognition, even if the law hasn’t caught up yet.

Do You Need Legal Support for Your Non-Traditional Relationship or Separation?

If your relationship involves more than two people, doesn’t include marriage, or doesn’t fit the legal mold, you’re not alone—and you don’t have to navigate these complexities on your own.

Whether you’re planning for the future or preparing for a peaceful separation, legal support can help protect your rights and reduce confusion.

  • Polyamorous, open, or ethically non-monogamous partners
  • Cohabiting or LAT (Living Apart Together) partners
  • LGBTQ+ and chosen families

Why Legal Agreements Matter in Non-Traditional Relationships

Even though New York law does not currently provide a clear legal framework for polyamorous or non-traditional relationships, proactive legal planning can protect your interests, reduce uncertainty, and honor the intentions of everyone involved.

When multiple people share a home, expenses, or assets, it’s important to establish who owns what and how responsibilities are divided. Legal agreements provide transparency and prevent misunderstandings down the road.

If a relationship changes or ends, we help you navigate the transition with dignity and respect. Through collaboration, negotiation, or mediation, you can create customized, out-of-court solutions that work for everyone involved.

A cohabitation agreement can define the roles, responsibilities, and expectations of each partner—whether you live together as a couple, trio, or in another configuration. These agreements offer legal protection tailored to your unique family structure.

When children are part of a non-traditional household, parenting roles may not be legally recognized by default. We help you document and clarify each adult’s caregiving responsibilities to support the children’s well-being and minimize conflict.
