Helping Parents Establish or Challenge Paternity in New York

Establishing paternity is an important legal step that can affect child support, child custody, parenting time, inheritance rights, and many other legal issues.

With more than 40 years of family law experience, Attorney Lynn Poster-Zimmerman helps parents navigate the legal process while protecting their rights and the best interests of their children.

Benefits of Establishing Paternity

Establishing legal paternity provides important benefits for both the child and the parents.

For the child, paternity may provide:

  • Financial support from both parents
  • Access to health insurance and other benefits
  • Eligibility for Social Security, veterans, or inheritance benefits
  • Access to the father's family medical history
  • The opportunity to develop a meaningful relationship with both parents

For parents, establishing paternity creates legal clarity regarding parental rights, responsibilities, and decision-making for the child.

Establishing Paternity

In order to establish paternity, a father can voluntarily acknowledge his parenthood through acknowledgment documents. If the father does not do this, the mother may pursue paternity establishment through the court system. The primary way to show non-paternity in a conclusive way is through DNA testing. In cases like this, the alleged father as well as the mother and child must submit to genetic testing. If the test results determine that the man is the biological father of the child, then paternity will be recognized as a legal factor.

Such testing can determine paternity with 99 percent accuracy. However, there are other legal means to prove or disprove paternity, such as through equitable estoppel. This is a legal concept whereby the father may be deemed to be the legal father if he has established a relationship with the child, who believes him to be his father. This is a highly technical legal argument requiring the expertise of an experienced family law attorney.

Why Establishing Paternity Matters

Once paternity is legally established, either parent may seek court orders regarding:

  • Child support
  • Child custody
  • Parenting time (visitation)
  • Medical insurance and healthcare expenses
  • Decision-making authority
  • Modification of existing family court orders

Whether you are seeking financial support, pursuing fathers' rights, or protecting your relationship with your child, establishing paternity is often the first step.
