Third-Party Custody

While the law fundamentally protects the rights of biological and legal parents, there are circumstances where a parent is unable or unfit to provide care. In these cases, third-party custody, or custody awarded to a non-parent, may be necessary to ensure a child’s safety and stability.

In Maryland, the legal bar for third-party custody is high. At Turnbull, Nicholson & Sanders, P.A. (TNS Family Law), we represent both non-parents seeking to protect a child and parents asserting their parental rights against third-party filings. We provide a disciplined, evidence-based strategy to navigate these high-stakes disputes.

Understanding the Legal Threshold for Third-Party Custody in Maryland


Maryland courts begin with the strong legal presumption that it is in a child’s best interest to be raised by their parents. To overcome this presumption, a third-party must meet a rigorous legal standard. You must prove one of two things:

  • Parental Unfitness: Evidence that the parent is unable to provide proper care due to neglect, abuse, or other significant issues.
  • Exceptional Circumstances: Situations where the child’s bond with the third-party is so significant, or the parent’s absence so prolonged, that it would be detrimental to the child to remain with or return to the parent.

Our attorneys are well-versed in third-party custody law and take a disciplined, evidence-based approach to these cases.

Maryland does not allow just anyone to seek third-party custody of a child. Some of the most common people who will petition for third-party custody include:

  • Grandparents and extended family members
  • Stepparents who have served as a primary caregiver but have not legally adopted the child
  • De Facto Parents: A specific legal status in Maryland for non-parents who have lived with the child and formed a parent-like bond with the biological parent’s consent
  • Long-term caregivers or family friends with a “substantial relationship” to the child

Common Scenarios for Third-Party Custody Cases


Third-party custody cases often arise out of crisis or long-standing informal arrangements. We assist clients with:

  • Emergency Petitions: When a child is in immediate danger due to parental substance abuse or domestic violence
  • Established Caregiving: When a child has lived with a relative for a significant period and the parent suddenly attempts to disrupt that stability
  • Intervention: When a third-party needs to join an existing custody case between two parents to protect the child’s interests

Throughout the third-party custody process, our focus remains on clarity, preparation, and presenting a persuasive case grounded in the child’s needs.

Meeting the Legal Standards for Third-Party Custody


Our attorneys focus on gathering meticulous evidence, including school records, medical documentation, and expert testimony, to build a persuasive case grounded in the child’s actual lived experience.

At the same time, we recognize that these cases often involve delicate family dynamics. We approach every matter with the discretion and sensitivity required to manage strained relationships, always keeping the child’s long-term well-being as our goal.
