Grandparents' Rights: When They Can Legally Seek Custody or Visitation

The bond between grandparents and grandchildren is precious and irreplaceable. Yet when families fracture due to divorce, death, or conflict, grandparents often find themselves suddenly cut off from the grandchildren they love. The legal landscape surrounding grandparents' rights is complex and varies significantly from state to state .

In 2026, several states have introduced or passed significant legislation affecting grandparents' ability to seek visitation or custody. From Indiana's new standards for meaningful contact to South Carolina's expansion of rights to great-grandparents, the law is evolving. This comprehensive guide explains when grandparents can legally seek visitation or custody, what courts consider, and how to navigate the legal process.

The Landmark Case: Troxel v. Granville (2000)

The United States Supreme Court recognized a parent's liberty interest—perhaps one of the oldest—in its decision in Troxel v. Granville, a case which struck down a Washington statute granting visitation rights to any person when such visitation was in the best interest of the child. The Court held that the statute unconstitutionally interfered with the parents' rights to raise their children.
Fit Parent Presumption: A fit parent necessarily will act in the best interest of the child, and in such case, there would be no need for the state to interfere .
Fundamental Right: Parents have a fundamental right to make decisions regarding the care, custody, and control of their children .

This presumption remains the cornerstone of all grandparent visitation and custody cases today.

Texas Supreme Court: The Fit Parent Presumption in Modification Cases

In Re C.J.C. (Texas Supreme Court)
"When a nonparent requests conservatorship or possession of a child, the child's best interest is embedded with the presumption that it is the fit parent—not the court—who makes the determination whether to allow that request."

The court held that even though neither the nonparent standing statute nor the general modification statute includes the fit parent presumption, that presumption is embedded in the best interest analysis. The father was entitled to a presumption that he determined the child's best interest based on his fundamental right as a fit parent .

Illinois: Expanding the Harm Standard

SB 1642 amends 750 ILCS 5/602.9 to add a critical factor for courts to consider:

In determining whether to grant visitation, the court shall consider "any other fact that establishes that the loss of the relationship between the grandparent, great-grandparent, sibling, or step-parent and the child is likely to harm the child."

The bill also adds detailed conditions for when grandparents may petition:

Parent deceased or missing 90+ days Parent legally incompetent Parent incarcerated 90+ days Parents divorced/separated (non-objecting parent) Unmarried parents not living together

Rebuttable presumption: There is a rebuttable presumption that a fit parent's actions and decisions regarding visitation are not harmful to the child. The burden is on the grandparent to prove undue harm .

South Carolina: Great-Grandparents Included

South Carolina's H. 4647 amends Section 63-3-530 to explicitly include great-grandparents in visitation statutes .

Clear and Convincing Evidence Required

Courts may order great-grandparent visitation where:

  • Parents unreasonably deprived great-grandparent of visitation for over 90 days
  • Awarding visitation would not interfere with parent-child relationship
  • AND either: parents are unfit (clear and convincing evidence) OR compelling circumstances overcome the parental presumption

The court may award attorney's fees and costs to the prevailing party .

New York: What Constitutes Extraordinary Circumstances?

Morris v. Smith (NY Appellate Division, 2026)

The court reversed dismissal of a grandmother's custody petition, finding she did establish extraordinary circumstances:

  • Child resided exclusively with grandmother since age 2 (now 6)
  • Mother incapable of caring for child due to mental illness
  • Father had limited/sporadic visitation since birth
  • Father never had child overnight
  • Father never attended school events or medical appointments
  • Father never paid child support

The grandmother was awarded visitation so the child could spend time with both grandmother and a half-brother .

Visitation vs. Custody: Understanding the Difference

Visitation

Time spent with the child (scheduled visits, holidays, etc.) without assuming parental responsibilities. Lower legal threshold, but still requires overcoming the fit parent presumption in many states .

Custody

Legal and physical responsibility for the child. Requires showing that parents are unfit or extraordinary circumstances exist. Much higher legal standard .

Common Scenarios for Grandparent Visitation Petitions

Parents Divorced/Separated

Parent Deceased

Parent Incarcerated

Parent Missing/Absent

Parent Mentally Incompetent

Child Lived with Grandparent

Extraordinary Circumstances: When Grandparents Can Seek Custody

Courts require proof of extraordinary circumstances before awarding custody to a grandparent. These include:

  • Parental unfitness due to alcohol/drug addiction, crime, mental illness, neglect, or abuse
  • Both parents deceased and grandparents named guardians in will
  • Extended parental incarceration (90+ days in Illinois)
  • Abandonment or prolonged absence
  • Child Protective Services investigation placing child with grandparents for safety
  • Child's preference (if mature enough)

What Courts Consider in Grandparent Rights Cases

Quality of existing relationship — length and nature of bond
Child's preference — taking into account maturity and ability to express reasoned preferences
Stability of grandparents' household — including physical and financial ability to care for child
Physical and mental health — of both grandparents and child
Geographic considerations — impact on child's school and community
Parents' reasons for denial — good faith of both parties
Potential for family conflict — minimizing child's exposure to adult disputes
Harm from loss of relationship — Illinois now explicitly requires consideration of whether loss of relationship is likely to harm the child

How to Petition for Grandparents' Rights: Step by Step

Attempt Informal Resolution & Mediation

Before filing legal action, try working out an agreement with the parents directly or through family mediation. This can be less adversarial and more cost-effective .

2
Gather Documentation

Collect evidence of your relationship: photos/videos, receipts for expenses, school/medical records (if involved), witness statements from teachers, neighbors, or family friends .

3
Consult with Attorney

Family law attorneys can help you understand your state's specific requirements and whether you meet the legal threshold for filing .

4
File Petition in Correct Court

Typically file in the county where your grandchild resides. Include your relationship, current visitation status, reasons for seeking visitation/custody, and how it benefits the child .

5
Serve Parents with Notice

Parents must be formally notified of your petition. Your attorney can advise on proper service methods .

6
Attend Hearings & Make Your Case

Present evidence showing why visitation or custody is in the child's best interest. The burden of proof is on you .

Special Considerations: Death of a Parent

The New Jersey State Bar Association's 2026 Family Law Symposium addressed critical questions when death intersects with family law:

  • Custody, parenting time, and visitation issues that arise when one parent dies—do grandparents have rights? Do siblings?
  • Appropriate language in settlement agreements and wills to provide for a child's care in the event one parent (or both) dies after divorce

— New Jersey State Bar Association, Jan 2026

Special Challenge: Intact Families

Getting grandparent visitation or custody is extremely difficult when the child's family is intact. Parents have a legally protected right to raise their child as they see fit. Courts only intervene in rare instances when it's in the child's best interest .

For intact families, grandparents may have standing only when:

  • Parents are unfit (alcohol/drug addiction, crime, mental illness, neglect, abuse)
  • Child Protective Services is conducting an investigation

Grandparents' Rights in 2026

The legal landscape for grandparents' rights continues to evolve. Key takeaways:

  • The fit parent presumption remains paramount—courts presume fit parents act in their child's best interest
  • Visitation vs. custody have different legal standards; custody requires showing extraordinary circumstances or parental unfitness
  • 2026 legislation in Indiana, South Carolina, Florida, Maryland, and Illinois is expanding and refining grandparents' rights
  • Documentation is critical—gather evidence of your relationship, financial support, and involvement
  • Alternative dispute resolution may preserve family relationships better than litigation

Every state has its own statutes and requirements. Since 2025, all states allow grandparents to petition for visitation, but the specific circumstances vary significantly . Consulting with an experienced family law attorney is essential to understand your rights and the likelihood of success in your jurisdiction.
