Grandparent Visitation Rights in Illinois
When a grandparent can ask a court for visitation with a grandchild in Illinois, who has standing to file, what they must prove, and the special weight the court must give a fit parent's decision. Cited to the statute.
When a grandparent can petition in Illinois
The situations that give a grandparent standing to file, and the limits the court applies before it orders visitation over a parent's objection.
Grandparent visitation statutes are frequently litigated and amended after constitutional challenges under Troxel v. Granville. Confirm the current text of 750 ILCS 5/602.9 and recent Illinois case law before relying on this.
| When a grandparent can petition | What it means |
|---|---|
| A parent deceased or missing 90+ days | A grandparent has a standing condition when the child’s other parent is deceased or has been missing for at least 90 days. This is one of several gates that must be met before the court looks at harm and best interest. |
| A parent incompetent or incarcerated | Standing also exists when a parent of the child is incompetent as a matter of law, or when a parent has been incarcerated in jail or prison for more than 90 days immediately before the petition is filed. |
| Parents divorced or legally separated | A grandparent may petition when the parents are divorced or legally separated, or a dissolution or parental-responsibilities proceeding is pending, as long as at least one parent does not object to the visitation. |
| Unmarried parents not living together | Standing exists when the child was born to unmarried parents who are not living together, and the petitioner’s relationship to the child is legally established. |
| Unreasonable denial that harms the child | On top of a standing condition, the grandparent must show the parent unreasonably denied visitation and that the denial caused the child undue mental, physical, or emotional harm. Both parts are required. |
| What blocks or limits visitation | What it means |
|---|---|
| Presumption a fit parent’s decision is not harmful (Troxel) | There is a rebuttable presumption that a fit parent’s decisions about visitation are not harmful to the child. This is how Illinois gives special weight to a fit parent under Troxel v. Granville. |
| The burden is on the grandparent | The party filing the petition must prove that the parent’s decision will cause the child undue mental, physical, or emotional harm. A simple disagreement with the parent’s choice is not enough. |
| The family being intact is a bar | The statute does not give standing when two parents in an intact family both object. The standing conditions all involve a death, an absence, an incapacity, or a separation of the parents. |
| Adoption can cut off standing | Adoption of the child changes legal parentage. Once a child is adopted, other than in limited situations, a grandparent generally loses the standing the statute relies on. |
What you can do right now
Concrete, neutral steps for a grandparent or a parent in Illinois. This is legal information, not legal advice.
- Confirm you fit a standing condition
Check whether a parent is deceased, missing, incompetent, incarcerated, or the parents are divorced or unmarried and apart. Without a listed condition, a petition under 602.9 cannot proceed.
- Gather evidence of the relationship and the harm
Because you must show an unreasonable denial and undue harm to the child, document the existing relationship and any concrete harm to the child from losing contact.
- Try mediation, then consult a family-law attorney
Mediation may restore contact without court. If it does not, a family-law attorney or the Illinois Lawyer Finder can explain the burden you would carry under 602.9.
Grandparent visitation is decided case by case and turns on standing and the child's best interest. A licensed family-law attorney can explain your options; the state bar can refer you to one.

What families in Illinois get wrong about grandparent visitation
Illinois lets a grandparent, great-grandparent, step-parent, or sibling petition for visitation under 750 ILCS 5/602.9, but only within tight limits. A petition may be filed only after a parent has unreasonably denied visitation and that denial has caused the child undue mental, physical, or emotional harm, and only if at least one standing condition exists: a parent is deceased or missing for 90 days, a parent is incompetent as a matter of law, a parent has been incarcerated for more than 90 days, the parents are divorced or legally separated with at least one not objecting, or the child was born to unmarried parents who do not live together. Even then, the statute creates a rebuttable presumption that a fit parent’s decisions about visitation are not harmful to the child, and it puts the burden on the grandparent to prove otherwise. That presumption is how Illinois gives special weight to a fit parent’s wishes under the U.S. Supreme Court decision Troxel v. Granville. When two fit parents in an intact family both object, the statute does not provide standing at all. This is legal information, not legal advice.
Common questions
Can grandparents get court-ordered visitation in Illinois?
Yes, in limited circumstances. Under 750 ILCS 5/602.9 a grandparent may petition after an unreasonable denial that harms the child, and only if a condition applies such as a parent deceased, missing, incompetent, incarcerated, or the parents divorced.
What must grandparents prove in Illinois?
They must show a qualifying standing condition, that a parent unreasonably denied visitation, and that the denial caused the child undue mental, physical, or emotional harm, all while overcoming the presumption that a fit parent’s decision is not harmful.
Can two fit parents block grandparent visitation in Illinois?
Yes. The statute does not give standing when two fit parents in an intact family both object, and it presumes that a fit parent’s decision about visitation is not harmful to the child.
Does adoption end grandparent visitation rights in Illinois?
Generally yes. Adoption changes the child’s legal parentage, and once the child is adopted, other than in limited situations, a grandparent loses the standing the statute relies on.
