At Provident Law®, we understand that family dynamics can be complex—especially when a grandparent, relative, or close family friend steps in to care for a child. Arizona law recognizes these relationships through the legal concept of in loco parentis, allowing third-party non-parents who have formed meaningful, parental bonds with a child to seek visitation or custodial rights under certain circumstances. Whether you’re navigating a difficult family transition or seeking to protect a child’s well-being, our experienced Scottsdale family law attorneys are here to guide you through your legal options with clarity and compassion.
Understanding In Loco Parentis Rights
In loco parentis is a Latin term that refers to a situation in which a third party, not a biological or adoptive parent, assumes the role of a child’s parent. A.R.S. § 25-401(1) defines “in loco parentis” as “a person who has been treated as a parent by a child and who has formed a meaningful parental relationship with a child for a substantial period of time.” The definition of in loco parentis makes no distinction between a grandparent, another relative, or any third party. Therefore, in seeking in loco parentis rights to a child, a grandparent is on the same footing as any other relative or third party.
Grandparent & In Loco Parentis Visitation Rights
Who May Seek Visitation Rights
A grandparent or any third party may seek visitation rights during the child’s minority on a finding that the visitation is in the child’s best interests and that any of the following is true:
- One of the legal parents is deceased or has been missing (as per a law enforcement agency) for at least three months.
- The child was born out of wedlock, and the child’s legal parents are not married to each other at the time the petition is filed.
- For grandparent or great-grandparent visitation, the parents of the child have been divorced for at least 3 months.
- For in loco parentis visitation, a proceeding for dissolution of marriage or for legal separation of the legal parents is pending at the time the petition is filed.
Factors for Consideration in Granting Third-Party Visitation
In determining whether to grant visitation to a third party, the court must consider the following factors, including giving special weight to the legal parents’ opinion about whether visitation would serve their child’s best interest:
- The historical relationship between the child and the third party.
- The motivation of the third party seeking visitation.
- The motivation of the person objecting to visitation.
- The quantity of visitation time requested and the potential adverse impact that visitation will have on the child’s customary activities.
- If one or both of the child’s parents are deceased, the benefit in maintaining an extended family relationship.
- If logistically possible and appropriate, the court shall order visitation by a grandparent or great-grandparent if the child is residing or spending time with the parent who is his or her child or grandchild.
However, if a grandparent or third party is granted visitation, those visitation rights automatically terminate if the child is adopted or placed for adoption. The only exception is if the spouse of a natural parent, or a stepparent, adopts the child. In that case, third-party visitation rights survive the adoption.
Grandparent and Third-Party Custodial Rights to a Child
Various circumstances can lead a grandparent to file for custodial rights to a child. A parent may leave a child in a grandparent’s care for an extended period with little or no contact. The children’s parents may be unable to care for a child due to substance abuse, housing instability, criminal charges, or mental health issues. In these situations, a grandparent may need to seek third-party rights to a child, typically to allow that grandparent to care for, parent, and make decisions for the child. Third-party rights may also be needed to protect a child from unfit parents in some situations.
Legal Decision-Making Authority and Placement
Under A.R.S. § 25-409, a grandparent or another third party can petition the court for legal decision-making authority or placement of a child. A.R.S. § 25-401(3) defines “legal decision-making authority” as “the legal right and responsibility to make all nonemergency legal decisions for a child, including those regarding education, health care, religious training, and personal care decisions.”
On the other hand, “placement” refers to a child’s primary residence. Although “placement” is a word that professionals often use to refer to a child being in foster care or an adoptive home, it can equally apply to any situation in which a child is primarily living with a grandparent or third party.
Requirements for Seeking Third-Party Rights
For a grandparent or any third party to seek either of these rights concerning a child, all the following factors must be true:
- The grandparent stands in loco parentis to the child.
- It would be significantly detrimental to the child to remain or be placed in the care of either legal parent.
- A court has not entered or approved an order concerning legal decision-making or parenting time within the past year, unless there is reason to believe the child’s present environment may seriously endanger the child’s physical, mental, moral, or emotional health.
- One of the following applies:
- One of the legal parents is deceased.
- The child’s legal parents are not married to each other at the time the petition is filed.
- A proceeding for dissolution of marriage or for legal separation of the legal parents is pending at the time the petition is filed.
Arizona law presumes that awarding legal decision-making to a legal parent serves the child’s best interests. The reason for this presumption is that the physical, psychological, and emotional needs of the child are best met when a legal parent is raising the child. However, a third party may rebut this presumption by clear and convincing evidence that awarding legal decision-making to a legal parent is not in the child’s best interests.
