Legal Custody

People often use the terms “custody,” “guardianship,” and “adoption” interchangeably, believing that all three words mean the same thing. In the legal world, however, the types of child custody are very different. This guide explains how they differ.

What is Legal Custody?

Legal custody is the temporary legal right to make decisions for a child. The terms of a legal custody agreement can be changed at any point through a court order.

Definition and Common Use

Individuals who have legal custody of a child can make decisions regarding their welfare, such as where they will go to school and when they should receive medical treatment. In a divorce or separation, one parent may receive what’s known as sole custody. Joint custody refers to arrangements in which both parents can legally make decisions for the child.

Key Fact: Parental Rights Remain

A custody agreement does not terminate one parent’s rights; it simply determines which parent temporarily has certain rights. Custody agreements are not permanent, and they can be changed in court at any point. Parents who do not have a court order have joint legal custody, and can make decisions regarding their child on their own terms.

What is Legal Guardianship?

Legal guardianship lets a parent give a court-assigned caregiver legal rights over their child for a period of time, without relinquishing their parental rights.

Definition and Common Use

When a parent or parents cannot care for their child due to incarceration, illness, or other long-term situations, a family court may give an assigned caregiver legal guardianship over the child. The legal guardian may make decisions regarding the child’s welfare.

Legal guardianship is common when a child goes into kinship foster care. The situation allows the child to have a legal relationship with their guardian, while their parent retains parental rights.

Key Fact: Parental Rights are Suspended, Not Terminated

Like custody agreements, guardianships can be temporary. Because the parents suspend their parental rights instead of terminating them, they can always choose to end the guardianship if it is no longer needed. A parent who is in prison, for example, may end the guardianship when they are released.

What is Adoption?

Adoption is the legal process of bringing another person’s child into one’s home to care for as one’s own.

Definition and Common Use

When an individual adopts a child, they permanently become that child’s only legal parent. The child’s biological parents’ rights are terminated, and the adoptive parent receives full legal rights over the child. Once the birth parents give their consent or their rights are terminated, the adoption is permanent and cannot be revoked.

Key Fact: Requires Termination of Parental Rights

Unlike legal custody and guardianship, adoption requires the termination of parental rights (TPR). Of the three, it is also the only permanent option. When a child is adopted, the court awards their adoptive parents full, permanent parental rights.

TPR typically occurs when a birth mother relinquishes parental rights to her infant at birth. TPR can also happen in cases of parental neglect or abandonment.

Which is Right? Consult a Family Law Attorney

Family law situations can be complex, and adoption is the only way to gain permanent custody of a child. If you’re unsure of which pathway is best for your family, a family law attorney can help you explore your legal options.
