Child custody (also known as legal custody, conservatorship, or allocation of parenting time and responsibilities) refers to the legal possession, rights, and responsibilities for a minor child by the child’s birth or adoptive parents—including the right to make health care, religious, cultural, and education decisions about the child's upbringing.

During separation, and following divorce, a child’s natural parents often share custody of the child (shared custody or joint custody)—unless one or both of the child’s natural or adoptive parents are deemed to be unfit or pose a risk to the health, safety, and well-being of the child (the child’s best interests). If one of the parents is deemed unfit, the other parent may be awarded sole custody of the child. In some cases a parent who is not allowed to have custody of a child may be given visitation rights—sometimes under the supervision of another adult (supervised visitation). Child custody laws are usually located in your state’s statutes governing family and domestic matters, and may be referred to as the Family Code.

Child custody is distinct from guardianship of a child, which usually involves a relative or an unrelated person temporarily agreeing to take responsibility for a child following the death of the child’s birth or adoptive parents, or their abandonment. And adoption is taking full and permanent responsibility for a child by someone other than the child’s birth parents.

In Wyoming, child custody laws are designed to ensure the best interests of the child are the primary concern in custody decisions during separation or divorce. Custody can be categorized as legal custody, which involves the right to make major decisions about the child's life, and physical custody, which pertains to where the child lives. Wyoming courts may grant joint custody, where both parents share responsibilities, or sole custody to one parent if the other is deemed unfit. Factors considered in determining custody include the child's wishes (if of sufficient age and maturity), the quality of the relationship with each parent, the parents' ability to provide care, and any history of abuse or neglect. Visitation rights may be granted to the non-custodial parent, which can be supervised if necessary to protect the child's welfare. These laws are found within the state's statutes governing family and domestic matters. It's important to note that child custody is different from guardianship or adoption, which involve different legal processes and standards.
