Child Custody Laws for Unmarried Parents

Attorney Serving St. Louis, St. Charles, & Chesterfield

While child custody, visitation, and child support are often linked to the divorce process, parents who were never married have the same rights to seek these things for their children. When it comes to a child’s right to have the care and support of both parents, Missouri family law statutes and court cases do not distinguish between married and unmarried parents.

At Cavanagh & Associates, we help unmarried parents in Chesterfield, St. Charles, and St. Louis with:

  • Establishing legal parent-child relationships (usually paternity);
  • Establishing initial child custody orders;
  • Establishing child support orders;
  • Modifying custody, visitation, and support orders; and
  • Resolving disputes about child custody, visitation, or support.

Missouri Custody Laws for Unmarried Parents

In Missouri, if a child is born to unmarried parents, then the mother is automatically given sole custody with full parental rights. That is unless the mother signs an affidavit acknowledging that her partner is the father. If the mother refuses, then the father must establish paternity via DNA test or court petition. If the father does not establish paternity, then he will not be able to make decisions on behalf of the child such as healthcare, education, religion, etc. However, once the courts have validated the petition for paternity, the father is given rights equal to that of the mother and can seek custody and visitation. It is important to remember that courts will favor joint custody of a child, especially if they feel it's in their best interests. Seeking sole or full custody is often difficult to do without sufficient evidence of one of the parents being unfit.

Paternity & the Rights of Unmarried Fathers in MO

A paternity case is a legal action to determine and declare a father-child relationship. If the mother and father agree to the biologic facts of parentage, they may jointly submit forms to the Missouri Department of Health and Senior Services, Bureau of Vital Records. However, if there is a dispute or if one of the parents refuses to cooperate, it may be necessary to file a paternity action in court.

Establishing the parent-child relationship is required before a person who claims or who is alleged to be a parent can be granted custody or visitation rights and before support obligations can be established or enforced.

Although paternity can be established by genetic testing, it may not be necessary in all cases. Paternity can also be determined by agreement of the parents, including an affidavit signed by the child’s father in which he admits paternity.
