Child Support Past 18 in Mississippi: Emancipation at 21 and the Earlier Events

By the FigureMyTax Editorial Team · How we calculate

In Mississippi, child support runs to 21 unless the judgment says otherwise, and ends earlier on marriage, full-time military service or a felony sentence of two years or more; a court may also find emancipation if a child over 18 leaves school and is not disabled.

What is the child support age limit in Mississippi?

Twenty-one. The duty of support of a child terminates upon emancipation of the child, and unless the underlying judgment provides otherwise, emancipation occurs when the child attains 21 (Miss. Code 93-11-65(8)(a)). That is later than in most states, which end support at 18 or 19.

What ends support before 21?

Unless the judgment says otherwise, emancipation also occurs when the child marries, joins the military and serves on a full-time basis, or is convicted of a felony and sentenced to incarceration of two years or more (93-11-65(8)(a)).

Can a court find emancipation earlier?

Yes, unless the judgment provides otherwise. The court may determine that emancipation has occurred and no other support obligation exists when the child, having attained 18, discontinues full-time enrollment in school (unless the child is disabled); voluntarily moves from the custodial home, establishes independent living, obtains full-time employment and discontinues educational endeavors before 21; or cohabits with another person without the approval of the paying parent (93-11-65(8)(b)).

Does a Mississippi court have to decide?

For the automatic events, no; for the court-found events, yes. If the other parent disputes an event, ask the court to decide and bring proof, such as a marriage certificate, enlistment papers or school records.

What about a Mississippi child in jail?

The duty of support of a child who is incarcerated but not emancipated is suspended for the period of the child’s incarceration (93-11-65(8)(c)).

Where is the emancipation rule written?

In Miss. Code 93-11-65(8)-(9), the same section that gives the chancery court jurisdiction over support. A judgment can opt out of its defaults, so read your judgment first (the statute).

Can the other parent say the child left school?

Yes, and the court decides. Bring enrollment records showing full-time attendance. A child who returns to school or never left is not emancipated on that ground.

Can the amount change before 21?

Yes. A modification can be sought on a material change, with notice fixing the start date (Miss. Code 43-19-34), and a change in the number of children covered is a common reason to recalculate the percentage.

Does the 21 rule apply to orders from other states?

A judgment from another state arising by operation of law is given full faith and credit in Mississippi (93-11-71(1)(b)), but the end age for an out-of-state order depends on that order, so read it.

Do I have to file to end child support at 21?

The statute ends the duty at emancipation, but withholding keeps running until it is stopped. Ask the court or DHS to end it in writing and keep proof of the child’s birth date. See how to modify child support in Mississippi.

Do arrears end when child support ends?

No. A determination of emancipation does not terminate any arrearage; it stays owed until satisfied in full (93-11-65(9)). See the Mississippi child support arrears calculator and how long arrears last.
