Child support and spousal support are separate obligations, but they can affect the same household finances. When a child reaches adulthood and a California child support obligation ends, the financial circumstances of the former spouses may change significantly. Under California family law, termination of child support because a child reaches the applicable age can provide a specific basis for requesting modification of an existing spousal support order in qualifying circumstances.

Termination of Child Support Can Be a Change of Circumstances

Long-term California spousal support generally cannot be modified simply because one former spouse would prefer a different arrangement.

When support remains modifiable, the party requesting a change generally must establish a material change of circumstances since the previous order.

California provides a specific rule when spousal support and child support orders exist together.

If child support terminates because the child reaches the age specified under California law, that termination can constitute a change of circumstances upon which either former spouse may base a request to modify spousal support.

This does not mean spousal support automatically increases or decreases when child support ends.

Instead, termination of child support can open the door to a modification request. The family court must still determine whether a change to spousal support is appropriate under the circumstances.

There Is a Deadline for Using This Particular Rule

Timing is especially important.

A request to modify spousal support based on this statutory child-support termination rule must be filed no later than six months after the child support order terminates.

Waiting beyond that period can eliminate the ability to rely on this particular statutory basis for modification.

The court’s broader jurisdiction over spousal support may depend on the existing judgment and other circumstances, but the specific rule concerning termination of child support contains its own deadline.

The parties should therefore not assume that they can wait indefinitely after child support ends before raising the issue.

California law also allows either party, in connection with this type of modification proceeding, to request appointment of a vocational training counselor under the applicable procedures.

The Rule Does Not Apply to Every Support Judgment

The language of the existing judgment or marital settlement agreement remains critical.

Termination of child support does not constitute a change of circumstances under this particular statutory rule when the child and spousal support orders resulted from an agreement or judgment that already specifies what will happen when child support terminates.

The rule also does not apply when the agreement provides that spousal support is nonmodifiable or has been waived and the court’s jurisdiction over spousal support has been terminated.

Similarly, the statutory provision does not create a modification opportunity if the court’s jurisdiction over spousal support had already been terminated.

Other substantial changes in the amount of child support—short of complete termination—may potentially support a spousal support modification request under broader changed-circumstances principles, depending on the circumstances.

Child Support Ending Does Not Automatically Change the Spousal Support Order

The end of a California child support obligation can affect the financial circumstances underlying spousal support, and California law specifically recognizes qualifying termination of child support as a potential change of circumstances. However, the existing spousal support order does not automatically change. A modification must be properly requested, the applicable deadline must be observed, and the terms of the existing judgment or agreement can determine whether this particular modification rule is available.
