MO SB910

Allows child support obligation to abate (reduce or eliminate) when the other parent voluntarily relinquishes physical custody for more than 30 consecutive days, regardless of scheduled visitation or custody arrangements.

Permits parents with joint physical custody resulting in substantially equal time with both children to either waive child support entirely (if both agree and income difference is less than 25 percent) or receive up to a 50 percent reduction below standard guidelines.

Requires Missouri Supreme Court to amend child support guidelines (Form 14) to reflect the ability to obtain up to 50 percent adjustment for joint custody arrangements.

Establishes that child support guidelines must require income documentation including wage stubs, W-2 forms, employer statements, wage match data, and bank statements for initial orders and modifications.

Permits automatic termination of child support obligations when the child reaches age 21 (if order specifies) or through sworn statements/affidavits of emancipation filed with the court or family support division.
