Does Closing Child Support Discontinue Modification

by Ms. Just Due
(VA)

A child support order is in place set by my divorce decree. CSE has a modification case in process on behalf of my ex (it hasn't been 36 mths since the initial order began) because he claims to be unemployed (over a year) after losing his high paying job and has another kid to deduct from what I'm ordered to receive. (A ploy to lower my support - he is well educated and has high-earning potential)

If the enforcement case is closed by me, will that discontinue any court hearings scheduled for this modification? Payment is being received although not the full original ordered amount and has been attached by CSE to his retirement pay.
