I need to modify a child support order in Massachusetts at this time neither of my kids ages 22 and 19 live with my ex but she's still collecting child support one of my daughters is in the armed forces is this going to be a complicated mess? I was thinking about trying to do this myself without and attorney any suggestions ( DOR is involved)

It should not be that hard, but I would do it with an attorney

I would never advise someone to go before a judge (except small claims court) without an attorney. But this should be pretty straight forward.
