yep. hubs had to move heaven and earth to find out if his estranged-by-his-ex daughter was still in community college (thus extending child support till age 24, wink, wink)
She dropped out in the first semester due to zero discipline instilled as a child by his alienating ex-shrew. It was quite challenging to find that out. She emancipated from child support shortly before the mandatory cut off of age 21.
It’s his fault for not nurturing a relationship with his own daughter.
Sometimes...might not be fair...but you use the tools you have.
