There should be a periodic accounting of the use of the funds as part of the settlement, to assure that they are spent on the children.
If the kids are housed, fed, clothed, have basic utilities, transportation, and medical and dental care, it seems to me obvious that the child support of that amount is indeed being spent.
Child support in the tens of thousands is ridiculous IMO. Call it alimony that is what it is.
If the above basic needs are not being met sue for custody due to neglect.
Courts don’t require it....believe me
