my daughter's father has been approved for disability from Social Security. She recieves a beneficary check that I manage because I have custody. Does this count as a child support credit for him and if it does why since it does not cost him anything and if she did not exist he wouldn't have that money??
The SS dependent check you receive for your daughter "may" satisfy his child support obligations. It is up to the Child Support Judge to decide this. It the disability is his only income then the SS dependent check you receive may very well be considered enough to satisfy his obligation. You need to talk to a family law lawyer in your state.
There are two issues here. The first is the fact that your daughter receives a SS check because the father is disabled. The second question is the amount of child support that he is ordered to pay. At the time that the child support was ordered the father may have been working and therefore receiving more money but now that he is not working he is not able to pay as much. In Florida where I practice I tell clients that the amount of SS benefit that the child receives will be considered a credit by the Family Law Judge but that alone may not completely satisfy the child support obligation. I also tell the non-disabled parent that a modification of the child support obligation may be in their future. I hope that this helps.
