yes
My ex husband was in an accident and has not paid child support for 27 months. He is now drawing SS benefits which my child just started to receive benefits, his step-child is receiving the other half of the benefits. However, these benefits are less than what he was paying in child support
If the custodial is the father, he pays support, even with sole custody.
That should have no effect.
No, but he can be fined and jailed.
You can file for modification on the basis of a lower income. You cannot file for reduced child support because she is now married, though you could use that as a basis to terminate alimony.
You should file a motion for modification in the court that issued the child support order immediately.
For the same reason everybody else pay child support - to support your child! Just because one parent is a illegal alien does not make the child any less yours.
Probably not, given that the new marriage does not terminate the child's father's legal responsibility to support the child.
It should not lead to an increase in child support. It may lead to a decrease. The cost of supporting three children is significantly less, per child, than the cost of one child. There are many savings that are achieved by sharing. A simple example. To take the child on vacation by car costs $x for the travel and $y for the accommodation. But if you take 3 children, the transport costs are less (per child) and the accommodation costs are less (per child). Also, with three children to support, the family living standard will be slightly lower than the standard they could achieve with one child. So costs per child drop. It is unlikely that a court would force you to pay as if your child was the only child.
whoever keeps the child the less amount of time
Because the state provides most of the support for an incarcerated child, a taxpayer may not claim a child if the taxpayer provides less than one half of the child's support.
If that is the only child you share, then you will have to pay him child support. If there are two children, then you two will break even and no one will pay child support. If there are more than two children, then the amount of support will have to be re-calculated and he should pay you less.
