If someone was laid off from work and they are behind on child support and would like to have the amount they pay in child support reduced can a lien be placed on their property, like their home, car bank accounts? They have started back to work and they are starting to pay support, will their effort make a difference in a court hearing?

There are various methods that can be used to collect arrears.

If they were laid off, they should have filed for a modification of the support order. But if they fell into arrears because of a reduction in income, and as soon as their income came back up they started to repay the courts would take that into account.
