My baby's father (who is married) runs own business and promised to hide his income. Can his wife's earnings be garnished?

The wife has NO legal obligation whatsoever to support a child fathered by her husband. On the other hand, the birth mother can file a motion in family court for support and if she has an order and the father does not pay, she can file a motion for contempt of court + incarceration. It also helps if she hires a detective to find out true wotth of the father.
On my profile there are several legal guides. I recommend reviewing the following which may be helpful to you:


Hiring a lawyer; Is it Legal? Is it Illegal?...Understanding the different court systems;
Legal terms used in litigation………………………………………………………..


Divorce in General and How It's Handled in New Jersey (some of this is applicable to unmarried parents).

FYI my law partner James DeFelice practices family law in your part of NYS. You can access his contact information on his avvo profile or on our firm’s website: www.sarnoanddefelice.com
