<p>If your father did not sign any paperwork associated with your mom's welfare application, then he will probably not get into any trouble, simply because it would be difficult to prove that he knew about or had a part in what she was doing ... so it's unlikely that authorities would attempt to prosecute him. But as a practical matter, it seems like he would have known. If there is evidence that was involved or benefitted directly from the fraud, such as if your mom deposited one or more of her TANF checks into your dad's bank account, then he could get in trouble. I think he must bear some responsibility, as I don't understand why he did not do anything to stop your mom. </p>
<p>I can see that you are in a tough situation. The welfare mess is something that the adults in your family -- yoru parents -- need to deal with and straighten out. As you are thinking about college and your future, please do not make it your problem as well -- if you file a FAFSA, then make sure that it is filled it out fully and truthfully.</p>
