Can I refused to sign it?

 


If you have been ordered to sign, and you refuse, then you are violating the order of your family court judge.  The IRS doesn't care, because the IRS follows federal law.  But judges have considerable power to enforce their orders and can make your life very unpleasant if you refuse to follow their orders.  I would not recommend violating a court order unless you have competent legal advice telling you to do so.
