Do you have proof? And what was it that you thought he perjured himself with? I have posted that same question, but I have solid proof. My ex for the last 6 years has filed a false Financial Statement and w2 to Family Court. He claimed he only made $50,000 a year. We just found out, (because he was ignorant to just buy a $300,000 house) he is making $186,000. Which has affected my child support payments substantially.
So my lawyer is going after him for perjury charges. Also, he never listed his business as an asset. He is a co-owner. They are making over 3 million a year and he has only 19 employees and rents his building. I hope this helps.
