DH filed a Petition in family court Against BM. After the petition was filed by DH some new incriminating evidence came to light that was NOT in the Petition. DH called the court about the process of getting this new information added on to his Petition. The person on the phone said ALL DH needs to do is email All parties involved(BM, BM's Attorney and the court). No other paperwork to fill out or anything. 

So my question is was the person DH spoke with on the phone correct? To make an Amendment to the Petition all DH needs to do is email the Additions to all parties involved? To me it just seems there would be more to it.
