I have a couple of stupid questions: how does a court know what exactly i mailed to my ex, if certified mail is an appropriate way of giving notice in MA? Not that i'm planning to send anything other then a copy of my petition, but still? Also, can i send him a notice of petition for child's name change before filing it in court or it has to be done after i file it? Should be after filing, i guess, but i want to make sure. Thanks!
