i might can help a little. background first then explanation for context.
i filed a RO on one of my adult sons ex gf who was stalking him and additionally stalking my house where i live w my minor children ( and said adult son) and she vandalized his car in my driveway. after she had showed up late at night multiple times screaming and crying on my front yard at night, and vandalized his car i installed cameras. my final straw was when she literally chased two of my sons (one her ex bf young adult son and one teen son) home in a truckful of dudes, i had enough. i called the cops. my son didnt want to involve the cops because he has repeatedly been pulled over for no reason and just doesnt like them, but at this point is was too close to my home w my minor children.
so since i was not the party w the previous relationship w her, i was unable to file a DVRO and had to file a civil one, and i could add family but not the son whose ex gf she was, he would have to do the DVRO for himself. im thinking that KM's mom didnt want him near her house and KM may not want to be involved directly.
