How do you legally stop your partners ex from lying to his children about you Saying things like you want 'her dead and buried' so as to scare the children not to come with us?

Answer 1

You really can't. Because in all honesty this is not illegal, so you can't make it a legal matter. All you can do Is talk to your parents ex or his children and hope it works out. I'm sorry your having family issues, wish I could help more :/
