I need some advice and I'm not sure what to do
I split up with my ex partner last may 2017, since then he's had supervised contact due to his alcohol and drug issues. During this time his mother has repeatedly either made comments about my parenting, or accused me of keeping my daughter from contact to my sister in law. Even when my sister in law tells his mother to talk to me about it she refuses and keeps messaging my sister. She's already had one warning from the police about harassing me. I suspect she's also called social services on me in January. She is refusing to leave my sister in law alone. I don't know what to do next.
My ex-dp also wants unsupervised contact, and is apparently making the steps to attend counselling and such for his alcohol issues, after he repeatedly rang my sister in law drunk & high on drugs at 5am asking to see the kids. He's high functioning aspergers. Would it be unreasonable to ask for proof he's been attending his counselling before I even think of giving him unsupervised contact & can I take him to court for a CAO or do I need to wait for him to take me to court to do so?
