I (28) live in England and need advice regarding child contact and safeguarding. I have two children (ages 3 and 6) with my ex "John" (35).
We split 1.5 years ago on fine terms.
John also has two older children (10 & 12) with his ex "K" (30). K and I are on good terms.
John, K and I have no prior history with police or Social Services.
John has been with his new partner "Jane" (23) for a year. Jane has a 2-year-old child. Over the past year, several major safeguarding and behavioral issues have emerged regarding Jane:
-Jane lives in a Mother & Baby Unit and has active SS involvement due to safeguarding issues. SS banned John from being around Jane’s child after learning he smokes weed (on his balcony). John and Jane repeatedly breached this restriction. Recently, they were caught, SS briefly removed Jane's child and placed him in the father's care, but returned him. John openly admits he ignores SS rules because he doesn't agree with them.
-Jane messaged me telling me to "do one" for co-parenting with John. She also wanted John to stay on the phone the entire time he was providing childcare at K’s house, and expressed that she wants him to financially/emotionally support her son and have her son call him "dad."
-During an argument where John tried to leave her flat and had to physically move past her, Jane called the police claiming domestic violence. John was arrested, but police took No Further Action. John has no prior history of ever being violent toward me, K, or anyone else. Out of malice, Jane then reported John and K to SS for child neglect (NFA’d after investigation). Jane later admitted in a call to SS that she lied.
Despite all this, John rekindled the relationship.
Current Situation:
John previously had a 1-bed flat where the kids stayed overnight 3 weekends a month, but he gave it up. He now only sees his children for a couple of hours each week, either on a weekend or after work in the week. He has now pretty much confirmed he will be moving in with Jane.
Both K and I are extremely uncomfortable with our children being around Jane due to her volatile behavior, false allegations, and disregard for SS rules. John says he will seek legal advice about Jane being around the children, claiming "she apologised, everyone makes mistakes."
Questions:
What options do K and I have to legally stop John from bringing our children around Jane or into her home?
If John takes us to court for a Child Arrangements Order (CAO), how will a court/Cafcass or Social Services view Jane’s ongoing SS involvement, her history of false reports, and their intentional breaches of SS rules?
How likely is a court to rule that our children can or cannot be around Jane given this background?
What immediate steps should K and I take to protect our legal standing while still offering safe contact between John and his children?
We want our children to see their dad regularly, he has always been a good, present dad before Jane came into his life.
