Hello. I am in Minnesota. All parties referred to here are. So, my daughter had a child out of wedlock, born in April of 13. In May (roughly) of 14, she stared seeing a girl. In September of 14 they moved out of state and we were no longer allowed to see our granddaughter. In February of 16, contact was reestablished. In roughly March of 16, my daughter and her girlfriend, who is now going through gender-reassignment surgery, broke up. My daughter started seeing someone new. The ex's parents asked to still be able to visit the child, and a set of rules was put in place. The ex's mother broke one of the rules, and visitation was stopped. The ex's family is now threatening to sue for court ordered visitation. What is the likelihood of them getting it?
