namechanged regular here.
Back in November FIL shouted at and roughly handled our 6yo DD. We cut off contact. Today we received a letter from FIL and MIL stating that if we don't let them see DD they'll "go down the legal route to secure regular access to her". They are loaded so can afford lawyers. We are not.
Do they have rights? What can they do? The injury to DD was minor, although she was really shaken. We didn't involve the police or anything like that.
Please help. I'm beyond furious but also very worried.
