Long story but my db does seem to have some mental health issues and recently had an argument with my dh where db threw a glass of wine over dh (see my previous thread - don't know how to link it). Db now hates dh and has just sent me a message to request that I undertake never to let his dd visit if dh is present. If I don't agree to this he has stated that he will issue a writ to stop this happening. He does not have custody of his dd - she lives in another country with his ex (who I get on ok with). He will not currently accept my calls to try to talk to him.
Any legal experts out there? I am tempted to tell him to go ahead and issue whatever writs he wants.
