Asking for a friend here....
DFriend is married and her DH's young son lives with them. He sees his DM every other weekend and one day in the week on the weekends she doesn't have him. This has also been done as an agreement between both parents, courts have never been involved and there is nothing in writing.
There have been some issues recently which are making my DF and her DH anxious about the fact that nothing is formalised. How do they go about putting the residency and contact arrangements in writing? Does it need to involve a solicitor and lots of money because they can't afford that?
