My brother is divorced and awaiting sorting the marital home and finances. He sees his children every other weekend but as he cannot accommodate as he doesn't yet own or able to afford his own place whilst the ex remains under the family roof . he collects them and spends the sat and Sunday all day with them. He does however offer to stay over night at his marital home so the ex gets a break as long as she stays out over night this is to avoid any arguments on her return and give the kids quality time.as he is still part owns the marital home he has legal rights to stay. His ex wife demands pick up time and drop off time and if she isn't wanting or able to stay out overnight dictates what time she will return and expect him to babysit until she roles in after a night out. This he won't do as he lives 65 miles away and is then expected to return again Sunday morning to collect again for the day. As no legal arrangements have been made yet and taking into account he only has a bedsit rental and can't accommodate is his ex being unreasonable ?
