Can I please have help on a question? I'm about to have mediation and want to request that my children have their own room at their father's. We recently separated and he is still living in our owned home. My ex currently has an ad on gumtree and Facebook looking for a flatmate. The ad is saying they'll have access to the whole downstairs which were the kids' rooms. This means my kids will have no rooms there. They're 12, 4 and 3. My 3-year-old also has asthma and he's put that smoking is permitted on the ad. Does anyone know where I stand under family law?
