Hi. I've recently been to conciliation, which failed due to other side choosing to ignore existing joint liabilities. The highlights are: ex has brain tumour and has not worked for sometime, he served papers on me based on a 50/50 split. I have 85% care of the three young children. He needs to get out of his current residential property owned by his brother. He wants to move in the jointly owned property next to me. The issue is that my 11yo daughter is already currently getting counselling and had has recently started 'cutting' herself. I strongly feel that having their ill father right next door will be overwhelming for the kids and near impossible to keep a routine with the kids. I also strongly feel that it will become a popularity contest with the kids. It will be near impossible enforce discipline if required, or maintain boundaries as they will simply run next door (either way) if they don't like what is happening. This opinion has been confirmed by my daughter's psychologist. My query is: what are my legal rights under family law in relation to this? A family court date is likely to be set towards the end of 2015. Can I prevent him moving in? What would be the negative implications of me moving out of the family home (5years)? The kids are 11, and twin boys 9. Thank you for any help.
