It’s important that children are not asked who to choose between and should avoid exposure to conflict at all costs. However, as children get older they are more likely to want to have a say in where they live and who they spend the majority of their time with. This can be achieved by parents listening to what their child/children want and adapting to changes of arrangements.
However, if the Court has to take control and decide what’s best for the child then their wishes and feelings would be relevant, depending on their age.
