In Washington, children do not get to choose where they live.
In general, it is the policy in this State that children should not be put in the position of having to make this decision. This can lead to manipulation of the children by the parents.
Further, it is believed that children do not necessarily understand all of the implications of deciding where to live. It is up to the parents to come to an agreement on the residential arrangements of their children, and if they are unable to do so, the court will make a decision for them.
