Washington Revised Code Title 26. Domestic Relations § 26.09.540. Objections by nonparents

A court may not restrict the right of a parent to relocate the child when the sole objection to the relocation is from a third party, unless that third party is entitled to residential time or visitation under a court order and has served as the primary residential care provider to the child for a substantial period of time during the thirty-six consecutive months preceding the intended relocation.
