Custody in Washington is decided in the Superior Court, usually in the Family Law. Most states split the question in two: who makes the big decisions for the child, and what the day to day schedule looks like. Both usually end up written into one order or parenting plan the judge approves.
The wording differs from state to state, so read the official Washington documents below rather than assuming a term you heard elsewhere means the same thing here. Courts decide these cases on the best interests of the child, and the official forms are written to collect the facts a judge needs.

Custody decisions are made on the best interests of the child, not on which parent asks first. Judges look at things like stability, each parent's involvement, the child's needs, and whether a parent supports the child's relationship with the other parent. Read the official Washington forms and self-help material for the factors this state asks about.
Many courts send custody disputes to mediation before a hearing, and some require it. The official Washington mediation page linked above explains what this state offers and when it applies.
