Maximum claim
You generally file where the other party lives, not where the dispute happened.
Courts do not allow one dispute to be filed as several in order to beat the maximum.
What this court awards is a sum of money, not an instruction to act or to hand something back.
In Washington's district court small claims department, no attorney or legal paraprofessional may appear or participate in the prosecution or defense of a case without the consent of the judicial officer hearing it. A narrow exception under RCW 12.40.025 lets an attorney who was already the attorney of record continue representing a party when a case is transferred from district court to the small claims department.
A claim involving a minor is brought by a court-appointed guardian.
Over the limit? Two routes exist: reduce the claim to the cap and stay here, or take the full sum to regular civil court. Reducing it normally forfeits the difference.

Once the case is on file, the law requires the other side to be told about it formally. That step is service of process, and the papers cannot normally come from your own hand. In Washington, courts typically use delivery arranged by the court or email service where the court allows it.
The options usually include a sheriff or constable, a licensed process server, certified mail sent by the clerk, or any adult with no stake in the case. What is allowed, and what it costs, differs from county to county.
Every court fixes a minimum number of days between service and the hearing. The clerk will tell you what it is for your case. Service: 10 days before hearing (in-county), 13 days (out-of-county). Proof of service filed before hearing (or bring to hearing).
Service is proved on paper. The server completes and signs a form, and it is filed before the matter is heard.
Service is where many self-filed cases stall. Squabble can coordinate professional Service of Process so it's done correctly and on time.
