I filed a stop claim/bond notice. We just got paid, what document do I request to release this filing?

You will want to record a Release of Mechanic's Lien with the County Recorder's Office you filed the mechanic's lien in. You'll want to do this promptly - if the homeowner is forced to ask the court to expunge the lien, you could be assessed a monetary fine. Levelset has a sample form you can use: https://www.levelset.com/lien-release/california-mechanics-lien-release-form/
