If opposing counsel, or other attorneys on my case, are eFilers in a case, must I still use conventional service methods to ensure my documents are delivered?

No. Upon the electronic filing of a document, the court's eFiling system will automatically generate and send a Notice of Electronic Filing (NEF) to all eFilers/parties associated with that case, along with a hyperlink to the electronic document. Transmission of the NEF with a hyperlink to the electronic document constitutes service of the filed document under CR 5. No other service on those parties is required.

Parties not registered as eFilers must be served through conventional methods.
