The filing fee for filing an application for entry of judgment is currently $435 in most counties. The time to prepare the application and notice of entry of judgment is typically around an hour when the client has a certified copy of the judgment and other information available. The costs for service of process will depend on how difficult it is to locate and serve the debtor, but service of process costs range between $50 to $100 for an easy serve. Accordingly, the total cost including court filing fee, service of process expenses and attorney’s fees shouldn’t be more than $1,000 to authenticate a sister state money judgment as a California Judgment. Additional fees and costs will apply if a motion to vacate is filed and for enforcing the judgment. This judgment authentication process usually takes between 45 to 75 days, which includes the 30-day enforcement hold.
