Dockets, filings, and court records
Certificate of Service
A certificate of service is the short statement at the end of a filing swearing that a copy was sent to every other party and saying how.
In an electronically filed case most service happens automatically through CM/ECF, so the certificate says that. It still matters for parties who are not on the system, such as a pro se litigant receiving paper by mail, and for documents served before an appearance is filed.
It looks like boilerplate and occasionally decides motions. If a party claims it never received something, the certificate of service is the first document the court looks at.
It also creates the paper trail for calculating deadlines. Response times often run from the date of service rather than the date of filing, so when the two differ, the certificate is what tells you which clock is running.
How it appears on a docket
