How to Prove Mail Service in Court
Combine certified tracking, logs, and certificates of service to satisfy court rules.
Published October 26, 2025
Mail service often requires more than a USPS receipt. Judges look for detailed logs, tracking updates, and sworn certificates. CertifiedMailLog and ProofOfService make that package quick to assemble.
When to use this
- You're mailing pleadings, discovery, or notices that require certified or registered mail.
- Opposing counsel disputes whether they received your documents.
- You need supporting exhibits for a motion to deem service complete.
How to do it (fast)
- Log each mailing in CertifiedMailLog with the certified number, recipient, and contents.
- Generate a ProofOfService PDF that references the same mailing details and attach your log as an exhibit.
- Pull tracking updates from USPS and note statuses like delivered or attempted in the log.
- File the log, tracking printouts, and ProofOfService together so the judge sees a complete record.
Why this helps
- Combining logs with sworn certificates leaves little room to dispute service.
- Tracking numbers tied to contents show diligence even if mail is returned.
- Client or court information never leaves your browser.
