Arizona Affidavit of Service
Understanding the proof of service affidavit required after serving legal papers in Arizona — format, requirements, and filing.
Direct Answer
An affidavit of service in Arizona is a sworn, notarized document completed by the process server after delivery of legal papers. It records the date, time, location, method of service, and identity of the person served. It must be filed with the court to prove service occurred.
Why This Matters
The affidavit of service is the court's only record that service happened. Without a properly completed, filed affidavit, service is legally invisible — the case cannot proceed, default judgments cannot be entered, and the opposing party can challenge service at any time.
What the Affidavit Must Contain
An Arizona affidavit of service must include: the name of the person served, the date and time of service, the location where service was made, the method of service (personal, substitute, etc.), a description of the person served (if individual), the name and signature of the process server, and notarization.
Filing the Affidavit
After service, the affidavit must be filed with the court where the case is pending. The filing creates the official court record that service occurred. Without this filing, the opposing party can argue that service never happened.
Correcting a Deficient Affidavit
If an affidavit is incomplete or contains errors, the court may allow an amended affidavit to be filed — but only if the underlying service itself was valid. An amended affidavit cannot cure a fundamental defect in how service was performed.
Common Mistakes & Edge Cases
Filing an Affidavit Without Notarization
An unnotarized affidavit of service is not legally valid in Arizona courts. Every affidavit must be sworn before a notary public.
Omitting the Description of the Person Served
Courts expect a physical description of the individual served, especially for personal service. Vague affidavits are more vulnerable to challenge.
