Who Can Legally Serve Papers in Arizona
Certified Arizona Process Servers
Licensed professionals who pass state certification, undergo background checks, and follow strict procedural rules.
- Summons & Complaints
- Divorce and custody documents
- Evictions (FED)
- Garnishments
- Writs
- Small claims summons
- Corporate agents
- Evasive or high-risk subjects
- Court-ordered alternate service
Certified servers are the gold standard for Arizona service of process.
Sheriffs & Constables
Statutory authority for specific enforcement actions.
- Writs of restitution
- Forcible entry and detainer enforcement
- Certain types of civil process
- High-risk environments
- Post-judgment execution actions
Typically used for eviction enforcement and writs involving possession.
Any Adult (over 18) Who Is Not a Party
Applies primarily to basic civil matters where no certification is required.
- Must be over 18
- Cannot be named in the case
- Must follow service rules
- Must complete a valid proof of service
Just because "any adult can serve" doesn't mean they should—or that it's easy.
Court-Appointed Special Process Servers
In rare cases, the court may authorize a specific individual for a single case.
- Remote locations
- Special circumstances
- Certified server not available
- One-time appointment needed
Uncommon but available when required.

If you are the one bringing the case, you cannot serve the defendant.
- Divorce petitioners
- Eviction filers
- Small claims plaintiffs
- Civil lawsuit plaintiffs
- Family court petitioners
Courts require a neutral third party.
Anyone Under 18
No exceptions—even if they know the defendant, are willing, or the case seems simple.
No exceptions.
Anyone With a Conflict of Interest
Bias invalidates service.
- A friend who will testify in the case
- A tenant serving a landlord (or vice versa)
- Someone financially tied to the dispute
Bias = invalid service.
Anyone Attempting Service Illegally
Illegal methods void the service.
- Trespassing
- Entering locked areas without permission
- Deception ("fake delivery" tactics)
- Threatening or coercive behavior
Illegal service = invalid service.
