How Many Attempts Are Considered Reasonable?
There's no magic number.
"Reasonable efforts" depend on timing, access, geography, behavior, and the type of case. But courts expect one thing every time:
Good-faith attempts made at different times, on different days, documented clearly.
In Arizona and most jurisdictions, courts do not set a fixed number of required attempts. The standard is professional judgment supported by defensible documentation.
The Industry Standard: 3–5 Attempts With Varied Timing
Professional process servers follow a three-part structure:
Morning Attempt
To catch commuters, shift workers, school routines, early risers.
Evening Attempt
To catch after-work returns, family routines, apartment traffic peaks.
Weekend Attempt
To catch off-duty schedules, irregular routines, hard-to-pin subjects.
This triad is widely accepted as the foundation of "reasonable diligence."
Additional attempts may be added based on:
Courts view this as evidence of good-faith effort—not guesswork.
"Reasonable" Depends on the Situation
The number of attempts needed shifts based on context.
Gated Communities & Callboxes
Reasonable = adjusting for access barriers.
Apartments with Controlled Entry
Reasonable = matching the building's rhythm.
Evasive or High-Avoidance Behavior
Reasonable = demonstrating persistence and documentation.
Rural or Remote Properties
Reasonable = context-sensitive effort.
Workplace Service
Reasonable = choosing the environment with higher success probability.
What Courts Actually Look For
Courts don't count attempts—they evaluate effort, timing, and documentation. Judges look for:
- Attempts on different days
- Attempts at different times
- Notes proving occupancy indicators
- Documentation of barriers
- Evidence the subject is intentionally avoiding
- Good-faith effort before requesting alternative service
If these elements are present, courts almost always deem the efforts reasonable—even if the number is low.
If these elements are missing, courts reject service—even if five attempts were made.
Reasonable = diligence + documentation.
When Alternative Service Becomes Justified
Alternative service (posting & mailing, workplace agent, email, etc.) becomes justified when:
Most Arizona judges approve alternative service after 3–5 well-documented attempts with varied timing.
When One Attempt Is Enough
One attempt may be reasonable when:
The defendant is served successfully
No need for more attempts.
Workplace service succeeds first try
Workplace attempts are valid personal service.
The subject refuses service at the door
Once identity is confirmed and refusal protocol occurs, service is complete.
Court explicitly orders a method
Some orders specify exactly how service must occur.
Reasonable = success.
When More Than Five Attempts Make Sense
Heavily evasive or high-stakes cases may require extended effort:
Here, "reasonable" may expand to:
- 6–10 attempts across multiple locations
- Stakeout windows at critical times
- Integration of workplace and public-area attempts
Reasonable = matching the subject's evasion tactics.
Real-World Scenarios of "Reasonable Attempts"
Suburban Home
Reasonable? Yes.
Apartment With No Callbox Listing
Reasonable? Yes, with documented access issues.
Worksite Avoidance
Reasonable? Yes—service complete.
Evasive Subject With Cameras
Reasonable? Yes—supports alternative service motion.
Rural Property
Reasonable? Yes—context matters.
Why "Reasonable Attempts" Are About Strategy, Not Counting
People often ask: "How many times do you try before giving up?"
But the real question is:
"Have you made meaningful attempts at reasonable times with clear documentation that supports the next legal step?"
Courts don't want volume—they want legitimacy.
Reasonable = professional judgment, not repetition.
Bottom Line
Reasonable attempts typically mean 3–5 attempts at different times on different days, documented carefully—unless circumstances justify fewer or more.
Reasonable depends on:
With professional documentation and timing intelligence, courts almost always accept the effort—even when service is difficult.
