When legal action needs to move forward, selecting the right method for serving legal papers is critical. A wrong move could result in delays, dismissed cases, or legal challenges. But the right strategy ensures documents are delivered fast, legally, and without complications.
So, how do you pick the best method for the service of process? That depends on the type of case, urgency, and whether the recipient is cooperative or evasive.
1. Personal Service – The Gold Standard
Personal service is the most effective and legally secure way to serve documents. A process server physically hands the papers to the recipient.
Best For:
Lawsuits (civil cases, debt collection, contract disputes)
Subpoenas (witness testimony, document requests)
Restraining orders (ensuring defendants are properly notified)
Divorce or custody papers (family court matters)
Why It’s the Best Method:
Immediate proof of service – The process server can confirm delivery.
Legally airtight – Harder for the recipient to challenge in court.
Eliminates delays – No waiting for mail or alternative service approvals.
Whenever possible, opt for personal service—it’s the fastest and most foolproof option.
2. Substituted Service – When Personal Service Fails
If the recipient can’t be served directly, process servers can leave the papers with another responsible adult.
Best For:
Evictions & rental disputes (tenants dodging service)
Defendants who travel frequently (spouses, business owners)
Cases where the recipient refuses to answer the door
Key Requirements:
Papers must be left with someone 14 years or older who lives at the same residence.
The process server must mail a second copy of the papers to confirm service.
This method is only valid if personal service was attempted first.
Substituted service is a strong backup option when direct delivery isn’t possible.
3. Posting & Mailing – For Evictions & Landlord Cases
For eviction notices, Arizona law allows service by posting and mailing. This means taping the notice to the property and sending a copy via mail.
Best For:
Evictions (when a tenant won’t answer the door)
Foreclosures (legal notices to property owners)
Landlord-tenant disputes (court-ordered removal notices)
Key Requirements:
The process server must attempt personal service first.
Papers must be posted in a visible location (e.g., the front door).
A certified mail copy must be sent to the tenant.
This method ensures tenants are legally notified—even if they refuse to cooperate.
4. Certified Mail – For Cooperative Recipients
Some legal papers can be sent by certified mail—but the recipient must sign for them.
Best For:
Cooperative defendants (who are expecting the papers)
Business-related legal matters (contracts, agreements, formal disputes)
Cases where physical service is difficult or unnecessary
Key Requirements:
The recipient must personally sign for the document.
If someone else signs, service may not be legally valid.
A signed return receipt is required for proof of service.
Certified mail is only reliable if the recipient willingly accepts it.
5. Service by Publication – When the Defendant Has Disappeared
If someone is completely missing, a judge may allow service by publication—publishing a legal notice in a newspaper.
Best For:
Divorces & child custody cases (when the other party is missing)
Defendants who have moved and left no forwarding address
Cases where all other service attempts have failed
Key Requirements:
The court must approve alternative service before publication.
Plaintiff must show proof of diligent efforts to locate the defendant.
The legal notice must be published in a newspaper for a set time period.
This is a last-resort option—but it ensures the case moves forward.
6. Workplace Service – Catching the Recipient Off Guard
If the recipient avoids service at home, process servers can serve them at work.
Best For:
Defendants who never answer the door
People who travel frequently but have a known job location
Cases where personal service is needed but home delivery fails
Key Considerations:
Some workplaces restrict serving employees on-site.
If entry is restricted, the server may need to wait outside.
Public areas like parking lots can be used for workplace serves.
This method is highly effective for dodging defendants—but must be handled carefully.
7. Law Enforcement or Sheriff Service – When Required
In some cases, law enforcement officers can serve legal papers—but it’s usually slower than hiring a process server.
Best For:
Criminal-related cases (court orders, subpoenas for law enforcement matters)
Defendants with a history of violence (added security needed)
Court-mandated sheriff service (if required by law)
Key Downsides:
Law enforcement is often too busy to prioritize process serving.
Sheriff’s service may take weeks compared to private process servers.
More expensive than standard process service in some cases.
When speed matters, private process servers are the better choice.
Final Takeaway: Choose the Best Method Based on Speed, Legality & Efficiency
Not all service methods are equal—the best one depends on your case and how cooperative the recipient is.
Best Methods by Situation:
Fastest & most reliable: Personal service by a process server.
Best for evasive defendants: Stakeouts, workplace service, skip tracing.
Only used in extreme cases: Service by publication.
For evictions & landlord cases: Posting & mailing.
Best for cooperative recipients: Certified mail.
