What if a defendant avoids service?

Defendants who duck service are a process server’s daily reality. Family-law respondents, debt-collection defendants, eviction targets — many actively avoid. The law gives plaintiffs a graduated toolkit; you just need to use it correctly.

Short answer

You don’t need the defendant’s cooperation to complete service. The escalation ladder runs: more attempts at different times → substituted service (CCP §415.20) → skip-trace if address is wrong → posting (CCP §415.45 for unlawful detainer) → service by publication (CCP §415.50) as last resort.

When it matters

• Default judgment requires VALID service, not voluntary acceptance
• Statute of limitations doesn’t pause while the defendant hides
• CCP §583.210 gives you 3 years from filing to complete service in CA — plenty of runway but don’t waste it

Step 1 — Vary the attempt pattern

Most evasion is solved by changing when you knock. CCP §415.20 diligence requires "different times of day." Common winning patterns:

• Morning (7-9 AM) before they leave for work
• Lunch (12-1 PM) if they work from home
• Evening (6-8 PM) when they get back
• Saturday morning (8-10 AM) when they’re less guarded
• Sunday afternoon (1-4 PM) family time

Three attempts at varied times is the legal floor; in our experience 70% of defendants are served by attempt 4.

Step 2 — Substituted service

If varied attempts fail (defendant is genuinely never home or refusing to answer), CCP §415.20 substituted service kicks in: leave with a competent 18+ adult at the dwelling + mail a copy. See [California substitute service](/guides/california-substitute-service) for the full rule.

This is the resolution for most evasion cases. Service is deemed complete 10 days after mailing.

Step 3 — Skip-trace

If the defendant has moved or the address turned out wrong, you need a current address before any more attempts. Skip-trace pulls from utility records, voter registration, employment data, and public databases to surface a likely current address. Servd’s skip-trace add-on is $40 and includes:

• Last-known utility address
• Last-known employer
• Last-known vehicle registration
• Likely current residence with confidence score

Once the new address is identified, the attempt cycle restarts there.

Step 4 — Posting (unlawful detainer only)

For eviction (UD) cases specifically, CCP §415.45 allows posting — the server tapes a copy of the notice to a conspicuous place on the property + mails a copy — after a court order authorizing the method. Posting requires you to show the court that personal and substituted service have been attempted with due diligence.

Posting does not apply to civil summonses outside the UD context.

Step 5 — Service by publication (last resort)

CCP §415.50 allows service by publication in a newspaper of general circulation. Requirements:

• Court order on a motion showing exhausted diligence
• Skip-trace results showing no current address
• Publication in a court-approved newspaper for 4 consecutive weeks
• Mailing to the defendant’s last known address

Publication costs $200-800 depending on newspaper and runs about 30 days. Most courts require you to demonstrate substituted service was impossible before granting publication. Used in <3% of our cases.

Common mistakes

• Going to substituted service after 2 attempts. CA courts have held two is rarely enough; insist on three.
• Skipping skip-trace and jumping to publication. Court will deny the motion if a current address could have been found cheaply.
• Posting on a civil summons (non-UD). §415.45 is unlawful-detainer-only; posting on a civil case voids the service.
• Publication in the wrong paper. The court order specifies which newspaper; using a different one invalidates service.

What Servd does

AI tracks attempt cadence and surfaces sub-service when diligence is met. If diligence-met but defendant still evasive, we suggest skip-trace and quote $40. We do publication coordination (court motion, newspaper booking, mailing) on request.
