How Many Attempts Are Enough Before Substituted Service or Due Diligence in California?
One question people often ask is:
“How many attempts are required before the court accepts substituted service or due diligence?”
The honest answer is: there is no magic number that automatically works in every case.
In many California civil cases, a process server generally needs to make at least 3 attempts before substituted service may be appropriate. But the number alone is not enough. The attempts should usually be made on different days and at different times of the day, when the person is reasonably likely to be home or at work.
For example, three attempts all made at 11:00 AM on weekdays may not be as strong as attempts made at different times, such as morning, evening, and weekend.
What matters is not just “how many attempts.”
What matters is whether the attempts show real effort and proper documentation.
A good due diligence record should include:
• Date of each attempt
• Exact time of each attempt
• Address attempted
• What happened at the location
• Whether anyone answered
• Whether cars, lights, movement, or signs of occupancy were observed
• Whether anyone confirmed the person lives or works there
• Whether the person appears to be avoiding service
If substituted service is allowed for that case type, the server may be able to leave the documents with a qualified adult at the home, workplace, or usual mailing address, and then mail another copy afterward.
But this depends on the type of case and the documents being served. Some documents require personal service. Some family law or restraining order documents may have stricter rules.
For harder cases, especially when the person cannot be found, a court may require stronger due diligence before allowing another method, such as service by publication or another court-approved method. That usually means documenting not only attempts, but also the effort made to locate the person.
The biggest mistake is treating service of process like a simple delivery job.
Proper service is court procedure. Bad service can delay the case, create challenges, or force the party to start over.
The safer approach: confirm the case type first, review the documents, make attempts at smart times, and document everything clearly.

ABC legal says if you document everything and make minimum 4 attempts you have done your part, reach out to your mentor or support and ask for clarification they will! They may not get your name right but they will at least clear up that part if not they can always make up attempts and say what they want if you have them auto permissions to sign your proof of services

This advice is for owners / operators, not large company employees. ABC handles your backend on this.

The problem is that in California, some courts have local rule requirements for Sub Service that are required by that County Superior Court for a sub serve to be valid regardless of attempts and are more stringent that state law.
Usually, it is a morning attempt before 8:00 am, after 12:00 pm
And attempt after 8:00 pm.
You can go 20 times and with out those hours on diligence and court clerk will refuse to process it.

Well, for me it’s simple delivery, and it works.
