Texas is a personal service state, which means a citation and petition have to reach a named person directly before a case can move forward. When a process server makes multiple attempts at a residence or business and still comes up without a direct personal service, the file either moves to substitute service under Rule 106(b) of the Texas Rules of Civil Procedure, or it stalls. The rule sounds simple on paper. In practice, the four attempts get all the attention, and the actual requirement sitting underneath them gets missed, which is exactly what got a young process server named Ricky pulled into his supervisor’s office.
“Four attempts, no answer,” Jimmy told his young process server, Ricky. “That’s due diligence. That’s not a 106(b).”
Ricky frowned. “But I made four attempts. Nobody answered.”
“I’ve told you this three times now,” Jimmy said. “Due diligence just means you showed up and tried. A judge doesn’t care how many times you knocked if nobody ever confirmed the guy actually lives there. Someone at that residence has to look you in the eye, at least once out of your four attempts, and tell you the recipient lives there. That’s the whole rule. Without it, you don’t have a 106(b) request, you have four wasted trips.”
Ricky still looked unconvinced, so Jimmy laid out the whole case. “Last month I had a defendant like that. First attempt, nothing. Second attempt, nothing. Third attempt, an old woman answers the door, arms crossed, tells me, ‘He’ll be home in two days. Now get off my porch,’ and shuts the door in my face. Fourth attempt, two days later, still nothing. Four attempts total, Ricky, and one of them, just one, gave me a resident confirming out loud that the defendant lives there. That’s what let me file the Texas Non-Service Affidavit in Support of Substitute Service under Rule 106. Not the four wasted trips on their own. The confirmation is what carries the motion.”
How Does Rule 106 Substitute Service Work? (The Short Version)
Rule 106(b) is what a Texas court uses when standard personal service, handing the citation and petition directly to the defendant, hasn’t worked. It lets an attorney ask a judge to authorize an alternative method, usually posting the documents at the defendant’s address and mailing a copy by certified mail.
It’s not automatic. A judge has to sign off first, based on a sworn statement showing genuine attempts were made and the address is actually correct. Skip that step, and any posting or mailing you do on your own carries no legal weight.
Step 1: Document Four Failed Attempts
Texas doesn’t set a fixed number in the rule itself, but courts generally expect to see a documented pattern before granting a Rule 106(b) motion, and in practice that means a minimum of four attempts, spread across different days and times of day, including a weekend.
One note on business defendants before you start: not every business situation needs Rule 106 at all. If the registered agent on file isn’t the owner, and that person or an authorized employee accepts documents normally, that’s just standard business service. Rule 106 comes into play specifically when the registered agent is the owner themselves and that person is the one avoiding you.
Here’s the rookie mistake: treating avoidance as proof. A process server who sees someone bolt for the door, slam it, and cut the lights has documented exactly one thing, that person didn’t want to be seen. It doesn’t confirm who that person was. It doesn’t confirm they live there. A judge reading that account has no way to verify anything beyond “somebody appears to be avoiding contact.” That’s not enough on its own.
What actually counts:
• A resident, someone 16 or older who lives at the address, confirms the defendant lives there too, even indirectly, “she’s truck driving, back end of the week” counts just as much as a direct yes
• A neighbor confirms the defendant’s residency, usually checked after the first attempt comes up empty
• A named employee confirms the defendant works there and explains why they’re unavailable
- A positive visual identification, if you have a photo of the defendant, see them clearly through a window, and they ignore the door, that’s different from an ambiguous glimpse and generally supports a Rule 106 request
• Attempts spread across different days and times, not four visits at the same hour
What kills the address entirely, not just the attempt:
• “We don’t know this person,” or “this is a different business”
• “They got fired, no longer works here”
• “We’re renting this place, never heard of them”
Answers like those don’t support a Rule 106 motion, they tell you the address is wrong. That’s a skip trace problem, not a substitute service problem.
A few more things worth knowing. Confirmation doesn’t shortcut the count, if a resident confirms residency on attempt one, you still need three more attempts before filing. And if a property is gated or otherwise inaccessible, four unsuccessful attempts at getting past that gate still count toward your four, not being able to physically reach the door doesn’t mean the person doesn’t live there, it just means the attempts were unsuccessful for a different reason.
Step 2: File the Sworn Statement and Motion
Since Rule 106 was amended at the end of 2020, the supporting document is no longer technically called an affidavit. It can be a statement sworn before a notary or signed under penalty of perjury.
The statement has to include:
• The specific address where the defendant can probably be found
• The dates, times, and outcomes of each attempt
• The fact confirming residency, and who provided it
The motion and the sworn statement are two separate documents, filed together. The motion asks the court to authorize an alternative method. The statement is what backs it up.
Step 3: Wait on the Judge’s Ruling
There’s no statutory deadline requiring a ruling by a specific date. Turnaround depends entirely on the court’s docket. Some judges sign an uncontested motion the same day. Others take a few weeks if the civil docket is backed up.
Since the defendant isn’t part of this motion and doesn’t get notice of it, there’s usually nobody opposing it, which keeps most Rule 106(b) requests on the faster end.
Step 4: Comply With the Order
Once granted, the order tells you exactly what to do next, and it takes more paperwork than people expect. You need printed copies of three separate documents: the order, the citation, and the petition. The order by itself carries no weight without the underlying documents attached.
Standard compliance looks like this:
• Post copies of the citation and petition at the address, photographed as proof
• Mail a separate set by certified mail, return receipt requested, to the same address
• Confirm whoever receives the posted copy, if anyone answers, is at least 16
One thing worth knowing: if the defendant actually answers the door on this visit, you don’t need the order at all. Personal service still wins whenever it’s available. Serve them directly and skip the rest.
Rule 106 vs. Other States: Why Texas Won’t Let You Skip the Judge
This is where Texas genuinely differs from states attorneys may be used to. In several states, once a third party confirms the defendant lives there, a process server can substitute serve that person on the spot, no judge, no waiting period.
Texas doesn’t work that way. Confirmation from a resident gets you the right to ask a judge. It doesn’t authorize anything by itself. The order has to be signed first. If you’ve handled substitute service somewhere else, don’t assume Texas moves at the same speed.
The Certified Mail Problem
This is the part that has nothing to do with legal strategy. Certified mail with return receipt requested means an actual paper card has to travel to the address, get signed, and travel back to you before you have physical proof the mailing happened. In theory, that’s a week or two. In practice, tracking numbers stall at “in transit,” cards get delivered to the wrong door, and the whole thing can disappear for weeks with no explanation.
Here’s the good news buried in the bad news: many standard Texas county order templates, Dallas, Tarrant, Harris, and Denton among them, state that service is deemed complete once you’ve complied with the order, regardless of whether the defendant ever signs the card. The mailing itself, done correctly, is often what satisfies the order. The card coming back is just extra proof, not a requirement.
One Month, No Green Card, What Now
• Wait the full 30 days. USPS won’t accept a trace request before then.
• Pull the tracking history. A delivery scan without a signature still shows the mailing reached the address, and that’s useful backup documentation.
• Check your specific order’s language. Not every county’s template says the same thing. A small number still expect the signed card before treating service as complete.
• If tracking shows the item was never delivered, not just delayed, send it again. A return of service built on an undelivered mailing is easy to challenge later.
Common Mistakes That Kill a Rule 106 Motion
• Treating avoidance as verification. Someone hiding isn’t the same as someone confirmed.
• Skipping the neighbor check. It’s a free second path to confirming residency, and courts like seeing it.
• Filing without four documented attempts. Fewer than that, and you’re inviting a denial.
• Posting without mailing, or mailing without posting. Both parts of the order have to be completed before you file the return.
• Assuming Texas works like the last state you filed in. It doesn’t. Get the order first.

Bottom Line
Rule 106(b) rewards documentation, not instinct. A person confirming residency is worth more than four attempts of someone avoiding the door. Once you have that, the rest of the process is procedural: file the motion, wait on the order, comply with posting and mailing, and don’t panic if the green card takes its time.
For firms handling multiple substitute service cases across Texas, Ranworks coordinates the attempts, the paperwork, and the mailing together, so a missing green card doesn’t become one more thing your office has to chase down alone.
