Service of process by certified mail
Certified mail can serve a defendant in some courts, is half of a method in others, and is no service at all in the rest. The rules are specific about who may do the mailing, what goes in the envelope, and what has to come back signed. Get one of those wrong and the defendant's first filing is a motion to quash.
Where mail is service
- Texas state court. Rule of Civil Procedure 106(a)(2) allows service by mailing the citation and petition to the defendant by registered or certified mail, return receipt requested. The mailing is done by the clerk, a sheriff or constable, or another person authorized under Rule 103, never by a party, and the receipt has to come back signed by the addressee.
- California, defendant in state. Code of Civil Procedure section 415.30 sends the summons and complaint by first-class mail with two copies of a notice and acknowledgment form and a prepaid return envelope. Service is complete only when the defendant signs and returns the acknowledgment; a defendant who ignores it can be charged the cost of serving another way.
- California, defendant out of state. Section 415.40 allows service by first-class mail requiring a return receipt. Service is complete on the tenth day after mailing, and the signed receipt is the proof.
- Federal court. Rule 4(d) lets the plaintiff mail a request that the defendant waive formal service, with the complaint and a waiver form, by first-class mail or other reliable means. A signed waiver stands in for service; an ignored request does not, and formal service follows.
Many states do not allow mail for the initial summons at all, and most that do reserve it for particular defendants or situations. The rule that governs is the rule of the court where the case is filed, and it is worth reading again each time, because the exceptions are where the motions live.
The return receipt is the return of service
Where certified mail is service, the signed receipt is not a nicety; it is the proof the court requires. The signature has to be the defendant's or someone the rule allows to sign for them, the date on it is the date of service, and a piece that comes back unclaimed or signed by the wrong person has not served anyone. The electronic return receipt delivers that signature and date as a PDF the day the piece is delivered, which is the day the answer clock starts.
What to file afterward
- The return of service, stating who mailed it, when, and how
- The signed return receipt, attached, or in California the signed notice and acknowledgment
- A copy of what was mailed, so the return shows the citation and petition went together
For process servers and litigation staff
A process server running mail service for a dozen firms is running a dozen sets of certified pieces, receipts, and returns, each with its own deadline. With MatterSnail, upload the citation and petition, add the defendant's address, choose Certified Mail with an electronic return receipt, and submit. Each defendant gets their own tracking number and receipt, the mailing keeps the documents, the address, and the mailing date together, and anything submitted before 12:00 p.m. Pacific is handed to USPS the same business day. The return is assembled from records rather than reconstructed from a stack of green cards.
Common questions
Can you serve someone by certified mail?
In some courts. Texas Rule of Civil Procedure 106(a)(2) allows service of the citation and petition by registered or certified mail, return receipt requested. California allows mail with a signed notice and acknowledgment in state (Code of Civil Procedure section 415.30) and first-class mail requiring a return receipt out of state (section 415.40). Federal Rule 4(d) lets you mail a request to waive service, which is not service itself. Many states do not allow mail for the initial summons at all.
Who is allowed to mail service in Texas?
The clerk, a sheriff or constable, or another person authorized under Rule 103, which means someone who is not a party to the case. The return receipt must come back signed by the addressee; a receipt signed by someone else, or a piece returned unclaimed, is not completed service and the return will be attacked.
Is California notice and acknowledgment the same as certified mail service?
No. Under section 415.30 the summons and complaint go by first-class mail with two copies of the acknowledgment form and a prepaid return envelope, and service is complete only when the defendant signs and returns the acknowledgment. Certified mail requiring a return receipt is the method for defendants outside California under section 415.40, where service is complete on the tenth day after mailing.
What proof do I file after serving by mail?
The return of service with the signed return receipt attached, or the signed acknowledgment in California. With MatterSnail each recipient has their own tracking record and electronic return receipt as a PDF, and the mailing keeps the documents, the address, and the mailing date together, so the return is assembled from records rather than reconstructed from memory.
