Mississippi Proof of Service
Mississippi lets any non-party adult at least 18 serve a summons, but Form 1A requires that server's proof to be a notarized affidavit, not an unsworn declaration, while a sheriff's return needs no notarization at all.

Introduction
In Mississippi, a summons may be served by the county sheriff, on written request, or by any non-party at least 18 (Rule 4(c)(1)-(2)). A party cannot serve their own summons. The proof of service is printed on the reverse of the summons itself, Form 1A for a process server or Form 1AA for a sheriff, and the court's own version controls if one is required. A sheriff's return needs no oath. Anyone else must make a notarized affidavit (Rule 4(f)); no Mississippi statute letting an unsworn declaration replace that affidavit was confirmed. Personal delivery is one method. If it cannot be made with reasonable diligence, the server may leave copies at the defendant's abode with a spouse or family member older than 16, then mail a copy first-class; service is complete on the 10th day after mailing. First-class mail alone is not valid unless paired with the Form 1B notice-and-acknowledgment and a prepaid return envelope, and if no acknowledgment returns within 20 days, another method is required. Certified mail works only for a defendant outside Mississippi. Service must happen within 120 days of filing, or the case can be dismissed without prejudice absent good cause. There is no fixed deadline to file the proof beyond promptly, though a sheriff must return the summons within 30 days. Later papers are proven with a certificate of service under Rule 5, not the Form 1A affidavit. Federal, out-of-country, and government service follow separate rules not covered here. Because the proof is sworn, never misstate how service occurred. Attorney review is available before you file.
Key Things to Know
- 1
A summons and complaint may be served by the sheriff of the county where the defendant resides or is found, acting on a written request, or by any person who is not a party and is at least 18 years old (Rule 4(c)(1)-(2)); a party cannot serve their own summons. Mississippi's proof of service is not a separate form: it is printed on the reverse of the summons itself, Form 1A for a process server or Form 1AA for a sheriff, and the court's own version controls if one is required.
- 2
Ordinary mail alone does not serve a summons. First-class mail service requires two copies of the Form 1B notice-and-acknowledgment and a prepaid return envelope; if no acknowledgment is returned within 20 days, service must be attempted by another method. Certified mail, return receipt requested (restricted delivery if a natural person), is a separate valid method but only for a defendant outside Mississippi, complete on the date of delivery shown on the receipt or a 'Refused' envelope.
- 3
There is no fixed day count to file the proof of service; Rule 4(f) requires only that the server make it promptly, and failure to file proof does not affect the validity of service itself. A sheriff, by contrast, must mark the receipt date and return the summons to the clerk within 30 days of receiving it.
- 4
A sheriff's return needs no oath or notarization. Anyone else who serves the summons must make a notarized affidavit of service under Rule 4(f); no Mississippi statute was confirmed that lets an unsworn declaration under penalty of perjury substitute for that notarized affidavit.
- 5
If personal service cannot be made with reasonable diligence, the server may leave copies at the defendant's usual place of abode with the defendant's spouse or another family member older than 16 who is willing to accept them, then mail a copy by first-class mail to that address; service is deemed complete on the 10th day after mailing (Rule 4(d)(1)(B)).
- 6
Service must be completed within 120 days after the complaint is filed. If it is not, and the party responsible cannot show good cause, the court can dismiss the action against that defendant without prejudice, on its own initiative or by motion (Rule 4(h)).
- 7
Once a case is underway, later papers such as motions go to the attorney of record unless the court orders service on the party directly, by hand delivery, mail, or electronic transmission. Proof is a certificate signed by the person who served the paper under Rule 5(d), with no numbered official form and no notarization required.

Mississippi Requirements for Proof of Service
Only Certain People May Serve a Mississippi Summons
The sheriff of the county where the defendant resides or is found may serve, acting on a written request, or any person who is not a party and is at least 18 years old may serve (Rule 4(c)(1)-(2)). A party to the case cannot serve their own summons.
Proof of Service Printed on the Summons Itself
Mississippi has no standalone numbered proof-of-service form for initial process; the proof is printed on the reverse of the summons, Form 1A for a process server or Form 1AA for a sheriff. Those forms are mandatory, and the issuing court's own version controls if required.
Notarized Affidavit Required Unless a Sheriff Serves
Anyone other than a sheriff who serves the summons must make a notarized affidavit of service (Rule 4(f)); no Mississippi statute was confirmed that lets an unsworn declaration under penalty of perjury substitute for that affidavit. A sheriff's return needs no oath or notarization.
Ordinary Mail Alone Does Not Serve a Summons
First-class mail service requires two copies of the Form 1B notice-and-acknowledgment and a prepaid return envelope; if no acknowledgment returns within 20 days, service must be attempted another way. Certified mail, return receipt requested (restricted delivery if a natural person), is a separate method but only for a defendant outside Mississippi.
Residence Service Requires Reasonable Diligence First
If personal service cannot be made with reasonable diligence, the server may leave copies at the defendant's usual place of abode with the defendant's spouse or another family member older than 16, then mail a copy first-class to that address. Service is deemed complete on the 10th day after mailing (Rule 4(d)(1)(B)).
120-Day Deadline to Serve the Summons
Service must be completed within 120 days after the complaint is filed, or the court can dismiss the action against that defendant without prejudice absent a showing of good cause, on its own initiative or by motion (Rule 4(h)).
No Fixed Deadline to File the Proof
Rule 4(f) requires only that proof of service be made promptly, with no fixed day count, and failure to file it does not affect the validity of service itself. A sheriff must still return the summons to the clerk within 30 days of receiving it.
Certificate of Service for Later Papers
Later papers such as motions are proven with a certificate signed by the person who served the paper under Rule 5(d), not the Form 1A affidavit, with no numbered official form and no notarization required.
