Why Connecticut's 'Return of Process' Rules Are Unique

In Connecticut state court practice, the phrase 'Return of Service' has two distinct meanings that every litigator and paralegal must track carefully:

1. The Proof / Affidavit of Service (Officer's or Indifferent Person's Return): The sworn written statement endorsed on or attached to the original writ, subpoena, or notice attesting to the exact date, time, place, and manner of service.

2. Returning the Process to Court (C.G.S. § 52-46a): Physically or electronically filing the served writ, summons, complaint, and attached Return of Service with the clerk of the Superior Court prior to the Return Day.

The Mandatory 12-Day & 6-Day Calendar Deadlines (C.G.S. § 52-46 & § 52-46a)

For standard Superior Court civil and family actions, two statutory deadlines govern service and return:

• Service At Least 12 Days Before Return Day (C.G.S. § 52-46): Civil process returnable to the Superior Court must be served at least 12 days, inclusive, before the Tuesday Return Day.

• Return to Clerk At Least 6 Days Before Return Day (C.G.S. § 52-46a): Process in civil actions returnable to the Superior Court must be returned to the clerk of the court at least 6 days before the Return Day (meaning no later than the Wednesday immediately preceding the Tuesday Return Day).

What happens if a writ is returned 5 days before the Return Day instead of 6? Under Connecticut Supreme Court precedent (*Coppola v. Coppola*), late return of process renders the action voidable upon a timely Motion to Dismiss unless the plaintiff amends the Return Day under C.G.S. § 52-72!

Notarized Affidavit of Service for Indifferent Persons vs. Officer's Return

While a commissioned State Marshal signs an Officer's Return under their official oath of office (and must itemize all statutory fees and mileage on the return under C.G.S. § 52-261), an Indifferent Person (private process server) serving a Connecticut subpoena (C.G.S. § 52-143), Small Claims writ (Form JD-CV-123), Federal summons, or out-of-state action must sign a sworn Affidavit of Service before a Notary Public or Commissioner of the Superior Court.

Every Affidavit of Service prepared by Connecticut Process Service LLC includes:

• The full caption, court, and docket/case number;

• The exact title of every document served (including any witness fee check amount tendered);

• The date, exact time, and street/unit address of service;

• Whether service was made personally in hand, at the verified usual place of abode, or to a named corporate officer/registered agent intake clerk (with physical description when required); and

• A full Connecticut Notary Public jurat and seal.

Frequently Asked Questions: Return of Service Rules in CT

What is the deadline to return a served Summons and Complaint to the Connecticut Superior Court?

Under C.G.S. § 52-46a, civil process returnable to the Superior Court must be returned (filed with the clerk) at least 6 days before the Tuesday Return Day.

Does an Indifferent Person's Return of Service need to be notarized in Connecticut?

Yes. When process or a subpoena is served by an Indifferent Person rather than a state marshal, the Return / Affidavit of Service must be sworn to and subscribed before a Notary Public or a Commissioner of the Superior Court (an attorney licensed in Connecticut).

Can a defective Return Day be fixed under Connecticut law?

Under C.G.S. § 52-72, Connecticut courts allow a plaintiff to amend a civil process that was returned late or specified an improper Return Day, provided the amended return day remains within the two-month limit of C.G.S. § 52-48.
