Service Affidavit - Wisconsin
DECLARATION OF SERVICE
Important Use Note
This is a customizable proof-of-service worksheet. It is not a mandatory statewide form and does not select a legally valid service method.
The Wisconsin Court System currently publishes FA-4120V, Declaration of Service, as a voluntary form for marriage and paternity matters. That official form states that it may not be modified, although it may be supplemented. Use the current official form when it fits the case. Other proceedings may have different mandatory or voluntary forms.

8. Small-Claims and eFiling Limits
General Civil Timing
For a general civil action seeking a personal judgment, Wis. Stat. § 801.02(1) provides that the action is commenced as to a defendant when the summons and complaint naming that defendant are filed, provided authenticated copies are served under Chapter 801 within 90 days after filing. A different statute, rule, or order may control another kind of action or paper.
Filing date: [__/__/____]
Case-specific service deadline confirmed from current authority: [__/__/____]
Authority used to calculate deadline: [________________________________]
Small Claims
Wis. Stat. § 799.12 generally applies the Chapter 801 service rules to small claims but permits a circuit court, by rule, to authorize clerk mail service. Under that authorized mail procedure, the filer submits the summons, mail-service request, and prescribed fee, and the clerk mails the summons. Do not use this declaration as a substitute for the clerk's mail-service record or assume every county authorizes the same procedure.
Small-claims local rule or clerk instruction checked: ☐ Yes ☐ Not applicable
Source checked: [________________________________]
Electronic Filing
Under Wis. Stat. § 801.18(5)(d), initiating documents are served by traditional methods unless the responding party has consented in writing to electronic or another method. Under § 801.18(4)(c) and (6)(a), when personal service is not required, the electronic filing system's notice of activity can constitute proof of service on other users in the case.
☐ This declaration concerns initiating documents served by an authorized method.
☐ This declaration concerns a document for which separate proof is required despite eFiling.
☐ The eFiling notice of activity is the applicable proof; this separate declaration is not being used as a substitute.
9. Declaration and Signature
Wis. Stat. § 887.015 generally gives a compliant unsworn declaration the same effect as a sworn declaration when Wisconsin law requires or permits a sworn declaration, subject to the statute's exceptions. Its required form includes the declaration, date, location, printed name, and signature below.
I declare under penalty of false swearing under the law of Wisconsin that the foregoing is true and correct.
Signed on the [____] day of [________________________________], [________], at [City or other location] [________________________________], [State or country] [________________________________].
Printed name: [________________________________]
Signature: [________________________________]

These are the filings that drive a lawsuit through the system: complaints, answers, motions, briefs, discovery requests and responses, and post-judgment papers. Each has its own format requirements under federal and state procedural rules, and each has a deadline that cannot be missed without consequences. Clean, procedurally correct filings move a case forward; sloppy ones invite motions to strike, amended responses, and avoidable delays.
