Military Service Affidavit / Affidavit of Non-Military Service: A Complete Guide
What it is, when you need it, what goes in it, and how to obtain the official DoD certificate that backs it up — even without a DOB or SSN.
What is a Military Service Affidavit?
A Military Service Affidavit is a sworn statement filed with a court that attests whether a person (usually a defendant) is currently in military service. Because it’s most often used to show the person is not on active duty, it’s frequently called an Affidavit of Non-Military Service. It exists to satisfy the Servicemembers Civil Relief Act (SCRA), which protects active-duty servicemembers from default judgments. Learn more in our SCRA overview.
When do courts require one?
You’ll typically need a military service affidavit before a court will enter a default judgment in matters such as:
- Small-claims and civil money judgments
- Debt collection actions
- Evictions
- Foreclosures
- Certain family-law matters, like divorce when one party doesn’t respond
Requirements and forms vary by state and even by county, but the underlying need is the same: proof of the person’s military status.
What must the affidavit include?
While formats differ, a military service affidavit generally includes:
- The identity of the person whose status is being attested
- A statement of whether that person is or isn’t in military service
- The factual basis for the statement — typically the DoD active-duty status certificate
- The affiant’s signature, often notarized
Courts want the statement backed by evidence, not guesswork — which is why the DoD certificate matters.
How to get the certificate behind the affidavit
The supporting evidence is the U.S. Department of Defense (DoD) active-duty status certificate, produced through the Defense Manpower Data Center (DMDC). You can obtain it free at scra.dmdc.osd.mil if you have the person’s Social Security number or date of birth. Active-duty data is available from September 30, 1985 to the present.
What if you don’t have the SSN or date of birth?
This is the most common obstacle. Our licensed private investigator locates the missing identifier for a permissible purpose, runs the official check, and emails you the certificate. See how it works or start a search.
Tips for filing
- Check your specific court’s form and notarization requirements.
- Make sure the certificate matches the correct person — confirm identifying details.
- Note the date of the search; courts care about status as of a relevant date.
- Never attest to something you don’t have evidence for — false affidavits carry penalties.
