The 4-Step Coos County Records Pathway
1
Step 1 — Start at the Coos County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Coos County clerk's office is the first stop.
2
Step 2 — Use the New Hampshire statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the New Hampshire state level — not by the county.
3
Step 3 — Federal sources for federal records
Federal court cases (PACER), federal tax liens (IRS), military records (NPRC), and immigration data (ICE) are all federal — not held by the county.
4
Step 4 — Cross-check before relying on data
Most county portals lag 24-48 hours behind the courthouse. For time-sensitive verification, call the clerk directly.
Five Things People Get Wrong About Coos County Records
MYTH"Coos County maintains all criminal records."
FACTCriminal records for Coos County are held by the New Hampshire state repository, NOT the county. The county sheriff has only the local arrest log.
MYTH"Records sealed in Coos County are gone everywhere."
FACTSealing removes records from public search but they still exist at the courthouse and may appear in FBI records (Identity History Summary).
MYTH"Free 'instant background' sites have Coos County data."
FACTOnly the official New Hampshire state repository has verified, current Coos County data. Free sites often have stale data.
MYTH"The Coos County assessor's value is what I'll sell my home for."
FACTThe Coos County assessor's value is for property tax purposes only — usually below market value.
MYTH"All county records older than 50 years are public."
FACTPartially false. Public-records rules vary by record type AND state. Court records and deeds are usually older-public; vital records remain restricted longer (often 75-125 years).

Frequently Asked Questions
How do I look up court cases in Coos County?
Coos County court cases are filed with the Clerk of Court. Search the New Hampshire Judicial Branch portal: https://www.courts.nh.gov/. For federal matters, see PACER.
Are New Hampshire marriage records public?
Marriage records in New Hampshire are generally public — anyone can verify that a marriage occurred and request a non-certified copy. Certified copies (needed for legal purposes like name changes or immigration) may be restricted to the spouses, immediate family, or those with a court order.
Can I find out if someone is divorced in New Hampshire?
Yes. Search the court case index for the person's name in the county where they lived. Most New Hampshire counties offer free online case-search portals. The state vital records office also issues divorce verifications for a fee.
Does a county sheriff have to honor ICE detainers?
No federal law forces a county to honor an ICE detainer. Multiple federal courts have ruled that detainers are non-binding requests. Some counties honor every detainer, others honor none, and many honor them only when ICE provides a judicial warrant. Policy is set at the county or sheriff level.
