Illinois Marriage Certificate Apostille
Illinois marriage certificates for international use must come from the county clerk in the county where the marriage occurred. IDPH does not issue certified copies of marriage records.
Key rule: For apostille, use a county clerk certified marriage certificate. IDPH provides verification only, not certified copies for marriage records.

Common Rejections (And How to Avoid Them)
Verification instead of certified copy
For marriage events, destination authorities usually require a county clerk certified copy, not a statewide verification-only record.
Wrong county source
Order from the county where marriage occurred. Mismatch between issuing county and event details can trigger returns.
Packet gaps
Missing payment totals, request form details, or return shipping instructions are frequent avoidable delays.
Wrong legalization path
Check Hague status first. Non-Hague destinations may require further consular steps after Illinois certification.
