About Sweetwater County
Sweetwater County is one of the larger counties in Wyoming by population, which means its courthouse handles a high volume of marriage license applications and divorce filings each year. Higher-volume counties typically offer more flexible request channels — in-person, mail, fax, and increasingly online — and frequently maintain a public-facing case search for civil filings, including divorce indexes.
If you are uncertain whether your event was filed in Sweetwater County rather than a neighboring county, consider both the address listed on the original document (if you have a copy) and where the parties were living at the time of filing. For old marriage licenses in particular, the license was issued in the county where the couple applied — not necessarily where they were married.
If you are out of state and unable to visit the courthouse in person, this remote document-retrieval comparison outlines the trade-offs between mailing a request, using the state's approved online vendor, and hiring an authorized agent.
Tips for working with the county courthouse
- Call before you visit. County clerk and court clerk hours vary, and some windows close earlier than the rest of the courthouse for cash handling.
- Bring exact change or a money order for older records that may not be in the credit-card system.
- For divorces, know the case number if you can — the clerk may charge a per-name search fee on top of the per-page copy fee if a full lookup is required.
- For marriage records older than the county's digital index, expect a longer wait while staff retrieve the physical book.
