Oakland County, Michigan Business Search: What to Know
Two searches cover the basic questions about an Oakland County business's public record. The State of Michigan's business entity search shows whether a corporation or LLC is active, when it was formed and its resident agent. The Oakland County Clerk keeps assumed name records for sole proprietors and partnerships doing business under another name. A partner reading a request may run both.
How to File a DBA in Oakland County, Michigan
A sole proprietor or partnership using a name other than the owners' own names files an assumed name certificate with the clerk of the county where the business operates. Corporations and LLCs file assumed names with the state instead. Keep the filed certificate with the business's bank records, because a partner may compare the name on the account with the name on file.
Requests From Just Across the Oakland County, MI Line
A business just across the county line can still send a request. This site's county figures describe Oakland County only, so they do not describe towns in Macomb, Wayne or Genesee counties. The industry pages and the financing options page apply wherever the business is.
