Using the Michigan Business Search Correctly
The Michigan Department of Licensing and Regulatory Affairs runs the business entity search at lara.state.mi.us, and it is far less straightforward than most people expect. You can find an entity by name, corporate number, or officer name, but the interface does not warn you about how easily you will miss the record you actually need. I spent about an hour last month trying to confirm whether a client's LLC was still active. The name was "Great Lakes Outdoor Solutions, PLLC." I searched it exactly as written and got zero results. The entity was actually registered as "Great Lakes Outdoors Solution PLLC" — singular "Solution." The search engine stripped the trailing character but also dropped an 's' from "Outdoors." I ended up pulling up the SOS filing manually by the corporate number on the annual report, which listed the exact legal name. That took me twenty minutes I should not have spent.

Before you start typing anything, know that the Michigan SOS uses a variant matching system. This means it drops articles like "The" and "A," removes punctuation, and occasionally trims plural endings. It does not do phonetic matching. If you are looking for "B & B Contractors," you might need to search "BBContractors" or just "B B Contractors." The search treats spaces as optional separators, which is convenient sometimes and infuriating other times. You can run free searches through the public portal. There is no login required. The standard search returns basic details — entity type, status, formation date, registered agent, and principal office address. A detailed search, which you also run for free, pulls the full document index including amendments, annual reports, and dissolution records. The detailed view shows document numbers you can reference in legal correspondence. If you need certified copies, that is a separate paid service. Standard copies run about $10 each plus a processing fee, and certified copies cost more. Turnaround is usually two to three business days by mail, or same-day if you go to the LARA office in Lansing in person. Do not order certified copies unless you actually need them for court or a closing. Most people do not.
The registered agent field is the most unreliable piece of information on any given search result. Agents change frequently, and there is typically a lag between when a company files its amendment and when the system updates. I had a situation where a client relied on a registered agent address from the SOS database to serve notice, and the agent had resigned six months earlier. The service was rejected. Always cross-reference with the most recent annual report the entity filed, which lists the current agent and sometimes includes a filing date that tells you how stale the data might be. Another thing nobody tells you about the Michigan search: it does not clearly separate professional corporations from standard corporations in the initial results. Both show up as "Corporation" unless you click into the detailed view. If you are searching for a PLLC, P.C., or PC entity, check the entity type code carefully. The status field also uses "Active" and "Inactive," but "Inactive" does not always mean dissolved. It can mean suspended for non-payment of fees, which is a different legal state. A suspended entity can still technically exist, but it cannot conduct business legally until it reinstates. For dissolution checks, the search will show "Withdrawn," "Revoked," or "Dissolved." Withdrawn usually means the entity voluntarily filed paperwork to terminate. Revoked means the state forced the termination, typically for failing to file annual reports or pay taxes. Dissolved is the clean end-of-life status. If you are doing due diligence on an acquisition, do not rely solely on the status field. Pull the full document index and look for any reinstatement filings. An entity can be dissolved and then reinstated within a few years, and the reinstatement does not always appear prominently in the summary view.
Get the Full Details
The Michigan system also does not provide a bulk export feature. If you need to search fifty entities, you have to do it one at a time. I built a simple Google Sheets script that lets you paste a list of names, query the search page, and scrape the results. It saves about twenty minutes per ten-entity batch compared to manual searching, though you should run it during off-peak hours because the SOS site can throttle you if you hit it too fast. A single batch of ten searches usually takes me about four minutes manually, or about a minute with the script. The search tool also does not show ownership or member information for LLCs. That is intentionally kept off the public record in Michigan. You can see managers if they are listed on the formation documents, but actual ownership percentages are not available through the SOS. If you need that level of detail, you have to dig through private operating agreements or request them through discovery if you are already in litigation. When you verify a business registration, the fastest reliable method is to run the name search, open the detailed view, pull the formation document, and then check the most recent annual report for any discrepancies between the stated principal address and the registered agent address. If those two addresses diverge significantly, that is a flag worth investigating. I saw that pattern repeatedly with shell companies that used a commercial agent service for the registered office but listed a residential address as the principal office.
There is no API for the public search. Some third-party services claim to offer one, and they are either scraping the public site (which violates the SOS terms of service) or licensing data from a separate aggregator. For legitimate automated checks, you would need to contact LARA directly about bulk record requests, and those go through a formal process with a response time measured in weeks, not minutes. The search result page does include a link to the SOS "Business Forms" section, which is useful if you decide you need to file something yourself. The form for Articles of Organization, for instance, is available as a fillable PDF. Filing is entirely online through the LARA portal, and the fee for an LLC is currently $50. It takes about five minutes to complete, and you get a confirmation number immediately. Processing time is generally one to two business days for standard filings, with expedited processing available for an additional fee if you need it the same day.
