Michigan's breach notice rule

Michigan's breach notice section is MCL 445.72, part of the Identity Theft Protection Act, with definitions in MCL 445.63.

Any notice required by the section must be provided without unreasonable delay. Michigan sets no fixed number of days. No regulator notice appears in MCL 445.72.

Without a state office in the loop, the residents themselves are the audience, and the harm exception above decides whether letters go out at all. Businesses that rely on the exception should be able to explain why loss, injury and identity theft were all unlikely.

The harm exception

Notice is not required if the business determines that the security breach has not caused and is not likely to cause substantial loss or injury to, or result in identity theft with respect to, one or more Michigan residents.

The determination is the business's to make, and the wording covers both past and likely future harm.

Our Michigan breach notification page sets out the data elements and the rule in full, and says which text we checked. This is general information, not legal advice.

What a ShareAndGo room gives a Michigan team

Understanding an incident starts with knowing which files were opened, and by whom.

For documents you share through ShareAndGo, the activity log records every view and download, and watermarked view-only pages carry the reader's email address and the date.

Watermarking is set room by room and is on by default. Recipients confirm their email with a six-digit code and need no account, groups see only their folders, and the chained log exports as CSV for anyone reviewing the timeline.

The courts and regulators behind Michigan paperwork

Federal cases from Detroit are heard in the U.S. District Court for the Eastern District of Michigan. CPAs practicing in Michigan are licensed by the Michigan State Board of Accountancy.
