Late rent notice builder

Before you send it: this builds a reminder letter about overdue rent and a late charge. It is not an eviction notice. A notice to pay rent or quit is a separate document, and Michigan has its own rules for it. Nothing on this page is legal advice.

Rent and invoices follow different laws — consumer debt is not covered

The Invoice tab, the rate card and the statute sections on this page are about business-to-business invoices. Residential rent late fees live in Michigan's landlord-tenant law. Michigan: MCL 554.601 to 554.641; MCL 600.5701 to 600.5759 contains no late fee provision, so there is no legal cap or waiting period to apply; only your lease terms count. Consumer credit has separate, stricter rules. The distinction is explained in B2B invoice late fees vs. residential rent.
