Mich. Comp. Laws § 211.744: Invalidation of assessment; reassessment.

Sec. 4.

Any failure to give notice as required in section 1 shall not invalidate an entire assessment roll but only the assessments on property affected by the lack of notice. A special assessment shall not be declared invalid as to any property if the owner or the party in interest thereof has actually received notice, has waived notice, or has paid any part of the assessment. If any assessment is declared void by court order or judgment, a reassessment against the property may be made.
