MCL 552.605b Child support after 18 years of age. Sec.b

That statute references support  for a child between 18 and 191/2 years of age.  Yes all three requirements  are necessary for support to continue beyond 18 until the 191/2 cut off.  Those requirements are that the child is regularly attending high school on a full time basis, the child has a reasonable expectation of graduating from high school and the child is living full time with the recipient of child support or at an institution.  There is no statutory requirement for support beyond 191/2 years.  This response is general in nature and is not legal advice.  No attorney client relationship is formed by it.
