There currently is not a standard adoption policy in Michigan. Therefore, the procedures that one must go through to successfully adopt a child can vary greatly from county to county. Additionally, the adoption code is complicated. A private adoption generally takes anywhere between 12 to 24 months. However, this time period can vary depending on the circumstances of each individual case. Home studies are required as part of the adoption process. There are a number of other requirements that must be met as well which vary depending upon the county in which the adoption is taking place.
