"In Michigan, embalming is not required except in limited circumstances. For example, if a body is not buried or cremated within 48 hours, embalming may be required for transportation purposes. Embalming is also required if the death was due to certain rare, communicable diseases."
"Although funeral homes may sometimes be very pushy about getting you to buy caskets from them, federal law requires funeral homes to accept caskets that consumers have purchased from another source, such as an online retailer. (Learn more about your consumer rights under the FTC Funeral Rule.) You may also build your own casket if you prefer."
"...burial on private property is sometimes possible in Michigan. Michigan state law allows for the creation of private burial grounds of less than an acre outside city or village limits. ... it will then be exempt from taxation.
Before conducting a backyard burial or establishing a family cemetery, you will need zoning approval and a permit from the local health department."
So basically, you can do anything you want with dead people. I might even dig my own grave. I bet I can get out of this shit for like 200 bucks.
