Yes. That is typically accomplished by disinheriting that child in your Will.
To be allowed to be adopted as an adult you already have to have a bond with this person like a step parent etc. The different states are very strict with this and if I were you I would avoid Michigan because they hardly ever allow it even when you have a close bond.
Disowning a child is not a legal concept, and there are no rules. Commonly, people refer to a parent writing an adult child out of his/her will as disowning a child. In this case, yes, the parent could write them out and write them back in again as often as they want.
drop him of at a foster home
Yes. You just have to write in your will that your adult child gets NOTHING.
In most countries, parents cannot legally disown their adult child in the sense of completely severing legal ties, such as disinheritance. However, parents can choose to have no contact or relationship with their adult child, which is not the same as disowning them in a legal sense.
A parent that gives permission for a minor to have sex with an adult is committing a crime, as is the adult with whom the minor has sex. Think about it. If it is okay for a parent to give permission for a minor to have sex with an adult, at what age is ok? 15? 12? 10? What about 4 or 5? It is the responsibility of the parent to protect their minor child.
It would be best to consult with a family law attorney in your jurisdiction to determine the specific legal documents needed to disown your adult child. The process can vary depending on the laws in your state or country.
There is not much you can do except wait for adult age to leave or emancipate if you have cause or perhaps you can meet with both parents & they can mutually agree to guardianship of the other until you are of age.
you can get emancipated. it's like divorcing you parents and they don't have any legal rights over you anymore as guardians but you have to look out for yourself. but they have to sign the papers i think, you can't just go do it without them knowing and if your already an adult you could change your last name
No.
A parent can get the medical records of an adult child if the adult child gives express permission.
