What is kinmanship

There is no such thing to my knowledge of giving someone kinmanship. Kinship on the other hand is a definition of a relationship between people, i.e.relationship by blood, marriage, or adoption. There is kinship adoption. You are going to have to be more specific with your question.

Mr. Harkess provided the perfect answer. You can not give someone kinmanship. You can give them guardianship or conservatorship, but not kinmanship.

You cannot give someone kinsmanship. It is unclear what you are looking to do, but a kinsmanship placement usually involves social services taking away a child and putting it with a relative until the parents work out their problems. (your "kin" is your family).
