Honestly I never had to deal with any of that. I knew my sisters case workers since she had two children that were already removed from her care who lived with my parents. So when the third child was removed from her care the social worker called me and asked if I was willing to take her in. And then I just had to go and pick her up from social services. I know now days in this state that even with relative placement the relatives have to get their foster care license but back then (4 years ago) they didn't.
mamma_anna was the other one who did a kinship adoption through foster care. She might have more insight than I do.
