Back story.
We have a friend who is having troubles keeping her life together. I'm not aware of all the issues. However, they include an abusive husband (who has now been kicked out), financial troubles, and probably no shortage of poor life decisions on her part. We've heard through the grape-vine that her children may be removed from the house by the state.
At the same time (but until today entirely unrelated), my wife and I have been considering Adoption/Foster care. I've not been a fan of foster care (preferring adoption), but would be willing to make an exception in the case of helping out a friend. Losing your dad, and then your mom (even temporarily) is bad enough. At least staying with someone you know is better than with a complete stranger.
The question Assuming the kids will be put in to foster care for some period of time, how would (or could) this work? Does the system consider a friend offering to take them in?
I'll try to answer any clarifying questions I can, but at the moment this is theoretical (rumor).
Clarifying facts: We are in the US.
