My mother died recently leaving behind me and my four siblings. I am 25 and have a stable home with my fiancé. Our father left when I was 14 and has not been in contact since. My siblings (three boys and a girl) have been placed with me and my fiancé temporarily. What are my rights regarding adoption and how would I go about doing so?

Is there a need to adopt?

You (and they) may be better served by just working to become their legal guardian.

This is a situation that I would DEFINITELY talk to a lawyer about. You want to find out what the best thing to do for yourself and your siblings would be---and that can vary by location and circumstances.
