Children residing with stepparent instead of parent
Maybe this is a waste of time, and I'm sorry in advance if it is.
Right now, my two stepchildren are primarily residing with my husband and myself. Their mother has visitation 3 weekends a month. She works 3rd shift and was leaving the kids alone in the middle of the night to go to work, and her fiancé also has a problem with alcohol; both of these factored greatly into the physical custody change.
My question is: is there anything we can do to ensure the kids would stay with me if, God forbid, something happened to my husband? His exwife would never sign away her rights and allow me to adopt the kids, but is there a way we could assign guardianship or something similar that would allow me to still be a part of their lives?
I'm worried not just for myself, but also for my 2 1/2 year old. It would hurt her terribly to suddenly have her brother and sister taken away from her and knowing his exwife, she wouldn't let me see them if she wasn't receiving child support.
