How would 2 God-Parents be able to get custody of our God-Child?

The mother can make a will and state her wishes for whom she wants to care for her child,however even with a will,if there is a fater out there,then the father will be the one to be able to get the child,even a family member would have a better chance than a non-relative. I think God parents is great,but being God parents does not mean that you can get custody,or the mother can leave the child in your care. If the father finds that the mother was ever deceased then he would be able to file for custody. Being unstable can mean alot of different things,will he always be? My sujestion is for the mother to leave a will,and to talk to all family members and let them aware of her wishes,so that they will not interfere if the father decides he does not want to raise the child,and the father can give you custody,if anything happened if he wants to. But you know all though I understand where your coming from, I am sure this may never occur,and the mother will live to raise her child,being perpared for the future is a good thing,but we really don't forsee these things as happening.
