Dad and I have a good relationship and are just not married. We share expenses for our son and really don't split hairs. That's why I really don't have any documentation because I never really thought I would need any. The reason I am concerned is I have a friend in a similar situation who is being verified for this credit. I want to be prepared. I figured I would throw it out there and ask any tax experts who may have had this or a similar situation arise in their professional career.
Thanks for all the replies!
