Please explain what "on paper" means in this context.
That's good parenting, but it does raise a question.
If this child is not your child but you and your wife have been married for nine years, that suggests the child is more than nine years old, which is plenty old enough to understand that "dad" means. How old is the child?
Given that you've been married for nine years, I sure hope you filed separate returns the other seven years.
Subject to how you answer the question about the child's age, no and no. If you divorce your wife, you may be able to seek visitation with her child. You'll need to give the child's father notice of any such proceeding, and both your wife and the child's father can oppose your request.
