Your child can be adopted without your consent.......

If you are man in Illinois or Indiana, and you think you have fathered a child out of wedlock, it is critical that you register with the putative father registry or establish paternity immediately after the child's birth in order to prevent the child from being adopted without your consent. Even if you and the mother are "getting along," in order to ensure decisions are not made without your consent, you must either register as the putative father or legally establish paternity within very specific timeframes after the child's birth.
