Since the terms of service and usage of this site clearly state that this site is not a substitute for legal counsel, I didn't feel it necessary to take up bandwidth repeating it ( ad nauseum). At no time did I ever suggest that the OP do any of the things I suggested on his own. People don't come to this site asking to be told to call an attorney. They come to this site for OTHER people's opinions, suggestions and input. To continually disparage the same reflects on your real reason for even participating here in the first place.

But, I digress.....

A little lesson in jurisdictions: The Indiana court has no jurisdiction in this case because any action brought against the OP is done through a California court. That is where the child is, that is where the action originated. Obviously, he needs to hire an attorney located in California, not Indiana (not to mention the logistics of finding one that happens to hold dual licensure in both states so far removed from one another). Indiana laws are not relevant, unless she, for some bizarre reason brings an action against him in his locale. I am, however, having trouble thinking of a case where that would be necessary. A California court may appeal to an Indiana court for enforcement if the OP is not in compliance with the California court order, but no cause of action should originate in Indiana since the woman, and the child, etc. are all in California.

As I stated, "Of course, my comments are prefaced with the caveat that a paternity test is first order of business." ( pause a weighty moment for the obvious to dawn).
