I can't tell if you said you are a paralegal or the baby's grandmother is?
I am a paralegal, and there is one way to really hack her off if the grandmother is: File a complaint with the State bar association that someone is practicing law or giving legal advice without a license. They'll investigate her. :) hahahahah
BUT, to answer the main question, if you are not married to the father, you can put Daffy Duck on the birth certificate. He CANNOT force you to do so, neither can the hospital. Same goes for name. If they do try to file a paternity suit, it is their burden, they have to pay for the DNA test, etc., and also have to set up child support. That might scare them off.
I wouldn't rule out the possibility that the father or family members want to be a part of the baby's life sometime down the road. Don't give them reason to say you are denying them contact. Keep the line of communication open. But they CANNOT do anything legal without the Court's approval. Stand your ground.
Common Law is based on God's law. Anytime someone is charged under the Common Law, there must be a damaged party. You are free under the Common Law to do anything you please, as long as you do not infringe on the life, liberty, or property of someone else. You have a right to make a fool of yourself provided you do not infringe on the life, liberty, or property of someone else. The Common Law does not allow for any government action which prevents a man from making a fool of himself. For instance, when you cross over the state lines in most states, you will see a sign which says, " BUCKLE YOUR SEAT BELTS - IT'S THE LAW. " This cannot be Common Law, because who would you injure if you did not buckle up? Nobody. This would be compelled performance. But Common Law cannot compel performance. Any violation of Common Law is a CRIMINAL ACT , and is punishable.
Equity Law is law which compels performance. It compels you to perform to the exact letter of any contract that you are under. So, if you have compelled performance, there must be a contract somewhere, and you are being compelled to perform under the obligation of the contract. Now this can only be a civil action - not criminal. In Equity Jurisdiction, you cannot be tried criminally, but you can be compelled to perform to the letter of a contract. If you then refuse to perform as directed by the court, you can be charged with contempt of court, which is a criminal action. Are our seatbelt laws, Equity Laws? No, they are not, because you cannot be penalized or punished for not keeping to the letter of a contract.
This is civil jurisdiction of Compelled Performance which also has Criminal Penalties for not adhering to the letter of the contract, but this only applies to International Contracts. Now we can see what jurisdiction the seatbelt laws (all traffic codes, etc) are under. Whenever there is a penalty for failure to perform (such as willful failure to file), that is Admiralty/Maritime Law and there must be a valid international contract in force.
However, the courts don't want to admit that they are operating under Admiralty/Maritime Jurisdictions, so they took the international law or Law Merchant and adopted it into our codes. That is what the Supreme Court decided in the Erie Railroad case - that the decisions will be based on commercial law or business law and that it will have criminal penalties associated with it. Since they were instructed not to call it, Admiralty Jurisdiction, they call it Statutory Jurisdiction.
