Legal Question in Family Law in Louisiana

You don't have to, but it will no doubt come back to haunt you in the future. I have seen it many times. Some friend or enemy of you will tell someone who will tell the father and then he will come forward and cause you problems. Best thing to do is to tell him and then demand he pays pre-natal care, pay for the birth and after the birth pay child support! Then later if your new man wants to adopt, it will be easier if the bio dad has not done any or only part of the above.
