Name Change conflict with Biological Father's obligations
When my parents got divorced, it states in the divorce decree that my biological father is obligated to pay for 50% of my college expenses. He agreed to it and we have record (his agreement in the divorce decree). I am nineteen now and going in to College and would like to change my last name due to the desire to no longer be associated with him any longer. If he were to attempt to take the decree to court on the grounds that I changed my last name so he should be removed from his obligations, would this even be a possibility? Would a judge even hear the case or would it be dismissed immediately? I do not have the money to pay for attorney fees, ergo, I would like to know the possibility.
For my own personal comfort, responses are greatly appreciated, but ethos and credentials would be valued so I know I am getting actual facts and advice. Much obliged.
