1. No, if your parents are not living together, "parent" is defined as which parent has legal custody of you. 2. Yes, your mom can go to the probate judge in her county and consent to the marriage. She will be issued a document from the court that must be submitted to the court in your county so they have proof of consent. She will need to call the probate court where she is and ask them what their procedure is. Every state/county has their own processes. I know it's none of my business, but I would advise any younger person to think long and hard about their reasons for marriage. I'm not judging. I'm just saying it is a major life decision and there is no pressure for a woman of your age to be tying the knot. If you care to discuss, feel free to message me privately. I am not just a family law attorney, but a woman, a wife and a mother who remembers very well what it is like to be 17. Best of luck to you!
