Good morning Kimberly,
I'm Doug, and I'm very sorry to hear of your situation. My goal is to provide you with excellent service today. I have been a CA licensed attorney for more than 3 decades and I handle family law matters.
This seems like a very crucial matter for you, and your questions and issues suggest that an in-depth conversation might best suit your needs. If you are interested, for a very nominal charge of just an additional $5, I can offer you a private phone conference as opposed to continuing in this question and answer thread which is searchable and viewable by the public.
Let me know if you don't want a call and I will be happy continue here with an answer for you.
Either way, whether I call you or not, in order to give you a clear and concise answer, I will need some additional information about the circumstances, please.
1. You refer to a common law partner. Do you claim that you are common law married? If so, in what state were you common law married?
2. Please tell me what the other parent is asking for in terms of custody or visitation?
3. Between you and your partner, who was the primary parent raising your son during the relationship?
4. Do you work outside the home? Does your partner work outside the home?
Thanks in advance,
