My name isXXXXX a licensed attorney. Glad to try and help out.
Sure sorry for the circumstances, truly. My heart goes out to you.
Accordingly, I'm pleased to share some good news with you, as follows. When it comes to family law help, California is a great state in which to reside. In fact, you can access a bounty of free help (information, forms, instructions) by clicking the following link:
California Judicial Council
In addition to seeking this type of help online, there is also a free resource where you can speak with family law staff in person. To do so, just select your county from the following application:
Self Help Centers
Also, free or reduced fee family law legal services are available here:
Free and Low-Cost Legal Help
Now, I also sense your very understandable concern over the issue of losing your child. Please know that what your husband is threatening would be a very serious crime. For that reason I'm very happy to provide you with peace of mind. There is a program whereby you can act right now (no need to wait until filing for divorce) to prevent an unlawful child abduction from taking place. Here is everything you need to take advantage of that option:
Children's Passport Issuance Alert Program
If you have a follow-up question or need clarification, please just say the word by using "reply" to reach me.
I truly hope all works out for you.
