Thank you for your question. I look forward to working with you to provide you the information you are seeking for educational purposes only.
You do not need an attorney, you need a title/registration service company who will pursue the documents you need. For example: http://registrationexpressgroup.com/vehicle-title-services/
These companies provide duplicate registration/title services in CA and can get you the information you require without dealing with the CA DMV, which is virtually impossible to get any direct assistance from.
I actually tried the first company that you suggested. Their response was unable to assist.
Thank you for your reply.
Other than using one of those companies, you are at the CA DMV mercy to apply for duplicate registration and then duplicate title. The last one on the list has good reviews as well.
