Auto Insurance Claims: liability for minor, s driver, liability laws

Question
My former wife (Mother) has physical custody of my 16 year-old daughter, we share legal custody.  A court order allows Mother to make decisions if we disagree.  Last September (upon adoption of said Order) Mother signed CA DMV form DL-44 and got my daughter her permit against my objections (daughter's attitude and behavior).  Now that daughter has changed, I have allowed her to drive somewhat.  When Mother found out she demanded that I not let her drive and is now demanding that I sign a new DL-44.  She refuses to complete daughter's driver's training or take her to get her license until I sign).  I refuse because I have some serious trust issues with Mother and do not want to be liable for my daughter while she is under Mother's principle control.  I have no problem being liable for my daughter when she is driving with me (or one of my vehicles once she gets her license).  My question is this: is my signature necessary on the DL-44?  Am I not liable for her actions when she is with me under other CA laws (NOT the DL-44)?  How can I show Mother that my signature is not necessary on the DL-44 and that I am liable for my daughter’s actions while she is under my control?

Answer
Hi Mike,

Unfortunately, this question is regarding very state specific DMV regulations and liability laws. This is not a question regarding insurance claims.

You will need to direct this question to the California DMV or to a California attorney that specializes in liability of parents for acts of their minor children.

I hope this helps
