I am a CA lawyer.  First, the statute for a minor is 2 years after their 18th birthday.  Next, if your mother or brother had a policy of liability insurance, contact the insurance carrier to defend this case.  If there is no insurance, your family will need to hire an attorney.  Most lawyers will charge an hourly rate to defend this type of case.  It will cost some money, but it is certainly worth the investment.  Look on this list for any lawyer who handles personal injury cases, and start calling to find out what they will charge to defend this matter. 

Yes the statue of limitations or time within which one has to file a suit in the case of a minor is 2 years after she turns 18. I hope you had insurance which you should have had you should turn it over to your carrier immediately or you may lose valuable rights.

If what you said is true of her injuries I wouldn’t worry about the amount because it is not how much they are suing for but what can they prove to a jury. Having tried many cases in the last 25 years I can assure you just because someone asks for $3 million a jury doesn’t automatically award it. You have to prove every penny.
