Matrimonial dispute , fake document threat from inlaws

My Friend is  38 year old lady . 

Brief Story:

When she was  15 year old  , Her father wanted to gift her LIC policy . An agent suggested   my friend should have own id  proof   as it makes easy to  withdraw policy when  it  is matured. So her father approached  an agent  to apply for her driving licence  . As  about 20 years ago it was easy to make  driving licence . The agent demanded just photos to  apply for licence  and  said  no proof needed . But  her age on licence   was used as 18 years instead of 15 years .  Key facts of the case are as follows

• She is non driver  and never used her license  to drive . 
• Licence  has correct address/photo's  etc  . It just has incorrect   date of birth 
• This licence is not used  for any fraud to obtain any service by state govt or any  company . 
• She used  it as valid identity proof  almost her whole life  like to open bank account , telephone connection  , railway ticket etc .
• The licence is found fake  after enquiry with  RTO (according to husband)
• She is having matrimonial dispute  so her inlaws  are threating  her  to   indulge her  into fake licence case  .
• As my  friend was mere 15 when she obtained  licence  . so will it considered as juvenile crime. Or she  used it later in life  to obtain bank account/telephone etc  so it will be treated as adult crime ?
• Is there anything that can save her  because she  never knew  it was fake licence and she  never misused  it .  There was no criminal motive  behind it at all . IF she  were aware this thing can trouble her she might have used  her voter card or passport as her id proof 

                                                                                                 Thankyou

This is a case for fake documents.
