Assalamu alaykum, Ustadh. I bought a car but the bill of sale shows a lower price agreed by my mom and seller without my knowledge. I want to correct it but she won’t cooperate. How do I fulfill my duty to honesty while respecting her and handling her disobedience? JazakAllahu khair.

I need more info, why is this? Is there like stealing that will happen because of this or forgery or something like that which is forbidden.
