Court files are usually public records. If you file a lawsuit, (a) you probably can't prove much in the way of money damages, and (b) a whole bunch of people will be directly exposed to, or have ready access to, everything you say and everything the defense says. Perhaps some of the records could be sealed, but your risk is high. Your mother might become a party or a witness in the case. I'd say the company made a mistake - some file clerk got the names mixed up. This is probably not intentional and almost certainly not policy at the company.
