my sis-in-law's driver license has a wrong b-day, 5 years older and different date.

she got her license long before LTO go computerize,

is it possible for her to correct it? will it be any penalty? anyone experience this and what is the best way to correct it?

btw she just renewed her license at the satellite office last year, but she really wants to correct it now,

any help is greatly appreciated.
