My mother's information is incorrect.

 She did not pass in 2003. How do I correct it?

If this is her profile in the FSFT (FamilySearch Family Tree), the format is fully open-edit. You - or anyone with knowledge - is able to edit/correct/change the dates entered.

If the profile is for someone still living, you can request that it be modified to show that she is not deceased.
