Not me but my late father had the error in his DOB (date of birth) we believed prior to his passing is the day of our town fiesta. Turns out it isn't and it is two months prior to that.
We had trouble in processing his paperworks as his ID is the first DOB but later on we used the correct one for the sake of uniformity.
Hopefully it will not create any problems in the long run.
Since we do not have any inheritance to receive I guess that's fine 😆 we will just cross the bridge when we get there.
It's not that big deal cause you can supply any affidavit on it sign by a lawyer.
