> Show a birth certificate and get an ID. Not a big deal.
It’s apparently a bit more complicated for a lot of women since they have to show all the supporting documentation for name changes. For instance, my mother is divorced and remarried, so she had to bring a birth certificate and two marriage licenses (plus name change applications) as supporting documentation showing progression of her last name from birth until present day.
Another very common thing in the US is having to validate your dependents for employer-provided health insurance. Since most married couples use just one of the spouses' insurance for cost reasons (even if both of them have jobs that provide it), this involves submitting copies of your marriage license as well as birth certificates for all children. This has been a thing for years and I've had to do it a few times. Like getting a RealID, it's a bit of a hassle but not that big of a deal for 99% of people.
