My legal name situation is a mess after getting married as an American to a Dutch man in NL.
I’m at the hospital for an appointment. I give my American passport name at the front desk. They can’t find me. I give them my husband’s last name and they find me and check me in.
I go upstairs to the right department. I give them my husband’s last name. They can’t find me. I give them my American name and they can verify I’m checked in
