If after marriage, I take both my and my spouses last names, would I need to update documents such as my passport and driver's license?
John Apple ==> John Apple Pear Jane Pear ==> Jane Apple Pear
The goal would be to have matching last names to avoid problems with things like hospital visitations, child pickups, etc. where last names are often used to verify relationships.
But at the same time, having to reconfigure all our legal documents would be rather painful. Not to mention gaining access to old bank accounts and things.
