One of the last big things on the list is to finish up is the placecards. I have a couple ppl last names that I have no clue what they are but slowly figuring them out. I'm trying to collect them all so there aren't any just first name cards. My one dilemma is FI coworker. He lives with his gf and they have two kids. I know they are not married but they wrote her in on the rsvp card with his last name... I have no idea what her actual last name is. My main problem with writing her in with his last name is that it's commen knowledge among that group that they aren't married so she can continue to collect/ take advantage of single motherhood programs, tax deductions etc. This really irks me a on personal level but I'm at a loss as to how handle it.
