Hello! So, I had invited some great-aunts and uncles to our wedding that I hadn't seen in years. They are my father's relatives and he wanted to invite them and offered to pay for them so how could I say no? Not really the point - moving on - so Uncle X and Aunt X didn't make it to the wedding, but did send a card afterwards. They gave us a check and made it out to "CASH" instead of our names.
Apparently banks no longer accept this and haven't for years (aunt and uncle are older people). So my question (finally) - how should we go about addressing this?
I feel like it would be rude to get in touch with someone that I haven't spoken to in years to say "HEY! Can you send a new check with our names?!

"
Should I just mention it to my dad and see if he will say something to them?
I would just take the loss of money and never bring it up, but I also feel like when you write a check..you expect that money to come out of your account at some point? So therefore I also feel rude just making them wonder why their bank balance is off for the rest of time....
Suggestions as to what to do? Thanks ladies!
