Is it okay to send cash to someone by mail?

Question

i heard that was illegal or something.

Answer 1

It's not illegal, it's just risky.  If the envelope never gets there, you have no way of proving that it was stolen or anything.  If you send a check or a money order, and it doesn't get there, there's paperwork to back up your word that you sent it.  If you send cash, it's too easily stolen.  

Answer 2

You shouldn’t do it because anyone can take it and spend it. The recipient can simply keep it and claim he/she never got it as well.  Get a money order from Wal-Mart in the recipient’s name and send that instead. I have never heard of it being illegal, but it is definitely not a good idea.
