<prompt> Human: I have a family member who lives with some real scumbags. The last check I wrote them was stolen and luckily they realized and let me know before the scumbag could cash it. Is there a way to ensure that a check I write cannot be endorsed? Im guessing that was the scums plan because how else would a check be useful? Can I just write Do not allow endorsement or something below the endorsement line?  <response>: To do this, banks prefer, For deposit only on the back of the check. Write it twice. And make sure you line out any open space on the payee section. Write your numerical amounts like this: ---1,234.00xx--- small 00 and bar ___ on top of xxId be more worried about other things, those scumbags could be doing to your family member. If theyre willing to steal hisher mail and defraud, thats just the beginning. Your family member should leave that roommate arrangement.
