I intend to cash a profit sharing check soon, but have a few more questions.
I intend to scan the front and back side with my demand.

1.If I were to deposit the whole check, are there any demands I need to make?

2.Do I need to prove that the backside is actually the same backside of the check I'm cashing, and not some other check?

3.When writing checks do I still sign in cursive first and last or first and middle? Or should I never use cursive and use print only?

4. Is this correct for cashing a check?--->
"Redeemed in lawful money
pursuant to Title 12 U.S.C. § 411
[first and middle name in cursive];dba [name on front in all caps]"


Regarding Freed Gerdes advice:
5.When I send this certified letter with my demand, does the letter need to go to a specific person or can it be sent to standard mail delivery?
Would this be how I would word my demand from a sale?---->
"All sales are redeemed in Lawful Money Pursuant to 12 USC § 411"?

I hope I'm not being a nuisance with these questions, I just want to be sure to get it right.
