When one lends money to someone and writes a shtar (promissory note), what should it say?
Answer:
It should say something like:
I hereby declare that I owe [Name] $[Amount], which must be paid by [Date, and/or Installments].
Signed this [day] of [month, year],
[Name].
If you wish, the shtar can be countersigned by two witnesses, which gives it extra power in reclaiming the debt.
