Ksazma, from what I was taught only one time SINDUR can be rub or Brought up... and that is at your first marriage...
Just imagine, you are divorced, re- married 3 times at the time of your death which husband or wife will bring the SINDUR down.
So to clarify, when the woman gets married for the first time, her husband pull up her sindoor. She then reapply it as needed. If she dies, her husband brings down her sindoor. If her husband dies, she brings it down and can never pull it up again even if she remarries. Can this make her appear to be unmarried when she is not?
While I understand the argument if she gets a divorce, doesn't that scenario also make her appear to be unmarried when she is not?
Ksazma, all I know is that my father told me that it can only be done once...
