The second paragraph of Hataras Nedarim has the person being mattired saying that "I am making a modaah that any oaths being made in the future are considered to be as if 'bli neder'".

Is this legally binding? If yes, why make a hataras nedarim every year?

  • I suggest you change "Is this legally binding? If yes, why make a hataras nedarim every year?" to "If this is legally binding, why make a hataras nedarim every year? And if not, why make it at all?" to focus the question on the every year aspect and not the binding aspect. (This is how I understood the question anyway.)

As its wording implies, the modaa applies only to vows taken when one doesn't remember having issued the modaa. Source: Shulchan Aruch, Yore Dea 211:2, q.v.

    Why repeat it yearly though?

  • @DoubleAA, the question didn't ask why repeat the modaa yearly. It asked, assuming each (year n) modaa is valid, why make a hatara every year (n + 1). And I think that's pretty clear in my answer without my spelling it out.

  • @msh210 I don't think it's so clear. If I were trying to maximise the effectiveness of my modaa, wouldn't I never say it again so that I really do forget about it?
