>>HALACHAH: It is not clear from the Poskim to what extent a decree needs a Beis Din in order to be annulled. The DARCHEI MOSHE (YD 231) seems to rule stringently, like Rashi, that even a Cherem or Takanah which was enacted for a specific amount of time needs the annulment of Beis Din. The SHULCHAN ARUCH (YD 334:13, 27) seems to rule stringently even in the case of a Cherem upon an individual, which, he rules, will not become annulled by itself even after its stated time period has passed.<<

At the end of this piece, you suggest the Darchei Moshe is machmir like Rashi. I looked up this sif and it appears (see the end of the Rema D"H umehu) that the Rema is makel--the neder automically goes away after the specified amount of time? Also see Gr"a there. thanks
