[Avodah] minhag shtus

[Micha Berger via Avodah]

The AhS YD 214:21-23 is relevent. Unfortunately, it's from his coverage
of Nedarim, which means that only the newer editions of AhS have it.

He cites the Shakh s"q 7 (d"h "vechayavim la'asos ketaqanasam"). The
Shakh distinguishes between a minhag garua and a minhag chshuv. The latter
defined as "shenahagu kein al pi talmid chakham". There is an obligation
for a visitor to follow a minhag garua when bifneihem or when the only
witness is a TC who will understand. (The Shakh phrases it in terms of
when there is no chiyuv.)

So it seems a minhag does NOT require a TC. But it is indeed weaker than
one that was launched by a TC.

Tir'u baTov!
