... residency means domicile.
Cite?
"Resident" is not defined in Ch. 140 §121, at least.
Mass tax guidance...
Your domicile, or legal residence, is your true home or main residence. You may have multiple residences at one time, but only 1 domicile.
....(which happens to agree with ATF gun regs,
although who knows if that's sheer coincidence).
Mass LO's may disallow a choice of LTC residences,
but so far neither of us I can point to written law saying that.
The EOPSS/DCJIS LTC application calls for "residence address",
but neither the form nor the cover page on the web defines it.
Ah! It
does call for Drivers License Number.
No police department will neglect to cross-match
that info.
