Q. See question above: Does a woman that usually davens every day also daven Ma’ariv?
A. Most Poskim maintain that women are not obligated to daven Ma’ariv, since Ma’ariv was initially established as a voluntary prayer even for men, and while eventually men accepted Ma’ariv as an obligation, women did not.
A minority opinion holds that women should daven Ma’ariv as well if they are able due to their family and home duties. See Aruch ha-Shulchan 3.106:7 and Kaf Ha-Chayim 299:62, and this is the custom of some women.
