Q. Does a woman have to make her own Pruzbul at the end of the Shemita year?
A. See questions 614, 871, 872, 873, and 879 on the meaning and Halachos of Pruzbul.
Horav Shlomo Miller's Shlit'a opinion is that in general circumstances she can rely on her husbands Pruzbul.
For other important details applicable in different cases, a competent Rov should be consulted,
