Where does a divorced woman observe her waiting period?

Question:
For women divorced with a final or minor divorce, their waiting period is always observed outside the husband's house?

Answer:
For a woman whose divorce is revocable, she stays in the husband's house if it is feasible. If it is not feasible, she goes to her family.
As for a woman divorced with a final divorce, no, it is forbidden for her to stay there. Once she is no longer his wife, if he divorced her three times or divorced her through mutual consent, she leaves.
So, if a woman whose divorce is revocable is with him, he may take her back. That is, her presence with him is one of the reasons for taking her back, provided he had divorced her twice after having consummated the marriage.
