Definitely. Even though the law uses the term “separate and apart”, you can live separate and apart under the same roof. Many couples already do this to financially support housing and living costs and their childern. So long as you do not have sex with your spouse or do any of the things that would make a court determine there was no legal separation, you can live together. The Divorce Act also allows couples to resume cohabitation for the purposes of reconciliation without interrupting their legal separation. The cohabitation must not span more than 90 days though.
