Hakeemul Ummat Hazrat Mawlana Ashraf Ali Thanawi ra said;

“In this day and age it is most appropriate that soon after marriage adult children live separate from their parents. This is blissful for both of them.”

Tuhfa e zowjain, page 2

“This separate residence is an essential (wajib) right of the wife (when she demands it). Even if parents oppose (moving out), they are not to be obeyed.”
