Reply To: Minhag for a Chosson to move to wife’s city

If you would look into the various old Tenayims, you will see that generally they lived in the in-laws house, for the first two or three years. Don’t forget, they married at very young age, age sixteen was normal, where the daughter probably still needed the mother’s help. Otherwise, I don’t think there is any source. Though there is a source that the first pesach was spent by in laws, in pesachim, regarding Korban pesach.
