Separate Mailing addresses required at Separation?

My husband is always on the road and comes home Thurs. PM to Sunday PM. My thoughts for separation is until our home is sold, he can just not come home on the weekends and go live with relatives on the weekends. If he wanted to come home on the weekends, then I would leave for that weekend.

Do we legally need separate mailing addresses while we are going through the one year of separation?

You just need to be living separate and apart (not under the same roof). He doesn’t need to necessarily change his mailing address, but if he later decides to contest the date of separation you would want to make sure you have proof that you were truly separated on your date of separation.
