Can a wife called her husband with her name or not. Is it haram for a wife to call a husband with her name. I heard a majlis from an alim in that he is saying so. please advice.

It is not haram itself but it can become haram if it is done in a degrading way, or the husband does not like it and it hurts him. Same goes to the wife, meaning the husband and wife both should address each other respectfully.
