After getting married, the wife changes her name and adds husband's name. Similarly, the husband should also add wife's name to his. And both can drop their fathers' names.

After the wedding, the wife wears "Mangal Sutra" and applies "Bindi" on her forehead. The married man - the husband - too should find out similar symbolic marks on neck and forehead. And till then, he should copy wearing Mangal Sutra and Bindi.
