Traditional wedding roles of the groom's father include standing in the receiving line, toasting the couple at the reception and offering calming support throughout. At the rehearsal dinner, which is co-hosted by the groom's parents, the groom's father toasts the bride's family, the couple and the guests.
The groom's father is welcome to assist with the bachelor party planning, and if the groom's parents choose to have an engagement party for the couple, the father-of-the-groom is responsible for toasting the bride's family.
The groom's parents may offer financial support by helping their son with expenses traditionally paid by the groom. These include the honeymoon, marriage fees and flowers for the bridal party.
