Traditionally, the groom's parents pay for the rehearsal dinner, some of the wedding flowers, gifts and certain attire for groomsmen and some aspects of the reception. Today's customs allow for the groom's parents to contribute to the full wedding budget or even pay for the entire wedding themselves. The decision depends on the couple, both sets of parents and the available finances.
Customarily, the groom's parents pay for the entire cost of the rehearsal dinner. This includes the cost of the food and the rental fees for the venue. Decorations and entertainment, if requested, are also covered by his family.
The groom's family pays the wedding officiant's fees and his lodging and transportation costs if the officiant is present at the ofamily's request. If the officiant doesn't have a fee, the groom's family makes a donation in the officiant's name to the church or organization of the officiant's choice.
It is traditional for the groom's parents to pay for the bridal bouquet in some areas, her going away corsage, boutonnières for the groomsmen and corsages for the mothers and other immediate family members on both sides. Some florists offer bridal packages that include the corsages; in that case, the bride pays for them.
Gifts for the groomsmen and ties or other accessories not included in their tuxedo rental package are the groom's parents' responsibility. They pay for transportation to the wedding for the groom and his best man. His parents also cover the cost of the marriage license and any associated fees.
At the reception, the groom's family typically covers the cost of the liquor. They also pay for the band, DJ or other musical entertainment at the reception.
