Based on the copy of the contract that The Smoking Gun obtained, in order to get the $1,000,000 payday, the couple had to give the ABC reality show's producers final say on everything from the bridal gown to the flowers.
According to the contract, the televised nuptials "shall be a first-class, high-end" affair for which the couple will be "provided meaningful consultation" with respect to all aspects of the wedding, including Rehn's dress, bridesmaid dresses, tuxedos, flowers, cake and music.
However, if there is a disagreement, the show's producer "shall make all final decisions."
Per the terms of the contract, Rehn and Sutter received $100,000 upon signing the contract in May.
They'll receive another $500,000 after exchanging vows, with the balance of the $1,000,000 paid out in equal installments during the show's production.
However, if Rehn and Sutter don't get married, they'll have to return the $100,000 down payment.
The producers also could hold the couple legally liable for breaching the contract.
According to a copy Rehn's original contract for the series also obtained by The Smoking Gun, Rehn's original payment for "The Bachelorette" series was a paltry $15,000 for living expenses and personal trainer fees.
