The arrangement means that Blackstock, 43, will receive $195,601 in total from Clarkson each month, or roughly $2.4 million per year. The order also requires the singer to pay $1.25 million towards her estranged husband's attorney fees and costs for their ongoing divorce.
A source previously told PEOPLE that Blackstock had been
aiming for more than double the amount in support, requesting that Clarkson pay him $436,000 per month ($301,000 in spousal support and $135,000 in child support).
Clarkson is being represented by celebrity attorney Laura Wasser, who recently launched
It's Over Easy. The service helps streamline the divorce process for individuals who might not be able to obtain her services otherwise.
