Brown, who is also married, not legally, to Christine and Janelle, explained the decision was made by the entire family.

"We have chosen to legally restructure our family," the Brown family said in a statement obtained by E! News. "We made this decision together as a family. We are grateful to our family, friends and fans for all their love and support."

Robyn's marriage woes played out on the TLC show about the polygamist family. She admitted on camera her doubts in being a part of a "plural marriage."

"I'm happy on the good days and when Kody shows love and affection, but on a bad day, I question my importance to the family and if Kody still care about me," Robyn admitted on "Sister Wives."

Brown has 1 child with Meri, 6 with Janelle, 6 with Christine, 1 with Robyn who has 3 children from a previous relationship.
