Kody Brown and his four wives will throw a celebration party in the upcoming episode of the TLC hit realty series "Sister Wives."

In "Chaos in the Cul-de-Sac," TV Guide reports that the judge has reached a decision regarding the adoption of Robyn's three children. Kody is now reportedly allowed to adopt Dayton, Aurora, and Breanna. To celebrate the good news, the Browns will be throwing a big party to which all their friends and loved ones are invited.

Last episode, Kody revealed how important the adoption is for their family. He also shared his doubts that the judge would not understand their polygamist set up. Kody hoped that he would see how loving their large family is and decide favorably. Fortunately for all of them, the adoption request was approved, as the judge could be seen congratulating the Browns for their effort.

Meanwhile, Merry, Kody's first sister wife, also shared her happiness over the judge's decision. Earlier in the season, she magnanimously agreed to divorce her husband so that he could marry Robyn. The adoption would not be possible without that divorce, and Merry knew that. Viewers saw how the separation crippled her, but she still bravely stuck to her choice. Merry said that everything was all about the kids and her personal complications should not be the focus. She also said that giving way to Robyn was worth it, since they got the children.

Also in episode 10, Kody and Janelle got a surprise when their daughter Madison told them she was dating. The teenager told her parents that she was in a serious relationship with Caleb Brush, Kody's brother's brother-in-law. Kody and Janelle approved of the relationship, as her father told Madison he could not have picked anyone better for her.

"Sister Wives" airs Sundays at 9 p.m. EST on TLC.
