'Sister Wives': Kody Is 'Tired' of 'the Gossip Mill of Our Broken Family' (Exclusive)

The future of Kody and Janelle Brown 's property is coming into question.

In PEOPLE's exclusive sneak peek at the Sept. 22 episode of Sister Wives , Janelle, 55, gives an update on where she stands with Kody, also 55, as she and her daughter Maddie view a property in Montana that they are considering buying together.

"Kody and I are not in communication," she shares. "Our relationship is over, but we both still live in Flagstaff. Yeah, there's not been an official divorce. I don't know how to get one, and I don't need one."

She then tells Maddie, 28, that she is uncertain about what will happen with the family's shared Coyote Pass property in Flagstaff, Arizona.

"It's not paid off yet. The note is due in about six months," she admits. "They keep asking your dad, and he's like, 'I'm not going to make a plan 'till blah.'"

Janelle then explains how the property is divided amid the breakdown of Kody's marriages to his sister wives Meri , Janelle and Christine . He remains married to Robyn .

"So the first two-acre lot right now is Kody and I. The second two-acre lot is Kody and Robyn. The third is a four-acre lot and it's Meri, myself and Kody," she says as a diagram of the properties is shown. "And then, the five-acre lot, because Christine quit, claimed it is Kody and Robyn. Robyn's got her house. Christine had her house. Meri has built a business, but she didn't use family money. She built that herself."

"So, she and I are both like this represents basically the only asset we would be taking from the marriage," she adds.

When Maddie asks what happens if the note isn't paid, Janelle explains that technically the seller can take back the entire purchase, which she calls "idiotic." However, she is holding out hope that Kody will pay it off, saying, "I'm sure your dad's going to want to pay that off, right?" but Maddie looks unsure.

In a confessional, Janelle explains, "I mean, that's how it's written. The rest of our property is collateral for the note. It's insane to me that Kody is not taking this more seriously."

Kody then shares that Janelle asks him about the property "all the time," adding, "But I don't trust her anymore and so I don't give her any information."

"We will pay off the property when the time comes and I'm not giving you any details about what I'm doing or whatever because I'm tired of disclosing information that goes through the gossip mill of our broken family," he concludes.

Sister Wives airs Sundays at 10 p.m. ET on TLC.
