"All my truth will soon be revealed," Walls, 27, posted on her Instagram story. "A lot to be told and owned. But only healing and a beautiful life to come from all the pain I am overcoming. All I ask is to be patient with me. I love everyone with all I have."
As RadarOnline.com exclusively reported, court papers obtained from Travis County Court in Texas revealed her parents Cally and Michael Shapshak asked the court to grant them sole custody of Harper London, 2, from Walls and Raines.
"Cally and Michael have had possession of the child since date of birth," the original petition filed on April 16, 2018 read. "The appointment of the parents as managing conservators would not be in the best interest of the child. It is in the best interest of the child that Petitioners be appointed sole managing conservators of the child."
In Walls' response to the petition, filed on July 13, 2018, she wrote, "I want my parents to have custody of my daughter."
Raines, who also shares younger daughter Isla with girlfriend Alyssa Giacone, refused to sign over his rights.
"Respondent admits that Petitioners have had possession of the child," his response filed on August 23, 2018 read. "However, the mother, Madison Channing Walls, was living with petitioners at the time and it is believed that she will likely continue to do so in the future."
The Challenge: Vendettas star denies that appointing him and Walls, 27, as managing conservators would not be in the best interest of Harper.
"Respondent also specifically denies the allegation that it is in the best interest of the child that Petitioners, the child's grandparents, be appointed sole managing conservators of the child," the papers read.
The 30-year-old dad believes the parties will enter into a written agreement containing provision for conservatorship of, possession of, access to, and support of the child. If the parties do not come up with an agreement then he "requests that the court make orders for conservatorship."
The custody battle comes amid speculation that the Real World: Skeletons star relapsed on heroin.
In a now-deleted Instagram post, Walls appeared scary skinny. She also seemed to have track marks on the inside of her arm.
She has been posting less on social media. When she does, it is often selfies or older photos.
"I had to go off grid… I'll be back soon," she captioned a photo with her daughter on September 7. "Thank you for all of your support."

Her mother denied drug rumors, as she told RadarOnline.com, "She's doing great. Nothing is wrong. She's fine. No she's not on drugs."
She added of the custody filing, "The conservatorship is because it's our family raising Harper. Tony isn't involved. We just want to protect her. He does post about her a lot on social media, especially for someone not on the birth certificate."
Walls struggled with addiction issues in the past, even admitting to overdosing on more than one occasion.
"I'm a recovering heroin addict," she said on Real World: Skeletons. "I am scarred for life from it. I just feel grateful to be alive."
RadarOnline.com broke that Walls was arrested on May 24, 2013 for possession of narcotic paraphernalia and attempted theft.
During a search of her bag after being busted stealing from a CVS store, the reporting officer wrote in the police report, "The bag had some spoons partially sticking out of one end and I asked Madison if that was her drug bag and she said yes. I asked if there were needles in it and she said yes there might be. I opened the bag and it had two syringes and three spoons that were burned from heating heroin."
While searched at the jail, officers found that her body was covered in track marks.
"It should be noted that Madison's arms were covered with track marks from needles and when she was searched at the jail," the report read. "The deputies informed me that she had oozing sores on her butt from what Madison admitted to be from shooting drugs in her butt cheek area."
Walls pled guilty and was ordered to pay $220 in fines and court costs.
