Photo by Kevin Mazur/WireImageThe drama within the Jackson family is not only continuing, it's growing even more convoluted.  A court-appointed child advocate met with Michael Jackson's children Monday night, sources tell ABC News, and is working with them to gain access to Katherine Jackson, Michael Jackson's mother and their legal guardian, who has been away from the kids for over a week.

Court papers will likely be filed this week to demand access to Katherine for the kids. Sources told ABC News that the filing will likely include a request for a temporary guardian in the meantime.  That guardian is expected to be someone already in the children's lives.

The Los Angeles ****** Sheriff's Department responded to a "family disturbance" at the Jackson family home Monday after, sources said, Randy, Jermaine and Janet Jackson showed up and apparently tried to take Michael's kids away.

Sheriff's spokesman Steve Whitmore said Monday there was a "scuffle" between two family members at the Calabasas home of Katherine, but no arrests were made.

TMZ posted a photo of siblings Janet and Jermaine standing outside the home around the time police were called, according to the website.

Katherine Jackson's lawyer, Sandra L. Ribera, issued a statement saying, "Jackson family members ambushed Katherine Jackson's home after their vehicle tore through security gates on the tails of the SUV containing Michael Jackson's children."

Ribera said Michael’s three children, Prince, Paris and Blanket Jackson, were taken to a safe location. "An altercation ensued shortly thereafter and law enforcement arrived at the scene," according to the statement.

This has been the latest drama that has plagued the Jackson family in the past few weeks. Katherine Jackson was reported missing Saturday only to be found "resting" with one of her daughters in Arizona.  It's not clear if Katherine Jackson is aware of the brouhaha surrounding her absence.

Apparently in reference to her grandmother's recent absence from her life, Paris Jackson tweeted Tuesday, "9 days and ********… so help me god i will make whoever did this pay."

Five of Michael Jackson's siblings last week claimed that his will was **** and that the executors of his lucrative estate, John McClain and John Blanca, should step down. Jackson's entire fortune was left to his mother and three kids.

The executors responded in letter posted online Tuesday that they are trying to protect Katherine and Michael’s kids from "undue influences, bullying, greed, and other unfortunate circumstances."

A previously scheduled hearing in the estate case takes place Wednesday.
