In addition to defaulting on a $23 million loan secured by his Neverland Ranch, the singer is said to be in tax default on his parents' home in Encino, Calif. According to Friedman, the house was on the county's defaulted tax roll as of Wednesday.

"If someone doesn't pay the county $16,293.10 by this Monday, there's going to be trouble with the county," Friedman wrote in his Thursday column. "Jackson has a $4 million mortgage on the property where his parents and various family members alight from time to time."

As Freidman previously reported, Jackson has until Jan. 19 to pay the full amount of his Neverland-secured loan to New York's Fortress Investments, the first publicly traded hedge fund. If he fails to do so, the property will go into foreclosure.

So far, no payments have been made and Jackson remains in default, Freidman wrote.
