Williams -- who also appeared on "Basketball Wives" -- made the shocking statements in a letter he wrote to a Colorado court recently explaining why he could not attend a child support hearing in CO earlier this month.
Williams says a "court-ordered citation for me to appear was not delivered to my home address as I have no home."
Williams also more than $24,000 in unpaid child support to the mother of his 13-year-old son. He says his financial situation is so dire, he can't afford airfare and has no money to pay a lawyer.
In his letter, Williams says he is currently a volunteer at an unnamed non-profit organization -- and says, "I'm in the rebuilding stages of my life."
