A lender filed a foreclosure complaint against Anthony’s mother, Cindy, earlier this month.
Nationstar Mortgage says Cindy Anthony owes almost $129,000 on the house. The lender says it hasn’t received a payment since 2011.
Casey Anthony lived at the house with her daughter, Caylee, and her parents until 2008 when she was arrested in the toddler’s killing.
Anthony was acquitted of murder at her 2011 trial.
After Caylee’s 2008 disappearance, protesters gathered outside the house demanding Anthony’s arrest.
The house also was searched by detectives investigating the disappearance. Items seized from the house were used as evidence at trial.
The parents’ attorney didn’t immediately respond to an email or phone message.
