Frieda says she "built" the home with Chris roughly 12 years ago -- but since then, their relationship has deteriorated and he's been trying to evict her. Frieda says the two haven't spoken in 5 years.
To combat the eviction, Frieda says she's had to hire lawyers -- and has been forced to rent out the home to various tenants to cover the pricey legal bills.
Long story short ... Frieda says the person who brought trouble to the home is a former short-term tenant -- and she had NOTHING to do with his alleged illegal activity.
FYI, cops believe crack cocaine and heroin were being trafficked out of the home. No arrests have been made, but we're told that could happen soon.
Joel Bosh says he's been trying to help his mom work things out with Chris -- but his priority is helping her clear her name in the drug trafficking case because he believes she's 100% innocent.
Despite the family drama, both Frieda and Joel say they love Chris and hope they can reconcile soon.
