No, she truly owns her condo. The property is hers.

So that's why it's difficult. But it's not impossible.
It's just a matter of bringing it to court.

But that takes awhile, even with full support from the condo council.
Still, she's made everyone an enemy, so I think she'll eventually be ordered to leave.

So far, she's just paying massive fines for violating my "right to quiet enjoyment".
