Grown daughter, 25, working & fully able to be self-supporting. (We dont get along, we have a host-parasite relationship). The police say I need to give her 30 days notice then follow legal procedings as though she were a tenant. So 2 days ago I prepared eviction notice, mailed certified, emailed, & posted on bedroom door. She stormed out of the house not to be heard from since. Am I within my rights to change locks & security codes and bar her from returning? I have no problems returning personal property.
