Quoting
Mr. Knowitall
You stated that her removal of her belongings occurred when the police were present, which is also when they told you that they believed she was still entitled to live there unless you evict her, and apparently also when they told you she could break into the house and they wouldn't do anything. What has changed since that time?
Perhaps what you need to do is talk to the supervisor of the deputy who came to your house, get them to take a position consistent with the law (she wasn't a tenant, and she is no longer a resident of your household) and inform her that she is no longer permitted to enter your premises without permission. One of the lawyers you consulted would likely assist you with that, albeit for a fee.
