@Mike SchorahI see this all of the time in Florida; as the law reads (I imagine it is pretty similar in other states as well):In Florida, it is unlawful to engage in the following real estate related activities for compensation without possessing a real estate broker’s license or sales associate license.Advertising or marketing another person’s timeshare or property for compensation.Auctioning or attempting to auction another person’s property for compensation.Buying or attempting to buy real estate on behalf of another person for compensation.Listing another person’s timeshare or property for compensation.Operating as a real estate broker or sales associate without a license.Renting, leasing, or attempting to rent or lease real estate on behalf of another person for compensation.

Also specifically, I can not file for an unlawful detainer on the basis of tenants not paying RUBS. 

In California, this involves filing an unlawful detainer claim in the appropriate courthouse and then properly serving the tenant.

My landlord performed an unlawful eviction and conversion of my personal property.

Unless there are unlawful terms in the Agreement, they will typically interpret it at face value.

If your state allows unlawful detainers for utilities, that's your best option.

The city had to pay damages for an unlawful taking.In 2005 the State of Michigan adopted into the STATE CONSTITUTION that cities can not use eminent domain for economic gain.

Specifically, a landlord may be able to serve the 3 day notice to pay or quit, but filing an unlawful detainer action is probably best left to an attorney the first time around.Originally posted by @Mike Franco:...I also have a judgment from a long time ago, and I didn't renew it...Just in case you are not aware, judgements in CA are good for 10 years and may be renewed for another 10 years, then 5 years.

We're currently going through formalized eviction with our tenants because they refused to leave so now it's an unlawful detainer case.
