I believe as of now pre covid evictions have been frozen and current unlawful detainer paperwork isint being accepted by the California courts from what I’ve been told by neighbors/friends and local investors. 

For example, there are ways to look up a person and find out if they’re party to an unlawful detainer action (eviction), or look up a property and find out if there are any past due property taxes or code enforcement liens.

I suspect you will have to file the equivalent of a forcible detainer action in California in a few months time and pursue an eviction and back rent. 

You will likely have to go through the standard eviction/unlawful detainer process in your jurisdiction.Please note that the CARES Act has not prohibited eviction on the basis of anything other than nonpayment of rent, however, your local jurisdiction may have put a hold on evictions.

I have contacted an attorney for advice and was told to file an Unlawful Detainer lawsuit, but unfortunately, the moratorium is preventing us from exercising our legal rights to do so.

This was changed a few years ago.https://le.utah.gov/xcode/Title78B/Chapter6/78B-6-S802.htmlA tenant holding real property for a term less than life is guilty of an unlawful detainer if the tenant...continues in possession of the property in person or by subtenant after the end of any month or period, in cases where the owner, the owner's designated agent, or any successor in estate of the owner, 15 calendar days or more before the end of that month or period, has served notice requiring the tenant to quit the premises at the expiration of that month or period...

But an eviction means they refused to and they forced another landlord to sue and go through an unlawful detainer action to recover possession of the property.

And that I need to file an unlawful detainer I argue with them I told them that I lived on the property that the person what's a lodger who is unwanted never had a rental agreement never paid rent I refuse to leave and I also explained.

@Tiffany M. in our area if you file for anything outside of non-payment the court has proceeded w/ the forcible detainer (eviction). 

If they don't leave, then you file for unlawful detainer (eviction action)You can pursue them for damages and unpaid rent no matter which method you choose.
