(note...she did not offer to pay rent) To proceed with an unlawful detainer I do not need to serve any notice but proceed directly to file.

In some jurisdictions, when a lease expires, your tenant becomes M2M by default - CA is a tenant friendly state.As a matter of fact, if you ask a tenant to leave without an unlawful detainer - assuming one is legally warranted - they are entitled to a relocation fee.https://hcidla.lacity.org/syst...To your success!

The attorney said that if I were to move his belongings out of the property or change the locks without going through all of the legal steps it would be an unlawful eviction - even though he had never submitted an application and wasn't on a lease.Obviously this was an extreme and unusual situation. 

The law make it unlawful to discriminate on the bases of race, color, religion, sex, and national origin, disability, and familial status."

Your client had been evicted and if he was on my property and if he was hurt, he was unlawfully trespassing.

If yes, it become appurtenant (attached and part of) to the land.If yes to both, then you have an unlawful detainer matter.

I just got back from court for an unlawful detainer action.

@Michael Haas I'm guessing so because even the landlord tenant act says "You may have heard that it is unlawful to evict someone in the winter but this is not true."

In some municipalities, an unlawful detainer (“i.e. eviction) is still possible to obtain, that being said California state statues AB 1482 and AB 3088 severely limit most landlords abilities to evict tenants, and in most instances only able to evict for “just cause” meaning that the tenant has been a nuisance or has threatened the safety of other tenants at the property.

If a tenant holds over after being properly served legal notice, then filing in court for Unlawful Detainer and proceeding with eviction may indeed be necessary.
