You would know about it if you had been evicted.
if you have lease, you cannot be evicted without an eviction notice,or notice to quit. If you do not have a lease you will need to deal with legal authorities on this.
A sample letter of eviction notice for nonpayment should have matching addresses, and names of the parties as those of the tenants, to be admissible in a court of law.
I used to be a property manager in Iowa and Illinois, so depending on the state laws it varies. But these two states if it is due to non-payment, then they have to notify you with a notorized letter, then they have to file at the local courthouse for evition. Once that is done then there is a court date and if you don't show up then usually the judge will give the landlord immediate possession. I know that even if you don't have a lease, the landlord still legally has to go through the eviction process. If its for something other then non-payment then there is usually some sort of 30-day notice given to the tenant, then the eviction process at the courthouse again. If this doesn't help you then you can always call your local courthouse. One more thing, legally after the whole process the items are suppose to be sat out on the curb for anyone to take or for trash and that gives the tenant a very short time to collect their belongings. Usually for that the landlord is suppose to be escorted by the sheriff's dept.
