Can i sue my landlord?

i was living in a low income apartment and never missed rent or any other bills but they evicted me for allowing my daughter dad to stay the weekend for christmas and not telling them....anyway they gave me a eviction notice and had the police there and gave me the paper...the paper said i was being evicted for the following reason and that i had to be moved out by feb 28th by midnight and any stuff left in the apartment would be sold....and today which is the 12th they changed my locks and selling my stuff and i have about roughly 10000 dollars worth of stuff there mostly baby furniture anyway if they procede to sell the stuff can i sue them cause its only the 12th
