Lease Agreement signed under false pretense and possible forgery

False pretense and forgery are very difficult and expense "defenses" to an eviction lawsuit and in most such cases inconsistent with such claims. By example, if the LL sues for eviction to recover possession of the property, arguing that the rental agreement is forged, simply reinforces that the tenant likely has no right to stay in the property, and should be evicted on demand. You will need to retain, not consult with, a lawyer ASAP as eviction cases have very strict and specific time frames for response that can result in eviciton simply because th tenant does not follow the rules.
