Suppose you are the judge, and a case is presented before you where a tenant is facing eviction. The landlord has been in constant contact with the tenant and is able to supply the texts and notes to the tenant. However, the tenant agrees that the landlord did contact him, but the tenant claims there was not sufficient notice. The landlord is able to show months of texts and notes begging for the rent from the tenant. What are the legal considerations you would evaluate to determine the claims of the tenant and the landlord? In whose favor would you rule, and why? Be sure to support your legal analysis.
