I am a California renter. I recently moved into a new house. After the first month I got a letter from my landlord telling me that from now on I must pay by cashiers check. I did not bounce a check, and this was not included in the rental agreement. The cost to me for the cashiers check is $8. I sent a letter back stating that if this were the case I would deduct it from my rent as I felt it was unfair that I must pay this additional amount. The following month I did just this, as I did not get a response from them. I receive a phone call the day they got the check to tell me that it was not ok, and that all their tenants do this without any problems. I still feel that this is not ok. Is this legal?
