My boyfriend and I are new roomates (Oct. 2009) with a couple that is renting a house. We did not sign a lease with them or the landlord and our verbal agreement moving in was to pay half of the rent twice a month (every two weeks, no specific dates due to me not being paid on same date each month). This was done for Oct. and Nov. with no problems. At the end of Nov. the they asked us to pay the full amount all at once, but did not specify a date this had to be paid on. On Dec. 2nd they sent us a 3 day pay or quit notice. Can they do this?
