I am leasing a house in CT and we had a little financial trouble one month and my lease stated that my payment was not considered late if it was paid before the 15th of the month. I sent it out over night on the 10th and the next day day on the 11th I was served with a notice of evicition. Apparently CT law states that if someone is 10 days late the landlord can start precedings. However, If I have a legally executed document that stated the 15th - which takes presidence?
