Our lease ended July 30, 2011 and we told here that we weren't sure if we were going to stay here or not. She said that's fine and we can go by month to month till we decide. Now that it's December she did another year lease but dated to back to July 1, 2011. Well I signed it and started putting today's date on it 12/7/2011 and she told me to date for 7/1/2011 so I crossed it. She said it will be complete and finally when my husband signs it. I told him not to though because of the back date. Is it illegal to back date it and can I still do something even though I signed it?
