How can I get my mother in law to move out?

Asked by Kkj1234 (18) November 9th, 2013 from iPhone

Me and my husband have 4 children and a very small house. His mom and 18yr old sister moved in, mom became ill and moved in due to a income cut. But she still got a monthly income. The mom and sister is driving me crazy, and I feel over violated in my space. She has been here 9 months and has given us no money. She has not even saved her money nor given us a date to leave! I’m so stressed and want to get back to the way things use to be.
