Landlord Tenant

My boyfriend and I have been living together for about 5 to 6 years. I bought a log house with 10 acres with the understanding that he would sell his house and then split the payments on the log house exactly. I have bought all log tools needed for the property, including a John Deere tractor for $4,500.00 to fix a well pump. He has given me a couple hundred dollars occasionally through the years and once gave me $800.00 for a mortgage payment. My mortgage is over $2,400.00. I became medically disabled with chronic back sciatica and am on major narcotics for pain. What do I need to do legally to have him move out of my house so I can have a paying renter in the 4th bedroom and rent out other acreage. Do I need him to fill out a special form, give him 30 days written notice, or what?

My tenants are not at the property and no one has been at the property since November. Can I change the locks on the property and put their stuff out.

I rented a room from a lady and paid the rent in advance. Six days before the end of the month, she tried to change the locks. She has now given me a three day notice to quit. What are my rights?

Does a life tenancy lease entitle tenants to homestead rights?

Is a wife liable for a lease that was signed only by her deceased husband?
