Tenant late rent payment LI NY
I have a tenant that has been renting for 12 years but has no lease and for the last 3 months he has been playing games with rent payment. He has not paid his January rent and it is now the end of the month. I called he said its in the mail. The apt is in LI NY and I live in Pa. I had to evict his sister inlaw and since then he has been late and had an attitude. I pay all utilities except electric... they are fuel oil , gas for cooking , water and sewage. I want to send him a vacate notice is there a legal form or just a letter. Also can I turn off the water and gas for cooking. I can't turn off heat due to freezing and I am sure that would probably be against the law. Thank you for your advice. Is a month notice enough or can I give less with no lease?
