My question involves an eviction in the state of: Oklahoma
I have a, what used to be, friend living with me in my house, I own the property. She pays rent but we did not sign a formal lease agreement nor are there receipts of rent paid. She is an adult but under 21 & has been drinking with her friends in my house. I am over 21 & told her that it can not happen anymore & stated the reason that I can be held liable & serve 5 years in prison for a felony. She said I was being stupid (I thought I was being smart, go figure) & got upset about it. Seems she would rather put her selfish desire to drink over a person's interest & wishes. She then made a low blow comment about my upcoming marriage. It is safe to say our friendship is now over & that she needs to go.
My fiancee & I did some research into the subject & read that Oklahoma court does not recognize verbal lease agreements without a witness involved. Neither of us have been able to find a clear answer (50/50 both ways) on whether I need to provide an official 30 day eviction notice or if I can have her evicted immediately for breaking the law. I do not want to go to jail for her selfish desires.
I have looked at the Oklahoma ABLE committee regulations on consumption & at the Social Host Law. I have found answers stating the law about minors under 21 drinking, & as mentioned earlier, property owner felony for under age drinking on owned property.
Thanks in advance for any advice.
