You need to hire a lawyer. If you had a lease with your deceased parents and if it was in writing, it might be binding upon the estate and therefore your sister who you say is named executrix would have to abide by it. Assuming there was a court action appointing your sister as executrix, the appropriate place to bring this action is in that court. You can not do this without a lawyer.
