notice to quit
In PA. notice to quit are supposed to be mailed CERTIF- IED. Since when did our judicial send police to hand deliver notice to quit. Has the law in PA. changed where polic can take te place of lower courts. ”if tenant breaks any lease, each tenant agrees to give up the right to have a notice to leave, also known as notice to quit. The landlord may file a lawsuit in COURT asking for a COURT ORDER evicting the tenant[s] from the leased property.” The landlord can only evict tenant by court action. Is this the law? If not then what is..?
