I have been hired as a consultant to assist with various matters in 3 different factories. One of them them they own. The other they are leasing with an option to purchase, and the third one they are paying a monthly payment for the option of purchasing the property. These properties are in Oregon, Colorado, and Wyoming Can I file liens on these? I have a written contract that states I will provide services and will be pain within 5 days of the end of the month........I have not been pain in 5 months and the principal in my contract is not returning calls or messages. Thank You
