My girlfriend's mom purchased a house that my girlfriend then rented. Her mom wanted some framing around water heater, etc done in basement and also wanted a deck built. Many text messages to prove that she asked for these things but no contract. Her mom was also there in person for some of the deck construction. Payment was never discussed. Her mother purchased most deck materials but not all. Now her mom suddenly wants to sell the house and has already had realtor pictures taken. Will not respond to anything regarding payment for any materials or labor. I did all the work myself. Also not sure if a permit was ever actually filed. Do I have any lein rights?
