My question involves a roommate in the State of: Washington
4 of us signed a lease to live together and the lease says tenants agree to pay for all utilities and services provided to the house. So I put the utilities in my name and all the roommates paid me 1/4 of utilities each month. I recently moved out of the house and found someone to take over my lease, however, there was still the final utilities bill coming to me. I received the bill and 2 of the roommates said they would give me a check for their portion of the utilities but the last roommate won't write me a check for her portion of the utilities. The landlords say that its my problem and that they can't do anything about it. I'm not sure what to do. I don't have any written piece of paper saying everyone will give me money however it was implied in the lease that we all have to pay for utilities. I got payment from all 3 roommates every month I lived there but now that I moved out the last roommate I think feels that theres no way I can collect payment from her.
