I sold a 5th RV to a friend who had bad credit, so I let her make the payments to me and I paid the bank. We never did any paper work to show I sold the trailer, but on all the checks she put under the MEMO line... 5ht Wheel payment. She has since moved out of state with the RV and is not making the agreed verbal payments. Can I put a lien on property she owns here in California?
