My daughter is 17 years old. While in high school she took a guitar class and with the permission of my parents was allowed to use a guitar that belonged to my deceased brother. When the guitar class was completed for the semester she took it upon herself to give away the guitar, which did not belong to her, to a classmate at school. When we contacted the classmate he informed us that he had put $60.00 into repairs and if we paid him for the repairs he would in turn give us the guitar. The story has now changed and he is stating that in actuality he has put in at least $200.00 into the repairs for the guitar and also refuses to give back the guitar. If he indeed used $200.00 of his money to repair the guitar I have no problem paying but he also refuses to show proof of the expenses incurred for repairs. I have the serial number of the guitar and would like your opinion in knowing whether or not this is a lost cost or would I stand a chance in civil court? Thank you for you time.
