i know this is an odd question to ask but dont know who else to ask and im quite isolated. my father gave me a pendant before he died and told me to where it which i do, his mother gave it to him when he was a boy. it has no real value just sentimental. another family member says she has more right to it and is going to rip it from my neck when she gets the chance. is there anything i can do it make it legally mine?
