Five weeks ago, on my way from France to the United States, I decide to propose to my girlfriend of 9 years. Her and I have been living together for the past eight years of our nine years relationship. As we touchdown to picked up our bags, I got on my knees and proposed. Needless to say, we were both crying in a rainy day in San Diego Inter National Airport arrivals baggage claim. After she accepted my proposal, we both drove to my mother's house in North County to break the news to her. My mother was very happy, and she offered us the family ring. The ring has been in our family for past seven generation and has been passed from one matriarch to another via written contract. In that handwritten contact, the receiver must, first, accept the responsibility of passing on the ring to the next generation, second, stay married, and third, return the ring if divorced or if decided not to marry the into the family. My mother took a piece of paper and rewrote the seven generational contacts. My fianc gracefully accepted the offer they both signed the paper and we all left for diner that day. A week later, my fianc wanted to move out, break the engagement and keep the ring as a gift. Sited the common-law marriage in the State of California. Do I have a valid and enforceable contract to recover my family ring from her?, Did we reached an agreement, wash there consideration present, was agreement between my mother and my ex-fianc legal, did my mom and my ex-fianc had the capacity to make a contract and finally was the agreement in the proper form?
