The fiancee' to my son just passed away. They've been living together for the past 2-3 years. Planned to get married next year.They purched a new home jointly 3 months ago. No will had been drawn up between them. There are many personal items purched between them. The fiancee's family are now wanting some,if not all of these items. The mother feels because she was named beneficiary on her daughter's life insurance, and is next of kin, she has the rights to anything her daughter owned, whither given to her or owned prior to the engagement. What are the rights of my son, the fiance', in this matter?
