I don't have any real estate, only cash that is less 15,000 which my mom's name is also on my bank account. The only thing I can think of is I have a 401K and life insurance policy that I've designated to my mom, sister and brother as beneficiary. I may have a residual paycheck from my company and life insurance that my company give if I were to die. Would my family have a problem with my 401K and life insurance proceed from my company if I die and I don't have a will or living trust? Will I need to have those in place?
