A lot depends on her needs, and her ability to continue to work. This is a very personal situation that needs some study. For sure, you will want advice from a fee-only financial advisor who is also a FIDUCIARY — someone who does not sell products and promises to put your interests first. I consistently recommend the carefully selected advisors who fill this description at www.Wealthramp.com. For the time being, when you get the check just put it in a money market deposit account at your bank. There is no rush to invest it at this juncture of the market. And a good advisor will look at all her needs, and her current situation and help to make a sensible plan.
