<prompt> Human: As the title says, I had an estranged paternal grandfather who passed away 3 weeks ago. I ofcourse knew he was a fairly wealthy man but I never expected hed leave me anything but it turns out I was wrong. The total of everything comes up to just over 2 million primarily in the form of stocks and cash5050. In addition Ive also received his holiday home in Florida. All of this will come into my possession within the next month.I would like to use part of this money to create some kind of retirement account for my mom. Im willing to spend a maximum of 500k on it. Shes a 57 year old high school teacher and shes in perfect health. Shes going to retire in about 3 years so I want to start on it now and surprise her with it when she retires. She knows about the inheritance and the only thing I told her was that Id pay off her house about 70k which made her expretemly happy. Shes helped me a lot over the years so she deserves every dime. I imagine if Im lucky that shell live another 30-40 years so Im looking for advice on how to provide for her throughout the remainder of her life. I dont want to just hand her the money as a lumpsum because I dont think shed be very good with it and besides that Ill sleep better knowing shes getting some kind of fixed salary every month after she retires. An ideal solution would be one where she receives a fixed amount every month.Thanks in advance  <response>: Go talk to an estate planning lawyer.
