1. Natasha and Sven wish to gift use of the lake house to their two children for as long as either child is alive, and then leave the house to a local public charity conservancy group. What sort of arrangement could Natasha and Sven set up, and what would be any tax implications?

Natasha and Sven both have their two grown children as alternate beneficiaries on their retirement accounts. Natashas IRA would be distributed per stirpes. Svens 401(k) would be distributed per capita. What specifically would you tell Natasha and Sven as to what would happen with their retirement accounts if either Raphael or Lucifer pre-deceased them?
