Evelyn Bennett, a 67-year-old retiree, has a complex estate valued at approximately $12 million. Her assets include a diversified investment portfolio, a primary residence worth $3 million, and a beach house valued at $2 million. Evelyn wishes to ensure an equitable distribution of her assets to her three children: Sarah, Mark, and Anna. Each child has unique financial situations—Sarah is financially stable, Mark is struggling due to a recent job loss, and Anna is starting a family and is in need of financial support. Evelyn is also concerned about minimizing estate taxes and providing liquidity for her beneficiaries to cover potential expenses related to estate settlement. In light of these considerations, which estate planning strategy would be most suitable for Evelyn to address her objectives?
