A non-fiduciary advisor only needs to recommend "suitable" products, which can legally include high-commission funds that benefit the advisor, not you. In 2026, with $84 trillion in generational wealth changing hands and AI tools reshaping who gives advice, knowing whether your advisor is a fiduciary is the single most important question you can ask.
