# What to do with a large cash windfall (without losing it)

Source: https://wealthscout.app/updates/what-to-do-with-large-cash-windfall

The first rule of a large cash windfall is to do nothing for 6 to 12 months. Park the funds in a safe account, hire a fee-only fiduciary advisor and a tax attorney, and strictly cap any gifts to family and friends. When you are ready to invest, use broad, low-cost index funds to preserve the wealth rather than speculative individual bets.

## Takeaways

- The first step of managing a windfall is doing absolutely nothing for 6 to 12 months.
- The 'Friends and Family Trap' destroys more windfalls than bad investments do.
- Investing the money should follow the 'Casino' analogy: buy the whole casino via index funds rather than betting on individual tables.

**Scope.** Tax implications on windfalls vary wildly depending on whether the money came from an inheritance, lottery, or business sale. Always consult a tax attorney before moving or gifting any of the funds.
