Do you have a “Whisper Letter”?

As women accumulate wealth, their focus often turns to their children; how can I help them and how will my money support them when I am gone. It’s easy to assume they will use it in ways that will better their lives and provide the security we want for them, but this can be “wishful” thinking. For more affluent people, trust is often an effective way to control distribution and even put stipulations on how the money can be used, yet this doesn’t always convey our wishes and desires. A “Whisper Letter” is written before your passing, and communicates to your children what your hope is for this money you are leaving behind. It’s not designed to control but to encourage your children to be more thoughtful in how they use this money. You might encourage tithing or investing; you may inspire them to save more or even to splurge a little bit. Giving your children some gentle guidance by using a Whisper Letter can provide both parties some guidance.
