She currently has a will that would leave all of her assets to her two minor sons, when she passes away. The will was written before her sons were born.
Spears would now like to change the distributions from her will, so a trust provides staggered distributions to her sons. Instead of giving her children everything immediately, the trust would distribute her assets over time, as they reach certain landmark ages.
TMZ reported this story in "Britney Spears I Need a New Will to Protect My Kids."
The important thing to learn from Spears is that when circumstances changed, she revisited her estate plan to adapt it to those circumstances.
Before she had children, her current will might have made sense as her best estate planning option. However, with minor children, a trust to protect the distributions under her will became the better option.
This is something that everyone should do. Changed circumstances require changes in estate plans.
You probably should not take Britney Spears' as a positive example for other financial decisions. However, in this case, you absolutely should.
