Prince William turns 30 today and will have access to the sizable inheritance left to him by his mother, Princess Diana, who died in a car crash in 1997.

While that isn't exactly a cause for celebration, considering the reason the money is there in the first place, William, with the help of wife Kate Middleton, will put the pounds to good use.

Diana left an estate estimated at close to 13 million pounds for her two sons.

When Diana drew up her will and created a trust for Will and Prince Harry, 27, they were originally able to access the money when they each turned 25, but the executors of her estate changed it to 30 following her death.

The brothers have been receiving interest from the principal sum since they each were 25.
