The oldest Jenner sister will be 18 in less than two months, and aside from being able to buy lottery tickets and such (not that she needs them,) she also has something else to look forward to: a six-figure trust fund. All child stars in California have 15% of their earnings placed into a trust, known as a Coogan’s Trust, that their parents and business managers cannot access. So on November 3rd, more than $300k will be all Kendall’s. Now that’s a gift!
