Not likely? Are you an idiot? You liquidate and buy tbills with the trust money. On your way home from vegas do you stick the payout slip in your wallet or do you pay a visit to the cashier before checking out?
What I am saying is that there is no requirement to sell the stock to have cash for inheritance (if that is the reason). If anything, it's a poor choice for estate planning purposes because capital gains taxes would have to be paid now and then as cash/tbills it would then be subject to estate taxes when you check out. The stock can just as easily be given as the inheritance directly, and capital gains taxes would avoided.
So, do you pay a visit to the cashier before checking out, or just give the payout slip as the inheritance which can be cashed out by the folks you leave it for and avoid having a chunk taken out and double taxation?
