I am currently only accepting new estate settlement projects if I drafted the deceased person's will or living trust.

In 2016 the IRS released proposed regulations to the Section 2704 valuation rules, which would end the longtime practice of discounting the fair market value of closely-held business entities for gift and estate tax purposes.  But President Trump's January 20 freeze on all pending regulations put a halt to that.  While possible the Trump administration chooses to revise the regulations, I find it more likely that the administration will abandon the proposed regulations altogether.  This would avoid the loss of a major benefit of using family limited liability companies for estate planning.
