Inheriting Money on UC & PIP

Hi, I always thought that inheriting money was good thing...until I started looking into it.
Is it really true that if someone on UC inherits they get their benefit stopped and can only spend the inheritance at the same rate per month as what the benefit would have been, otherwise they get accused of "intentional deprivation of capital" and have their benefit stopped (if over £16,000) or reduced (if between £6,000 and £16, 000).

That would leave a person no better off if they spent it slowly or worse yet DESTITUTE(after the money ran out) if they spent it too quickly.

Has anyone had this problem do you know where I can find out more.

Citizens advice say they don't know anymore than this, but they did warn that if I pay a solicitor to explain more then the very act of paying solicitors fees in itself would count as "intentional deprivation of capital."

Thanks in advance if any one can shed any light on this.
