"Unfortunately, these innovations, user choices, and privacy concerns are ignored by the 'give everything to the fiduciary' nature of the law," the letter said.
Delaware's law also conflicts with the federal Electronic Privacy Communications Act, which prevents companies from sharing the contents of communications in civil court proceedings unless they first obtain consent from the subscriber or sender, the letter said.
The legislation has yet to make its way into other states besides Delaware, but that doesn't mean its reach is limited. People don't have to live in Delaware for its law to apply.
The law applies depending on which state governs the fiduciary relationship, said Kelly Bachman, press secretary for Delaware Governor Markell.
That means it would apply if the person's will is created under Delaware law, or if someone is given power of attorney under Delaware law, she said.
