It is good to see that cryonics is now sufficiently widely known that business magazines are willing to write articles on the financial engineering and legal explorations associated with establishing a successful cryopreservation: "Financial planning, like most disciplines, generally relies on the assumption that the dead will remain that way. Some people, however, are not as willing to accept this premise. Cryonicists believe science will eventually give us the ability to reanimate the dead. In preparation for this possibility, they elect to have their bodies, or sometimes merely their heads, stored in extreme low temperatures so that, when the time comes, they can be restored to life. Some anticipate a future in which their bodies will be thawed and cured of their ailments, while others see the process as akin to data storage, preserving the organic record of their thoughts and memories until these can be downloaded onto some new medium. ... the legal and financial questions surrounding cryonics require serious believers to make plans in the present, before they start their hiatus. Since cryonics remains well outside the mainstream, most end-of-life matters have yet to be thought through as temporary-suspension-of-life concerns. Ordinarily, at death, social security numbers are cancelled and made public, and citizenship privileges such as voting are revoked (at least in most jurisdictions). What would the temporarily dead need to do to put their legal status on ice along with their bodies?" If you want a serious consideration of the details, you might look at some of Rudi Hoffman's articles on cryonics and financial planning.
