Cryonics re-entry strategies What legal hurdles will revived cryonicist need to overcome for reintegration?

Cryonicists, having been declared legally dead and issued a death certificate, will need to overcome this and other hurdles when returning to a civilized future. Marriage is clearly until "death do you part". As we are speaking of civil marriage, the civil declaration of death by certificate will terminate marriage, but not the underlying legal ties as parents and kin to family. Remarriage complicates the social fabric, but not necessarily the legal fabric. Death certificates can be amended. Perhaps a "revival" rider will be added to them to certify that such patients have returned from death? This would be within easier parameters than issuing new birth certificates or creating a whole new class of "rebirth certificates" that would require new forms of record keeping on state and county levels. Coupled with a court order, this seems the easist re-entry point into civil society. Other ideas? P.S. I'm not addressing this question to jackass nay-sayers, so stay away!
