Doctors have given John Stone-Hoskins a very grim prognosis.

They say the Texas man, who has cancer, he’s got approximately just two months to live – at the most.

Stone-Hoskins is using some of that time to fight for something very important to him: he wants his late husband’s death certificate to be revised so that it will reflect their 2014 marriage which took place in New Mexico.

James Stone committed suicide in January, more than six months before the US Supreme Court ruled that marriages between same-sex couples are legal nationwide. His husband was not listed on the death certificate as the surviving spouse.

San Antonio-based lawyer Neel Lane Jr. is asking the Texas Department of State Health Services to revise the death certificate as soon as possible, according to Texas Lawyer.

Lane wrote in an email to the agency that Stone-Hoskins ‘cannot wait’ because he is on ‘borrowed time.’

Lane said his client has submitted everything necessary to issue the new death certificate, but the agency has not agreed to do so.

‘His doctors expect him to live another 45–60 days,’ he wrote. ‘As you probably know, such projections are unreliable, and he may die at any time.’
