Father and Son want to marry , seeking legal permissions

The legalization of same-sex marriage has given way to a new problem for a Pennsylvania couple, who technically are father and son.

Before states across the country began striking down bans on same-sex marriage and the Supreme Court ultimately decided the issue nationwide, some gay couples used adoption laws as a way to gain legal recognition as a family, and the related benefits such as inheritance and hospital visitation rights.

Nino Esposito, a retired teacher, adopted his partner Roland "Drew" Bosee, a former freelance and technical writer, in 2012, after more than 40 years of being a couple.

Now, they're trying to undo the adoption to get married and a state trial court judge has rejected their request, saying his ability to annul adoptions is generally limited to instances of fraud.

"We never thought we'd see the day" that same-sex marriage would be legal in Pennsylvania, Esposito, 78, told CNN in a telephone interview.
