A father and son are to become a married couple after a 50-year relationship.

But before you start to worry about some weird incest thing, they aren’t actually biologically related.

In fact, Bill Novak and Norman MacArthur used a technicality to gain the rights they wanted when they moved to a part of the U.S. that didn’t recognise same-sex partnerships.

They registered as domestic partners in New York in 1994 before moving to Pennsylvania.

Norman told Patch: ‘We were told at that time “hell would freeze over before Pennsylvania approves same sex marriage”.’

And so Novak adopted MacArthur in 2000.

It turns out that it must be quite cold in hell right now because Pennsylvania has had to allow same-sex marriage.

So they broke off the adoption, a practice that had been used by many same-sex couples in the state for some time, and this summer they will officially get married.

Norman added: ‘We are ecstatic beyond relief. I feel an enormous sense of not only relief but freedom that we can finally do something in Pennsylvania that I’ve been dreaming of for years.’
