What "technicality"? Does he own the house? Have they been renting it for 52 years? If so, from whom?

It says he wasn't on the original occupancy as he wasn't born when the paperwork was originally handled but was one when the building was finished and moved in. He claims when he tried to get on it in the past via his mother the coop stalled until she was dead.
Of course it also happens to other people to, naturally, but if those kind of things start happening en masse...
Is this some sort of rent-control problem? Where his parents lived in a rent-controlled apartment and passed it down to him improperly? (I have no idea how rent-control buildings in NYC work, this is the only that makes any sense without details)
