From my experience it can take longer than 3 months. So this is still possible. John K told he has dead-man's switch in place:
Unless you know the lawyer how can you know this info is right. Someone who has disappeared said it was all ok and promised there was some backup system in place, sounds great but we would actually need the lawyer details.
Of course the lawyer thing could be a scam also but at least its a further person and trail to follow, seems there is nothing still
