That, according to my insurer, is a problem which one cannot do anything about.
Can you not have some sort of contract drawn up? For example, I own my house - My wife is no where on the mortgage or deeds or anything (for the simple fact that when I bought it we were not married). Rather than pay to get her on the mortgage we saw a solicitor who drew up some sort of contact which basically said "I own the house, but it was bought for us both, so if I die then the house will get passed to mrs B"....
can't the same be done with aeroplanes - "XYZ Corp owns the aeroplane on behalf of Mr B. If the company should fold or die then the aeroplane still belongs to Mr B" ?
My wife has a US passport so anyone wants to give her their aeroplane, then that is fine! No charge, just free use
