I have an inheritance of 5M usd debt, I tried to cover it up else my 78 yo old man would get in jail.

If he passes away, the remaining $2m debt will be accounted as my debt, legitimated by court law based on the national law.

The law in my country put assets and debts as part of inheritance, so if someone fucks up very badly, their descendant must denounce, disavow and cut all legal ties with their parents, else the debt will kill them.
