It's more correctly to say does pandukelana2712's wife/children/siblings/parents etc that has family connection with him is owe the money? I'd say it's yes, but I think his family doesn't know this forum.
But about the legality, their family, spouse or friend have no legal obligation the debt in most cases. It's different case if that person wish to keep asset which isn't fully paid yet or cosigned a loan with the deceased one.
