Summarise a Complicated Family Financial Arrangement

Money has moved around the family for years and nobody is sure who owes what to whom. This maps every flow, who gave what, and in what form, so there is one clear picture before anyone tries to resolve it. For families with a money situation that has grown murky and needs untangling without an argument breaking out first.
