Nearly half of us admit to having a secret money stash that close family and friends don't know about.
It's mainly in bank accounts, bonds, stocks and shares - but some even put it in hiding places around the house.
A poll - by a British law firm - also discovered one in 10 hide savings in case their nearest and dearest tried to spend it.
Nearly third claimed they just never got around to telling loved ones about the money they'd squirrelled away, while almost 40% of those surveyed said it was their money to do what they wanted with!
