Is there any way of proving that friends / family members owe you money or that your owe them money? Can it ibe made legal? It's to help my partner to deal with some of his debts, by owing it to friends / family / me at interest free rate. Just discovered he's been hiding just short of �10,000 in debt from me. We are trying to switich his cards, but his income is not high enough and his debts too high to switch to better accounts.
