Proper Books of Account Law and Legal Definition

Proper books of account are such books as will enable another merchant, a creditor of the insolvent for instance, to see the financial status of his debtors. The books of account of a merchant or trader kept in such a manner, that any competent person, by an examination of them, could ascertain and determine the real condition of his affairs; and if they be so kept, though imperfect, inartistic, and inaccurate in unimportant particulars, they will be treated as proper books of account.
