Identify the incorrect journal entry related to Revaluation of Assets and Liabilities of a firm.

When revaluing assets and liabilities during admission, retirement, or dissolution of a partnership, proper accounting treatment requires understanding the impact on the firm's financial position.

Entry 1 is correct: When an asset's value increases, the asset account is debited (increases) and Revaluation A/c is credited (represents a gain for the firm).

Entry 2 is correct: When an asset's value decreases, Revaluation A/c is debited (represents a loss) and the asset account is credited (reduces the asset).

Entry 3 is correct: When a liability increases, it represents a loss for the firm. Revaluation A/c is debited (loss) and the liability account is credited (increases the liability).

Entry 4 is incorrect: When bringing an unrecorded liability into books, it means recognizing a liability that was previously not recorded. This is a loss for the firm since the firm owes more than what was shown in books.

The correct entry should be:

Revaluation A/c                    Dr.
     To Liability A/c

The given entry debits the Liability account, which would reduce the liability - exactly the opposite of what needs to be done. An unrecorded liability must be credited to the liability account to bring it into existence in the books, while the corresponding debit goes to Revaluation A/c as it represents a loss.
