The trial balance is a worksheet on which you list all your general ledger accounts and their debit or credit balance. It is a tool that is used to alert you to errors in your books. The total debits must equal the total credits. If they don't equal, you know you have an error that must be tracked down.
In a trial balance you list all
Assets
Liabilities
Owners Equity (Stockholders Equity)
Basically you use your accounts from your General Ledger.
