If using an official form, first write the date the document was prepared.Next, write down the balance of the next unused check stub, recording its number as well.From that number, deduct any charges from the bank (i.e. service charges). This will indicate your 'adjusted check stub balance'.Then, write down the balance from your bank statement. Add to this number any deposits which have occured but are not included in your bank statement. Total the amount.After this, subtract the total amount of checks written that are not on your bank statement from the previous total.This number is called your 'adjusted bank balance' and should equal your adjusted check stub balance.
