No, there is no requirement that creditors remove the negative notations--though they are welcome to. The issue is purely whether the notations are or were accurate; if they were--for example, if they honestly and correctly reflected defaults, late payments, etc. which had occured--then the creditor is under no obligation to remove them. The credit report should also reflect any subsequent events which help, justify, or moderate them--for example, if you disputed the amount of a debt or your liability, that should be included--and of course the credit report should also reflect the bankruptcy filing itself; but fundamentally, accurate information does not need to be removed, even if a bankruptcy later discharges a debt.
