Document discrepancy determination and mitigation can include marking a fragment of a first document and a corresponding fragment of a second document in response to determining a dependency between the first document and the second document. A discrepancy probability with respect to the first document and the second document can be identified based on a discrepancy measure, which can be determined by comparing the marking of the fragment of the first document and the marking of the corresponding fragment of the second document. One or more discrepancy mitigation procedures can be initiated in response to the discrepancy measure exceeding a predetermined threshold.
