Increases and decreases in Sales'' Comparative Study"

The subject of increase and decrease in sale item after concluding the contract and before delivery is one of the most important subjects as a result of the importance of the sales contract itself, nevertheless, this subject wasn’t studied much despite the importance of the subject and the knowledge of all civil regulations compared to it. In this thesis I studied “Increase and Decrease in the sale item after concluding the contract and before delivery” situation of comparative civil legislations from increase and decrease in the sale showing the extent of agreement between contractors or convention to identify the laws of increase and decrease, explaining the laws mentioned in the legislations of the study subject in this matter in case of agreement absence or exclusion of application of what convention determines, following the comparative analytical approach so to give the researcher an opportunity to cover all the aspects of the study. I discussed the rules mentioned in the comparative legislations in the study subject that focused most of the time on the capability of the sale item of partition, and whether the price of the item was fixed according to the standard unit price of the sale item or according to price of the whole sale item in the shown form in the study. First chapter also showed the rules of increase of the sale item in the comparative laws where I illustrated these rules in the Jordanian civil law and journal of judicial verdicts first, then showed the corruption of the rules in the Egyptian civil law and the Lebanese obligations and contracts law comparing between the later and those shown in the journal and the Jordanian civil law. Chapter two dealt with the decrease in the sale item in the comparative laws following the research plan I followed in the first chapter, where I illustrated those rules in the journal of judicial verdicts and the Jordanian civil law, then presented these laws in the Egyptian civil law and the Lebanese obligations and contracts law analyzing and comparing between the later and those rules mentioned in the journal and the Jordanian civil law.
