Furthermore, most contracts had many provisos written into them that stipulated the wording of what constituted a crime or breach to ensure that if the buyer broke the agreement made with the buyer during the contract period, it would be recognized that the seller would immediately buy back whatever was sold, just as with a honsengaeshi (a land sale that had the seller buy the land back in such a situation; nenki-uri were also worded in such a way as to have sellers buy back whatever had been sold), and moreover, that the seller's obligations for labor (and the distribution of other assignments) as well as the collateral offered for the sale would be disposed of, and that those possessions which could be sold would be pawned.
また、契約期間中に買主に違約があった場合には売主は本銭返と同じように直ちに買戻しが認められた（本銭弁償文言）をはじめ、売主の課役負担や抵当物件の処理、入質の設定、罪科文言などの多くの条件が契約を記した証文中に記されていた。
