Is the failure to complete the purchase of the apartment due to a lack of previous contract sequencing considered proof that I have wronged the seller?

What the questioner did is not an injustice, for it is his right to document his ownership through recognized methods, and his request must be granted because documenting transactions is a legitimate matter due to people's need for it, and it is a right for whoever requests it. Even if it is said that witnessing is not obligatory, either party has the right to request it from the other. Therefore, the owner of the apartment is more deserving of the description of injustice due to his violation of the confirmed agreement regarding the necessity of bringing all previous contracts.
