Researching the bases of "registration of documents", clarifying the Jurisprudential
legitimacy of "registration fee" based on the four proofs (the Quran, tradition, reason,
and consensus), reviewing the orgination and devlopment of "registration of documents"
and the process of the approval of various registration regulations, and criticizing the
existing officicallaw and the documented articles concerning "registrtion fee", the present
article proves that despite the acceptence of the cost of transactions as the basis of the
"registration fee" in official documents on the part of legislative system, the offices ask
for this fee out of the amount additional to what is registered in the document, however
great and legally excused this amount may be. The article comes to an end with a
reference to the spoiled rights of the two contracting parties and some negative
side-effects of this process.
