Provisional application may continue after the treaty enters into force with respect to a state applying the treaty on an interim basis until it is ratified. Provisional application ends when a state notifies the other states to which the treaty is applied on an interim basis of its intention not to become a party to the treaty. The increasing application of provisional enforcement clauses in contracts is a consequence of the need to implement contractual obligations before formal ratification/accession of a treaty by a state. The obligations related to provisional application are assumed by deliberate voluntary action by the State, in accordance with its national legal framework. After a contract is concluded, written documents that provide formal proof of the agreement to be concluded, as well as reservations and declarations, are placed under the tutelage of a custodian. Unless the treaty is otherwise stated, the tabling of the instruments of ratification, acceptance, approval or accession gives the consent of a treaty-bound state. In the case of contracts with a small number of parties, the custodian is usually the state government in the territory from which the contract was signed. Sometimes different states are chosen as custodians. Multilateral treaties generally designate an international organization or the Secretary-General of the United Nations as custodian. The custodian must accept all communications and documents relating to the contract, verify that all the formal conditions are met, file them, register the contract and communicate to the relevant legal acts to the parties concerned. The Council of Europe conventions are prepared and negotiated within the institutional framework of the Council of Europe.
The negotiations resulted in a decision by the Committee of Ministers to adopt the final text of the proposed treaty. It is then agreed to open the treaty to signature by the Member States of the Council and, if necessary, by the other states or organisations that have participated in its development. A reservation is a declaration by a state that it purports to exclude or alter the legal effect of certain provisions of the treaty in their application to that state. A reservation allows a state to accept a multilateral treaty as a whole by giving it the option of not applying certain provisions to which it does not want to comply. Reservations can be made when the contract is signed, ratified, accepted, approved or adherented. Reservations must not be incompatible with the purpose and purpose of the treaty. In addition, a treaty could prohibit reserves or allow only certain reserves. From 1778 to 1871, the U.S. government entered into more than 500 contracts with Indian tribes;  All of these contracts were violated in one way or another by the United States government, while several contracts were violated or violated by Indian tribes.  However, under U.S.
law, offences committed by a party do not necessarily annihilate treaties; Some treaties still have legal effects, and Indians and First Nations peoples are still fighting in federal courts and the United Nations for their contractual rights.   The term “amendment” refers to the modification of certain provisions of the treaty only between certain contracting parties, while for the other contracting parties, the original provisions of the treaty remain applicable. If the treaty amendments are changed, they are only admissible if the amendments do not affect the rights or obligations of the other contracting parties and do not contrane the purpose and purpose of the treaty. The term “authentication” refers to the procedure by which the text of a contract is defined as binding and final. Once a treaty is authenticated, states cannot unilaterally change their provisions. If states that have negotiated a particular contract do not agree on specific authentication procedures, a contract is generally authenticated by signature, ad referendum signature or by paraphification by the representatives of those states.
