The legality of intergovernmental agreements (IGG) has been questioned on the grounds that any agreement between governments that binds each government is essentially a treaty. Because the U.S. Constitution does not allow the executive branch to unilaterally implement treaties without Senate approval, many argue that IGAs have no basis in the U.S. Constitution.  IGAAs were not described or provided for in FATCA legislation, but were designed and implemented retrospectively when it became clear that fatca would fail without them.  In English law, the exchange of contracts is the final step in the purchase of a home, which takes place after a lawyer has done all the necessary research and the terms of the contract have been agreed. Once each party has signed the contracts and they have been exchanged, they are binding. This agreement, published in April 2002, is not a binding instrument but contains two model bilateral agreements. A large number of bilateral agreements were based on this agreement (see below).
In June 2015, the OECD`s Committee on Fiscal Affairs (CFA) approved a model protocol to the agreement. The standard protocol can be used by courts if they wish to extend the scope of their existing AERFI to the automatic and/or spontaneous exchange of information. This exchange of information on request was supplemented by an automatic procedure on 29 October 2014.  The automatic process should be based on a common reporting standard. Contracts include a completion date, which is the date on which the property is purchased by the buyer. When exchanging contracts, the required deposit must be paid and arrangements must be made for the insurance of the building so that the property is insured from that day. As a general rule, the current insurer will cover this new property until the completion date without an increase in premiums. This is a system that only occurs under English law, and the exchange of contracts can take place several weeks or months after the basic agreement of an offer to sell. This is in contrast to most countries where home sales become legally binding very quickly.  Tax Information Exchange Agreements (ERAAs) provide for the exchange of information upon request in the context of a criminal or civil tax investigation or a specific civil tax case.
 A TIEA model has been developed by the OECD Global Forum Working Group on Effective Exchange of Information. In this way, courts can then base a bilateral agreement on the competent authority on an AERR for the purpose of introducing the automatic exchange of information in accordance with the common reporting standard or the automatic exchange of country-specific reports, in particular in cases where an automatic exchange of information is not (yet) possible under a relevant multilateral agreement of the competent authority. The purpose of this Agreement is to promote international cooperation in tax matters through the exchange of information. It was developed by the OECD Global Forum Working Group on Effective Exchange of Information. Legal systems may also choose to use the wording of the articles of the Model Protocol if they wish to include the provisions on the automatic and spontaneous exchange of information in a new AERT. The agreement is the result of the OECD`s development to combat harmful tax practices. The lack of an effective exchange of information is one of the key criteria for determining harmful tax practices. The agreement is the standard for an effective exchange of information in line with the OECD`s harmful tax practices initiative.

It is available in English and French as well as Spanish, German, Italian, Japanese, Korean and Turkish.
