Preliminary notes:
The Liechtenstein government has released a good information sheet on the most important changes between the existing and the new foundation law becoming effective as at 1 April 2009. As from 1 April 2009 on, there will be two laws living together which might make it not as easy as before for the international investors and the trustees in Liechtenstein. Furthermore, some of the new articles will automatically apply to the "old style" foundations as well, above all the rights of the beneficiaries to receive information from the foundation board.
One of the most significant positive changes regarding the asset protection is the fact that the Liechtenstein law will restrict rights to attack foundations on the basis of foreign forced heirship rights to two years. This will apply to the new foundations or gifts after the relevant date and will have a positive effect as the court does NO LONGER only look at the settlor's nationality or domicile in order to decide how long the period to attack can be, which can be up to 30 years in certain cases. So if the foundation deed and the endowment/gift documents are well drafted, the period can be reduced to 2 years.
The rights of beneficiaries to get full information on the foundation is sometimes contrary to the founder/settlor's will. The new law will surely enhance such legitimate rights, however also here some legitimate finetuning is possible to address the settlor's concern about too excessive investigations by successor beneficiaries.
Below the wording published by the government:
The following summarizes the most important differences between the old and the new law governing Liechtenstein foundations. However, this summary only illuminates some of the most important points and should not be considered exhaustive.
- As under the old law, the founder can in principle freely
      choose the purpose of the foundation. The founder may pursue
      charitable or non-charitable purposes and, for instance,
      establish the foundation to provide for his or her family
      members. As under the old law, unconditional distributions
      will continue to be possible.
 - The founder must henceforth lay down the purpose of the
      foundation at least in outline and determine the circle of
      beneficiaries in the foundation documents. The founder may
      not delegate this task to the foundation board. This is
      intended to strengthen the founder's responsibility
      for his or her own foundation.
 - Where foundations are formed through professional
      trustees, the trustor ("beneficial founder") will
      continue to be deemed the founder in a legal sense. All
      rights reserved by the founder (e.g. right of amendment or
      revocation) are vested in the founder on a personal basis.
      The founder's rights cannot be transferred or
      bequeathed. This does not entail any dilution of
      confidentiality, since the identity of the founder does not
      have to be disclosed externally. In external relations, the
      founder can exercise his or her rights through the
      professional trustee.
 - Charitable foundations are henceforth subject to
      supervision by a newly established Foundation Supervisory
      Authority. Charitable foundations must also establish an
      auditor responsible for annual verification that the
      foundation assets are managed with care and in conformity
      with the foundation purpose.
 - Non-charitable foundations, especially family
      foundations, are as a rule not subject to supervision by the
      Foundation Supervisory Authority. To monitor the foundation
      board, the beneficiaries have rights of disclosure and
      information at their disposal. Alternatively, however, the
      founder may also restrict or exclude these rights of the
      beneficiaries by establishing an internal controlling body,
      such as an auditor, or by voluntarily placing the foundation
      under supervision by the Foundation Supervisory
      Authority.
 - Charitable foundations must be entered into the Public
      Registry.
 - Non-charitable foundations, especially family
      foundations, are not subject to entry into the Public
      Registry. Unlike under the old law, the foundation deed now
      no longer needs to be presented to the Office of Land and
      Public Registration for review. Instead, a notice of
      formation by the foundation board suffices, the content of
      which must be confirmed by an appropriate professional
      (especially a lawyer or a professional trustee).
 - The organizational structure of the foundation remains
      flexible. As a rule, the foundation need only have a
      foundation board to manage the foundation assets. To ensure
      realization of the founder's intent even more
      effectively, the foundation board must have at least two
      members (corresponding to current widespread practice). Only
      charitable foundations need establish an auditor as a second
      governing body. Beyond this, the founder is free to create or
      refrain from creating other governing bodies.
 - As under the old law, the founder may belong to the
      foundation board and/or be a beneficiary himself or
      herself.
 - Under the old law governing foundations, adjudication
      turned out to be the engine of further development and
      specification of the legal situation. The new foundation law
      incorporates numerous of the ideas developed by the courts,
      thus ensuring legal clarity and certainty.
