This general difficulty of municipal laws failure to support trusts is addressed in Article 13, which considers the situation of those who wish to create a trust but can only do so by invoking laws entirely outside their own state. As an application of comity, no forum state is bound to recognise a trust the significant elements of which, except for the choice of the applicable law, the place of administration and the habitual residence of the trustee, are more closely connected with States which do not have the institution of the trust or the category of trust involved. But, because this could be interpreted as an invitation not to validate otherwise perfectly appropriate financial arrangements for deserving beneficiaries, Article 14 provides that the Convention shall not prevent the application of rules of law more favourable to the recognition of trusts. This reflects the positive rules of public policy which require that the validity of a transaction (whether commercial or not) be upheld if at all possible where this will give effect to the reasonable expectations of the parties. The only exceptions shall be where this will produce consequences offending against the mandatory policies of the forum court in which case Article 18 empowers the court to deny the Applicable Law, even if it has been expressly selected by the settlor. But Article 15(2) nevertheless requires the forum court to consider adopting an approach that will preserve the overall validity of the trust insofar as that generality does not offend against the mandatory policy.
