Transfer of assets.

Notwithstanding Section 3 of this title and Section 299.15 of

Title 60 of the Oklahoma Statutes, the corpus and income of a

preservation trust shall be exempt from attachment or execution and

every other species of forced sale and no judgment, decree, or

execution can be a lien on the trust for the payment of debts of a

grantor, except a child support judgment. Any incremental growth

derived from income or an increase in value of the corpus of a

preservation trust shall also be considered protected by this

section. Transfer of an asset to a preservation trust does not

affect any mortgage, security interest or lien to which that asset

is subject.
