The trustee or trustees of a trust established by the testator or others as provided in Code Section 53-12-71 shall not be required to inquire into or audit the actions of the executor or executors of the testator's estate or to make any claim against the executor or executors unless specifically directed to do so by the trustor or trustors in the trust instrument. In the event that the trustee or trustees are authorized or directed by the trustor or trustors in the trust instrument to pay or advance any part or all of the trust property to the executor or executors of the testator's estate for the payment of debts, taxes, and expenses of administration of the testator's estate, the trustee or trustees shall not be liable for the application of the trust property so paid or advanced and shall not be liable for any act done or omitted to be done by the executor or executors with regard to the trust property.
