The published notice shall state that creditors of a deceased settlor must present their claim within four months after the date of the first publication of the notice or any claim or collection efforts which otherwise could have been asserted or enforced against the trust or assets thereof may be barred.
For purposes of this section, a trustee has knowledge of a creditor or potential creditor if the trustee is aware that the creditor has demanded payment from the settlor or the settlor's estate.
However, the trustee may pay creditor claims without liability so long as the trustee determines that, at the time of the determination, the assets of the trust are reasonably adequate to allow for payment of the claim in view of the type of proceeding, the amount at issue, and the likelihood of its probable success.
