(h) If the notification by the trustee is served because a revocable trust or any portion of it has become irrevocable because of the death of one or more settlors of the trust, or because, by the express terms of the trust, the trust becomes irrevocable within one year of the death of a settlor because of a contingency related to the death of one or more of the settlors of the trust, the notification by the trustee shall also include a warning, set out in a separate paragraph in not less than 10-point boldface type, or a reasonable equivalent thereof, that states as follows:
"You may not bring an action to contest the trust more than 120 days from the date this notification by the trustee is served upon you or 60 days from the date on which a copy of the terms of the trust is mailed or personally delivered to you during that 120-day period, whichever is later."
