§187.  Income for benefit of grantor

Where any part of the income of a trust:

(1)  Is, or in the discretion of the grantor or of any person not having a substantial adverse interest in the disposition of such part of the income, may be held or accumulated for future distribution to the grantor; or

(2)  May in the discretion of the grantor or of any person not having a substantial adverse interest in the disposition of such part of the income, be distributed to the grantor; or

(3)  Is, or in the discretion of the grantor or of any person not having a substantial adverse interest in the disposition of such part of the income, may be applied to the payment of premiums upon policies of insurance on the life of the grantor (except policies of insurance irrevocably payable for the purposes and in the manner specified in R.S. 47:57, relating to the so-called "charitable contribution" deduction); then such part of the income of the trust shall be included in computing the net income of the grantor.  

As used in this Section, the term "in the discretion of the grantor" means "in the discretion of the grantor, either alone or in conjunction with any person not having a substantial adverse interest in the disposition of the part of the income in question."
