There are always specific reasons for making an irrevocable trust agreement. Perhaps it involves a family business where some of the family members are getting on in years and the family wants to make certain that management continues to run smoothly even if hindrances, such as senility, enter the picture.
Many times the reasons for an irrevocable trust involve estate and/or income tax avoidance. In order to be successful in such avoidance, the trustor must not have any direct or indirect power or control over the trust property or income. The regulations on this subject, set out in the Internal Revenue Code, must be carefully followed.
