La. Stat. tit. 9 § 1955
If a married couple transfers property to a trustee of a trust they alone have created, or if the trustee of that trust is designated as the beneficiary of a benefit payable upon a spouse's death under a policy or plan, and the transferred property or the spouses' interest in the policy or plan is wholly or partially their community property, the trust instrument may direct the trustee to divide the trust after the termination of the community into two separate shares or trusts according to the spouses' respective ownership interests in the property, or in the policy or plan. The two separate shares or trusts may be governed by different terms and conditions in the trust instrument, even as to the designation of beneficiaries. A "policy or plan" shall include a life insurance or annuity contract, and an employee benefit plan, individual retirement account, or similar benefit.
