Welcome! Thank you for your question.
Yes, the SNT beneficiary can be executor of the parents' Will. The beneficiary can also be trustee of a trust created in the parents plan.
However, the disabled beneficiary should not be trustee of any trust that is created for the benefit of the disabled beneficiary. This is because a SNT is a purely discretionary trust at it heart. The trustee has ultimate and full discretion on the use of the trust assets. If the beneficiary is also the trustee that ultimate discretion gives the beneficiary too much control and therefore social security will not exclude them.
