Most states, particularly "pro-trust" states (such as Nevada), either allow or have codified statutory provisions that recognize the office and authority of a Trust Protector and a Trust Investment Advisor in a trust.  This app allows you to specifically identify either one or both to serve as such in your trust, in their respective capacities.

Trust Protector language may encompass a broad range of allowable decision making provisions although the basic power of allowing a Trust Protector to remove a trustee appointee and appoint a replacement is the primary/default Trust Protector provision in your MLCP trust format.  A Trust Protector appointee should generally be someone who is "independent" - meaning not having a vested interest in your trust estate.  Any provisions beyond enabling the Trust Protector to remove an appointed trustee should be carefully discussed with your legal counsel.

If you are currently using an investment advisor to provide you with personal financial management services, you should consider naming that individual as the Trust Investment Advisor (TIA) appointee in your trust.  As the TIA, such appointee will be able to advise the trustee of your trust concerning investments that your trustee would need to make as the fiduciary of your trust.  In fact, most independent corporate trustees will not accept a trustee nomination unless a TIA is appointed in the document.
