Wills and Trusts:
A successor trustee is the person who will manage your assets for you when you die or if you should become incapacitated. This person or persons will have the right to manage your affairs without the need for any probate court. The successor trustee will immediately have the same powers that you as grantor/trustee had to buy, sell, borrow, or transfer the assets inside the trust. More importantly, the successor trustee has the right to distribute the trust's assets according to your instructions in the trust. This immediate control can allow your estate to be transferred to your children or loved ones right away avoiding the time delay of probate, which can usually consume anywhere from 6 months to 2 years.
The successor trustee does not have the legal right to change your trust. The trust becomes irrevocable or unchangeable after the death of the grantor(s). However, the successor trustee does have the right to manage the assets in the estate, but must do so for the benefit of the beneficiaries.
