Who should be the Appointors of my trust?
In general, due to the control issues, the appointor/s should in most cases include at least one of the people setting up the trust, e.g., one of the primary beneficiaries.
Some trusts include an "independent" appointor (usually the accountant), in addition to two joint appointors, to help make independent appointment decisions, but who will be "wiped off" the trust once both normal appointors die. This ensures that the accountant (or other independent appointor) and their spouse/children/etc don't end up with sole control of the trust.
If there are persons other than the primary beneficiaries listed as appointors, please let us know if they are to be joint appointors (i.e., with rights of survivorship), or if one or more of them is an independent appointor. For example, two appointors may be from different families (e.g., two brothers) and might not want to be joint appointors with rights of survivorship.
