A corporate trustee has several advantages over an individual trustee:
A corporate trustee, being a separate legal entity, can exist indefinitely, whereas individual trustees will eventually die, may become incapacitated, or may want out for another reason.
Legal ownership of the trust assets
Assets in a trust are held in the name of the Trustee on behalf of the trust. If individuals act as the trustee of your trust and you later want to change the trustee, you will have to change the legal owner of your trust’s assets. Conversely, you can simply change the shareholders and directors of a corporate trustee which will not change the legal owner of the trust’s assets.
Asset protection & limited liability
Individual trustees can be personally liable for any loans taken out or liabilities that the trust may incur. If a corporate trustee is used, liability will generally be limited to the assets of the trustee company itself.
