With personal financial arrangements, the trust is not the protection for your family. The protection is the trustee acting skillfully to fulfill the trust's provisions. A trust can be the means to protect your family against the unexpected. At any time, you could become disabled or otherwise unable to manage your assets. Good planning can't assume that your family would get through with the aid of relatives and friends.
