Like a will, a trust requires you to transfer property to your loved ones after death. It is called a living trust because it is created while the owner or trustor is alive. It is revocable because it can be modified during the life of the trustee. The Trustor retains ownership of the property held by the Trust while the Trustor lives. So what is the cost of maintaining this type of trust? As I said, not much. As a general rule, an agent may calculate annually a commission representing a certain percentage of the trust`s capital and a certain percentage of the trust`s income. The legal fees are quite reasonable; But if your son is his own agent, he`s probably not going to pay a commission. A common misunderstanding about the cost of trust is that they are not significant, especially in the payment of trust after the death of the confrere.
