Basically there are two main reasons for setting up a trust as opposed to using a will to distribute your estate after your death. From what you say, neither of these probably applies in your case. First, a trust can be used to hold the assets of your estate for the benefit of a minor (or minors) or incapacitated persons. In that case the Trustee would be given instructions in the trust as to how the income or principal be distributed for their use. This is generally done when the grantor(s) have children or dependent(s) who cannot act in their own interest -- or for children whom the grantors think would not use the assets of their estate wisely, even though they are of age. The other reason is to shelter the assets of the trust from estate taxes. In 2000 the amount that could be protected in this way is $675,000 for a spouse in a B trust. For example a husband and wife acting as grantors in a standard A-B living trust would set up a revocable trust. When the first of them died, $675,000 could be put into the irrevocable B trust and not be subject to estate taxes on the death of the second grantor(spouse). The amount goes up each year, but using this device a couple could shelter $1,350,000 from estate taxes instead of just $675,000 which is what would happen if the assets were passed directly from the estate of the first one to die to the other spouse. There is another benefit, the trust avoids probate -- which is a public process. Many people would prefer that their estate not be public at the time of their death.
It sounds as though all you need to do is to specify as your personal representative in a will a person whom you trust to carry out your wishes as spelled out in your will or a later codicil to your will -- or even as you have asked them to do if you have someone you trust completely to do so. It is common for people to leave their personal representative freedom in distributing their personal property, and to depend on the will to specify the distribution of titled property such as real estate. Since a will must be probated, the probate court is in an oversight position to verify that the terms of the will are carried out by the personal representative.
Doesn't sound like you need a trust, but hope this is of some help.
