Estate planning

It depends on the purpose of the trust.  Any kind of asset protection requires and irrevocable trust.  But be careful, irrevocable means irrevocable, and if you change your mind, or the circumstances change, too bad.  An irrevocable trust is like a third person, it has its own social security number, pays taxes, and has a list of people who control it.  A trust is simply the list of instructions used to determine how and when the assets in the trust can be used.  The trust can hold all of the items you listed, the deed to a house, and two bank accounts.  The trust can also be the recipient of funds from a will, but does not include the will.
