There are many situations in which a trust is very effective. For example, property in a trust need not go through the cost and process of probate when you pass.
Probate is the process which permits property (such as land) owned by a deceased person to be passed on to a beneficiary. But probate in Idaho can’t address a condo or cabin located in another state. Those who own a home here, and a second home in Arizona, may want to put both properties into a trust and avoid paying two attorneys in two different states for probate.
