If a person dies without a will (intestate)—and with no heirs (relatives or descendants)—ownership of the deceased person’s (decedent’s) property may be transferred to (or said to revert to) the state government (usually the state treasury) through the common law doctrine of escheat. In addition to enriching the state treasury (or the Lord in feudal England), escheat prevents property from remaining in limbo with no rightful owner.

A state’s common law is comprised of court opinions written by judges to resolve disputes and most states adopted the legal doctrine of escheat from the English common law (from England) soon after the founding of the United States and each state’s admission to the union. But in more recent years many state legislatures have defined the law of escheat in their state’s statutes—making it statutory law—which is also known as codifying the law, because it is then part of a code or statute.

The property subject to escheat laws is sometimes referred to or classified as unclaimed or abandoned property. Upon transfer to the government the unclaimed or abandoned property may be referred to as escheated property. And in some states there may be a period (a statute of limitations) in which heirs or rightful owners of the property may be able to reclaim escheated property.

Escheat laws vary from state to state and often depend on the nature of the asset involved (personal property, real property, bank account, brokerage account).

In Michigan, if a person dies intestate (without a will) and has no identifiable heirs, the property of the deceased may escheat, or revert, to the state. This process is governed by Michigan's Estates and Protected Individuals Code (EPIC). Under Michigan law, if after a diligent search no heirs are found, the property will eventually become the state's through escheat. The state holds the property for a period during which potential heirs can come forward to claim it. If no heirs claim the property within the designated time frame, the property permanently becomes state property. The time frame for claims in Michigan is generally set at a period of 5 years for real property and 3 years for personal property after it has escheated to the state. The Michigan Department of Treasury is responsible for handling escheated property. It's important to note that the specifics of escheat laws can be complex and may vary depending on the type of property involved. Therefore, consulting with an attorney for specific cases is advisable.
