Legal Definitions - Duhig rule

The Duhig rule is a legal principle used in the oil and gas industry to interpret property titles. It was created to solve the problem of overconveyance of fractional interests in a property. The rule gives priority to the granted interest over the reserved interest.

For example, let's say that John owns a piece of land and wants to sell a 50% interest to Jane. However, John mistakenly sells a 100% interest to Jane. Later, John tries to sell the remaining 50% interest to Bob. According to the Duhig rule, Jane's interest would take priority over John's reserved interest, and Bob would not receive any interest in the property.

The Duhig rule is not accepted in all states and is generally limited to conveyances by warranty deed. It is important for property owners and buyers to understand this rule to avoid any confusion or disputes over property ownership.
