Between the 1970s and 1990s, state custody laws moved from maternal preference to the “best interests of the child” doctrine, which gives fathers and mothers equal treatment in child custody assignment. We exploit exogenous variation across states in the timing of this custody law change to estimate the long‐term implications of exposure to a gender‐neutral custody law regime. We find that childhood exposure to gender neutral custody laws has a negative effect on educational attainment. A child exposed to gender neutral custody law is less likely to graduate from high school by 1.5 to 2.0 percentage points.
