Brosnan v. Brosnan

Background

Timothy Brosnan died in the District of Columbia in 1919 leaving a will dated July 29, 1918. His widow filed a caveat challenging whether he had the mental capacity to make the will. The Court of Appeals asked the Supreme Court whether, under District law, the person who challenges a will must prove lack of capacity or whether the proponents must prove capacity. The local code allows interested persons to file caveats and requires that a will maker be of sound and disposing mind to make a valid will.

Reasoning

The central question was who bears the burden of proof on mental capacity in a caveat case. The Supreme Court relied on its prior decision in Leach v. Burr, which had held that the challenger bears that burden in the District of Columbia. The Court explained that an ancient presumption favors the testator’s sanity and that placing the burden on the challenger avoids confusing fine distinctions in jury trials. The Court therefore declined to alter the settled rule and instructed that the burden rests on the caveator.

Real world impact

As the Court explained, anyone who asks a court to overturn a will in Washington, D.C., must prove the testator lacked mental capacity. That rule applies whether the challenge comes before probate or in a later effort to revoke probate. The decision gives clear guidance to courts, juries, and families about who must carry the proof in will-disputes.

Dissents or concurrances

The Court noted that some earlier decisions and other jurisdictions had reached different results, but it reaffirmed Leach v. Burr and rejected a contrary suggestion in an earlier local decision.
