Fiancée Poisons Testator
Carla slipped poison into Victor's drink at a celebratory dinner after he changed his will to leave her rental properties. A probate court later found by a preponderance of the evidence that Carla acted with criminal intent to obtain the properties. Because the killing was done per feloniam, Carla forfeited her devise and the properties passed to Victor's son as if she had predeceased him.
Spouse Convicted of Murder
Carla was convicted in criminal court of intentionally killing her husband Ethan by causing his car to explode. The probate court treated the conviction as conclusive proof of criminal intent.

Common questions
Frequently Asked
4
Does a criminal conviction automatically bar a slayer from inheriting?+
A final criminal conviction for the felonious and intentional killing of the decedent conclusively establishes slayer status in a later civil proceeding. The probate court need not relitigate the facts. Even without a conviction, however, the court may still find slayer status by a preponderance of the evidence in the probate action.
What standard of proof applies in probate court to determine slayer status?+
The probate court applies the civil preponderance standard to decide whether the beneficiary feloniously and intentionally killed the decedent. A criminal conviction is not required. The court may weigh forensic reports, witness testimony, and other evidence independently of any criminal proceeding.
Does an acquittal on homicide charges prevent a civil finding of slayer status?+
An acquittal does not preclude a civil determination. The criminal standard of proof beyond a reasonable doubt is higher than the civil preponderance standard. The probate court may still find that the beneficiary acted with criminal intent and bar inheritance even after an acquittal.
Does the slayer rule apply to nonprobate transfers such as life insurance?+
Yes. The rule bars a slayer from receiving any benefit that depends on the decedent's death, including life insurance proceeds and retirement plan death benefits. The same criminal-intent finding that disqualifies a beneficiary under a will also disqualifies the beneficiary from nonprobate transfers.
