A more thorough explanation:

In trusts and estates law, the slayer rule is a legal principle that prevents a murderer from inheriting any property or assets from their victim's estate. This means that if someone intentionally and unlawfully kills another person, they cannot receive any benefits from that person's will or trust.

The slayer rule is based on the idea that it would be unjust for a killer to profit from their crime. Therefore, the law presumes that the murderer has forfeited their right to any inheritance or property interest in the victim's estate.

The slayer rule applies only if the killing was intentional and felonious. This means that if someone accidentally causes the death of another person, they may still be able to inherit from that person's estate. However, if the killing was intentional and unlawful, the slayer rule will apply.

For example, if John kills his wealthy uncle in order to inherit his estate, the slayer rule would prevent John from receiving any of his uncle's assets. Even if John is not convicted of the murder, the slayer rule would still apply because the evidence suggests that he intentionally and unlawfully caused his uncle's death.

Another example would be if Sarah kills her husband in order to collect his life insurance policy. Even if Sarah is not convicted of the murder, the slayer rule would prevent her from receiving any benefits from the policy because she intentionally and unlawfully caused her husband's death.

In summary, the slayer rule is a legal principle that prevents murderers from inheriting any property or assets from their victims. This rule applies only if the killing was intentional and felonious, and it ensures that killers cannot profit from their crimes.
