Common questions
Frequently Asked
5
What quantum of proof is required to convict a defendant of a crime?+
No person may be convicted unless each element of the offense is proved beyond a reasonable doubt. In the absence of such proof the innocence of the defendant is assumed.
When may a court direct an offer of proof during trial?+
The court may direct that an offer of proof be made in question-and-answer form. The court may also make a statement about the character or form of the evidence and the ruling.
Who bears the burden of proof on causation in a tort case involving multiple actors?+
The plaintiff bears the burden of proving that the tortious conduct of the defendant caused the harm. When multiple actors combine to cause harm and one seeks to limit liability by apportionment, the burden of proof on apportionment rests on each actor seeking the limitation.
What must a proponent of a will establish in a contested probate proceeding?+
The proponent must establish prima facie proof of due execution in all cases and, if also a petitioner, prima facie proof of death and venue. Contestants bear the burden of establishing lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation.
Under what circumstances is an offer of proof unnecessary to preserve error?+
Once the court rules definitively on the record before or at trial, a party need not renew an objection or offer of proof to preserve a claim of error for appeal.
