Things which are done in the king’s court are presumed to be rightly done.

Explanation

Official acts of a court of record carry a presumption of regularity — the party challenging them bears the burden of showing error.

Where this applies

• A losing party claims the trial court made procedural errors, but the appellate court presumes the trial was conducted properly and requires proof of the alleged mistakes.
• A defendant argues that the jury was improperly instructed, but the court of appeals presumes the trial court's instructions were correct unless the record shows otherwise.
• A party challenging a judgment must point to specific errors in the record, because everything done in the court of record is presumed to have been done correctly.
