Legal Question in Criminal Law in California

Re: court rules

Your question is a bit vague. "Standing" is the right to bring or defend a lawsuit. Only people or various entities (governments, partnerships, businesses, trusts, etc.) can have standing. No document can ever have standing under any circumstances.

You're probably asking whether notarized statements may be used as evience, and the answer is "it depends". Such a document ordinarily cannot replace live testimony by the person who signed it (so if you think you can avoid testifying by submitting such a document you're wrong), but there are a variety of ways in which they might be admissible as evidence. Whether a particular document is admissible in a particular case will depend upon the facts of the case, the content of the document, what it is being offered to prove and a variety of other case-specific facotrs.
