Article 6Cancellation of Instruments
Section § 3412
This law allows someone who is worried that a written document could cause them harm because it might be invalid or can be invalidated to ask a court to officially recognize this and have the document canceled or handed over.
Section § 3413
This law says that if a document clearly looks invalid on its own or when viewed with another necessary document, it cannot be considered harmful under the previous law section.
Section § 3414
This law states that if a document includes multiple rights or obligations, only the part that is problematic can be canceled, leaving the rest intact.
Section § 3415
In California, if you've lost or destroyed a private document that matters to you, you can take legal action to either prove the document existed or get a duplicate made. If it's a negotiable instrument, which means something like a check or promissory note, the court will require you to provide a financial guarantee. This guarantee protects the person giving you the duplicate from any losses if the original document shows up later.
