§ 855.Filing Petition Upon Delinquent's Failure Or Refusal to Contribute

This section is the escalation point. If 90 days pass after service of the § 853 notice and the delinquent coowner still hasn't paid a proportionate share of the taxes, the coowner who carried the burden can take the dispute to court.

The vehicle is a verified petition, filed in the superior court of the county where the mine or mining claim sits. The petition has to set out the facts supporting the claim and describe the mine or mining claim with particularity -- vague descriptions won't do, since the whole point of the later proceedings is to potentially transfer a specific ownership interest in a specific property.

Filing the petition doesn't decide anything by itself. Section 857 requires the clerk to set it for hearing and give notice, and § 858 is where the court weighs the evidence and can order judgment.
