Plain-English Summary
Section 1502 covers gaps in what a partition plaintiff knows. If the number of shares or interests in the property is known but the owners aren't, or if some interest is unknown, contingent, or doubtful, the petition must lay out those facts with reasonable certainty rather than skip over them.
Frequently Asked Questions
What if you don't know who owns a share of the property?
The petition still must set out that fact with reasonable certainty, along with what is known about the number of shares or interests.
Does this apply to interests that are contingent or uncertain?
Yes. It covers interests that are unknown, contingent, or doubtful, requiring the petition to state those facts with reasonable certainty.
How certain do these facts need to be in the petition?
