Plain-English Summary

Partition is the process a court uses to divide property owned by more than one person -- either by splitting it physically among the owners ("partition in kind") or, when that isn't practical, by selling it and dividing the proceeds ("partition by sale"). Section 1501.1 opens the chapter by setting what a partition petition must contain: a description of the property and each owner's respective interest, so far as known.

Subsection B adds a special hurdle for partitioning a mineral estate, such as oil and gas interests. Beyond the basic description, the petition must specify, and the plaintiff must prove at trial by a preponderance of the evidence, that a co-owner is frustrating the plaintiff's development objective and that a Corporation Commission pooling order and unitization plan wouldn't achieve that objective. That extra burden doesn't apply, though, if the person seeking partition also owns part of the surface estate along with a mineral interest.

Frequently Asked Questions

What is partition of real property?

It's a court action to divide property among co-owners, either by splitting it physically among them or, when that isn't practical, by selling it and dividing the proceeds.

What does a partition petition have to include?

A description of the property and the respective interests of the owners, so far as known.

Why is partitioning a mineral estate harder than partitioning other property?

The plaintiff must additionally prove that a co-owner is frustrating the development objective and that a Corporation Commission pooling order and unitization plan wouldn't achieve it.

Does the extra mineral-estate proof requirement apply if I own the surface too?

No. It doesn't apply if the person seeking partition owns the surface estate, or part of it, along with a mineral interest.
