§ 872.010.Definitions

Partition law leans on a handful of recurring words, so the drafters defined them once, up front, and let every later section rely on that meaning. An "action" under this title means a partition action specifically, not a lawsuit generally. "Property" covers both real and personal property, which matters because § 872.020 extends this title to both kinds of property. "Lien" is defined broadly -- a mortgage, deed of trust, or any other security interest, however it arose -- which sets up the lien-priority work courts do later under § 872.630.

"Remainder" is defined to sweep in several related future-interest concepts: reversion, reversionary interest, right of entry, and executory interest. That broad definition matters when a court sorts out successive estates under § 872.710, since partition of successive interests turns on exactly this kind of future-interest analysis. "Title report" is defined loosely enough to cover a preliminary report, a guarantee, a binder, or an actual policy of title insurance -- any of the documents a party might use to establish the state of title under § 872.220.

None of these definitions grant rights or impose duties by themselves. They exist to keep the rest of the title consistent, so a reader doesn't have to guess what "lien" or "remainder" means from one section to the next.
