On the trial of any proceeding for any forcible entry or forcible detainer, the plaintiff shall only be required to show, in addition to the forcible entry or forcible detainer complained of, that he was peaceably in the actual possession at the time of the forcible entry, or was entitled to the possession at the time of the forcible detainer. The defendant may show in his defense that he or his ancestors, or those whose interest in such premises he claims, have been in the quiet possession thereof for the space of one whole year together next before the commencement of the proceedings, and that his interest therein is not then ended or determined; and such showing is a bar to the proceedings.

In one sentenceSection 1172 requires a plaintiff in a forcible entry or forcible detainer case to show only peaceable actual possession at the time of the forcible entry, or entitlement to possession at the time of the forcible detainer, while letting the defendant defeat the claim entirely by proving quiet possession for the full year before the case began.
Full Text of § 1172
Plain-English Summary
Forcible entry and forcible detainer are narrower claims than an ordinary unlawful detainer for unpaid rent — they're about possession taken or held by force. Section 1172 keeps the plaintiff's burden light: at trial, the plaintiff need only show peaceable actual possession at the moment of the forcible entry, or a right to possession at the moment of the forcible detainer, along with the forcible conduct itself.
The defendant gets one specific way to knock the whole case out. Showing that the defendant, an ancestor, or someone the defendant's interest traces back to has held quiet possession of the property for a full year running right up to when the proceeding started — and that the defendant's interest in the property hasn't ended — is a complete bar to the action, regardless of how the entry or detainer happened.
Frequently Asked Questions
What must a plaintiff prove in a forcible entry case?
Peaceable actual possession at the time of the forcible entry, plus the forcible entry itself.
What must a plaintiff prove in a forcible detainer case?
That the plaintiff was entitled to possession at the time of the forcible detainer, plus the forcible detainer itself.
Is there a defense based on how long the defendant has held the property?
Yes. Showing quiet possession for the full year before the proceeding began, with an interest in the property that hasn't ended, bars the action completely.
