Ejectment. In his complaint plaintiff alleges that he is the owner “of an undivided one-half interest” of, in, and to the tract of land therein described.

After certain denials, the answer proceeds:

“ Further answering, said complaint, and as a special defense to said action, defendant avers that for more than five years prior to the commencement of said action the defendant, and those through and under whom he claims, holds, and owns, have been in the continuous, actual, open, and notorious and exclusive possession of said premises, holding adversely to the plaintiff’s pretended right or claim, and holding the actual, open, notorious, and exclusive possession of said tract of land and premises, and of every part and portion thereof, adversely to said plaintiff and all comers. Defendant avers, that neither the plaintiff nor his ancestors, predecessors, or grantors, nor any or either of them, was or were, or have been, seized or possessed of the premises sued for, or of any part or portion thereof, within five years next before the commencement of this action.”

No objection has been made to the foregoing as a plea of the Statute of Limitations. Did the Court below find upon the issue thus presented ?

The Court found, in effect, that, prior to the 24th day of September, 1860, and from November 15th, 1859, the plaintiff and one Sanor, grantor of defendant, claimed a right to the possession, and exercised acts of ownership upon a tract of land, including the demanded premises, as tenants in common; that Sanor then, for a valuable consideration by him paid, took and received a deed from one Cocke, whereby the latter remised, released, and quit-claimed to said Sanor all his estate, right, title, *182and interest in the lands whereof Sanor and plaintiff had theretofore claimed to be the owners as tenants in common; that Sanor thereupon went into the open, notorious, and exclusive possession of said land, claiming to be the owner of the entirety thereof, under said deed—“said Ward (who had previously conveyed to plaintiff and Sanor), Sanor, and plaintiff having prior to that time had possession of said land to the extent of grazing their stock thereon; and said Sanor, within four months after such purchase, so claiming to be the owner thereof, built a dwelling-house and barn thereon, and inclosed the whole thereof with a good and substantial fence, * * * and said Sanor, from the time he built said dwelling-house, and until the time of his conveyance to defendant, * * '* lived in said dwelling-house with his family, and was in the open, notorious, and exclusive possession,” * * * keeping the same inclosed as aforesaid, and receiving to his exclusive use the rents, issues, and profits of the whole, “ claiming to be the sole owner of the entirety thereof.”

The Court further found, that, on the 3rd of December, 1864, Sanor and wife, by deed, remised, released, and quit-claimed to defendant, for the consideration of $500, all their interest in the land described in the complaint; that on the day of the execution of said deed, Sanor delivered possession of the entire premises to defendant, who has since been in the sole, open, notorious, and exclusive possession of the same, keeping the same inclosed with a good and substantial fence, and receiving to his exclusive use and benefit the entire rents, issues, and profits—“ claiming to be the owner under said deed of the whole thereof.”

Neither of these is a finding that plaintiff was ousted more than five years before the commencement of the action, and that defendant, or defendant and his grantor, had been in adverse possession since the ouster; or a finding that defendant or his grantor was in adverse possession continuously more than five years prior to the commencement of the action; or a finding that defendant for more than five years prevented plaintiff from entering into the enjoyment of the premises in common with himself.

It is not necessary here to decide whether a “-finding ” is suf*183ficient if it be as broad as the pleading. In the case before us, the Court below failed to find the material and ultimate fact alleged. While the facts found tended to prove adverse possession for the statutory time, yet the facts found did not necessarily constitute adverse possession. The plaintiff was in possession by and through defendant, his co-tenant, when (as found) defendant determined to assert a claim to be the sole owner. When was plaintiff ousted ? From the moment defendant began to claim the land as exclusively his own? Not so; but from the point of time when plaintiff became aware of such claim, or (at the very least) from the time when, as a prudent man reasonably attentive to his own interests, he ought to have known that his co-tenant asserted an exclusive right to the land of which both had had the common possession. The purchase of an outstanding claim of title by Sanor, and his quit-claim to defendant (if plaintiff had notice of the purchase and conveyances, which does not appear), the greater or less notoriety of defendant’s exclusive claim, his erection of buildings and other improvements, the pernancy of the entire profits^ the payment of the taxes, and the like, are evidentiary circumstances, of more or less weight, tending to prove ouster and adverse possession—no more. All of them may have occurred or existed, and yet plaintiff may not have known (or, as a prudent man, as aforesaid, may not have been bound to know) that defendant claimed the whole title, and so may not have been ousted five years before the commencement of the action, nor the defendant have had adverse possession for that length of time.

The difference between the finding in a special verdict—of an ouster—and of probative facts, which go toward establishing an ouster, was pointed out in Carpentier v. Mendenhall, 28 Cal. 484. It is illustrated in Carpentier v. Webster, 27 Cal. 524, where the occupant refused to let in his co-tenant. In Carpentier v. Gardner, 29 Cal. 160, where it was held that the denial of any title in the co-tenant was evidence of ouster. It has been said that the taking of actual possession of land under a deed which purports to convey the whole thereof, under a belief that it conveys the whole, while in fact it gives title to an undivided portion only, is not an ouster of a tenant in common who owns the other undivided part. (Seaton v. Son, 32 Cal. 481.)

*184The findings in the record are not of such probative facts as enable the Court to declare that the ultimate fact of adverse possession necessarily results from them. (Conveny v. Hale, 49 Cal. 552.)

Judgment and order reversed, and cause remanded for anew trial.
