delivered the opinion of the court.
The parties appear in this court in the same order as in the lower court and will he designated herein as plaintiff and defendants.
A general demurrer to plaintiff’s supplemental complaint as amended, filed by the defendants Nettie A. Rhodes and Earl M. Deeds, was sustained by the trial court. Plaintiff elected to stand, and the case was dismissed. Plaintiff assigns error.
The facts as set forth in the complaint, and admitted by the demurrer, so far as material, are as follows: On November 20, 1925, defendants, James B. Mitchell and Minnie Mitchell, executed five promissory notes to M. M. Holt aggregating $2,400 and secured the same by a trust *414 deed on land in Baca county, which was duly recorded. Thereafter these notes, for value, and before maturity, were sold and transferred to R. B. Holt, the plaintiff. On April 22, 1929, the Mitchells executed another note to defendant Nettie A. Rhodes and secured that note by a second trust deed on the same lands, which also was duly recorded on December 17,1929. Said second deed of trust contained the following’ provision: ‘ ‘ Said last above described land being’ subject to deed of trust for $2,400.00- of record in favor of M. M. Holt. ” On Januarv 7,1931, the Mitchells executed a new note to the plaintiff, R. B. Holt in the sum of $1,907.50', which was secured by a deed of trust on the Baca county land. The complaint alleg’es, ‘ ‘ That said deed of trust was given in lieu and in place of the said deed of trust” given to secure the original notes “and as a renewal and extension of such prior obligation, ’ ’ and “asa renewal of the balance thereafter due on the notes, ’ ’ secured by the original trust deed. This last deed of trust was recorded January 27, 1931. On April 12, 1932, subsequent to the recording* of all the deeds of trust, defendant Earl M. Deeds filed in the proper office a transcript of judgment to effect a lien on the land above described.
Simultaneously with the recording of the new deed of trust, plaintiff caused the original deed of trust to be released, without actual knowledge that there was an intervening* second deed of trust on record. Plaintiff further alleges, “That this mistake was due to the fact that plaintiff, in the transaction involving the release, relied upon the statement of Walter P. Powell, County Clerk and Recorder of Baca County, Colorado, to plaintiff, which statement was to the effect that the Deed of Trust recorded in Book 171 at page 288 (being the new deed of trust, to secure the note to plaintiff for the unpaid balance of the old notes), was the first lien of record since the Deed of trust recorded in Book 137 at page 105 (being the original or first deed of trust) as shown by the indexes in his *415 office. ’ ’ The foregoing facts are sufficiently set out in the complaint and on demurrer we must accept them as true.
Plaintiff asks that his deed of trust to secure payment of the $1,907.50, the balance due on the original notes, be adjudged a prior lien to the deed of trust given to defendant Ehodes, and, being in default, that it now be foreclosed. There is no claim that it appears by the complaint that any of the defendants were damaged or that they changed their positions in any respect by reason of the execution of the new note and trust deed.
The defendants vigorously insist that it appears from plaintiff’s complaint that he did not exercise the care required by law to ascertain whether there were other liens against the land before releasing the old deed of trust and recording the new one which was given to secure the unpaid balance, and for that reason plaintiff should not prevail in this action.
It is a well recognized proposition of law that one who relies on the negligence of another as a ground for recovery or to prevent recovery by another, before he can prevail must show that by reason of such negligence he has been damaged or has done something he would not have done or failed to do something he otherwise would have done to his prejudice in reliance thereon. In the absence of such showing equity will not permit one to escape the consequences of an act unless it appears that he exercised reasonable care for his own protection and to protect others who in turn might suffer damage in relying* on such act. "What is reasonable care depends on the circumstances of each particular case.
It is necessary in this case to consider when the question of such negligence becomes material, and on whom falls the burden of proving* negligence or the exercise of due care.
If the defendants, Ehodes and Deeds, did something they would not have done, or failed to do something* they otherwise would have done, in reliance on the release of the trust deed, and thereby suffered damage, then the *416 burden would rest on tbe plaintiff to show that he used due care under tbe circumstances, or was bimself free from negligence in executing tbe release, before be could show an equity in bimself superior to that in favor of tbe defendants. In tbe absence of a showing by defendants of a prejudicial change of position and damag*e to them, tbe matter of plaintiff’s negligence is not material. In such case tbe question is merely whether tbe act was induced by mistake. Plaintiff alleges it was so induced and asks relief on this ground.
Tbe fact involved, is tbe existence of tbe Rhodes trust deed at tbe time of tbe release of tbe first trust deed. Tbe mistake is tbe assumption of tbe nonexistence of tbe instrument when in fact it did exist. The mistake does not depend on tbe degree of care used to ascertain tbe existence of tbe second mortgage, but on tbe state of mind of tbe plaintiff with respect to its existence. If be bad a bona fide belief that it did not exist, so far as be was concerned such a belief was a mistake of fact. If be acted in reliance on such belief and changed bis status with reference to tbe land covered by tbe trust deed to bis own injury, then as between bimself and tbe owner of tbe land and third persons who were not injured be is entitled to have his status with reference to tbe land restored by equity. Those who are not injured, as was well stated by tbe court in
McKenzie v. McKenzie,
If other parties, in reliance on tbe act of tbe plaintiff in releasing tbe senior lien, bad changed their status with respect to tbe land or failed to act for a period of time within which, but for such release, they would have acted and were thereby damaged, then another situation would confront us and tbe question of whether the plaintiff exercised due care in making* such release or acted negligently in so doing would become material. When junior lien holders or others who acquire an interest in land show that their action or even inaction, induced by reliance on the release, has prejudiced them in any way, an addi *417 tional burden is cast on the plaintiff, namely, of showing that he exercised due care for his own protection and for the protection of those who might act, or fail to act, to their damage in reliance on the release.
The mistake and the bona tides of it are the matters material in the first instance in determining whether relief shall be granted as between the parties. Where third parties resist the correction of a mistake, the burden is theirs of showing damage resulting to them in reliance on the act done by mistake. When damage is established, the one who claims his act to have been done by mistake, then has the burden of proving that he exercised care commensurate with the surrounding circumstances to prevent injury to himself and to others who might rely on his act.
Counsel for defendants in their brief contend that under the decisions of this court, in the cases of
Capitol National Bank v. Holmes,
G-eneral statements of the rules of law applicable herein
*418
are to be found in 41 C. J. pp. 582, 587 and 588, and in 19 R. C. L. pp. 467, 472 and 473. Many cases are cited in 33 A. L. R., pages 149 et seq., which deal with situations similar to the one here involved. We quote from two of them. In the case of
Seeley v. Bacon
(N. J. Eq.),
In
Institute Building and Loan Ass’n v. Edwards
(1913), 81 N. J. Eq. 359,
The action of the trial court in sustaining defendants’ demurrer is reversed, and the cause is remanded with instructions to overrule the demurrer.
Me. Chief Justice Butlee and Me. Justice Bueke concur.
