l. estoppel: m-BPtóSdisciose liens' The petition is not for the specific performance of a contract to convey an interest in land, The statute of frauds has therefore nothing to do with the case. In substance, the claim is, that defendant is in equity estopped from setting up or relying upon his tax deed, and that it should therefore be set aside, being, as it stands, a cloud upon plaintiff’s title. The express charge is, that, notwithstanding the negotiations and settlement, the defendant fraudulently retained the certificate (of purchase at the tax sale) and procured a deed, which, being of record, is a cloud upon plaintiff’s title and a fraud upon her rights.

*219That plaintiff’s purpose and intention was to remove all liens npon the land, we entertain no doubt; and that defendant should not, under the circumstances, be allowed to hold this deed; and that, upon every fair and equitable principle, the court wras right in ordering it set aside, we are equally clear.

If any thing is clear, or can be, it is that plaintiff agent, at the time of the settlement, asked for and del sired an exhibition of all liens, that they might be meft\ and discharged. By two disinterested and unimpeachable witnesses it is expressly established that defendant, more than once, stated that he had no other claims; that all the liens held by him were removed. It is true, he says in his testimony, that this particular tax lien was expressly excepted. In this, however, he is not corroborated. All the positive testimony, as well as the undisputed facts, are against him. Thus, the agent or attorney conducting the negotiation had money sent to him by his client, who resided at a distance, to clear the title of all incumbrance. The land was worth from $10 to $12 per acre, or, say $2,500; to redeem this,-with other land— all constituting the one farm — there was paid on the day named (Oct. 21, 1864) over $5,800; of which defendant received over $600, npon liens claimed in his own right. This tax lien then amounted to not more than $40 to $45; and certainly nothing could be more unreasonable than that the parties should designedly, and without any well developed motive or purpose, have left unsettled a claim and lien so small. They were all together ; they met for the purpose of settling these claims ; plaintiff’s attorney asked for all; the defendant said then (as the testimony, we think, establishes), that he had none other; this, too, he said afterward in the presence of another witness, when again appealed to by plaintiff’s attorney to know if all liens were settled; and it certainly *220would be a great wrong to now allow defendant to retain a title obtained either by mistake or fraud. And in this view it is not material whether the full amount necessary to redeem was paid or not. For if, by defendant’s mistake or fraud and especially without fault on the part of plaintiff or her agent, there was in fact a failure to pay sufficient to cover this with other liens, and yet, if plaintiff believed she was paying it, and would have paid it but for such fraud or mistake, defendant cannot, and will not in equity be allowed to, assert this title. And this proposition would be true whether applied to mortgage, judgment, tax or other liens or incumbrances. It is founded in reason, is self evident, and so well supported as to only need statement to meet approval. (See, however, Barber v. Lyon, 15 Iowa, 37, and cases there cited; also generally on the question involved, Pickard v. Sears, 6 A. & E. 469; Hawes v. Marchant, 1 Curtis, 136; Story’s Eq. Jur. § 146.)

It is of but little moment whether plaintiff or her agent did or did not in fact know that the taxes were unpaid for the year 1863. Under the circumstances, defendant was bound to disclose this lien. If he did not, he is concluded from afterward setting it up. He was in a situation which compelled him to speak, and if he remained silent he must suffer the consequences. It would violate the plainest principles of equity to say that, though called upon to exhibit all his liens, though he met the debtor and holder of the title to receive what was his due and assist in settling all incumbrances, he could protect himself because the plaintiff knew that these taxes were unpaid.

A. stands by and sees B. purchase an estate of C., upon which he knows he has a lien, and encourages the purchase, knowing that B. is ignorant of the lein, that he pays a full price, and yet afterward protects himself, or *221seeks to, upon the ground that his deed was recorded, and the purchaser was bound to take notice of it. To strike off just such fraudulent heads as this, is the especial office and work of estoppel. And the more of these found in the judicial basket the better for the integrity of the law and administration of justice.

Defendant stands by his title. The object of the petition is to set aside the deed. This was properly ordered. "Whether defendant actually received a sum sufficient to cover this lien with others, may admit of much doubt. Indeed, we confess that we incline to the opinion that he did not. But this was no fault of plaintiff; she had a right to have the deed set aside without conditions; and especially as there is no claim, by defendant in his pleadings or in any stage of the case, until in the argument here, that this sum should be repaid before depriving defendant of his title.

The judgment below will be affirmed, but without prejudice to defendant’s right to recover the sum so advanced, if in any action brought therefor he shall show himself entitled to it.

Affirmed.
