delivered the opinion of the court.

To an action of indebitatus assumpsit, by a material man, for materials furnished in the ejection of a building, brought against the owner and builder under the lien law of 1853, the defendant pleads in bar—

1st. That he conveyed the land and premises on which the lien is claimed to a third party, and that the deed was recorded in the clerk’s office of the county of Middlesex, in which the premises were situate, before the lien was filed.

2d. That the lien filed was notin due form of law, specifying the particulars in which the lien is alleged to be defective.

To both pleas the plaintiff demurs. The question certified for the opinion of this court is whether the pleas are sufficient.

Both pleas are clearly defective. Where the claim is filed within the time prescribed by the act, the statute makes the debt a lien on the building and on the land whereon it stands. The lien attaches at the commencement of the building, or one year before the filing of the claim in the clerk’s office. Nixon’s Dig. 489, § 11. If the plea was designed to set up the defence, that the action was not commenced against the owner and builder as required by the statutes, that fact should have been expressly averred, and not left to inference.

But both pleas are illegal, upon another ground. The statute (section 9) prescribes the form of the declaration, and directs that the practice, proceedings, and pleadings thereon shall be conducted, and the judgment entered as in suits to recover money due on contract. The defendant may have any defence or plea to the action that might be *75had bv the builder to any action on the contract without the act. And, in addition, the owner may plead that the house or land is not liable to the debt; and in such case it is necessary for the plaintiff, to entitle him to judgment against the house and land, to prove that the provisions of the act requisite to constitute such lien have been complied with. Judgment may be rendered against the builder for the debt, and the real estate be discharged of the lien.

From this statement of the material provisions of the act, touching the proceedings in a suit against the builder and owner for the amount of the claim, and to enforce the lien, it is.clear that no matter which merely affects the existence of the lien can be pleaded in bar of the action. The pleadings must be such only as would avail in an action brought to recover money due on contract. Neither a change of title nor a failure to file the claim in compliance with the law, however they might impair the validity of the lien, could in any wav affect the plaintiff’s right to recover the debt from the builder. They cannot, therefore, be pleaded in bar of the action.

If the owner of the land intends to question the validity of the lien, the plea prescribed by statute is, that the house or land are not liable to the debt, and it thereupon becomes necessary for the plaintiff', to entitle him to judgment against the real estate, to prove that the provisions of the act requisite to constitute such lien have been complied with. As now pleaded, the matter of defence which affects the lien only, if' established by proof, will bar the action against the builder, whereas, if properly pleaded under the provisions of the statute, it would avoid the lien only, and the plaintiff, notwithstanding, would be entitled to judgment for his debt against the builder. The plea can avail the owner only, not the builder.

The demurrer to both pleas is well taken, and the Circuit Court should be advised accordingly.
