The statute declares, that every mechanic, or other person, who shall furnish any materials for any build*594ing, erection, or improvement upon land, or for repairing the same, under or by virtue of any contract with the owner or proprietor thereof, shall have for the materials furnished a lien, to the extent, and in the manner provided, upon such building, erection, or improvement, and upon the land belonging to such owner or proprietor on which the same are situated, to the extent of one acre, or, if situated in any city, town, or village, on the lot of land. As respects the land, the lien exists to the extent of all the right, title and interest, owned therein by the owner or proprietor of such building, erection, or improvement; thus limiting the lien to the estate of the party contracting for the materials. The lien is inchoate and defeasible — dependent for its completion upon compliance with the statutory requirements. It is defeated and lost, if the mechanic, within six months, or other person within four months, after the 'indebtedness has accrued, fails to file with the judge of probate, of the county in which the property is situated, a just and true account of the demand due him, after all just credits have been given, and a true description of the property, or so near as to identify the same, upon which the lien is intended to apply, or for which the materials were furnished, with the name of the owner or contractor, if known ; which statement shall be verified by the oath of the claimant, or some other person having knowledge of the facts. — Code, 1876, §§ 3440, 3444; Welch v. Porter, 63 Ala. 225.
The claim of the plaintiff is for materials furnished, under a contract with the defendant, Robbins, for a dwelling-house and other improvements on land belonging to him. The claim was verified, and filed with the judge of probate, in the manner and within the time required by the statute; giving a description of the entire tract of land, on which the improvements are situated, but not describing or attempting to describe any “ one acre ” of the entire tract, which consisted of about thirty-eight acres. The claim as filed shows that there is a mortgage on the laud, which was executed by Robbins to the Battle-House Company prior to the erection of the building and other improvements, and which is unsatisfied. It is insisted, that the lien on the dwelling-house and other improvements is defeated and lost, by the failure of the claimant to give, in the claim filed, a description of the acre of land, to which the statute extends the lien upon compliance with its provisions.
The contention is founded on the common-law doctrine, that all buildings, annexed to land, become part of the freehold. As a general rule, a building erected upon land becomes a part of the realty, and the property of the owner of the land ; but, *595by express agreement, another may have a ' separate , property in such building, with the right of reínoval; and a mortgage may be given on improvements, without conveying any title to the land, which operates to pass a right to the improvements. On like principle, a lien may be created by statute on the improvements, without its extension to the realty. There is, in this respect, no inseparable connection between the buildings and the land.
It may be conceded that the earlier acts, creating mechanic’s liens, secured the lien exclusively to real estate. Later legislation has been governed by a more liberal policy, and has proceeded on principles more effectual to prevent the owner of land from appropriating the labor and capital of others to the enhancement of its value without compensation. Its tendency and effect are to abrogate, in favor of the lien, the common-law rule; and to extend it to the improvements and the land, both or either. It is conceded, it was not the intention of the statutes to give a lien on the materials as such, hut on the buildings in the construction of which they are used, which must be erected on land, under or by virtue of a contract with the owner or proprietor thereof. The lien attaches only to such building, erection, or improvement, as constitutes, under the common-law doctrine, a part of the realty. Notwithstanding, when a prior lien, incumbrance or mortgage exists on the land, a lien, not necessarily connected with, nor dependent upon a lien on the realty, for materials furnished, is secured to the buildings, erections, or improvements. By section 3442, the lien attaches, and is preferred to all other incumbrances, which may be attached to or upon such buildings. erections, or other improvements, on the ground, or ■either of them, subsequent t,o the commencement of such improvements ; and attaches to the improvements for which they are furnished, in preference to any prior lien, incumbrance or mortgage on the land, upon which such improvements are erected; “ and any person enforcing such lien, where there is a prior mortgage or lien upon the iand, may have such building, erection or improvement sold under execution, as provided in this chapter, and the purchaser may remove the same within a reasonable time thereafter.” An available lien on the improvements is secured to the person furnishing the materials, although it may be unavailing as to the realty. The operation of this section is to dissever, in the case of a prior mortgage on the land, the improvements and the realty, by giving a superior lien on the buildings, and conferring on the purchaser the right to remove.
The material-man may waive the lien as to the entire property, by not filing a claim, or bringing suit, as required by the *596statute; and we see no reason why it may not be waived as to a part, and claimed as to the residue of the property. The loss of the lien on both the land and improvements is not the sequence of a claim of lien on improvements only. The statutory lien, so far as relates to the realty and improvements, is necessarily not an entirety. In Montgomery Iron Works v. Dorman, at the last term (ante, 218), we held that, to complete the lien on the realty, the claim filed must contain a true description, or so near as to identify the same, of the lot of land, or of the “ one acre,” as the same may or may not be situated in any city, town, or village. If the claim contains such description, and conforms in other respects to the requirements of the statute, it can not be controverted, that a lien on the land is secured. Rut section 3444, after requiring the filing of a verified account of the demand, and a description of the property upon which the lien is intended to apply, provides, “which statement of account and description, when so filed, shall be a lien upon the building or other improvements, with all the rights and privileges under this chapter, from and after such filing.” The real estate is omitted in this declaration of the property, upon which there shall be a lien. To hold that this omission operated to exclude the lien upon the land, secured by section 3440, would do violence to the spirit and policy of the statute, and would disregard the intention of- the legislature. Some meaning, therefore, must be assigned to the words of the statute — ■“ which statement of account and description, when so filed, shall be a lien upon the building or other improvements” — which is not in conflict with the construction that a lien may also be charged on the land. The operation of these words, and their only operation, is to declare and authorize a lien upon the building or -other improvements, independent of a completed lien on the land. .If this is not their meaning and operation, it was unnecessary to have incorporated them in the statute; for, without them, filing the account and description of the property, as required by section 3444, would have operated to complete the inchoate lien upon both the buildings and the land, created by section 3440.
Construing the sections of this chapter of the Code in pari materia, we hold that, when there is a prior mortgage on the land, the person furnishing materials for a building, erection or improvement thereon, may complete a lien on the building, erection or other improvements, without completing it on the land. In such ease, the buildings and the improvements being the only property upon which the lien is intended to apply, he need only describe the building and other improvements and the tract of land on which they are situated. It is not *597necessary to describe tlie “ one acre,” when it is not intended to apply the lien thereon. The description of the' dwelling-house, as stated in the claim filed, and in the complaint, is sufficient to identify the same; but there is no sufficient description of the improvements, other than the dwelling-house. The description should be sufficient to identify them as the improvements for which the materials were furnished, and to show that they were improvements of the kind contemplated by the statute. The failure, however, to sufficiently’ describe the other improvements, does not invalidate the lien on the dwelling-house. The lien on the property sufficiently described is valid, the other requisitions of the statute being complied with.
On the agreed statement of facts, the plaintiff is entitled to have a lien charged on the dwelling-house, for the materials furnished therefor.
