The defendant city is authorized to make street improvements under the general law and by the express terms of its charter. The provision in its charter that “Where permanent street improvements shall be made, the property bearing such assessment shall not be so assessed again until after the expiration of ten years from the date of the last preceding assessment,” is a limitation of power which may be waived by property owners. Charlotte v. Alexander, 173 N. C., 515; Shepard v. Barron, 194 U. S., 553; Elliott on Roads and Streets, *500Yol. 2, paragraph 733; Wright v. Davidson, 181 U. S., 371; High Point v. Clark, 211 N. C., 607; McQuillan, Vol. 5, page 836; Wake Forest v. Holding, 206 N. C., 425.
Speaking to the subject in Charlotte v. Alexander, supra, it is said : “There is no valid reason why citizens who wish to have their property improved by street paving may not expressly waive the charter restrictions and contract with the city to pay the actual cost. There is nothing against public policy in such agreement. On the contrary, it conduces to the general improvement of the municipality. When such contracts are entered into with full knowledge by the property owner the law will not permit him to repudiate it after the work is done and he has received the benefits. ... In our opinion, it is both good morals and sound law to hold that when a person has accepted the benefits of a contract, not contra tonos mores, he is estopped to question the validity of it.”
If the assessment constituted a valid lien upon the property as against Capps, then it is a valid lien against his successors in title. Seattle v. Hill, 62 Pac., 446; Cummings v. Karney, 141 Cal., 156. McQuillan, Vol. 5, page 828, in which the rule is stated as follows: “If the person who owned the property when the assessment was made is estopped from contesting the validity of the assessment, a subsequent purchaser taking with notice of the assessment will be deemed to have taken the property subject to the consequent burden, and cannot question the validity of the assessment.”
As the provision of the city charter, upon which plaintiff relies, constitutes a limitation upon power which may be waived, and as a subsequent purchaser acquires property subject to liens thereon which are valid as against his assignor, the plaintiff’s rights herein are dependent upon whether the purported assessment was a valid lien against the locus in quo as against Capps at the time he conveyed the property.
Capps filed a written petition with the city, which is of public record, in which he requested the improvement of Buchanan Street, and further requested that the total cost of said improvement ordinarily taxable against his property be specially assessed upon his particular lot of land. The improvements were made and he received the benefits thereof. After the assessment was affirmed and duly recorded he ratified the lien thereby created by paying two of the installments thereof. Thus he expressly contracted with the city that the cost of the improvement should constitute a lien upon his property, and ratified the lien after it was created of record. Certainly he could not be heard to contest the validity of the lien thus created. His conduct created more than a personal obligation. It created a specific lien upon his property.
It is to be noted that in Wake Forest v. Holding, supra, cited and relied upon by plaintiff, the judgment of the court below to the effect *501that the assessment created no lien upon the property of the defendant was reversed.
At the time Capps conveyed the locus in quo the assessment lien was of record and constituted notice to the purchaser of the existence of the lien. The Wachovia Bank & Trust Company, trustee, and the plaintiff, as purchaser from the trustee, acquired only such title to the property as was possessed by Capps at the time he executed the trust deed. At the time he executed the conveyance he was estopped to deny that by virtue of his contract relations with the city and his conduct with respect to the improvements and the assessments such assessment constituted a valid subsisting lien upon his property. As to him, and as to his successors in title, the lien is good.
The authorities cited and relied upon by the plaintiff are distinguishable and are not authoritative upon the facts in this case.
The judgment below is
Affirmed.
