Such assessments shall be entered in the proper municipal lien and judgment docket in the prothonotary's office, and shall, if filed within six months from the completion of the improvements, without the issuing of a scire facias to revive, remain a first lien upon the property assessed until fully paid, having precedence of all other liens, except taxes, and shall not be divested by any judicial sale, unless the payment of the same is provided for from the proceeds of such sale.
The assessment shall state the name of the city claimant, the name of the owner or reputed owner, a reasonable description of the property, the amount claimed to be due, for what improvement the claim is made, and the time when the assessment was finally confirmed or made.
