LOHR, Justice.
In accordance with C.A.R. 21.1, the United States Court of Appeals for the Tenth Circuit has certified to the Supreme Court of Colorado two questions of law pertaining to a pending federal case:
(1) Does a lien created by the City of Glenwood Springs Municipal Code § 22-2 for unpaid utility services have rights of redemption under C.R. S. § 38-39-103?
(2) Does the failure of a junior lienholder to exercise redemptive rights under C.R.S. § 38-39-103 at a public sale foreclosing on an undivided one-half interest in the property extinguish that lienholder’s redemptive rights in [754]*754subsequent foreclosure sales of the entire property?
This court has agreed to answer both interrogatories, and now answers “yes” to the first question and “no” to the second.
I.
Resolution of these questions requires careful consideration of the factual context in which they arose. J. James Patterson and Elizabeth S. Patterson were the owners of certain real property in Glenwood Springs, Colorado. This case involves three liens that attached to the property during the time it was owned by the Patter-sons. The senior lien was a first deed of trust given by the Pattersons to the public trustee for the use of Horace Mann Life Insurance Company (Horace Mann). This instrument was recorded1 on December 15, 1976. On March 4, 1982, J. James Patterson gave a second deed of trust on his undivided one-half interest in the property to the public trustee for the use of Valley Bank & Trust, which was recorded on March 17, 1982. The third relevant lien was created when the City of Glenwood Springs recorded a notice of lien against the entire property on February 2, 1983. This lien was for unpaid utility assessments in the amount of $176.07, and it arose pursuant to section 22-2 of the Glen-wood Springs Municipal Code.
The Pattersons were unable to meet the obligations secured by the deeds of trust, and the holders of the first and second deeds of trust commenced separate foreclosure proceedings. On May 4, 1983, a public trustee’s sale was conducted based upon the deed of trust held by Valley Bank & Trust on J. James Patterson’s undivided one-half interest. The plaintiff, John W. Sant, bid $19,260.00 and was issued a certificate of purchase for the undivided one-half interest by the public trustee. A second public trustee’s sale was held two days later on May 6, 1983, based upon the Horace Mann deed of trust on all interests in the property. Sant bid $26,369.00 and was issued a second certificate of purchase, covering the entire property.
On May 26, 1983, the City of Glenwood Springs assigned its lien to Edmund W. Roginski and Elisabeth D. Roginski.2 This assignment was recorded on July 20, 1983. On that same date, the last day of the period allowed by statute for the owners of the property to redeem from the Horace Mann foreclosure sale, the Roginskis filed a notice of intent to redeem the property from that foreclosure sale. The owners did not redeem, and no other lienor filed a notice of intent to redeem. On July 21, the Roginskis tendered $26,917.13 to the public trustee in order to exercise their right of redemption from the Horace Mann foreclosure sale as holders of a junior lien. The public trustee accepted this payment and on July 21 issued to the Roginskis a certificate of redemption and a public trustee’s deed for all interests in the property. The Roginskis then took possession of the property.
Neither the Roginskis nor any other junior lienors had filed a notice of intent to redeem or had exercised their rights of redemption in the Valley Bank & Trust foreclosure proceeding, and on July 27, 1983, the public trustee issued to Sant a public trustee’s deed to J. James Patterson’s undivided one-half interest.
Sant then requested that the public trustee issue a public trustee’s deed to the entire property based on his May 6, 1983, certificate of purchase arising from the Horace Mann lien foreclosure. When the public trustee refused, Sant brought a diversity of citizenship action in the United States District Court, pursuant to 28 U.S.C. § 1332 (1982), naming as defendants the Roginskis and Ella Stephens, the public trustee of Garfield County. Sant challenged the Roginskis’ redemption of the property and asked that Stephens be re[755]*755quired to vacate the certificate of redemption and the public trustee’s deed issued to the Roginskis and issue a public trustee’s deed in Sant’s favor based on the Horace Mann lien foreclosure. He also sought payment of his attorney fees, compensation for the rental value of the property during the time that the Roginskis occupied it, and punitive damages for clouding the title. The Roginskis filed an answer raising several affirmative defenses and asserting several counterclaims, including a claim to quiet title to the property. The Roginskis and Sant then moved separately for partial summary judgment to resolve the issues concerning their respective ownership rights in the property.
The United States District Court held a hearing on the motions and issued its order on December 16, 1983. Sant v. Stephens, 580 F.Supp. 1003 (D.Colo.1983). The court determined that the utility lien was valid and held that the Roginskis’ failure to redeem their interest from the Valley Bank & Trust foreclosure sale cut off their right to redeem from the Horace Mann sale. The district court ordered the public trustee to vacate the certificate of redemption and public trustee’s deed issued to the Roginsk-is and to issue a public trustee’s deed on all interests in the property in favor of Sant. The district court denied the Roginskis’ motion to alter or amend the judgment, and they appealed.3 The United States Court of Appeals for the Tenth Circuit determined that the decisions of the Colorado Supreme Court provided no controlling precedent on the issues presented by this case and certified two questions of Colorado law to this court.
II.
In order to answer the questions presented by this case, it is essential to understand the statutory provisions relating to rights of redemption. Article 39 of Title 38 of the Colorado Revised Statutes sets out the procedures governing redemption of real property from a sale under foreclosure or execution. When such a sale of lands is held, the purchaser of the property receives a certificate of purchase containing a statement that the purchaser will be entitled to a deed for the property at the expiration of all redemption periods if no redemption is made. § 38-39-115, 16A C.R.S. (1982). The owner of the property or “any person who might be liable upon a deficiency” has seventy-five days from the date of sale to redeem by paying the sum for which the property was sold plus interest from the date of sale and any taxes or other charges, § 38-39-102, 16A C.R.S. (1982), and such a redemption annuls the sale, § 38-39-105, 16A C.R.S. (1982).
If no redemption is made by the owner within this seventy-five day period, those holding encumbrances or liens on the property are given an opportunity to redeem. In order to exercise this right, the lienor or encumbrancer must have filed a notice of intent to redeem within the seventy-five day redemption period of section 38-39-102. § 38-39-103(1), (2), 16A C.R.S. (1982). Section 38-39-103(1) describes the redemption process for lienors:
If no redemption is made within the redemption period provided for in section 38-39-102, the encumbrancer or lienor having the senior lien, according to the records of the county clerk and recorder’s office of the county where the real estate is situate, on the sold premises or some part thereof subsequent to the lien upon which such sale was held may redeem within ten days after the expiration of the above redemption period by paying the amount required by section 38-39-102, and each subsequent encum-brancer and lienor in succession shall have and be allowed a five-day period to redeem, according to the priority of his lien, and may redeem within the five-day period allotted to him by paying all redemption amounts theretofore paid with interest and the amount of all such liens with interest prior to his own held by such persons as are evidenced in the manner required in this section or, if no [756]*756encumbrancer or lienor prior to himself has redeemed, by paying the amount required in section 38-39-102.
A redeeming lienor is issued a certificate of redemption which, when duly recorded, “operates as an assignment to him of the estate and interest acquired by the purchaser at the sale, subject, however, to the rights of persons who may be entitled subsequently to redeem.” § 38-39-105. After all redemption periods have expired, a deed “to the land and tenements sold” is issued to the holder of the certificate of purchase or to the lienor who last redeemed. § 38-39-110, 16A C.R.S. (1982). Section 38-39-110 provides in pertinent part:
Upon the issuance and delivery of such deed, but not until then, title shall vest in the grantee and such title shall be free and clear of all liens and encumbrances recorded or filed subsequent to the recording or filing of the lien on which the sale referred to in this section was based.
In construing these statutory provisions, it is important to remember that the right to redeem from an execution or foreclosure sale is “to be exercised in strict compliance with statutory terms” and “depends entirely upon the provisions of the statute creating the right.” Johnson v. Smith, 675 P.2d 307, 310 (Colo.1984). As this court observed more than half a century ago, “[t]he right to redeem is purely statutory and is not to be enlarged by judicial interpretation, yet a liberal construction is to be given the statute allowing redemption, to the end that all the property of a debtor may pay as many debts as possible.” Walker v. Wallace, 79 Colo. 380, 382, 246 P. 553, 553 (1926). See also First National Bank of Southglenn v. Energy Fuels Corp., 200 Colo. 540, 546, 618 P.2d 1115, 1119 (1980).
We turn now to the two interrogatories posed to us by the United States Court of Appeals for the Tenth Circuit.
III.
First Interrogatory:
Does a lien created by the City of Glen-wood Springs Municipal Code § 22-2 for unpaid utility services have rights of redemption under C.R.S. § 38-39-103?
We agree with the district court that Glenwood Springs has the power to enact an ordinance creating liens with rights of redemption. Sant v. Stephens, 580 F.Supp. at 1005. Glenwood Springs is a home rule city. See Colo.Const. art. XX; Charter of the City of Glenwood Springs. Article XX, Section 6, of the Colorado Constitution grants home rule cities “every power possessed by the General Assembly as to local and municipal matters,” unless these powers are restricted by the city’s charter. Service Oil Co. v. Rhodus, 179 Colo. 335, 344, 500 P.2d 807, 811 (1972). Accord Board of County Comm’rs v. City of Thornton, 629 P.2d 605, 609 (Colo.1981). In matters of purely local and municipal concern, an ordinance adopted by a home rule city supersedes a conflicting state statute. City of Greenwood Village v. Fleming, 643 P.2d 511, 515 (Colo.1982); Pierce v. City and County of Denver, 193 Colo. 347, 349, 565 P.2d 1337, 1338 (1977). In matters of both statewide and local concern, state statutes and municipal ordinances may coexist if they do not conflict. DeLong v. City and County of Denver, 195 Colo. 27, 31-32, 576 P.2d 537, 539-40 (1978). Accord Denver and Rio Grande Western Railroad Co. v. City and County of Denver, 673 P.2d 354, 358 (Colo.1983).
The parties in this case disagree as to the nature of the Glenwood Springs ordinance. However, so long as the ordinance involves matters of local concern, even if they may also be of statewide concern, and does not conflict with a state statute, it is not superseded by state enactments. There can be no doubt that the collection of charges for utility services provided by a municipality is a matter of local concern. Therefore, even if it also involves some matters of statewide concern, the ordinance is valid absent a conflict with a state statute. In determining whether two pieces of legislation conflict, the critical inquiry is “whether the ordinance authorizes what the state forbids, or forbids what the state has expressly authorized.” Aurora v. Martin, 181 Colo. 72, 75, 507 [757]*757P.2d 868, 869-70 (1973). We have discovered no state statute that prohibits a home rule city from creating liens to secure utility charges or from providing that such liens shall have redemption rights like those accorded to many other classes of liens. We agree with the district court that the Glenwood Springs ordinance does not conflict with any state statute.
The district court did not expressly rule that a lien created pursuant to section 22-2 includes the redemption rights specified in section 38-39-103, 16A C.R.S. (1982). Sant argues that not all liens have rights of redemption under section 38-39-103, and contends that the lien created by section 22-2 does not incorporate such redemption rights. Since the Roginskis purported to redeem the property in accordance with section 38-39-103, Sant asserts, their redemption of the property was invalid.
The City of Glenwood Springs provides utility services to its residents, and Municipal Code section 22-2 allows the city to assess a lien for utilities services on the property served “[i]f charges for electricity, water, sewer, garbage, trash and waste material pick-up service, or any combination of these, remain unpaid for thirty (30) days after payment is due_” The ordinance sets out the notice and review procedures the city must follow before such a lien can be assessed. Sant does not suggest that the city failed to follow these procedures in this case.
Section 22-2(b) provides in pertinent part:
The lien shall then be certified to the county treasurer with instructions to collect the lien in the same manner as general taxes are collected and assessed against the subject property. To collect the lien, the city may avail itself of the laws and of liens [sic], including laws for the sale and redemption of property for nonpayment. Without limiting the foregoing, the city may bring an action in a court of law to collect all unpaid arrear-ages for utilities service.
Sant argues that this ordinance authorizes the city to collect utility arrearages in the same manner as general taxes are collected and assessed and characterizes the liens imposed thereunder as liens for the assessment of taxes. Section 38-39-114, 16A C.R.S. (1982), provides that Article 39, which includes section 38-39-103, relating to lienors’ rights to redeem from foreclosure sales, “shall not apply to statutory liens of taxes.” Sant contends that this provision expressly excludes liens such as those imposed under section 22-2 from the coverage of section 38-39-103.4 However, we reject Sant’s analysis. Section 22-2 authorizes the creation of a lien for unpaid utility charges for services supplied by the City of Glenwood Springs. This utility lien is not a “statutory lien of taxes,” such as liens for property taxes, created pursuant to section 39-1-107, 16B C.R.S. (1982 & 1987 Supp.), which have priority over all other liens until the taxes have been paid in full. See also §§ 39-22-604(7), 16B C.R.S. (1982) (withholding taxes); 39-26-117, 16B C.R.S. (1982) (sales taxes); 39-26-205, 16B C.R.S. (1982) (use taxes). Property tax liens are governed by specific provisions relating to the sale of property for unpaid taxes and redemption from tax sales. See §§ 39-11-101 to -151; 39-12-101 to -113, 16B C.R.S. (1982). Since the ordinance creates a lien for utility charges rather than for taxes, section 38-39-114 does not foreclose the application of section 38-39-103.
Sant also points out that section 38-39-103 does not expressly provide that a lien such as that created pursuant to section 22-2 possesses redemption rights. How[758]*758ever, the provision does not define the types of liens covered. Instead, the statute refers broadly to “encumbrancer[s] or lien- or[s],” providing them with the right to redeem from a foreclosure or execution sale. The right to redeem has not been limited to holders of mortgages or deeds of trust. In Twogood v. Ocsay, 97 Colo. 300, 49 P.2d 437 (1935), this court determined that the right to redeem from a foreclosure or execution sale extends to judgment lien-ors. See also First National Bank of Southglenn v. Energy Fuels Corp., 200 Colo, at 543-44, 618 P.2d at 1117. Similarly, in Dolan v. Flett, 41 Colo.App. 40, 582 P.2d 694 (1978), the Colorado Court of Appeals rejected an attempt to limit the concept of “lienor” embodied in section 38-39-103 and determined that the holder of an attorney’s lien that has not been reduced to judgment is entitled to redeem in accordance with section 38-39-103.
Moreover, the language in section 22-2(b), although somewhat ambiguous, demonstrates an intent to incorporate redemption rights into liens created thereunder. The provision regarding the collection of liens “in the same manner as general taxes are collected” simply describes one method for collecting the utility charges.5 The ordinance also specifies two other procedures for collection of the secured charges. The city may collect the unpaid utility charges by availing itself of the general laws relating to liens, including laws for the sale and redemption of property subject to the lien. Alternatively, the city may institute civil proceedings to collect unpaid arrearages. The ordinance adequately states that the utility liens created thereunder carry redemptive rights, and the language of the ordinance should be given effect.6 Therefore, the answer to the first question of law posed by the Tenth Circuit Court of Appeals is “yes.”
IV.
Second Interrogatory:
Does the failure of a junior lienholder to exercise redemptive rights under C.R.S. § 38-39-103 at a public sale foreclosing on an undivided one-half interest in the property extinguish that lienholder’s redemptive rights in subsequent foreclosure sales of the entire property?
The district court determined that the issuance of the public trustee’s deed to Sant in the Valley Bank & Trust foreclosure cut off the rights of all lienors who could have redeemed from the sale, even though that sale involved only an undivided one-half interest in the property. Since the Roginskis failed to redeem from the Valley Bank & Trust foreclosure sale, the court held, their rights in the entire property were extinguished, and a public trustee’s deed to the entire property should have been issued to Sant based upon the certificate of purchase he obtained at the Horace Mann foreclosure sale.
The decision relied on the language of section 38-39-110, which provides that issuance of a public trustee’s deed to the holder of a certificate of purchase cuts off all liens recorded or filed subsequent to the recording or filing of the lien on which the sale was based. As the district court interpreted this language, the issuance of a public trustee’s deed extinguished the entire rights of all lienors who had been entitled to redeem but did not exercise their rights to do so. The court expressed the view that requiring all junior lienors to participate in the redemption process in order to preserve their interests is consist[759]*759ent with the policies underlying the redemption statute:
This rule encourages participation in the redemption process, thereby maximizing the price obtained upon sale. Moreover, this rule leaves no confusion about the rights of subsequent lienors following the issuance of the trustee’s deed and therefore protects the value of the property interest obtained upon purchase or redemption.
Sant v. Stephens, 580 F.Supp. at 1007. The court also stated that it declined to sanction a procedure which could allow the Roginskis to make a conscious decision not to redeem from the first sale, since, they knew that the sale on the superior lien was pending, and still retain the right to redeem from the second sale. The decision stated that such “speculation” was contrary to the intent of the redemption statutes. 580 F.Supp. at 1007 n. 5.
Sant contends that the approach adopted by the district court is correct. He asserts that the language of section 38-39-103(1), which states that a junior lienor with a lien on “the sold premises or some part thereof ... may redeem,” provides all junior lien-ors holding any interests in the property with redemptive rights that must be exercised to preserve such interests. According to Sant, the Roginskis had an obligation to exercise their redemption rights at the first sale and since they did not, their interest in the entire property was cut off. Sant emphasizes that the Roginskis held only one lien covering the entire property and contends that the Roginskis are trying to divide this single lien into individual liens on the Pattersons’ undivided one-half interests with separate rights of redemption. He argues that this is impermissible, since a lien is a single, non-divisible interest. See, e.g., Warren v. Ellison, 250 Ala. 484, 35 So.2d 166, 168 (1948) (“the mortgage debt is a single entity”); Springer Corp. v. Kirkeby-Natus, 80 N.M. 205, 453 P.2d 376, 379 (1969) (“a mortgage is an entire thing, and must be redeemed in its entirety”); 9 G. Thompson, Commentaries on the Modem Law of Real Property § 4829 (1958). However, these cases establish only that a lienor holding a lien on an undivided interest must still redeem all interests in the property when the entire property is the subject of the foreclosure sale, and do not support Sant’s position.
We reject the rule developed by the district court for several reasons. First, we note that the district court misconstrued section 38-39-110. Section 38-39-110 provides for the delivery of a deed “to the land and tenements sold,” which conveys title free of all liens subsequent to the one on which the sale is based. Thus, a foreclosure sale discharges liens only with respect to the interests sold. Since the Valley Bank & Trust sale involved only J. James Patterson’s undivided one-half interest, the deed issued could not affect liens on Elizabeth S. Patterson’s undivided one-half interest.
In addition, the approach adopted by the district court and urged by Sant is contrary to general principles of cotenancy. Although the record does not indicate whether the Pattersons held title as joint tenants or tenants in common, the distinction is not important here. Under fundamental concepts of property law, “[e]ach tenant in common holds his interest and his title independently of the other coten-ants — ” 4 G. Thompson, Commentaries on the Modem Law of Real Property § 1793 (1979). Similarly, “[o]ne joint tenant cannot alienate the interest of the other joint tenants or in any way affect such interests.” Id. at § 1780. Thus, it is clear that the interests of J. James Patterson and Elizabeth S. Patterson are distinct, and action taken as to J. James Patterson’s interest does not affect that of Elizabeth S. Patterson. In First National Bank of Southglenn v. Energy Fuels Corp., this court pointed out that a creditor with a lien against one joint tenant has no right to attach the interest of the other joint tenant, and that “[t]he real property interest of two joint tenants cannot be used to satisfy the judgment creditor of one joint tenant.” 200 Colo, at 545, 618 P.2d at 1119. The district court’s holding in this case requires a lienholder on all interests in the property to redeem from a sale of an undivided interest, and this essentially uses the inter[760]*760est of two cotenants to satisfy the creditor of one.
The rule developed by the district court is also contrary to the rationale of the decision of this court in First National Bank of Southglenn v. Energy Fuels Cory., a case in which we considered the meaning of section 38-39-103 and the purposes underlying Colorado’s redemption statutes.7 Energy Fuels involved real property owned in joint tenancy by a husband and wife. Energy Fuels Corporation held a judgment lien against the husband, while First National Bank of Southglenn was the beneficiary of a deed of trust junior to the Energy Fuels lien but encumbering the interests of both cotenants. Both lienors sought to redeem the property from a foreclosure sale of a senior deed of trust. We noted that Energy Fuels’ lien attached only to the husband’s undivided interest in the property, while Southglenn Bank’s lien attached to both the husband’s and the wife’s interests, and concluded:
Therefore, we hold that no liens existed on [the wife’s] interest prior to Sou-thglenn Bank, and Southglenn Bank may redeem her interest in the property without paying the amount of [the husband’s] debt to Energy Fuels.
200 Colo, at 544, 618 P.2d at 1118. This holding establishes that a lien attaching to the interests of both cotenants carries distinct redemptive rights as to each interest. Therefore, the Roginskis’ failure to redeem from the first foreclosure sale, which covered only the interest of J. James Patterson, did not extinguish their lien on Elizabeth S. Patterson’s undivided one-half interest.
Since their lien on the interest of Elizabeth S. Patterson was not extinguished by their failure to redeem from the first sale, the Roginskis assert that they were entitled to redeem the entire property.8 In Walker v. Wallace, 79 Colo. 380, 246 P. 553 (1926), this court held that the holder of a lien on an undivided interest in real property was entitled to redeem the entire property from a sale in foreclosure of a prior lien on the whole. See also Leach v. Torbert, 71 Colo. 85, 204 P. 334 (1922). In fact, a holder of a lien on an undivided interest who wished to redeem was obligated to redeem the entire property. Walker v. Wallace, 79 Colo, at 385, 246 P. at 554-55. Our decision noted that the redemption statute then in effect did not allow for partial redemption by such a lienholder. We reasoned that to allow a holder of a lien on an undivided interest to redeem the entire property would further the policies underlying redemption statutes by using the property “to pay as many debts of the judgment debtors and each of them as is possible_” 79 Colo, at 385, 246 P. at 555. See also Chain O’Mines, Inc. v. Williamson, 101 Colo. 231, 72 P.2d 265 (1937).
The rule announced in Walker v. Wallace was modified by this court in First [761]*761National Bank of Southglenn v. Energy Fuels Corp. In Energy Fuels we acknowledged the holding of Walker v. Wallace that a lienholder on an undivided interest in property has the right to redeem the entire property but found important differences between the case then before us and Walker v. Wallace:
The applicable redemption statute in 1926 was markedly different from section 38-39-103(1), C.R.S. 1973. Also, Walker concerned only one creditor seeking to redeem. This case involves competing lienholders who each possess a superior lien on separate interests of real property held in joint tenancy.
200 Colo, at 546, 618 P.2d at 1119 (footnote omitted). We noted that the rule in Walker v. Wallace would still apply to situations similar to that case, stating that “[i]f Energy Fuels had been the only lienor seeking to redeem or the only person with the right to redeem, it could redeem the whole property.” 200 Colo, at 544, 618 P.2d at 1117.
As in Energy Fuels, the present case involves “competing lienholders who each possess a superior lien on separate interests of real property” held by cotenants. 200 Colo, at 546, 618 P.2d at 1119. Sant was the purchaser at the foreclosure sale based on the Valley Bank & Trust deed of trust, and thereby obtained the superior lien on J. James Patterson’s interest, while the Roginskis held the superior lien on Elizabeth S. Patterson’s interest. The lesson of Energy Fuels is that the Roginskis’ lien must be considered to be divisible for redemption purposes in such circumstances. The decision of the Ro-ginskis not to redeem from the sale of J. James Patterson’s undivided one-half interest did not render their lien on Elizabeth S. Patterson’s undivided one-half interest subject to extinguishment when the public trustee’s deed issued on the Valley Bank & Trust foreclosure sale. Based upon their lien, the Roginskis elected to redeem from the foreclosure sale of the entire property under the Horace Mann deed of trust. Unlike the facts in Energy Fuels, the Ro-ginskis were the only lienors seeking to redeem from that sale. Therefore, based upon their lien on the undivided one-half interest of Elizabeth S. Patterson, the Ro-ginskis had the right to redeem the entire property from the sale. Energy Fuels, 200 Colo, at 544, 618 P.2d at 1117; Walker v. Wallace, 79 Colo, at 385, 246 P. at 554-55. A contrary result would mean that the holder of a lien on the entire property would be required to redeem from a foreclosure sale of an undivided interest in that property or face the consequence of extin-guishment of the lien on the entire property. This would in essence violate the principle stated in Energy Fuels, in terms based upon the facts of that case, that “[t]he real property interest of two joint tenants cannot be used to satisfy the judgment creditor of one joint tenant.” 200 Colo, at 545, 618 P.2d at 1119.9
As a result of our analysis, we answer “no” to the second question of law posed by the Tenth Circuit Court of Appeals.
QUINN, C.J., dissents in part, and ROVIRA, J., joins in the partial dissent.
