delivered the opinion of the court:
This сase concerns the application and constitutionality of section 7 of “An Act relating to mortgages ***” (Ill. Rev. Stat. 1979, ch. 95, par. 57), which permits a mortgagor to reinstate a delinquent mortgage upon payment of the amount of delinquency and costs within 90 days of summons in the foreclosure action but prior to a final order of forеclosure. A mortgagor may cure his delinquency under the terms of the statute only once in a five-year period. In an action brought by First Federal Savings and Loan (plaintiff) to foreclose its delinquent mortgage on defendants’ home, which had been twice reinstated under this statute within the preceding two years, the circuit court of Cook County held that, by limiting the frequency with which the statute could be used, the legislature had unconstitutionally limited the inherent equitable powers of the court. Furthermore, the court held that First Federal, by allowing the second reinstatement of the mortgage, had waived its right to invoke the statute’s once-in-five-years limitation in the third foreclosure action. First Fеderal appeals directly here under Rule 302(a)(1) (73 Ill. 2d R. 302(a)(1)).
The procedural posture of this cause is unusual because defendants filed no pleadings in the circuit court, and both the issues of waiver and constitutionality were raised by the trial court sua sponte. Defendant Editha Walker appeared pro se at most of the many hearings in this matter extending over a 12-month period. After repeated urgings by the court, she obtained counsel from the Legal Assistance Foundation and was represented at the last two hearings. Her husband, Russell Walker, entered a pro se appearance but did not thereafter attend the hearings. The couple was divorсed during the course of the proceedings, and Editha was awarded the home. Editha Walker’s attorneys, in response to the circuit court’s request, filed a memorandum of law on the constitutionality of the statute, which concluded, as did the court, that the statute invaded the equitable powers of the court and violated the equal protection and due process clauses of the Illinois and United States constitutions, as well as the special legislation clause of the Illinois Constitution.
The record indicates that at various times in open court Editha Walker tendered sums to First Federal in partial satisfaction of the delinquency. At one point the tendered sum аpparently equaled the total amount of the delinquency but did not include the costs and attorney fees which the statute requires in order to reinstate. First Federal consistently refused the tendered payments and insisted on its right to foreclose. In its order, which found that the statute was unconstitutional and that First Federal had waived its right to foreсlose, the court ordered that the mortgage be reinstated and that Editha Walker pay into court the delinquent sum and future installments as they became due. Attorney fees were determined to be $1,000, but no order was entered concerning payment.
Editha Walker moved to dismiss this appeal on mootness grounds, and we took the motion with the case. It is stated by her in support of the motion that should the Federal court in her presently pending bankruptcy proceedings refuse to approve a plan submitted to it, she could not meet her obligations under the mortgage. Conversely, if the bankruptcy court approves a plan, the constitutionality of the statute is irrеlevant, for the bankruptcy plan will be controlling. It seems clear, however, that neither conclusion necessarily follows. The validity of the statute could conceivably be a factor in the bankruptcy court’s consideration of the case before it, and the Walkers’ financial situation could conceivably change between the date of the motion and future trial court proceedings. Consequently, the motion to dismiss is denied.
The trial court’s conclusions that the statute is unconstitutional on due process and equal protection grounds and constitutes special legislation are without merit. Prior to adoption of the reinstatement statute, a mortgagor had, and retains, a statutory right to redeem his property from foreclosure and sale (Ill. Rev. Stat. 1979, ch. 77, par. 18), although that procedure is more costly and apparently not often used by homeowners. (Illinois Legislative Review: Foreclosures, Redemptions, and Homeowners, 1975 U. Ill. L. F. 335, 339, 351-52.) The right to reinstate a delinquent mortgage was unknown to the common law and is purely statutory. (State Farm Life Insurance Co. v. Town & Country Association (1980),
The circuit court’s conclusion that the once-in-five-years limitation impermissibly interferes with the inherent pоwers of a court of equity misconceives both the nature of this remedy and the court’s power. As earlier noted, the right to reinstate a delinquent mortgage did not exist at common law, and when a mortgagor defaulted in his payments on a mortgage which provided, as here, for acceleration of the entire debt upon defаult, he could redeem the mortgage prior to the order of foreclosure and sale only by paying it in full. (E.g., Curran v. Houston (1903),
Apparently, however, the trial court viewed the statute as enlarging its equitable powers by authorizing reinstatement but unconstitutionally invading those enlarged powers by limiting the use of the provision. The statute, however, created a substantive right unknown at common law, and the time limitation on its use is obviously an integral part of that right. As such it neither expanded nor contracted the equitable powers of the court (see Smith v. Toman (1938),
“We do not know of аny power existing in a court of equity to dispense with the plain requirements of a statute; it has been always disclaimed, and the real or supposed hardship of no case can justify a court in so doing. When a statute has prescribed a plain rule, free from doubt and ambiguity, it is as well usurpation in a court of equity as in a court of law, to adjudge against it; and for a court of equity to relieve against its provisions, is the same as to repeal it.”

People ex rel. County Collector v. Jeri, Ltd. (1968),
We find no evidence that First Federal has waived its right to proceed to foreclosure. Both the mortgage instrument and the note which it secures provide that a waiver of a term on one occasion is not to be considered a wаiver of that term on subsequent occasions. According to the undenied allegations of First Federal’s motion for summary judgment, Walkers’ mortgage was reinstated by court order under the terms of the statute on December 15, 1978, and again on August 31, 1979. After a third default in December 1979 First Federal filed this action in January 1980. While the record does not indicate the extent to which First Federal opposed the second reinstatement, the trial court seems to have believed there was no opposition and held that by permitting the second reinstatement First Federal had waived its right to invoke the five-year limit on the statute’s use in this action, and that defendants had relied upon the right to reinstate a third time. A waiver is the intentional relinquishment of a known right, and the burden of proof is upon the party claiming waiver. (Ferrero v. National Council of Knights & Ladies of Security (1923),
Because defendants have filed no pleadings it would appear that plaintiff is entitled to the relief sought, unless precluded by the pending bankruptcy proceedings. Accordingly, we reverse the judgment of the circuit court of Cook County and remand the cause to that court with directions to proceed consistently with this opinion to the extent such action is not incompatible with action taken by the bankruptcy court.
Reversed and remanded, with directions.
