This is an action to recover a judgment for some unpaid instalments of rent. The complaint alleged that under the provisions of a lease the defendant promised to pay a gross rental of $4,800 in instalments of $80 per month for the period of November 15, 1924, to November 15, 1929, and that the instalments due April *Page 671 15, 1928, and May 15, 1928, had not been paid; judgment for the sum of $160 was demanded. Attached to the complaint as an exhibit is a copy of the lease. The only denial contained in the answer denied "that defendants or either of them are indebted in the sum of, or owe the plaintiff the sum of $160, or any other sum, or at all"; affirmatively it alleged a rescission of the lease and also circumstances which the defendants alleged constituted an estoppel. Before trial the court permitted the plaintiff, over the defendants' objections, to file a supplemental complaint, which alleged nonpayment of rent for the months of June to December, 1928, both inclusive. After the plaintiff had established by proof the controverted portions of its complaint as supplemented, and the defendant had failed to prove its allegations of a rescission and of an estoppel, the court below directed the jury to return a verdict "in favor of the plaintiff and against the defendants and each of them in the sum of $800." The jury having done so, a judgment was entered in the plaintiff's favor for the aforementioned several instalments of rent, including interest upon each at the rate of 6 per cent from the time when each instalment became due and payable. The defendant has appealed and assigns as error the order of the circuit court which permitted the filing of the supplemental complaint and the allowance of interest.
AFFIRMED. REHEARING DENIED. It will be observed from the foregoing statement of facts that the rent for which plaintiff seeks judgment was payable under a written lease which stipulated for a gross sum of $4,800, payable *Page 672 in monthly instalments. From Clark on Code Pleading, p. 327, we quote: "On instalment contracts a like rule applies, namely that successive suits may be brought as each instalment falls due, but all instalments due at the time suit is brought must be claimed or are waived. The rule has been applied to various forms of such contract, including rent under a lease. * * *" To same effect see 1 R.C.L., Actions, § 31. § 108, O.L., authorizes the filing of a supplemental complaint "alleging facts material to the case, occurring after the former complaint." The purpose of the supplemental pleading is to bring into the record new facts, which will enlarge or change the kind of relief to which the plaintiff is entitled, and hence any supplemental facts which further develop the original right of action, or extend or vary the relief, are available by way of supplemental complaint, even though they of themselves constitute a right of action: 21 Enc. of Pl. and Pr. 18 and Phillips on Code Pleading, § 317. Whether a party should be permitted to file a supplemental pleading rests largely in the discretion of the trial court: Clark on Code Pleading, 523, 21 R.C.L., Pleading, § 68. The above being the purpose served by a supplemental pleading the circuit court was fully justified in making the order complained of. The following authorities, we believe, support our conclusion: Jordan v.Indianapolis Water Co., 159 Ind. 337 (64 N.E. 68); Pickerill v.Home Realty Co., 79 Ind. App. 47 (136 N.E. 850); Sigler v.Gondon, 68 Ia. 441 (27 N.W. 372); Knapp v. Order of Pendo,36 Wash. 601 (79 P. 209). The textbooks state that such after-maturing instalments may be made a part of the cause of action by supplemental pleading: Bancroft's Code Pleading, § 459, 36 C.J., Landlord and Tenant, § 1345, p. 425; 24 Enc. of Procedure, p. 533; Phillips on Code Pleading, § 318. Bull v.Rothschild, *Page 673 16 N Y Civ. Proc. 356, relied upon by the defendants, supports their position, but we believe that it is opposed to the spirit of code pleading and fails to recognize the purpose of a supplemental pleading; we decline to follow it.
The court did not err when it entered a judgment allowing 6 per cent interest upon each instalment from its maturity. § 7988, O.L., provides for the recovery of interest at the rate of 6 per cent per annum upon "all moneys after the same became due." The plaintiff established by uncontroverted evidence its claim and the lease fixed the dates upon which each instalment of rent became due and payable. The following taken from 27 R.C.L., Verdict, § 63, is well supported by the authorities, which have passed upon situations similar to that before us:
"* * * Even when no mention of interest is made in the verdict, but it is clearly apparent that the prevailing party is entitled to interest on the amount found in the verdict, and it is unquestionably clear that the jury allowed no interest, or where the court reserved the question of the allowance of interest until after verdict, and the dates from which and to which interest should be allowed are clearly ascertainable from the verdict or uncontroverted facts, and the rate is fixed, the court may make the computation and add the interest so found to the sum found in the verdict, and render judgment for the aggregate amount."
The verdict was a directed one; the complaint prayed for interest from specified dates; the matter of determining interest was a mere matter of computation; the plaintiff's right to it is clear. We conclude, therefore, that the court was fully justified in rendering the judgment which allowed it.
The judgment appealed from will be affirmed.
AFFIRMED. REHEARING DENIED.
