— Plaintiff Nettie Brinton and appellant Jessie Winter Brown were the daughters of Judge Thomas H. Parrish and Susan A. Parrish. At the time of his death which occurred in 1897, Judge Parrish was judge of the circuit court of Buchanan county. His widow and his said daughters were his sole survivors. He left personal property, including life insurance, of the value of about six thousand dollars and a homestead in St. Joseph, all of which he devised by his will to his widow. Mrs. Parrish died intestate at Tipton, Moniteau county, November 19, 1907, leaving her said daughters her sole heirs. Her estate consisted of personal property valued at about four thousand dollars and the real estate in St. Joseph left by her husband. From July, 1901, to the day of her death, Mrs. Parrish lived with the Brinton family and her son-in-law, T. J. Brinton, acted as her agent in business affairs. In 1902, while living with the Brintons at Kansas City, she suff fered a stroke of apoplexy accompanied by paralysis of her left side and, thereafter, to her death, was an in*69valid. After her death, letters of administration were issued by the probate court of Moniteau county to A. J. Thomas who qualified as administrator and took charge of her estate. Among her papers, the administrator found a promissory note of $8,059.60, dated March 18, 1907, executed to Mrs. Parrish by plaintiff T. J. Brinton. This action was begun in the probate court of Moniteau county by plaintiffs T. J. and Nettie Brinton on the following demand:
“The Estate of Susan A. Parrish, deceased, “To T. J. Brinton and Nettie Brinton, Dr.:
“To board, washing, &c., for 26 weeks, from July 1st, 1901, to January 18th, 1902, at $4.00 per week..................$ 104.00
“To board, washing, nursing and care of said Susan A. Parrish, while a helpless invalid, from January 18th, 1902, to . November 19,1907, being five years and ten months, or 306 weeks at $25.00 per week............................ 7,650.00
“To two tickets to St. Joseph and one ticket to return......................... 10.95
$ 7,764.95
“Credit by note dated March 18th, 1907, payable to Mrs. Ann Parrish, signed by T. J. Brinton, for balance due.......... 3,059.60
“Balance due..................$ 4,705.35”
No answer was filed in the probate court but the allowance of the demand was resisted by Mrs. Brown, the remaining heir. Plaintiffs were successful in that court and Mrs. Brown appealed to the circuit court where the cause was tried to a jury at the May term, 1908. The verdict returned May 7th was “for the defendant in the sum of three thousand forty-eight *70($3,048.65) dollars and sixty-five cents.” On the same day, the court entered judgment on this verdict as follows: “It is therefore by the court ordered, adjudged and decreed that the defendant A. J. Thomas, administrator of the estate of Susan A. Parrish, deceased, have and recover of the plaintiff, T. J. Brinton, the sum of three thousand forty-eight 65.100 dollars ($3,048.65) and have execution therefor,' and further that said administrator have and recover from the plaintiffs the costs in the case and have thereof execution.”
On the next day at the same term of court plaintiffs filed a motion for a new trial, assigning a number of errors as grounds for the relief asked. On August 1st following, and during an adjourned session of the May term, Mrs. Brown filed a motion to correct the judgment, the object of the movant being to have judgment rendered in favor of the administrator against Mrs. Brinton as well as against her husband, T. J. Brinton. This motion and the motion of plaintiffs for a new trial were taken under advisement until the following term of court. At that term, the court sustained Mrs. Brown’s motion and rendered the following judgment: “It is therefore by the court ordered, adjudged and decreed that the defendant, A. J. Thomas, administrator of the estate of Susan Ann Parrish, deceased, have and recover of the plaintiffs, T. J. Brinton and Nettie Brinton, the sum of three thousand forty-eight 65-100 dollars ($3,048.65) and the costs in the case, and have thereof execution.”
. The proceedings following the rendition of this judgment thus are stated in the record: “That, thereafter, towit, the said 8th day of September, 1908, the plaintiffs, by their counsel, leave of court first had and obtained, amended their motion for a new trial heretofore filed in this cause, which amended motion for a new trial is as follows, towit: *71grant them a new trial, for the following reasons: First- — Because the verdict is against the law as declared by the court. Second — Because the verdict is against the evidence and against the weight of the evidence. Third — Because instructions numbered — and — given by the court at request of appellant against the objection of plaintiffs are incorrect. Fourth — Because the verdict of the jury against the plaintiffs not allowing them anything for six years’ service in boarding, nursing and caring for deceased, shows said verdict to be the result of bias and prejudice on the part of the jury against the plaintiffs. Fifth — Because M'r. Gabbert, attorney for appellant, in his opening statement to the jury, stated to them that the offset to plaintiff’s demand, consisting of a note given by the plaintiff, T. J. Brinton to deceased, was made up of checks forged by T. J. Brinton, which was untrue, and was not an issue in said cause, and had a tendency to and did prejudice the jury against the plaintiffs. Sixth — Because said Gabbert, on numerous occasions, during the progress of the trial, referred to said note and set-off as consisting of moneys of the deceased, which had been drawn on forged checks or orders, all which references were contrary to the rulings of the court and had a tendency to, and did prejudice the minds of the jury against the plaintiffs. Seventh- — Because, during the trial of this cause, one — Brown, the husband of appellant, living in St. Joseph, filed an affidavit there, on which a warrant was issued against the plaintiff, T. J. Brinton, on which warrant an officer of that city arrested said plaintiff during the trial of the cause, for the sole purpose of creating a sentiment against the plaintiffs. Eighth — Because it has come to the knowledge of plaintiffs’ counsel, since the trial of said cause, that deceased had distributed a considerable amount of her estate prior to her death, which -was not known to them prior to the trial, but was known to the appellant, who was a distributee and which accounts in large measure for the shrinkage *72of said estate, which fact was largely dwelt upon by counsel for appellant in his argument to the jury. Ninth — Because upon the law and the evidence, the verdict should have been for the plaintiffs. Tenth — Because the court erred in rendering a verdict against the plaintiff, Nettie Brinton, for the amount of the note of T. J. Brinton to Ann Parrish, to which note she was not a party.”
*70“Come now the plaintiffs and move the court to set aside the verdict of the jury in the above cause and
*72“And now here on said 8th day of September, 1908, during the regular September, 1908, term, the plaintiffs, by their counsel, leave of court first had and obtained, refile in said cause their motion for a new trial herein as amended.”
The amendment to the motion consisted of the addition of the tenth ground which related to the alleged error of the court in rendering judgment against Mrs. Brinton for the amount of her husband’s note. No objection was interposed by appellant to any of these proceedings. Afterward, the court sustained plaintiff’s motion for a new trial on the following grounds: “Because of offers of testimony irrelevant and prejudicial which affected the minds of the jury and because counsel for the defendant referred in the course of the trial to alleged forgeries committed by one of the plaintiffs, which was irrelevant and prejudicial and because the verdict of the jury is against the testimony and the weight of the testimony, and because the judgment as rendered by the court is unwarranted by the evidence and the pleadings.”
Mrs. Brown brought the cause here by appeal from the order granting a new trial. Appellant contends there was no motion for a new trial before the court. She argues that the. amended motion was ineffective as it was not filed within four days after the.trial but was filed at a subsequent term, and that in attempting to amend the original motion, which was filed in proper time, ana in refiling it as an amended motion, the original was abandoned and could not serve as a foundation for the *73order granting a new trial. This argument is more ingenious than just and sound and when analyzed the inconsistency of its propositions becomes apparent. Appellant would treat the amended motion as a nullity for one purpose and as a vital thing for another purpose. As a motion for a new trial, she contends it is void because filed out of time, but that it is good for the purpose of superseding the original motion. It would be a reproach on the administration of justice should we turn a party out of court on such reasoning. The statute provides, section 803, Revised Statutes 1899:
“All motions for new trials and in arrest of judgment shall be made within four days after the' trial, if the term shall so long continue and if not, then before the end of the term.” It is well settled that this statute is mandatory and that neither a motion for a new trial nor an amendment thereto may be filed after the expiration of four days from the verdict. [Bank v. Porter, 148 Mo. 176; Mirrielees v. Railway, 163 Mo. 470.]
When the statutory period expired, plaintiffs had no right to file an amended motion or to amend the original, nor did the court possess any discretion in the matter. It had no authority to make an order allowing an amendment nor to permit the refiling of the motion. [Scott v. Joffee, 125 Mo. App. 573.] The entire proceeding was non-jurisdictional and void for any purpose. The rule that treats an amended pleading as a complete substitute for the original has no application here. Where the law permits pleadings to be amended, the filing of the amended pleading necessarily should be regarded as an abandonment of the original, but where the law does not suffer an amendment to be made, an amended pleading being impotent as a substitute logically should be accorded no displacing functions. We conclude the original motion afforded a legal foundation for the order granting a new trial.
One of the reasons assigned by the court for granting a new trial was that the verdict was against the *74weight of the evidence. Not only is it the right, but it is the duty of the trial judge to act as the final trier of fact and where on weighing the evidence, he becomes convinced that the verdict is not supported by the weight of the evidence, he should prevent the accomplishment of injustice by setting it aside.
Appellate courts appreciate the advantages of the position of the trial judge, derived from the confrontment of parties and witnesses, and do not undertake to control him in the exercise of this important function unless it clearly appears that he has abused his right, has not exercised 'discretion, but has acted arbitrarily or oppressively. Consequently, when the record discloses that the action of the court in setting aside the verdict on the ground under consideration is supported by substantial evidence and that the evidence will permit a reasonable mind to indulge in the conclusion reached by the court, his exercise of discretion will not be disturbed. [Richardson v. Brick Co., 122 Mo. App. 529; McCarty v. Transit Co., 192 Mo. 396; Young v. Ruhwedel, 119 Mo. App. 231; Herndon v. Lewis, 175 Mo. 116.]
Appellant does not controvert this rule, but does insist that the demand of plaintiffs is not supported by substantial evidence. The evidence adduced by plaintiffs tends to show that Mrs. Parrish was a helpless invalid requiring constant attention; that plaintiffs supported her and cared for her in a manner to earn her approbation and gratitude and while there is no evidence of an express contract, there is evidence that there was a mutual understanding and intention that the services were not to be gratuitously rendered but were to be reasonably compensated by the recipient. It did not devolve on plaintiffs to prove an express contract in order to support their demand. A contract for reasonable compensation should be implied from the fact that services were rendered under an agreement or mutual understanding that they were not gratuitous but were to be paid for. There is much in the evidence to impress a reasonable *75mind with the belief that the services were not accepted by Mrs. Parrish as services for reward but were regarded by her as the response on the part of plaintiffs to the promptings of filial duty and affection. [Kostuba v. Miller, 137 Mo. 161.] But there is also room in the evidence for the opposite conclusion, and for the reasons above stated we defer to the judgment of the trial judge who faced the parties and witnesses and whose duty it was to weigh the evidence.
The fact that plaintiff, T. J. Brinton, gave Mrs. Parrish a note for money he owed her at the time when plaintiffs claim Mrs. Parrish owed them jointly a sum in excess of the amount of the indebtedness is a fact to be considered by the triers of fact, but by no means is it to be taken as conclusive proof of the absence of an understanding on the part of Mrs. Parrish to pay for the services. We think there is not an improper joinder of parties plaintiff. The evidence of plaintiffs shows that the services rendered by husband and wife were about in equal parts. They were jointly rendered and it was proper for plaintiffs to join in an action for the recovery of compensation for them. [Lillard v. Wilson, 178 Mo. 145.]
What we have said disposes of the appeal adversely to the contention bf appellant, but in view bf a retrial of the action, other points should be decided.
In admitting the indebtedness of T. J. Brinton to the estate, evidenced by the note he gave Mrs. Parrish, plaintiffs removed that indebtedness from the debatable issues of the case and the judge was right in refusing the offer made by appellants which tended to show how that indebtedness originated. Counsel for appellant should not have been permitted to discuss, that subject in his argument to the jury. It may be true that Mrs. Parrish did not voluntarily become Brinton’s creditor, and that the debt was wrongfully created by him without her knowledge and consent, but in accepting the note, she forgave the offense and treated the indebtedness as an *76ordinary loan. ■ If plaintiffs were denying the indebtedness, the proof offered by appellant would have been competent and relevant, but with the issues as presented by the demand, the proof was clearly irrelevant and could have been offered for no other purpose than that of inflaming the minds of the jury against the plaintiffs.
The learned trial judge erred in modifying the judgment. There is no merit in the argument of appellant that in allowing her husband’s note to be credited on the joint demand of plaintiffs, Mrs. Brinton assumed the payment of the note. Should another trial result in a verdict for the estate, no judgment should be rendered against Mrs. Brinton except one for costs.
The judgment is affirmed.
All concur.
