Willie Edwards CLINE
v.
Carl C. CLINE and Myrtle Cline Patterson, Executors of Annie S. Cline, deceased.
No. 533.
Supreme Court of North Carolina.
December 12, 1962.
*403 Williams, Willeford & Boger, Concord, for defendant appellants.
Hartsell, Hartsell & Mills by William L. Mills, Jr., Concord, for plaintiff appellee.
RODMAN, Justice.
Defendants assign as error the court's refusal to allow their motion to nonsuit. The evidence was sufficient to permit the jury to find these facts: Plaintiff married Charlie Cline, son of decedent and R. S. Cline, in 1934. R. S. Cline died prior to the marriage. Decedent and Charlie occupied the same home prior to the marriage. It belonged to R. S. Cline at his death. Decedent continued to live in the home with plaintiff and her husband until her death in April 1959. She was then approaching 90, nearly blind, and a diabetic. This condition "started about 1945." She was in need of care and attention for several years prior to her death. Decedent's other children, although living nearby, did little for her. The burden fell on plaintiff. The nature and extent of the services required and rendered increased as decedent grew older. Decedent "didn't expect anybody to do anything for her without being compensated." Decedent stated "she had it in her will" that plaintiff "would be well paid to take care of her." Plaintiff testified: "Mrs. Cline said she had in her will that I'd be paid at her death. She told me that time and time again." Plaintiff testified to her affection for decedent, but when asked the direct question whether she expected compensation for the services rendered, she answered in the affirmative.
Where there is an express contract to pay for services rendered, the parties are bound by the terms of the contract, both with respect to the time of payment and the manner of computing the sum owing.
Where there is no express contract to pay, the law implies a promise to pay fair compensation for services rendered unless rendered as a gratuity or in discharge of some obligation. Allen v. Seay, 248 N.C. 321, 103 S.E.2d 332; Twiford v. Waterfield, 240 N.C. 582, 83 S.E.2d 548; Stewart v. Wyrick, 228 N.C. 429, 45 S.E.2d 764; Grady v. Faison, 224 N.C. 567, 31 S.E.2d 760; Landreth v. Morris, 214 N.C. 619, 200 S.E. 378.
If it be conceded plaintiff has failed to establish an express contract, such failure would not defeat her right to recover the fair value of services rendered under an implied promise to pay. Allen v. Seay, supra; Thormer v. Lexington Mail Order Co., 241 N.C. 249, 85 S.E.2d 140; 58 Am. Jur. 542.
The relationship of mother-in-law and daughter-in-law was not sufficient to raise a presumption that the services were gratuitously rendered and received. Lindley v. Frazier, 231 N.C. 44, 55 S.E.2d 815; Grady v. Faison, supra.
Plaintiff does not seek damages for services rendered more than three years prior to decedent's death. Hence the time when payment became due is not material.
The court properly declined to allow the motion for nonsuit.
Plaintiff's husband filed a claim with defendants for rent asserted to be owing to him by his mother. He included in the statement so filed a claim for plaintiff's services for $4,380. Defendants rejected the claim but offered it in evidence to show the services assertedly rendered by plaintiff were not in fact worth the amount claimed by her. The court sustained plaintiff's objection. Defendants offered no evidence to show plaintiff had authorized her husband to file a claim in her behalf or to fix the amount owing to her. An unauthorized act of a husband cannot impair the property rights of his wife. Her earnings are her separate estate. G.S. § 52-10; *404 Beasley v. McLamb, 247 N.C. 179, 100 S.E.2d 387; Coley v. Dalrymple, 225 N.C. 67, 33 S.E.2d 477.
There is no dispute about the fact that the building occupied by plaintiff, her husband, and decedent was originally owned by plaintiff's father-in-law. His property was partitioned among his heirs about 1934, prior to plaintiff's marriage. Defendants sought to show by two of the commissioners who made the partition that they recommended that decedent be given the right to occupy part of the dwelling as her dower. The court, on plaintiff's objection, excluded the evidence. Its pertinency is not apparent. Plaintiff was making no claim for rent nor was she suggesting that decedent was wrongfully in the home. If pertinent to the inquiry, the court record would be the source to look to in ascertaining the rights of the parties.
Defendants assign as error the charge on the fourth issue. The court charged: "Now the court instructs you as a matter of law on this fourth issue, if you come to it, that if you are satisfied from the evidence and by its greater weight that the plaintiff rendered services to the deceased, Annie S. Cline, and that these services had a reasonable value, then you would answer this issue in whatever amount you are so satisfiedthat is, services during the last three years of her life, and that these services had a reasonable value for the last three years of Annie S. Cline's life, then you would answer this issue in whatever amount you are satisfied by the greater weight of the evidence is the reasonable value of those services, not in excess of ten thousand eight hundred dollars."
Defendants concede that plaintiff, if entitled to recover anything, is entitled to the fair market value of the services performed. They insist that plaintiff on this record is not entitled to recover more than nominal damages because of plaintiff's failure to prove the value of the services rendered. Plaintiff offered no evidence specifically directed to the reasonable cost of providing such services, that is, the market value of such services. She insists that the jury could fix the fair value of the services performed as a matter of common knowledge and without any evidence as to the market value or cost of such services. Plaintiff described in some detail the services she performed. She injected insulin as needed. She washed decedent's clothes and bed linen, helped bathe her, cooked for her, and did such other things as needed to make decedent comfortable and happy. The only evidence which in any way touched on the cost of providing such services was the amount paid a practical nurse who helped plaintiff take care of decedent for the last three or four months of her life.
When a plaintiff seeks to recover compensation for an article sold or services rendered, he must allege and prove its value. As said by Parker, J., in Lieb v. Mayer, 244 N.C. 613, 616, 94 S.E.2d 658, 660: "Damages are never presumed. The burden is always upon the complaining party to establish by evidence such facts as will furnish a basis for their assessment, according to some definite and legal rule." The amount to be paid is not the value of the services to the recipient, Turner v. Marsh Furniture Co., 217 N.C. 695, 9 S.E. 2d 379, nor should his financial condition be taken into consideration in determining the value of the services performed. Sawyer v. Weskett, 201 N.C. 500, 160 S.E. 575. Many factors serve to fix the market value of an article offered for sale. Supply, demand, and quality (which is synonymous with skill when the thing sold is personal services) are prime factors. The jury, when called upon to fix the value, must base its decision on evidence relating to the value of the thing sold. Without some evidence to establish that fact, it cannot answer. To do so would be to speculate. Lieb v. Mayer, supra; Clark v. Emerson, 245 N.C. 387, 95 S.E.2d 880; Berry v. Hyde County Land & Lumber Co., 183 N. C. 384, 111 S.E. 707; Winch v. Warner, 186 App.Div. 710, 174 N.Y.S. 819; Dakoff *405 v. National Bank of Commerce, Tex.Civ. App., 254 S.W.2d 550; Bianco v. Floatex, Inc., 145 Conn. 523, 144 A.2d 310; Wysowatcky v. Lyons, 137 Colo. 578, 328 P.2d 576. The failure of the court to properly instruct the jury with respect to the fourth issue requires a
New trial.
