Opinion by
The appellants, Peter Quarture and Pearena Quarture, his wife, in September, 1936, were the owners of real estate, by the entireties, located in South Fayette Township.
State Highway Route 545 had been widened and relocated on this property of the appellants, causing considerable damage.
Peter Quarture retained Mayer Sniderman, Esq., on September 24, 1936, to represent him and his wife, Pearena Quarture, in their claim against Allegheny County. On that day, Mayer Sniderman prepared a power of attorney naming himself as their lawful attorney to represent them in their cause of action against the county. The power of attorney contained provisions that Mayer Sniderman would prosecute to final determination, if necessary, any action or suit for the sum of ten per cent of all that might be recovered; expenses of $150 to be deducted from the gross award.
The claim was heard before the Board of Viewers and the sum of $1,650 was awarded. Thinking this was inadequate, Peter Quarture took an appeal through his attorney, Mayer Sniderman, to the court of common pleas. The case went to trial and the jury returned a verdict of $2,961 on December 8¿ 1938. There is conflicting testimony as to what fee Mayer Sniderman was to receive for the jury trial. Peter Quarture relied on the written agreement, while Mayer Sniderman set up an oral contract which gave him 33-1/3% of the verdict. In June of 1939, Mayer Sniderman presented a petition to the court praying that the verdict be paid into court and distribution made and that the fund of $2,961 be charged with a lien to the extent of $987 for the services of Mayer Sniderman. An answer was filed *359 by Peter Quarture to this petition and tbe case was beard before Smith, J., on transcribed testimony taken on February 23, 1939. An order of distribution was made on July 12, 1939, as amended July 17, 1939, in wbicb tbe protbonotary, in tbe name of tbe court, was ordered to distribute tbe fund, of wbicb $987 was to be given to Mayer Sniderman. Peter Quarture filed exceptions to tliis order and before Marshall, Smith, Kennedy, JJ., tbe exceptions were severally dismissed, Kennedy, J., dissenting. This appeal followed.
Tbe power of attorney, copy of wbicb appears in tbe record as Exhibit “A” attached to tbe answer, is apparently signed only by Mayer Sniderman. Appellee admits in bis brief that tbe instrument was signed also by Quarture.
We cannot agree with tbe contention of appellee that tbe power of attorney is a purely unilateral legal instrument or that tbe client alone is obligated by its terms, or that it does not in fact bind or obligate tbe attorney to do anything. It is clearly a bilateral agreement under wbicb tbe attorney agrees to perform certain services, and for these services be is to receive a certain percentage of tbe amount which may be recovered.
Tbe function of tbe lower court, as well as of this court, is to ascertain tbe intention of tbe parties from tbe language of tbe contract wbicb is unambiguous in character.
Under tbe terms of tbe power of attorney, Snider-man is constituted as attorney to “institute, conduct, superintend or prosecute to final determination, if necessary, a suit or suits, action or claim against tbe County of Allegheny on account of taking, injuring, and affecting (my, our) property in tbe relocation, widening, and opening of tbe State Highway, known as Route No. 545.” (Italics supplied).
Pursuant to tbe power of attorney, tbe attorney prose *360 cuted the claim of Quarture before the Board of Viewers of Allegheny County and received an award of $1,650. After the receiving of this award, the testimony shows that the attorney and client met and discussed the prosecution of an appeal and that the attorney viewed the successful prosecution of an appeal as uncertain and took the position that he would accept the award of the Board of Viewers and not take an appeal to the common pleas court unless the power of attorney aforesaid was cancelled and a new agreement was made between him and the client whereby he, as attorney, would receive, as his fee, a percentage of any recovery that might be made on the appeal, larger than the 10% provided for in the power of attorney.
The depositions taken on behalf of Mayer Sniderman, show that there was considerable discussion between the attorney and client with regard to this subject and that the final result thereof was that the power of attorney was cancelled or withdrawn by mutual agreement of the parties and that, before the taking of any appeal, a new agreement was made between the attorney and client whereby the attorney was to receive as his fees for the prosecution of the appeal, 33-1/3% of whatever recovery might be had.
After the making of this agreement, the attorney took and prosecuted an appeal to the court of common pleas and succeeded in securing a verdict of $2,961 in favor of the client.
When the question of the distribution of this verdict arose, the client insisted that the attorney was only entitled to 10% thereof, the percentage provided for in the original power of attorney. The attorney, on the other hand, claimed 33-1/3% of the verdict under the terms of the verbal agreement between him and the client made, as aforesaid, after the award of the Board of Viewers and before the taking of the appeal.
The court below held that the client was bound by the terms of the new verbal agreement which he made with *361 the attorney, as aforesaid, and awarded the attorney, out of the verdict, a fee computed on the 33-1/3% basis.
Appellee contends that the parol evidence rule is not involved in this case, and that as stated in
KoEune v. State Bank of Schuylkill Haven et al.,
While we agree with this statement, nevertheless where a subsequent oral contract is depended on, to change the terms of a prior written contract, it must be clearly and positively shown. We quote from the opinion of Judge Parker of our court in
Goldman v. National Refrigerator Co., Inc.,
*362 Appellee’s contention is that the instant case was one of cancellation and rescission of the original power of attorney by mutual assent of both parties, and the substitution for that power of attorney of an entirely new and separate verbal agreement of the parties.
Our first duty is to construe the original power of attorney. What is meant by the terms “final determination?” Bouvier’s Law Dictionary, 1934 Volume at p. 414 refers “final determination” to “final disposition”, and under the latter, the following definition is given: “Final disposition.—Such a conclusive determination of the subject-matter embraced in a submission to arbitrators, that after the award is made nothing further remains to fix the rights and obligations of the parties, and no further controversy or litigation can arise thereon.” In
Dean et al. v. Marshall et al.,
The proceedings before the Board of Viewers cannot be considered as a “final determination” as their award is subject to appeal by either the owner of the property or by the municipality. If it were intended to provide for additional compensation in case of appeal from the aAvard of viewers, it would have been a simple matter to have so provided in the power of attorney. We cannot rewrite the contract, we must construe it as the parties have written it.
In relation to the alleged change in the contractual relations between Mayer Sniderman and Peter Quarture, *363 the testimony of Mayer Sniderman was substantially that after the hearing before the Board of Viewers and before an appeal was taken, Peter Quarture came into his office and orally agreed to pay him 33-1/3% of the verdict on appeal and that Quarture again promised the same thing before witnesses outside of the assignment room of the common pleas court just before the trial of the case. The other persons testifying were real estate expert witnesses who claimed they were present and heard Quarture promise Sniderman he would pay him 33-1/3%, outside of the assignment room before the trial of the case.
The only difference between the power of attorney and the alleged oral contract is the amount of the compensation to be paid to Sniderman. The services to be rendered by the latter were the same in every respect.
Appellant denies having ever made the alleged oral agreement to pay additional compensation and contends that the alleged promise, if made, is void for lack of consideration.
The general principle is stated in 13 C. J. 351, as follows: “A promise to do what the promisor is already bound to do cannot be a consideration, for if a person gets nothing in return for his promise but that to which he is already legally entitled, the consideration is unreal.” Likewise, at p. 353: “The promise of a person to carry out a subsisting contract with the promisee or the performance of such contractual duty is clearly no consideration, as he is doing no more than he was already obliged to do, and hence has sustained no detriment, nor has the other party to the contract obtained any benefit. Thus a promise to pay additional compensation for the performance by the promisee of a contract which the promisee is already under obligation to the promisor to perform is without consideration.” See also, Restatement of Law of Contracts, §76a.
There are many cases in which this rule of law is
*364
laid down or adhered to but one that clearly sets out the reason for the rule is
Lingenfelder v. Wainwright Brewing Co.,
In
Erny v. Sauer,
While we do not question the value of the servicés rendered by Mr. Sniderman, we are nevertheless constrained by reason of our interpretation of the written agreement, to limit the right of recovery to the amount stipulated therein. It is unfortunate that the written agreement did not stipulate additional compensation in case of an appeal.
The order and decree of the court below is reversed and the record is remitted for further proceedings, not inconsistent with this opinion. Costs to be paid by appellee.
