— The plaintiff brought suit against the defendant for a balance claimed to be due on a.running account. The defendant answered by way of general denial, and set up a counter-claim for $2,026.73. On the trial of the cause before a jury, such proceedings were had that the defendant recovered judgment on the plaintiff's cause of action, as well as on her counter-claim. The plaintiff appeals from the judgment on the counter-claim only, and assigns for error that the court should have declared the contract, on which such counter-claim was founded, illegal and contrary to public policy, and that the court also erred in admitting oral evidence in support of a subsequent consideration of the alleged contract.
It appeared in evidence that the defendant’s husband died intestate in the year 1888, leaving a very large estate, on which the statutory commissions of an administrator would amount to $35,000 or more. The defendant thereupon executed the following paper:
*6“St. Louis, December 10, 1888.
“I, the undersigned, widow of Charles H. Nash, late of the city of St. Louis, deceased, do hereby relinquish all right, claim or preference I may have to administer the estate of said deceased, and hereby request that letters of administration on said estate may be granted to Robert O. Greer of said city.
“The children of said deceased, and the only remaining distributees of his estate are minors.
“Isabella Nasi-i.
“Robert C. G-reer.”
Upon this paper being filed in the probate court, letters of admininistration were granted on the estate to the plaintiff. There is no substantial evidence in the record that this relinquishment of right on part of the defendant to administer on her husband’s estate was brought about by any promises on part of the plaintiff. About one month thereafter the plaintiff and defendant met, and, upon the suggestion of a mutual friend, it was agreed that the plaintiff should pay to defendant one half of the commissions which he would receive as administrator. An instrument in writing to the effect was drawn up and signed and sealed by the parties. This instrument recited, “that the said Greer for a good and valuable consideration to him paid from Isabella Nash, full payment and satisfaction of which consideration has heretofore been made,” sold and assigned to her one half of the commissions which he was to receive as administrator, “after first deducting from the gross commissions allowed him the sum or sums paid to said American Security Company for its said suretyship.”- A prior clause of the agreement recited that the American Surety (sic) Company, of New York, was one of the sureties on the plaintiff’s bond as administrator, and charged him certain amounts for the risk.
*7There was evidence tending to show that at this meeting it was agreed between the parties that, in consideration of the plaintiff’s paying to the defendant one half of the commissions, the defendant should pay one half the amount charged by the security company for its suretyship. There is no controversy touching the fact that, shortly after this meeting, the plaintiff, who had charge of the defendant’s individual property, likewise charged against her account on his books the sum of $2,000, being one half of the amount charged by the security company to the plaintiff for the first year of its risk.
When the testimony touching this oral agreement as to each party paying one half of the costs of the suretyship was offered, the plaintiff objected thereto as contradictory of the written agreement. The court overruled the objection, and this ruling is one of the errors complained of.
This assignment is based on a misconception of the law. The instrument sued on, being a written promise to pay money, imports a consideration under our Revised Statutes, 1889, section 2389. Being an instrument under seal, it imports 'a consideration at common law. Of course it was competent for the plaintiff to prove that the consideration was either illegal or insufficient, but on what principle the defendant is precluded from showing by extrinsic evidence that there was a valuable consideration for the promise is not apparent, since' consideration or its want may always be shown by extrinsic evidence in a controversy between the original parties to the contract, even-though the evidence tends to' vary the consideration stated in the instrument. 1 Greenleaf on Evidence, sec. 304; 1 Parsons on Contracts, 290; 3 Washburn on Real Property, 399; Sexton v. Anderson, 95 Mo. 373. This assignment of error, therefore, must be overruled.
*8Proceeding to the consideration of the main proposition in this case, we readily concede to the plaintiff that, while the office of an administrator in this state is not a public office, yet trafficking in this office is equally contrary -to the policy of the law and is impliedly prohibited. It has been decided in Porter v. Jones, 52 Mo. 399, 403, that contracts based upon such a traffic are unenforceable. But, as we have stated above, no substantial evidence was given that the defendant recommended the plaintiff as administrator on faith of his promise subsequently made that he would divide his commissions with her, or that she even anticipated that he would make such a promise in the future. The plaintiff had been appointed, had qualified and was acting as administrator for some time, when the promise was made. That the defendant paid half of the cost of his sureties is not even seriously controverted. With the adequacy of this consideration we have nothing to do. It is one which the law regards as valuable and which is sufficient to support the contract, although, as above seen, the instrument itself made a prima facie case for the defendant.
It appeared in' evidence that the plaintiff did pay to the defendant one half of the commissions which he earned as administrator during the first year. His refusal to do so, during the second year appears to have ' ■no other foundation than that she resisted a claim of his for a balance on account, which, as the jury found, was without foundation.
There is no merit in the appeal, and, all the judges concurring, the judgment is affirmed.
