Cundick v. Broadbent

383 F.2d 157 (1967)

Quick Summary

Darwin Cundick (plaintiff) sold his sheep ranch to J.R. Broadbent (defendant), but his wife sought to rescind the contract claiming her husband was mentally unfit at the time of agreement. The dispute centered around Mr. Cundick’s mental capacity and whether Mr. Broadbent had acted fraudulently or taken advantage of Mr. Cundick’s condition.

The trial court found Mr. Cundick competent and dismissed the case, which was affirmed on appeal despite evidence of potential undervaluation of property sold and Mr. Cundick’s prior mental health treatments.

Facts of the Case

Darwin Cundick (plaintiff) agreed to sell his sheep ranch to J.R. Broadbent (defendant) in September 1963. The contract was reviewed and revised by the plaintiff’s attorney, and then signed by both parties.

In October, the agreement was further amended to increase the purchase price. By March 1964, Broadbent had paid the purchase price and was close to completing the sale. However, Cundick’s wife, as guardian ad litem, filed an action to rescind the contract due to her husband’s alleged mental incapacity.

Evidence presented showed that the ranch was worth double the sale price and that Cundick had a history of mental illness. Despite this, the trial court found Cundick competent to handle his affairs and that the contract was not unconscionable, dismissing Mrs. Cundick’s action.

Whether Darwin Cundick was mentally competent to enter into a contract for the sale of his sheep ranch and whether J.R. Broadbent acted fraudulently or took advantage of Cundick’s mental state.

Rule of Law

The modern rule considers contracts made by a person claiming mental deficiency, but not under guardianship, to be voidable at the instance of the deficient party if there is absence of fraud or knowledge of incapacity by the other contracting party.

Reasoning and Analysis

The appellate court reviewed evidence including expert medical testimony that suggested Cundick was mentally incapable of managing his affairs at the time of the transaction.

However, there was also evidence indicating that Cundick acted competently during the transaction period. This included him participating in activities related to the sale and dealing with legal documents.

The court also considered that Cundick’s mental condition was not known in his community or by Broadbent, which influenced its finding of competency.

Regarding fraud or overreaching, while there was evidence that the property sold for less than its value, there was no proof that Broadbent knew of Cundick’s mental state or that he intentionally took advantage of it. Additionally, adjustments were made to the contract price upon complaint, which contradicted claims of fraud.


The appellate court affirmed the trial court’s judgment, dismissing the action brought by Mrs. Cundick.

Dissenting Opinions

Judge Hill dissented, expressing a firm conviction that a mistake had been made by the trial judge and that a miscarriage of justice had occurred. He emphasized the strength of the medical testimony regarding Cundick’s mental incompetence and considered the evidence relied upon by Broadbent as trivial in contrast.

Key Takeaways

  1. The court differentiated between totally incompetent individuals whose contracts are void ab initio and those with partial mental infirmity whose contracts are voidable.
  2. Contracts made by persons with mental deficiencies are voidable at their instance unless there is fraud or knowledge of incapacity by the other party.
  3. In assessing mental competency for contract purposes, courts will look at a person’s ability to understand the nature and effect of their actions rather than just medical diagnoses or opinions.

Relevant FAQs of this case

What safeguards exist to protect parties with mental incapacity in contract law?

Contract law protects parties with mental incapacity by classifying their agreements as voidable. This means that the contract can be affirmed or rejected by their legal representatives or by the parties themselves if they regain capacity.

  • For example: A person with temporary memory loss signs a contract to purchase a car. Once they fully recover, they can choose to affirm the contract or declare it void.

How might a contract be affected if one party unknowingly engages with someone who has a mental deficiency?

If a contracting party unknowingly enters into an agreement with someone who has a mental deficiency, the contract is typically considered voidable at the instance of the party with the deficiency. However, it may be upheld if the mentally deficient party (or their guardian) does not choose to rescind it and if there’s no exploitation involved.

  • For example: An individual sells artwork to a buyer without knowing the seller has Alzheimer’s. The contract can be voided if the seller or their guardian elects to do so upon discovering the condition.

What is required for a court to determine that a contract made by an individual with a mental impairment is valid?

A court will validate a contract made by an individual with a mental impairment if there was an absence of fraud, coercion, or exploitation by the other party and evidence that, at the time of the agreement, the individual understood the nature and consequences of their actions.

  • For example: Even if someone has been diagnosed with bipolar disorder, if they demonstrate clear intention and understanding when entering a lease agreement during a period of stability, that contract would likely be deemed valid.
