## Facts

- Stephanie B. Kendrick sued Daniel L. Barker, d/b/a Barker Construction, seeking damages for injuries from a prior collision between her vehicle and Barker’s tractor-trailer.
- The case was set for trial, and the district court ordered the parties to attend a pretrial settlement conference with a mediator.
- Following the June 4, 1999 settlement conference, the mediator sent a June 7, 1999 letter setting out a tentative settlement: Barker would pay $40,000 “in full settlement of all claims,” with an acceptance deadline of June 8.
- On June 8, 1999, Kendrick’s attorney sent a written acceptance by fax accepting “$40,000.00 in full settlement of all claims against the Defendant,” and the court was notified that the case had settled; the trial setting was vacated.
- After draft settlement papers were circulated, Kendrick told her attorney she did not accept the settlement, retained new counsel, and opposed enforcement.
- Kendrick later was diagnosed (July 19, 1999) with a closed head injury and argued she did not know whether the settlement would cover future medical expenses.
- Kendrick asserted defenses to enforcement including mutual mistake (based on the later diagnosis), unconscionability, duress, and that her acceptance was contingent on receiving a later written agreement acceptable to her (including objections about allocation of proceeds and possible insurer reimbursement).
- Barker moved to enforce the settlement agreement. After a hearing at which Kendrick acknowledged she understood the $40,000 was meant to settle her claims and she had not expressly reserved any claim, the district court enforced the settlement and entered judgment for Barker.

## Issues

1. Whether the parties formed an enforceable settlement agreement to resolve all claims for $40,000 when the mediator’s written summary was accepted by Kendrick’s counsel and the court was notified the case had settled.
2. Whether Kendrick could avoid enforcement based on mutual mistake because she was later diagnosed with a closed head injury not identified at the time of settlement.
3. Whether Kendrick’s acceptance was contingent on execution of later written settlement documents in a form acceptable to her.
4. Whether duress or unconscionability prevented enforcement of the settlement.

## Decision

- The Wyoming Supreme Court affirmed the judgment enforcing the settlement.
- The court held the record supported the district court’s finding that a complete settlement existed: $40,000 in exchange for a release of all claims, with no agreed contingencies.
- The court rejected Kendrick’s contention that later paperwork was a condition to contract formation; subsequent documents were to record the already-made agreement.
- The court held Kendrick could not set aside a general settlement and release on the theory of mutual mistake merely because a later medical diagnosis revealed a more serious or additional injury; by settling without reserving claims, she accepted the risk that her condition might change or prove worse than expected.
- The court agreed that Kendrick failed to establish duress or unconscionability sufficient to defeat enforcement.
- The court confirmed that trial courts may enforce settlement agreements in pending cases through summary enforcement procedures; enforcement authority does not depend on the summary-judgment rule.

## Legal Principles

- Settlement agreements are contracts; courts look to objective manifestations of assent and enforce settlements when the material terms are agreed and accepted.
- A trial court may summarily enforce a settlement reached in a case before it when the agreement is shown by the record and the parties’ actions (including notifying the court and vacating trial settings).
- A settlement to release “all claims” in a personal-injury case generally places the risk of later-discovered or more serious injuries on the releasor when the claimant settles with awareness that the full extent of injury may be uncertain and does not reserve specific claims.
- Mutual mistake is not established merely by a later medical diagnosis; the fact that an injury proves worse than believed does not, by itself, justify rescinding a general release.
- Duress requires wrongful pressure that overcomes a party’s free will; dissatisfaction with the bargain after the fact, without wrongful coercion, is not enough.
- Unconscionability requires a strong showing of unfairness in the bargaining process or terms; a mediated, counseled settlement with clear terms is unlikely to meet that standard.

## Conclusion

Kendrick v. Barker held that the parties’ $40,000 settlement to resolve all claims was enforceable after Kendrick’s counsel accepted the mediator’s written settlement terms and the court vacated trial, and Kendrick could not avoid the agreement based on a later diagnosis of a closed head injury or by asserting that later written paperwork, duress, or unconscionability defeated the settlement.
