When families disagree about the care and finances of an aging loved one, emotions can run high—and legal missteps can have lasting consequences. A recent Missouri Court of Appeals decision highlights how strictly courts enforce procedural rules in guardianship and conservatorship cases, and why timing and consistency matter when challenging probate court rulings.

Background: Dispute Over Care, Capacity, and Control

In Lee v. Clark, a son petitioned the probate court to appoint a guardian and conservator for his elderly mother, citing Alzheimer's disease, cognitive decline, and an inability to manage daily needs or finances. After medical evaluations, court-appointed counsel, and a hearing, the probate court found the mother incapacitated and disabled under Missouri law and appointed the county public administrator as guardian and conservator.

Several years later, after the conservator filed a final settlement and sought discharge, the son attempted to challenge not only the final accounting but also the original 2019 guardianship and conservatorship judgment, arguing due process violations and lack of proper notice.

The probate court rejected those arguments, approved the final settlement, and discharged the conservator. The son appealed.

Key Issue #1: You Must Appeal Guardianship Orders on Time

One of the most important lessons from this case is procedural: appeals in probate cases are strictly time-limited.

The Court of Appeals held that the son could not challenge the 2019 guardianship judgment in a 2024 appeal. Under Missouri law, appeals from probate judgments—especially those determining incapacity—must be filed within the statutory deadline. Because no timely appeal was filed in 2019, that judgment became final.

Courts will not reopen long-final guardianship determinations simply because a party later disagrees with the outcome.

Key Issue #2: You Cannot Take Inconsistent Positions on Appeal

The court also emphasized a principle that surprises many litigants: you cannot ask the court for relief and later attack that same relief on appeal.

Here, the son himself filed the original petition requesting appointment of a guardian and conservator and presented evidence supporting incapacity. Because he received exactly what he requested, he could not later argue that the appointment violated due process or was legally improper.

Missouri courts consistently bar parties from taking positions on appeal that contradict their stance at trial.

Key Issue #3: Standing Matters in Due Process Claims

Another critical takeaway is standing. The son argued that his mother's due process rights were violated during the guardianship proceedings. The Court of Appeals rejected this argument, explaining that constitutional due process rights are personal.

Unless a party's own rights are affected, they generally lack standing to assert constitutional claims on behalf of someone else—even a parent—especially where court-appointed counsel raised no objections at the time.

Final Accounting and Discharge Were Proper

Finally, the court addressed objections to the conservator's final settlement and discharge. The appellate court found that the probate court complied with Missouri statutes governing conservator accountings, notice, and receipts. The final inventory was approved, a successor fiduciary had taken over, and the estate was properly transferred.

As a result, the trial court's approval of the final settlement and discharge of the conservator was affirmed.

Why This Case Matters for Missouri Families

This decision underscores several realities of Missouri probate, guardianship, and conservatorship law:

• Guardianship orders must be challenged promptly

• Parties are bound by the positions they take in court

• Not every family member has standing to raise constitutional claims

• Probate courts are given broad discretion when statutory procedures are followed

If you are considering challenging a guardianship, defending one, or navigating disputes over an aging parent's care or finances, early legal guidance is critical.
