Proving Undue Influence in Missouri Estate Litigation: Caregivers, Spouses, and Siblings

Discovering that a parent's lifetime of savings has been redirected to a new caregiver, a recently acquired spouse, or an estranged sibling can be devastating. In Missouri, adults have the right to leave their money to anyone they choose. However, if that choice was the result of manipulation, coercion, or deceit, the law provides a remedy. Filing a lawsuit for 'undue influence' allows families to invalidate tainted wills and trusts and restore the true wishes of their loved one.

Understanding Undue Influence in Missouri

Undue influence goes beyond simple persuasion or nagging. Under Missouri law, undue influence means that a person exerted such extreme pressure or manipulation that the deceased's own free will was destroyed, replacing it with the desires of the manipulator. Proving this requires showing that the manipulator actively procured the change in the estate plan. Because this manipulation almost always happens behind closed doors, courts rely on circumstantial evidence.

In-Home Nurses and Caregivers

Elderly individuals often become physically dependent on in-home nurses or daily caregivers. Unfortunately, some bad actors use this dependency to isolate the senior from their family. They may intercept phone calls, manage the senior's checkbook, and eventually drive them to an attorney to draft a new will. If a caregiver ends up as the primary beneficiary, courts at the Greene County Circuit Court, Probate Division, Springfield will heavily scrutinize the relationship.

Aggressive New Spouses (Late-in-Life Marriages)

Late-in-life marriages often lead to complicated estate battles. A predatory new spouse might threaten to withhold care or use emotional abuse to force the deceased to disinherit their adult children. If the new spouse isolated the deceased and arranged for a completely new estate plan shortly before their death, beneficiaries have strong grounds to pursue an undue influence claim.

Estranged Siblings Taking Control

Sometimes the manipulator is a family member. It is common for an estranged sibling to suddenly move back in with an ailing parent under the guise of 'helping.' If that sibling secretly arranges for a new deed or trust that leaves everything to them, excluding the rest of the family, this is a classic indicator of undue influence.

The 'Confidential Relationship' and Shifting the Burden of Proof

Normally, under Mo. Rev. Stat. § 473.083, the person contesting the will has the burden to prove it is invalid. However, Missouri has a powerful legal tool called the 'presumption of undue influence.' A key precedent, Watermann v. Eleanor E. Fitzpatrick Revocable Living Trust, 369 S.W.3d 69 (MO Court of Appeals 2012), outlines how this works.

To trigger this presumption, you must prove three things: (1) a confidential or fiduciary relationship existed (the manipulator handled their finances or had deep trust), (2) the manipulator was active in procuring or drafting the new will, and (3) the manipulator benefited from the new will. Once you prove these three elements, the burden of proof completely shifts to the accused. They must now prove to the judge that they did not unduly influence the deceased.

Step-by-Step Guide to Filing a Claim

• Step 1: Secure an Attorney. Undue influence cases are incredibly complex. You must hire an estate litigator from our directory immediately.
• Step 2: File the Legal Petition. Your lawyer will draft a formal lawsuit, filing an independent Petition to Contest Will on Grounds of Undue Influence pursuant to Mo. Rev. Stat. § 473.083, and file it in the appropriate court, like the St. Charles County Circuit Court, Probate Division, St. Charles.
• Step 3: Issue Subpoenas. Your attorney will request bank records, phone logs, and the drafting attorney's file to prove the manipulator arranged the changes.
• Step 4: Take Depositions. The accused manipulator will be forced to answer questions under oath about their involvement in the estate planning process.

How Much Does Estate Litigation Cost?

Litigating an undue influence case is a significant financial investment. Because these cases require extensive discovery and depositions to uncover hidden manipulation, attorneys usually charge hourly rates of $250 to $450. You should expect an initial retainer of $7,500 to $15,000. If the case proceeds all the way to a jury trial, total legal fees can exceed $30,000 to $50,000. In some rare cases where the evidence is overwhelming, an attorney might agree to a contingency fee arrangement.

How Long Does the Lawsuit Take?

Uncovering financial manipulation takes time. Most undue influence cases in Missouri take between 12 and 24 months to resolve. If the parties agree to a mediation settlement, it might be resolved in under a year, but a full trial will take significantly longer due to court backlogs.
