Contesting a Will in Pennsylvania: Capacity, Undue Influence and Other Issues
A Pennsylvania will is not invalid merely because a beneficiary believes it is unfair. A successful challenge generally requires a legally recognized basis to contest the document or its probate, supported by evidence.
Where is a Pennsylvania will challenged?
Wills are initially presented to the county Register of Wills for probate. Pennsylvania law provides procedures for caveats before probate and appeals from decisions of the Register to the Orphans’ Court division. The correct procedure depends in part on whether the will has already been admitted to probate.
What is a caveat?
Under 20 Pa.C.S. § 906, a caveat can be filed with the Register of Wills concerning the probate of a will or the grant of letters. A caveat can prevent routine probate while the disputed issue is addressed under the statutory procedure.
What is testamentary capacity?
Testamentary capacity concerns whether the person making the will had the legally required mental capacity when the will was executed. Capacity is evaluated under Pennsylvania law and is not necessarily the same question as whether the person had a medical diagnosis, experienced some cognitive decline or needed assistance with other matters.
What is undue influence?
Undue influence is more than persuasion, opportunity or a close relationship. Pennsylvania cases apply specific legal standards and burdens depending on the evidence. Will-contest litigation often examines the testator’s condition, relationships, dependence, the circumstances surrounding preparation and execution of the will, and whether a person in a position of influence received a substantial benefit.
Can improper execution invalidate a will?
A challenge may also involve whether the document satisfies Pennsylvania’s statutory requirements for a will and whether it was properly executed. Questions about signatures, writings, alterations and the authenticity of the instrument require examination of the actual document and surrounding evidence.
What evidence matters in a will contest?
- the original will and prior wills;
- the drafting attorney’s file when discoverable and relevant;
- medical and cognitive records;
- witness testimony about the testator’s condition and relationships;
- financial and caregiving records;
- communications concerning changes to the estate plan; and
- evidence concerning the circumstances of execution.
Why does timing matter?
Probate disputes are procedural as well as substantive. Pennsylvania law provides specific mechanisms and time limits for challenging decisions of the Register of Wills. A potential contestant should therefore investigate promptly rather than waiting until estate assets have been fully administered or distributed.
Frequently Asked Questions About Pennsylvania Will Contests
Can a child contest a will simply because the child received nothing?
No. Disinheritance or an unequal distribution does not itself establish that a will is invalid. The contestant needs a legally cognizable basis for the challenge.
Does dementia automatically invalidate a will?
No. The relevant question is testamentary capacity at the legally relevant time, not merely the existence of a diagnosis. Medical evidence can be important, but it is part of the broader factual analysis.
Can an executor defend the will?
The personal representative and beneficiaries may have roles in litigation concerning the validity or probate of the will. The appropriate positions and use of estate assets for litigation expenses can depend on the circumstances and governing law.
