An Overview of Probate and Estate Litigation

Probate litigation grows out of disputes over a person’s assets, their will, or how the estate is being handled after death. Regular probate is a court process that gathers property, pays debts, and distributes what is left. Litigation enters the picture once people disagree on what the documents mean or how the job is being done.

These cases can include will contests, trust disputes, or claims that the executor or trustee acted improperly. Many disputes begin during the normal probate administration process and grow into formal litigation when disagreements cannot be resolved.

Frequent Causes of Probate Litigation

Most disputes cluster around a few repeating themes: questions about the will, fights over a trust, and concerns about how a fiduciary is handling money.

Will Contests: Challenging the Validity of a Will

A will contest asks the court to decide whether a will is valid or not. The challenge targets the document’s authenticity, how it was signed, or what influenced the person who signed it. These disputes often arise during the process of probating a will:

  • Lack of testamentary capacity
  • Undue influence
  • Fraud
  • Duress
  • Mistake
  • Lack of formalities in execution

Courts rely on medical records, witness testimony, and surrounding circumstances to decide these claims.

Trust Disputes: Challenging Trust Terms or Administration

Trust disputes target either the validity of the trust, the meaning of its terms, or how the trustee is managing assets. These issues often lead directly to trust litigation, especially when large assets or unclear language are involved.

Common grounds include:

  • Lack of capacity
  • Undue influence
  • Improper formation
  • Ambiguous or conflicting terms
  • Violations of public policy

Breach of Fiduciary Duty: Misconduct by Executors or Trustees

Fiduciaries must act in the best interests of beneficiaries. When they fail to do so, disputes often escalate into probate litigation.

  • Mismanagement of assets
  • Self-dealing or conflicts of interest
  • Failure to communicate or provide accountings

Courts can step in to correct misconduct and protect the estate.

Heirship Disputes: Determining Legal Heirs

Heirship disputes arise when there is no will or when family members disagree about who should inherit. These cases are common in intestate estates handled through probate.

Courts may need to determine legal relationships based on:

  • Birth or adoption records
  • Paternity findings
  • Evidence of parent-child relationships

These findings directly affect how property is distributed.

Claims Against the Estate: Addressing Creditor Demands

Creditors may file claims against the estate for debts owed. Executors must review and respond to each claim.

Disputes can arise over:

  • Whether the debt is valid
  • Whether the claim was timely
  • How claims are prioritized

These issues often delay distribution and may require court involvement through probate proceedings.

Undue Influence and Elder Financial Abuse

Undue influence frequently involves vulnerable individuals being pressured into changing estate plans. These cases often overlap with trust disputes and probate litigation.

Signs may include:

  • Isolation from family
  • Sudden changes to estate plans
  • Dependence on a single caregiver

Courts can invalidate documents or recover assets if misconduct is proven.

Actions of Trustee or Executor

The conduct of a trustee or executor is often examined closely during disputes. Decisions about investments, distributions, or property sales can all be challenged.

Problems in trust administration or probate management can lead to court action if beneficiaries believe their interests are not being protected.

Remedies and Damages Available in Probate Litigation

If a probate or trust lawsuit succeeds, courts can order both financial and non-financial remedies.

Common outcomes include:

  • Removal of a trustee or executor
  • Repayment of financial losses
  • Court orders to stop harmful actions
  • Correction or invalidation of documents

These remedies are typically pursued through trust litigation or related probate actions.
