Oklahoma Estate Litigation: Common Reasons to Dispute a Will

Losing a loved one is never easy—and when questions or concerns arise about how their estate is being handled, it can add legal and emotional strain to an already difficult time. Estate litigation refers to the legal process of disputing a will or the administration of an estate. While most wills go through probate without issue, there are situations where families feel the need to challenge a document or decision to protect their loved one’s true intentions.


If you're wondering whether you have legal grounds to dispute a will or trust, understanding the common reasons for estate litigation in Oklahoma is a good place to start.


Common Reasons to Contest a Will

While every case is different, here are a few of the most common legal reasons families pursue estate litigation:


1. Lack of Mental Capacity

If the person who created the will (the testator) was not of sound mind when it was signed, the will may not be legally valid. This is often the case when dementia, cognitive decline, or serious illness affects a person’s ability to understand what they’re signing.


2. Undue Influence

Sometimes a caregiver, relative, or outside party exerts pressure on the testator to change their will. If the court believes the will was signed due to manipulation or coercion, it may be invalidated.


3. Fraud or Forgery

If someone tricked your loved one into signing a document or altered a will without proper authorization, you may have grounds to pursue legal action.


4. Improper Execution

Each state has laws about how a will must be signed and witnessed. If those formalities weren’t followed, the will may not hold up in court.


5. Disputes Over Asset Distribution or Trust Management

Even when the will itself is valid, disagreements can arise about how assets are divided, how the estate is being managed, or whether a trustee or executor is acting in good faith.


Taking the Next Step

If you believe your loved one’s true wishes were not reflected in their will or trust, or if you suspect wrongdoing, you don’t have to navigate the legal process alone. Estate litigation is complex, but it exists to help ensure fairness and protect the rights of beneficiaries and family members.
