What is a Heggstad Petition

Harvey just received devastating news. His father’s Will, meticulously drafted years ago, was deemed invalid – not due to its contents, but because of a procedural error during signing. A crucial witness was discovered to have been a beneficiary, triggering a presumption of undue influence. Now, Harvey faces the prospect of his father’s estate being distributed according to intestate succession, bypassing his father’s clear wishes and potentially costing the estate tens of thousands in legal fees and lost benefits. This situation, unfortunately, isn’t uncommon, and is where a Heggstad Petition comes into play.

A Heggstad Petition, named after the seminal California case Estate of Heggstad (1981) 29 Cal.3d 351, is a petition filed with the probate court seeking approval of a Will that is not self-proving and has issues with the witnessing or execution. It’s essentially a request for the court to validate a potentially flawed Will, often when a procedural error exists that could otherwise lead to its invalidation. This isn’t about challenging the terms of the Will itself; it’s about fixing a technical defect in how it was signed or witnessed.

When is a Heggstad Petition Necessary?

Typically, a Will accompanied by a valid self-proving affidavit (pursuant to Probate Code § 8220) streamlines the probate process. The affidavit contains sworn statements from the testator (the person making the Will) and the witnesses, attesting to the proper execution. If a self-proving affidavit exists, the court generally accepts the Will as valid without needing testimony from the witnesses. However, if the affidavit is missing, or is itself flawed, a Heggstad Petition becomes crucial. Common scenarios include:

• Missing Witness: A witness is unavailable or refuses to testify, and their signature isn’t self-proved.
• Improper Witness: As in Harvey’s case, a witness was an “interested witness” (a beneficiary) as defined in California Probate Code § 6112, creating a presumption of undue influence.
• Technical Defects: There were errors in the execution, such as incorrect dates or signatures not appearing in the correct order.
• Lost or Destroyed Affidavit: The original self-proving affidavit is lost or destroyed.

What Does the Court Consider?

The court’s analysis in a Heggstad Petition isn’t a full-blown Will contest. Instead, the court focuses on whether the testator intended to sign a valid Will. The petitioner must demonstrate, through credible evidence, that the testator possessed testamentary capacity (understood they were making a Will and its effects), and that the Will represents their true wishes. Evidence might include:

• Testimony from the Attorney: The attorney who drafted the Will can testify about the testator’s mental state and intent.
• Statements from Family and Friends: Individuals who knew the testator can provide evidence regarding their mental capacity and testamentary intent.
• Copies of Earlier Drafts: Earlier drafts of the Will can demonstrate the testator’s consistent wishes.
• Circumstantial Evidence: Any other evidence that supports the testator’s intent.

What Happens if the Petition is Denied?

If the court denies the Heggstad Petition, the Will is considered invalid. This means the estate will be distributed according to California’s intestate succession laws – as if the testator died without a Will. If a Will is invalidated, assets fall under intestacy; however, for deaths on or after April 1, 2025, estates with personal property under $208,850 (per CPC § 13100) may still bypass full probate via affidavit. This can have significant consequences, potentially leading to unintended beneficiaries receiving assets, and increased administrative burdens and costs.

Can a Heggstad Petition Fix Any Defect?

No. The court’s power to validate a defective Will is not unlimited. Probate Code § 6110(c)(2) states that the court may validate a signature-defective Will if there is “clear and convincing evidence” of the testator’s intent; however, this requires a costly court petition and is not a guaranteed safety net. Fundamental flaws, such as a forgery or a complete lack of testamentary capacity, cannot be cured by a Heggstad Petition. The error must be something that doesn’t inherently negate the testator’s intent, but creates a procedural challenge to accepting the Will.

The CPA Advantage in Heggstad Cases

As an Estate Planning Attorney and CPA with over 35 years of experience, I often find that the most significant complications in these cases arise from tax implications. A successfully validated Will can preserve crucial tax benefits, such as the step-up in basis for inherited assets. If the Will is invalidated and assets are distributed through intestacy, those benefits can be lost, resulting in significant capital gains taxes for the heirs. Proper valuation of assets is also critical, and a CPA’s expertise can be invaluable in ensuring compliance with tax laws.

Having a properly executed Will, and ensuring a valid self-proving affidavit, is paramount. However, even with the best planning, unforeseen circumstances can arise. A Heggstad Petition can be a vital tool to protect your client’s wishes and prevent unintended consequences.

How do California courts decide whether a will reflects true intent or creates ambiguity?

In California, a last will and testament operates within a probate system that emphasizes intent, clarity, and procedural compliance. When properly drafted, a will does more than distribute property—it creates legally enforceable instructions that guide courts, fiduciaries, and beneficiaries through administration with fewer disputes and less uncertainty.

When a will is drafted with California probate review in mind, it becomes a stabilizing roadmap rather than a source of conflict. Clear intent, proper authority, and compliant execution protect both families and estates.
