How Much Does a Heggstad Petition Cost

I recently spoke with Emily, a woman devastated by a simple oversight. Her mother, a meticulous planner, had carefully drafted a Will years ago. Unfortunately, after her mother’s passing, Emily discovered the Will was missing a crucial signature page. Despite the obvious intent, California law requires strict compliance with the execution requirements outlined in Probate Code § 6110. Emily faced a costly and stressful court battle – a Heggstad Petition – to validate the defective Will. She’d assumed a minor technicality wouldn’t matter, a mistake that ended up costing her thousands in legal fees and emotional distress.

As an Estate Planning Attorney and CPA with over 35 years of experience here in Corona, California, I see these situations frequently. The cost of a Heggstad Petition is unfortunately difficult to pinpoint precisely, as it depends heavily on the complexity of your case, the assets involved, and potential challenges from other interested parties. However, I can give you a realistic overview to help you prepare.

What Factors Drive the Cost of a Heggstad Petition?

The primary driver of cost is attorney’s time. Preparing and filing a Heggstad Petition is not a simple task. It requires a thorough review of the Will itself, gathering evidence to demonstrate the testator’s (the person who made the Will) intent, preparing legal declarations, and potentially taking depositions of witnesses. Here’s a breakdown of typical cost components:

• Attorney’s Fees: These are often billed hourly, ranging from $450 to $800+ per hour, depending on the attorney’s experience and location. A relatively straightforward case might require 20-40 hours of work, while a contested case could easily exceed 80 hours.
• Court Filing Fees: California court fees are subject to change, but currently, filing a Petition to Validate a Will starts around $600.
• Witness Fees: If you need to subpoena witnesses to testify about the testator’s intent or the circumstances of the Will’s execution, you’ll need to pay their mileage and a nominal appearance fee.
• Investigator Fees: In some cases, it may be necessary to hire a private investigator to locate witnesses or gather evidence.
• Expert Fees: Depending on the complexity of the case, you might need to engage a forensic document examiner or handwriting analyst, adding to the overall expense.

Can the Court Validate a Defective Will?

The good news is that the court has the power to validate a Will, even if it contains technical errors, under Probate Code § 6110(c)(2). However, this is not automatic. You must present “clear and convincing evidence” that the testator intended the document to be their Will. This often requires demonstrating the document was signed with testamentary intent, even if the signature doesn’t perfectly adhere to the legal requirements. The process also requires proper notice to all interested parties, giving them an opportunity to object.

What if a Beneficiary Witnessed the Will?

This is a particularly sensitive situation. Under California Probate Code § 6112, if a beneficiary (someone who stands to inherit from the Will) also acted as a witness, it creates a legal presumption of undue influence or fraud. Unless you can present two other disinterested witnesses, the beneficiary may lose their gift under the Will. This significantly complicates the Heggstad Petition and increases the associated costs due to the need for more robust evidence and potentially expert testimony.

How Does a CPA Help in These Situations?

As a CPA as well as an attorney, I bring a unique perspective to estate planning and probate matters. Properly valuing assets is critical, and the potential for a step-up in basis can save your estate significant capital gains taxes. Moreover, I can help ensure that your Will is drafted in a way that minimizes potential tax liabilities and maximizes the value of your estate. A seemingly small oversight in Will execution can have massive financial consequences, and my expertise in both tax law and estate planning can help you avoid these pitfalls.

What if the Estate is Small?

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 is a much simpler and less expensive process, but it’s only available if the estate meets the criteria.

While California allowed temporary remote witnessing during the pandemic, the law (CPC § 6110) has reverted to requiring strict simultaneous presence; remote signatures are generally invalid for Wills unless they meet the narrow ‘Electronic Will’ standards of AB 298. This underscores the importance of proper execution with all witnesses present at the same time.

What makes a California will legally enforceable when it matters most?

In California, a last will and testament is reviewed under probate standards that focus on intent, capacity, and execution. Clear drafting reduces ambiguity, limits misinterpretation, and helps families avoid unnecessary conflict during estate administration.

For California residents, understanding how intent, authority, and compliance interact is one of the most effective ways to protect family harmony and estate integrity. A will that anticipates probate scrutiny is far more likely to be honored as written and far less likely to become the source of unnecessary conflict.
