How Much Does a Heggstad Petition Cost

Harvey just received devastating news. His mother passed away unexpectedly, leaving a handwritten Will. Unfortunately, the Will wasn’t properly witnessed – a single witness, and that witness was also a beneficiary. Now, Harvey faces the prospect of his mother’s estate being distributed according to intestate succession, meaning she hadn’t intended recipients may receive nothing. The family estimates this misstep could cost them upwards of $75,000 in lost inheritance. A Heggstad petition might be their only hope, but Harvey is understandably anxious about the costs involved.

The short answer is: it depends. A Heggstad petition—a request to the court to validate a Will that doesn’t meet standard witnessing requirements—isn’t a fixed-price service. The costs associated with it can vary significantly based on several factors, ranging from relatively modest to surprisingly high. Let’s break down the potential expenses involved, so you understand what to anticipate.

First, let’s understand the legal groundwork. California Probate Code § 6112 addresses the issue of interested witnesses. As the code states, an ‘interested witness’ (a beneficiary) triggers a legal presumption of duress or fraud. Unless there are two other disinterested witnesses, the beneficiary may lose their gift, taking only what they would have received under intestacy rules. Harvey’s situation highlights this perfectly.

Court Filing Fees & Service Costs

The initial cost is the court filing fee for the Heggstad petition itself. As of late 2024, this is around $445, but court fees are subject to change. Beyond that, you’ll need to formally serve notice of the petition on all interested parties – heirs, beneficiaries named in the Will, and anyone else with a potential claim to the estate. Service fees will depend on the number of parties and the method of service (personal service by a professional process server is typically required and costs around $30-$100 per person).

Attorney’s Fees – The Largest Variable

The bulk of the cost will be attorney’s fees. Many attorneys charge by the hour, and a Heggstad petition can be quite complex, often involving extensive legal research, drafting of pleadings, discovery (gathering evidence), and court appearances. Hourly rates for probate attorneys in Southern California typically range from $350 to $650 per hour, or even higher for experienced counsel.

A relatively straightforward Heggstad petition, where the issues are clear and the interested parties don’t vigorously oppose the petition, might require 20-40 hours of attorney time, translating to a legal fee of $7,000 to $26,000. However, if the case is contested—meaning heirs object to the Will’s validity—the hours can easily climb to 80, 100, or even more, resulting in legal fees exceeding $30,000-$65,000+.

Evidence Gathering & Expert Witness Fees

To successfully petition the court, you’ll need to present compelling evidence to overcome the presumption of fraud or duress. This could include affidavits from the testator’s friends, family, and medical professionals attesting to their mental capacity and the fact that the Will accurately reflects their wishes. Gathering this evidence can require significant investigation and potentially the cost of obtaining copies of medical records.

In some cases, you might need to hire an expert witness—a forensic document examiner or a psychiatrist—to provide testimony. Expert witness fees can range from $300 to $1,000+ per hour, adding substantially to the overall cost.

Court Reporter Fees

If a hearing is held, you’ll need to hire a court reporter to create a transcript of the proceedings. The cost of a court reporter is typically around $200-$400 per hour, depending on the length of the hearing.

The CPA Advantage

As an Estate Planning Attorney and a CPA with over 35 years of experience, I can tell you that the potential tax implications of a failed Will are often overlooked. If Harvey’s mother had a properly executed Will and assets held outside of a Trust, a disinheritance caused by the invalidation of that Will could significantly impact capital gains taxes. Without proper planning, assets may not receive the critical “step-up in basis,” leading to a substantial tax bill for the beneficiaries. My dual expertise allows me to address both the legal and the tax consequences of estate administration, offering a comprehensive solution.

Cost-Saving Strategies

While a Heggstad petition can be expensive, there are steps you can take to minimize costs. First, gather as much evidence as possible on your own before retaining an attorney. Second, attempt to reach a settlement with any objecting parties. A negotiated resolution is always cheaper and faster than a contested court battle. Finally, choose an attorney who is experienced in Heggstad petitions and has a clear understanding of your goals and budget.

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 could be a viable, and less expensive, alternative if the estate’s value is below that threshold. Additionally, including a self-proving affidavit—as outlined in Probate Code § 8220—allows the Will to be admitted to probate without the testimony of the subscribing witnesses, significantly accelerating the court’s approval process and reducing attorney’s fees.

What does a California probate court look for when interpreting testamentary intent?

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.
