What is a ProveUp Hearing

I recently had a client, Emily, call me in absolute distress. Her mother had passed, leaving a hand-written codicil changing the beneficiaries of her trust. Emily had carefully filed everything with the court, only to have the judge at the “prove-up” hearing tell her it wasn’t enough. The judge demanded certified copies of the original trust, copies Emily hadn’t anticipated needing. The hearing was continued, costing Emily thousands in legal fees and, more importantly, delaying access to funds she desperately needed for her mother’s final expenses. This scenario is far too common.

As an Estate Planning Attorney and CPA with over 35 years of experience here in Escondido, I’ve seen countless estates needlessly complicated by misunderstandings surrounding the “prove-up” hearing in probate. It’s often the first real court appearance after someone passes, and it’s critical to understand what it is, what’s required, and how to avoid common pitfalls. My background as a CPA gives me a unique advantage in these cases – I not only understand the legal hurdles but also the tax implications of proper (and improper) estate administration, like the crucial step-up in basis for inherited assets.

What exactly is a Prove-Up Hearing?

A prove-up hearing isn’t about arguing the merits of the will or trust itself. It’s a procedural hearing where the court verifies that the documents presented – the will, the trust, and any codicils – are valid and legally admissible as evidence. The court needs to be satisfied that these documents are the genuine last testament of the deceased. Think of it as a formality, but one with serious consequences if you don’t prepare correctly. It’s not a trial; it’s a verification process.

What documents do I need to bring to the Prove-Up Hearing?

This is where Emily stumbled, and where most people make mistakes. Simply filing the documents with the court isn’t enough. You need to prove they are what you say they are. Generally, you’ll need:

• Certified copies of the original will or trust document: The court won’t accept photocopies. You need a certified copy from the attorney who drafted the document, or from the county recorder if it was previously recorded.
• A certified copy of the Death Certificate: This is self-explanatory, but easily overlooked in the rush of things.
• The Petition for Probate (Form DE-100): Make sure it’s properly executed and reflects the current status of the estate.
• The Notice of Hearing (Form DE-120) and Proof of Service: This proves that all interested parties were legally notified of the hearing. Probate Code § 1220 states if you missed a hearing because you weren’t told about it, the order may be void. The petitioner has a strict duty to mail the Notice of Hearing (Form DE-120) to all interested persons at least 15 days prior. A ‘Proof of Service’ missing from the file will stop the hearing immediately.
• An Affidavit Regarding Publication (if applicable): If certain heirs or beneficiaries are unknown, you’ll need to demonstrate that you’ve taken steps to locate them through publication.

What happens if someone objects at the hearing?

Even at a prove-up hearing, someone can object to the validity of the will or trust. Probate Code § 1043 gives you the right to object orally and request a continuance (typically 30 days) to file a written objection. However, be prepared – the judge won’t simply accept your objection without a reason. You need to articulate why you believe the document is invalid.

What if I need to present witness testimony?

Standard probate hearings are not typically “live witness” events. Probate Code § 1022 states that an affidavit or verified petition is received as evidence. If you want to put a witness on the stand, the judge will likely continue the matter to a separate evidentiary hearing or trial. This can significantly delay the process.

What about remote appearances via Zoom?

Code of Civil Procedure § 367.75 clarifies that California law now permanently allows for remote appearances in probate hearings, provided you give notice. However, the judge retains discretion to require specific personal appearances for evidentiary hearings or trials. Don’t assume you can always appear remotely.

What happens after the hearing – getting the actual Order?

This is another frequent source of frustration. California Rule of Court 3.1312 states that the judge generally does not write the order for you. The prevailing party is responsible for preparing the ‘Proposed Order’ and lodging it with the court before the hearing. If the judge grants your petition but there is no Order in the file to sign, you leave with nothing. Be proactive and have it ready!

What about clearing Probate Notes – the “Secret” Step?

Most hearing delays are caused by uncleared ‘Probate Notes.’ You cannot simply explain the issue to the judge in court; you MUST file a verified ‘Supplement to Petition’ in writing at least 2-3 court days before the hearing to satisfy the Probate Examiner. This addresses any outstanding questions or concerns the examiner has about the case. It’s a small step that can save you a lot of time and money.

What determines whether a California probate estate closes smoothly or turns into litigation?

California probate is designed to provide court-supervised transfer of property, yet cases often break down when authority is unclear, required steps are missed, or disputes arise over assets, notice, and fiduciary conduct. When the process is misunderstood, families can face avoidable delay, escalating conflict, and increased exposure to creditor issues, hearings, or litigation before the estate can close.

• Choices: Explore alternatives to probate.
• Details: Check specific considerations.
• Administration: Manage probate administration.

California probate is most manageable when authority is documented early, assets are classified correctly, and procedure is followed consistently from petition through closing. When the process is approached with realistic expectations about notice, claims, accounting, and dispute risk, the estate is more likely to move toward closure without avoidable conflict or delay.

Verified Authority on California Probate Hearings

• Oral Objections (The “Stop” Button): California Probate Code § 1043
  This is the most important statute for beneficiaries. It grants an interested person the right to appear at the hearing and object orally to the petition. Once an oral objection is made, the court generally must continue the hearing to allow time for written objections to be filed.
• Remote Appearances (Zoom/CourtCall): California Code of Civil Procedure § 367.75
  Modern probate hearings are often hybrid. This code section governs the right to appear remotely. While convenient, note that the court can typically require a physical appearance for “evidentiary” hearings where witness credibility is being judged.
• Affidavits as Evidence: California Probate Code § 1022
  Unlike criminal court, probate hearings rely heavily on paper. A verified petition or an affidavit is admissible as evidence in an uncontested probate hearing. This is why “clearing your notes” in writing is more important than your oral argument.
• Notice of Hearing Requirements: California Probate Code § 1220
  The court’s jurisdiction depends on this. The petitioner must mail notice of the hearing at least 15 days in advance to all interested parties. If the “Proof of Service” is not filed or is defective, the judge cannot legally hold the hearing.
• Lodging the Proposed Order: California Rules of Court 3.1312
  A common rookie mistake is showing up without the paperwork. The “Proposed Order” (the document the judge signs) should generally be lodged with the court before the hearing. If the judge approves your petition but has nothing to sign, your Letters cannot be issued.
• Proving the Will (Witnesses): California Probate Code § 8220
  If a Will is contested, or if it is not “self-proving” (lacking a proper attestation clause), the court may require the testimony of a subscribing witness at the hearing to prove the Will is authentic.
