What this form asks for

The AI fills all of it, from your answers or your documents.

Form DE-165, the Notice of Proposed Action, is a legal document used in California probate cases when an estate is administered under the Independent Administration of Estates Act. The personal representative uses this form to inform heirs and other interested parties of a specific action they intend to take without court supervision, such as selling real property. This notice gives recipients the opportunity to either consent to the action or formally object, which would then require the representative to seek court approval. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

13 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Case Number Consistency Across Pages

This check verifies that the 'CASE NUMBER' entered on page 1 is identical to the 'CASE NUMBER' entered on page 2. Mismatched case numbers can lead to filing errors and confusion, potentially invalidating the notice. If the numbers do not match, the form submission should be flagged for correction to ensure document integrity.

Decedent Name Consistency Across Pages

This validation ensures that the name of the decedent in the 'ESTATE OF' field is consistent on both page 1 and page 2. The decedent's name is a primary identifier for the case, and any discrepancy could cause the document to be misfiled or rejected. This check prevents administrative errors and ensures legal accuracy.

Exclusive Authority Selection

Validates that exactly one of the two authority options in Item 2 ('full authority' or 'limited authority') is selected. The personal representative must operate under one specific type of authority, and selecting both or neither is ambiguous and legally invalid. A failure in this check requires the user to make a single, clear choice.

Future Action Date Requirement

This check ensures the date provided in Item 3 ('On or after (date)') is a valid date format and is set in the future. A notice of proposed action must give recipients adequate time to respond before the action is taken. A past or invalid date would render the notice defective, so this validation is critical for legal compliance.

Action Description Completeness

Verifies that the proposed action is described by either filling in the text area in Item 3 or by checking the box indicating the description is in 'Attachment 3'. The notice is meaningless without a clear description of the action being proposed. If both are empty, the form is incomplete and must be corrected to inform recipients properly.

Conditional Real Property Information

If the 'Real property transaction' box in Item 4a is checked, this validation ensures that either a monetary value is entered in Item 4b or the 'No inventory yet' box is checked. For real property sales, the value is a material term of the transaction that must be disclosed. An error is flagged if box 4a is checked but neither of the sub-options is completed.

Common Mistakes in Completing DE-165

The ones the AI is built to catch.

Providing an Ambiguous or Incomplete Action Description
In Item 3, filers often provide a vague description of the proposed action, such as 'sell real property.' This is a mistake because the law requires a description of all material terms, including the sale price and any broker commissions. Ambiguity can lead to objections or future legal challenges, as heirs can claim they didn't have enough information to provide informed consent. To avoid this, be highly specific and detail all financial aspects of the transaction.
Incorrectly Selecting the Representative's Authority
A frequent error is checking the wrong box in Item 2 regarding the personal representative's authority. Filers must accurately select either 'full authority' (2a) or 'limited authority' (2b) based on the official Letters of Administration issued by the court. Selecting the incorrect authority misrepresents the representative's legal power, which can invalidate the notice and void any action taken based on it.
Setting an Incorrect or Insufficient Notice Date
The date entered in Item 3, specifying when the action can be taken, must be at least 15 days after the notice is mailed. People often miscalculate this date or even enter a past date, which invalidates the entire notice period required by law. This forces the representative to restart the process, causing significant delays in administering the estate. Always calculate the date carefully, adding extra days for mail delivery.
Entering Incorrect or Incomplete Case Information
The header section containing the court, estate name, and case number is often filled out with typos or missing information. This happens due to simple data entry errors when copying from other documents. Such mistakes can lead to the notice being rejected by the court clerk or misfiled, delaying the legal process. Using a tool like Instafill.ai can help prevent these errors by auto-filling and validating case information from a central record.
Omitting the Address for Objections
Filers sometimes forget to complete Item 5a on the second page, which specifies the name and address where objections must be sent. This is a critical error as it effectively denies recipients the ability to formally object, since they don't know where to send the form. A notice without this information is legally defective and can be challenged, potentially nullifying the proposed action.
Failing to Flag a Real Property Transaction
When the proposed action involves selling or granting an option on real estate, box 4a must be checked and item 4b must be completed. Forgetting to check this box is a significant oversight that fails to provide the specific, heightened notice required for real property transactions. This error can create a cloud on the property's title and may allow an heir to challenge the sale later on.
Mishandling the Property Value in Item 4b
Item 4b requires the property's value as stated in the official, filed probate inventory, not a recent appraisal or market estimate. A common mistake is to enter an estimated value or leave it blank when an inventory value exists. If no inventory has been filed, the 'No inventory yet' box must be checked instead. Incorrectly reporting this value can be misleading and may trigger unnecessary objections from beneficiaries.
Missing Signature of Representative or Attorney
An unsigned Notice of Proposed Action has no legal effect. The personal representative or their attorney must sign at the bottom of page two before the notice is mailed to any interested parties. Forgetting this final step renders the document invalid, meaning any action taken is unauthorized and the entire notice process must be repeated.
Mismatched Use of Attachments
Filers may describe the proposed action in a separate document but forget to check the 'described in an attachment' box in Item 3, or vice-versa. This mismatch creates confusion for the recipient, who may not know to look for an attachment or may be confused by a checked box with no corresponding document. This can lead to the notice being deemed incomplete or legally insufficient.
Confusing the 'Attorney For' and 'Estate Of' Fields
In the header, the 'ESTATE OF' field is for the decedent's name, while the 'ATTORNEY FOR' field is for the name of the living client (the personal representative). People often mistakenly put the decedent's name in both fields or the attorney's own name in the 'ATTORNEY FOR' field. This creates clerical confusion and may require the form to be corrected and re-filed, causing delays. AI-powered tools like Instafill.ai can help by populating these fields correctly based on case data.

DE-165 has a Form Complexity Index of 34 out of 100, in the basic tier: 38 fillable fields across 2 pages. Instafill.ai's AI fills it in under a minute, with every field there for you to review before you download.
What is the purpose of the Notice of Proposed Action (Form DE-165)?
This form is used by the personal representative of an estate to inform heirs and beneficiaries about a specific action they intend to take, such as selling property, without court supervision. It gives you the opportunity to either consent to or object to the action.
Why did I receive this form?
You received this notice because you are an heir, beneficiary, or other interested party in the estate. The personal representative is legally required to notify you of the proposed action before it is taken.
What are my options after receiving this notice?
You have three options: you can formally consent by signing and returning the form, you can formally object by signing and returning the objection portion, or you can do nothing. If you do not object in writing by the deadline, you are legally treated as if you have consented.
How do I object to the proposed action?
To object, you must complete and sign the 'Objection to Proposed Action' section on the second page and mail it to the personal representative at the address listed in item 5a. Your written objection must be received before the date specified in item 3.
What happens if I object?
If you object, the personal representative cannot take the proposed action without court supervision. They will have to file a petition with the court and get an order allowing the action.
What happens if I do nothing?
If you do not send a written objection or get a court order by the deadline, you lose your right to object later. You will be treated as if you consented, and the personal representative can proceed with the action.
What is the difference between 'full authority' and 'limited authority' in item 2?
Full authority allows the personal representative to take most actions, including selling real estate, without court supervision. Limited authority is more restrictive and requires the representative to get court approval for major actions like selling real property.
The notice is about selling real property. What does 'without court supervision' mean for the sale?
It means the sale will not be presented to a court for confirmation. This is important because there will not be a court hearing where higher bids for the property can be presented and potentially accepted.
Who fills out this form?
The personal representative of the estate (or their attorney) fills out and sends this form to all required parties. The recipients then fill out the objection or consent portion if they choose to respond.
Where can I find the deadline to respond?
The deadline is stated in item 3. Your objection must be received by the personal representative on or before the date listed in that box, or before the action is taken, whichever is later.
Who should I contact if I need more information about the proposed action?
Item 7 on the form provides the name and telephone number of a person you can call for more information regarding the details of the proposed action.
Can AI tools help me fill out this form?
Yes, if you are the personal representative, services like Instafill.ai can use AI to accurately auto-fill form fields. This helps save time and reduces the chance of errors when preparing the notice.
