DE-350, Gc 100 Petition And Order For Appointment Of Guardian Ad Litem Under The Probate Code Form
Use a DE 350, GC 100 PETITION AND ORDER FOR APPOINTMENT OF GUARDIAN AD LITEM UNDER THE PROBATE CODE template to make your document workflow more streamlined.
What the DE-350 and GC 100 form does
The DE-350 and GC 100 materials concern a petition and order for appointing a guardian ad litem under the California Probate Code. They help a probate participant present the appointment request, identify the matter and people involved, and obtain the signatures required for the document workflow. With signNow, a sender uploads the form, reviews detected fillable fields, assigns signer roles, routes the document, and preserves the completed PDF with an audit trail. Electronic preparation or signing does not itself constitute court filing, judicial approval, or appointment; California probate procedures control those actions.
Who uses the guardian ad litem form
Probate practitioners
California probate attorneys and self-represented petitioners use this form to request appointment of a guardian ad litem when a protected person’s interests require separate representation. They identify the proceeding, explain the appointment request, and coordinate signatures before submitting materials according to the applicable probate court’s procedures.
Probate participants
Court-appointed representatives and fiduciaries use the DE-350 and GC 100 materials to organize guardian ad litem appointment information for a specific probate matter. signNow can help prepare, route, and preserve signed records, but court filing, judicial action, and any required personal appearance remain governed by California court rules.

Upload: Upload the DE-350 or GC 100 PDF into signNow. Review: Auto-detect fillable fields and verify the probate information. Route: Send assigned fields to the petitioner or authorized signer. Archive: Store the signed PDF with its audit trail.

Privacy and disclosure pitfalls
The signed form may expose a protected person’s name, address, relationship details, or allegations when sent to unintended recipients or stored in an unrestricted folder. A signer may complete a signature field without a clearly documented intent or electronic-record consent, weakening the evidence supporting how the DE-350 was executed. Forwarded email links can allow the wrong person to access probate materials, especially when the recipient list includes family members, counsel, fiduciaries, or court personnel. Combining the petition, proposed order, exhibits, and audit certificate without access labels can disclose more information than each recipient needs.

Platform requirements for probate workflows
Prepare the DE-350 and GC 100 using signNow in Chrome, Firefox, Safari, or Edge on Windows 11 or macOS. Signers can use iOS or Android devices, provided their browser or signNow mobile app can open the assigned fields and display the complete document securely over TLS.
Browsers Chrome, Firefox, Safari, and Edge Desktop systems Windows 11 and macOS Mobile systems iOS and Android
Legal offices should use managed Windows 11 or macOS devices, current browser security updates, and controlled access to downloaded PDFs. Teams connecting signNow to case-management systems should review API, SSO, and retention requirements before deployment. Mobile signing can support participant access, but it does not replace California court filing instructions, judicial review, or any required in-person procedure.
DE-350 and GC 100 troubleshooting
These answers address document preparation, signature evidence, privacy, plan capabilities, and the boundary between signNow workflows and California probate filing.
Upload the official DE-350 or GC 100 PDF rather than a screenshot or incomplete scan. signNow can detect fillable fields after upload, but the sender must verify every detected field against the form and California probate instructions before routing it.
Use signNow’s assigned fields and audit trail to document signer intent, attribution, timestamps, and actions. ESIGN and UETA recognize qualifying electronic signatures, but court orders and official court filings remain statutory exceptions under 15 U.S.C. §7003.
Business includes legally binding eSignatures, templates, audit trails, mobile apps, ISO 27001, and SOC 2 Type II. Business Premium adds bulk send and kiosk mode, while Enterprise adds advanced signer authentication and formula fields.
Enable stronger authentication, such as SMS OTP or identity verification, when the matter contains sensitive protected-person information. Authentication supports attribution, but the sender must still confirm that the signer is authorized under the probate matter’s procedures.
Export the completed PDF and audit trail from signNow, then store them under the law firm or court matter’s retention policy. No single federal retention period in the provided authority specifically governs every California guardian ad litem record.
Electronic signing does not cure an incorrect caption, missing party, absent required signature, or improper filing method. Compare the completed DE-350 or GC 100 against the pending case and follow the California court’s current submission instructions.
