TWO OWNER-FILED PRODUCTS
County Assessment Appeals office
Formal Appeal Package
$45
County filing fee is separate
Valuvia prepares the owner-filed formal application. After verified filing and payment, the remaining evidence and hearing materials are unlocked.
Five steps
- Choose the Prop 8 Informal and/or Formal Appeal package, then verify the property, APN, assessment year, and owner information.
- Review the Valuvia prepared county form. Print and sign it; for a formal appeal, include the county filing fee.
- Mail the signed form using trackable delivery. Keep a complete copy and meet the county deadline (the county’s published formal appeal filing window). You can also choose to file online for faster confirmation if your county publishes an official filing portal.
- Upload the county filing receipt by clicking the My order link in your order emails, or go to My orders (https://www.valuvia.net/account). Mailing proof alone is not a county filing receipt.
- After Valuvia verifies the receipt, the Prop 8 Informal Request Package unlocks free; the Formal Appeal Package unlocks after you pay the service fee.

Essential answers
Products and filingWhat does Valuvia provide?
Valuvia prepares owner-filed property-assessment review documents and supporting evidence. Valuvia is not a county agency, law firm, tax adviser, appraiser, or filing representative.
Products and filingWhich packages are available?
Eligible Riverside, Los Angeles, and San Diego County homeowners may choose the free Prop 8 Informal Request Package (Riverside and Los Angeles informal packets today) or the $45 Formal Appeal Package.
Products and filingWhen do I pay Valuvia?
Not before filing. First, download the county form, review, sign, and file it yourself. Upload the county filing receipt; after Valuvia verifies it, pay to unlock the remaining documents.
Products and filingDoes the county charge a filing fee?
Informal assessor review is available directly from the county at no cost. Formal appeals may require a separate county fee. Check the current official county instructions before filing.
Products and filingDoes Valuvia file for me?
No. You review, sign, and file online or by paper mail. Online filing usually gives faster confirmation; mail is simpler but slower and can be delayed or lost.
Products and filingWhat filing proof should I upload?
Upload the county receipt or confirmation showing the request or application was filed. A postal receipt alone proves mailing, not county filing.
Products and filingIs an informal Prop 8 request the same as a formal appeal?
No. The assessor handles an informal request; the county assessment appeals office handles a formal appeal. An informal request generally does not preserve the formal deadline.
Products and filingIs a reduction guaranteed?
No. The county decides. A formal appeals board may lower, leave unchanged, or raise a value subject to California law and Proposition 13 limits. Estimated savings is the best possible figure from the numbers shown, not a guaranteed result. Valuvia is not responsible for the county’s decision or for tax you still owe.
Products and filingHow do I reach a person?
Call Valuvia Customer Care at (888) 805-7076, email support@valuvia.net, or use Send a support email on this page. Ask Val is AI-assisted and cannot make account, payment, refund, or filing decisions.
Products and filingWhich counties does Valuvia support?
Paid packages are available for eligible residential properties in Riverside, Los Angeles, and San Diego Counties. Informal Prop. 8 packets are currently published for Riverside and Los Angeles. San Diego paid service is the Formal Appeal Package.
Products and filingCan I correct an error?
Yes. Contact Customer Care promptly with the order number, corrected fact, and supporting record. Do not file or rely on information you know is inaccurate.
Products and filingHow do refunds work?
Formal Appeal ($45): within six months of the Valuvia charge, if the county does not reduce the assessment or the appeal is unsuccessful, you may request a refund of that fee with the county decision letter or other official evidence. Prop. 8 Informal: the package is free, so there is no fee to refund. County fees are never refunded by Valuvia.
