Questions answered? Let's get started!
Under Cal. Civ. Code 8182, a real property owner can record a notice of completion at any time up to 15 days after the date of completion on a work of improvement. The notice of completion is an important document in the California mechanic's lien process, as it limits the time a claimant is allotted to file a claim of lien. A direct contractor has 60 days after the owner's filing of a notice of completion to file a claim of lien. If no notice of completion is filed within 15 days of completion of the project, the contractor has 90 days to file a claim of lien.
A lawful notice contains the name and address of each owner and the nature of the owner's interest or estate in the property, as well as the construction lender's name and address, if applicable. The notice gives the completion date and a general description of the work of improvement, as well as a legal description of the property on which the improvement is made, along with the property's address.
In California, a notice of completion may relate to the completion of a contract for work on an improvement as a whole or a contract for a portion of work. In either instance, the notice states the name and address of the direct contractor and the nature of the notice.
The notice is signed and verified by the owner, who is the person (or persons) with titled interest in the property. This may or may not be the person occupying the property. The notice may be signed by an owner's successor; if this is the case, the notice must state the name and address of the transferor.
Within 10 days of recording a notice of completion, the owner must serve copies to the direct contractor and any claimant who has given the owner preliminary notice. Failure to give notice to the contractor or a claimant that a notice has been filed within 10 days of recording the notice renders the notice ineffective to shorten the length of time a contractor has to file a claim of lien.
The method of serving notice on the requisite parties must comply with Section 8100 of the Civil Code of California. Proof of service of notice is required along with the notice when recording. The declaration of proof of service evidences the method of serving notice and is signed by the person serving notice and acknowledged in the presence of a notary public.
Record a notice of completion in the recorder's office of the county where the property is situated. Ensure that the document is in recordable form as established by Cal. Gov. Code Sec. 27361.6.
Consult a lawyer with questions about notices of completion, mechanic's lien laws, or for any other issues regarding real property in the State of California.
Important: Your property must be located in Contra Costa County to use these forms. Documents should be recorded at the county recording office listed above.

Might be adequate if I was desperate. Formatting screams amateur hour -- not a legal issue but likely to invite closer scrutiny when filed. Instructions were supposed to be county-specific but directed me to call the recorder to ask them how to fill out part of the form. Not planning to use the form and would not purchase it again. I could probably do better by uploading some examples and the original mortgage from the Recorder's website into Claude along with the transaction-specific information and asking Claude to prepare a more professional release.
Aaron, we’re sorry the form and instructions did not meet your expectations. Your order has been canceled and your payment refunded. We appreciate your feedback and wish you the best with preparing the release in the way that works best for your situation.

The transfer deed documents are laid out the way county offices need, but I don't like the requirements so I'm going to leave a bad review.
Well, thanks we guess.

The instructions and example for filling out the form were very clear and detailed making the whole process fairly easy. An attorney I talked to wanted $200 to fill out this simple form. I haven't tried to file it yet but I will let you know if there are any issues. Really a great deal. $20 vs $200.
We appreciate your business and value your feedback. Thank you. Have a wonderful day!

My overall experience was positive. Little trouble uploading documents but resolved. I had two mineral deeds to file in Arkansas, two different counties, exactly the same form, only difference being property description; one was completed, one was canceled. I emailed to inquire why and the reply was in an automatic email indicating that email address was not monitored and if further action would be taken on Deeds.com part, I would be notified. Other than that, I would recommend their services to avoid using snail mail.
We appreciate your business and value your feedback. Thank you. Have a wonderful day!

I didn't care for it because I was having to do other things in between filling it out and all of a sudden it would not allow me back in it to make changes. Luckily I had saved it and then had to do FILL/SIGN option which looks ugly but that was the only way I could add what I needed.
We appreciate your business and value your feedback. Thank you. Have a wonderful day!

Excellent service, great feedback and recommendations by the deed preparer, and I really appreciate the personalized service. The website is amazing, everything is well thought out, and all messages are saved, clear and easy to read. I wish my website was so easy to navigate! Seriously, the person who worked on my account is awesome. They made recommendations about what to include and what not to include. They didn't make me feel dumb for asking questions about out-of-state service and filing procedures, and I will be using Deeds.com exclusively on my cases. Five stars !
We appreciate your business and value your feedback. Thank you. Have a wonderful day!

Easy to use and get forms I needed. Corporate need for an invoice/receipt could be a bit easier - have to print screen to get any info.
Thank you for your feedback Dave, we really appreciate it.
