With or without an attorney, the cost is going to be $435. You'll need to prepare a complaint and file it in Superior Court. If you need to pay a process server to personally serve any defendants, add around $80 per defendant for that cost. Any costs after that will be determined by whether there is discovery conducted, jury fees paid, and any other service fees you have to pay.
BTW, merely paying delinquent property taxes does not by itself create title adverse possesion.
To establish title by adverse possession, the claimant must establish possession by actual occupation under such circumstances as to constitute reasonable notice to the owner, possession which is hostile to the owner's title, a claim to the property as his own, either under color of title or claim of right, possession which is continuous and uninterrupted for five years, and payment of all of the taxes levied and assessed upon the property during the period.

My colleagues are correct. The "costs" to file the complaint and to have it served as well as to file and record a notice of lis pendens with the County Recorder's Office will be minimal, but the likelihood of success for an adverse possession claim (even with an attorney) is very small.
The elements necessary to establish ownership of real property by adverse possession in California are as follows: “(1) the payment of taxes, (2) actual possession which is (3) open and notorious, (4) continuous and uninterrupted for five years, (5) hostile and adverse to the true owner's title, and (6) under either color of title or claim of right.” (California Maryland Funding, Inc. v. Lowe (1995) 37 Cal.App.4th 1798, 1803.)
