Good that you finally figured out how to use Google. And whyAdded: BTW my paying the taxes on it was not required. It just cut the time for AP from 10 to 7 years per Washington law.
All one wanted to know about Adverse Possession:
didn't you post what you found there, that shows exactly what I said and which you and someone else on here found so unbelievable:
"PAYMENT OF PROPERTY TAXES
Some states require the trespasser to have paid the taxes on the property for the statutory time period. If all the other requirements are met except the tax payment, a court will usually grant a prescriptive easement to use the property to the trespasser, instead of ownership through adverse possession. (See "Easements," below)."
As for it being "all one wanted to know about adverse possession",
it's titled "California Adverse Possession", from a CA govt DOT website, dumb ass.
