When a small claims court judgment in California is not paid within 30 days, the plaintiff can file a lien on the debtor's real property. Besides the amount awarded, the debtor must pay court fees incurred for the writ of execution, debtor's examination and abstract of judgment, fees from the county recorder related to the abstract of judgment and sheriff fees. When the debtor refinances or sells his property, the lienholder generally gets her money with interest automatically.

我專門搜的加州的CASE，感覺符合common sense，隨便給人加lien豈不沒王法了？
