Unlawful detainer filings, which are the legal documents landlords can use in Washington state to evict tenants who have violated rental agreements, have jumped in Spokane County this year by 250 cases, or about one-fifth. Through the first 10 months of 2013, landlords filed about 1,440 unlawful detainer cases in Spokane County Superior Court, says Gary Berg, deputy chief to the county clerk. During the same period in 2012 and 2011, Berg says, they filed about 1,190 and about 1,300 cases, respectively. While the number of filings is up, the volume is significantly lower than the highest recorded year for unlawful detainers in the last decade, which was just over 1,900 actions in 2004. Since the recession period began in 2007, the number of unlawful detainer actions has fluctuated, but has mostly remained in the 1,300 to 1,400 range.
