Washington Revised Code Title 61. Mortgages, Deeds of Trust, and Real Estate Contracts § 61.30.110. Forfeiture may be restrained or enjoined

(1) The forfeiture may be restrained or enjoined or the time for cure may be extended by court order only as provided in this section. A certified copy of any restraining order or injunction may be recorded in each county in which any part of the property is located.

(2) Any person entitled to cure the default may bring or join in an action under this section. No other person may bring such an action without leave of court first given for good cause shown. Any such action shall be commenced by filing and serving the summons and complaint before the declaration of forfeiture is recorded. Service shall be made upon the seller or the seller's agent or attorney, if any, who gave the notice of intent to forfeit. Concurrently with commencement of the action, the person bringing the action shall record a lis pendens in each county in which any part of the property is located. A court may preliminarily enjoin the giving and recording of the declaration of forfeiture upon a prima facie showing of the grounds set forth in this section for a permanent injunction. If the court issues an order restraining or enjoining the forfeiture then until such order expires or is vacated or the court otherwise permits the seller to proceed with the forfeiture, the declaration of forfeiture shall not be given or recorded. However, the commencement of the action shall not of itself extend the time for cure.

(3) The forfeiture may be permanently enjoined only when the person bringing the action proves that there is no default as claimed in the notice of intent to forfeit or that the purchaser has a claim against the seller which releases, discharges, or excuses the default claimed in the notice of intent to forfeit, including by offset, or that there exists any material noncompliance with this chapter. The time for cure may be extended only when the default alleged is other than the failure to pay money, the nature of the default is such that it cannot practically be cured within the time stated in the notice of intent to forfeit, action has been taken and is diligently being pursued which would cure the default, and any person entitled to cure is ready, willing, and able to timely perform all of the purchaser's other contract obligations.
