A Washington Order on Petition for Instruction (OPI) is an order issued by a Washington court that authorizes a trustee to sell real or personal property in a trust. This order allows the trustee to sell the property and distribute the proceeds to the beneficiaries of the trust. There are two types of orders: the general OPI, which applies to all trusts, and the specific OPI, which applies only to a designated trust. The general OPI is used to authorize the sale of real or personal property owned by the trust, and the specific OPI is used to authorize the sale of specific property owned by the trust. The OPI must be filed with the court and must include a petition for instruction, which outlines the legal basis for the sale of the property. The court will then review the petition and decide whether to approve the sale.
