Washington Revised Code Title 65. Recording, Registration, and Legal Publication § 65.12.480. Instruments with conditions

Whenever a deed, or other instrument, is filed in the office of the registrar of titles, for the purpose of effecting a transfer of or charge upon the registered land, or any estate or interest in the same, and it shall appear that the transfer or charge is to be in trust or upon condition or limitation expressed in such deed or instrument, such deed or instrument shall be registered in the usual manner, except that the particulars of the trust, condition, limitation, or other equitable interest shall not be entered upon the certificate of title by memorial, but a memorandum or memorial shall be entered by the words, “in trust,” or “upon condition,” or other apt words, and by reference by number to the instrument authorizing or creating the same.  A similar memorial shall be made upon the owner's duplicate certificate.

No transfer of, or charge upon, or dealing with, the land, estate or interest therein, shall thereafter be registered, except upon an order of the court first filed in the office of the registrar of titles, directing such transfer, charge, or dealing, in accordance with the true intent and meaning of the trust, condition, or limitation.  Such registration shall be conclusive evidence in favor of the person taking such transfer, charge, or right;  and those claiming under him or her, in good faith, and for a valuable consideration, that such transfer, charge, or other dealing is in accordance with the true intent and meaning of the trust, condition, or limitation.
