Wash. Rev. Code § 58.17.165
Every final plat or short plat of a subdivision or short subdivision filed for record must contain a certificate giving a full and correct description of the lands divided as they appear on the plat or short plat, including a statement that the subdivision or short subdivision has been made with the free consent and in accordance with the desires of the owner or owners.
If the plat or short plat is subject to a dedication, the certificate or a separate written instrument shall contain the dedication of all streets and other areas to the public, and individual or individuals, religious society or societies or to any corporation, public or private as shown on the plat or short plat and a waiver of all claims for damages against any governmental authority which may be occasioned to the adjacent land by the established construction, drainage and maintenance of said road. Said certificate or instrument of dedication shall be signed and acknowledged before a notary public by all parties having any ownership interest in the lands subdivided and recorded as part of the final plat.
Every plat and short plat containing a dedication filed for record must be accompanied by a title report confirming that the title of the lands as described and shown on said plat is in the name of the owners signing the certificate or instrument of dedication.
An offer of dedication may include a waiver of right of direct access to any street from any property, and if the dedication is accepted, any such waiver is effective. Such waiver may be required by local authorities as a condition of approval. Roads not dedicated to the public must be clearly marked on the face of the plat. Any dedication, donation or grant as shown on the face of the plat shall be considered to all intents and purposes, as a quitclaim deed to the said donee or donees, grantee or grantees for his, her or their use for the purpose intended by the donors or grantors as aforesaid.
