Section 1. Amendment of Use Restrictions. Articles B and C of this instrument which relate to use of the Lots in the Subdivision may be amended and changed by the written consent of the owners of the fee title (in the case title is subject to a real estate contract, the vendees under the real estate contract shall be deemed to be owners of the fee title) of not less than sixty (60%) of all of the Lots in all of the Subdivisions which have been made subject to the provisions of this Declaration. For the purpose of amendment consent to an amendment by a fee owner shall be binding upon the owner and of any successors to the fee title for a period of six months after it is given for the purpose of calculating the percentage required for adoption of the consent. Consents required under this Section shall be delivered to the Community Organization which shall tabulate them. Its determination of the sufficiency of the consent shall be conclusive, and an amendment to Articles B and C shall be effective when a written Notice of Amendment signed and acknowledged by the president and secretary of the Community Organization is recorded in King County, Washington, stating that the requisite consent has been obtained and setting forth the amendment in its entirety.
