W. Va. Code § 3-6-5
The provisions of article one of this chapter relating to elections generally shall govern and control arrangements and election officials for the conduct of elections under this article. The following rules and procedures shall govern the voting for candidates in general and special elections:
(a) If the voter desires to vote for an official write-in candidate, the voter shall: write with ink or other means or affix a sticker or label or place an ink-stamped impression of the name of an official write-in candidate for an office for whom he or she desires to vote in the space designated for write-in votes for the particular voting system or for paper ballot systems, write or place the name and office designation in any position on the face of the ballot which makes the intention of the voter clear as to both the office and the candidate chosen.
The Secretary of State may proscribe devices for casting write-in votes which would cause mechanical difficulty with voting machines or electronic devices or which would obliterate or deface a paper ballot or any portion thereof, but the Secretary of State shall preserve the right to vote by a write-in vote for those candidates who have filed and have been certified as official write-in candidates under the provisions of section four-a of this article.
