Councillor Alby Walker, who quit the BNP in February, made the complaint to Stoke-on-Trent City Council's top legal officer.
Mr Walker, pictured, alleges that current BNP group leader councillor Michael Coleman and BNP councillors Philip Sandland, Steve Batkin and Anthony Simmonds breached the members' code of conduct.
The allegation relates to recent campaigning ahead of elections.
It states party activists distributed a newspaper, with a picture of Mr Walker's wife without permission.
Councillor Ellie Walker left the party last month to join her husband as a non-aligned councillor.
She said at the time that the BNP leadership had mounted a smear campaign against her husband, who is running against the far-right party's national deputy leader, Simon Darby, for the Stoke-on-Trent Central Parliamentary seat in the General Election.
Mr Walker said: "This complaint arises from the BNP distributing 18,000 newspapers with Ellie's photograph prominently displayed on the front page, promoting BNP policy, even though at the time she was not part of the BNP group.
"The four BNP councillors were identified as delivering this newspaper by several residents and two serving city councillors."
Mr Coleman told The Sentinel the BNP distributed the newspapers at the end of March, and he was not aware at the time Mrs Walker had left the party.
