Elton's ex-wife recently launched a legal action against the performer at the high court.
Renate Blauel is seeking an injunction about the former Reg Dwight. She has kept a low profile since the divorce in 1988, but Elton has spoken of the ''guilt and regret'' over the hurt he caused.
The reason for the legal action isn't known, but such measures generally deal with privacy concerns or the publication of personal material.
Renate's lawyer confirmed papers had been filed but said his client ''hopes to resolve the matter privately and amicably.''
As of press time, there has been no comment from Elton's representatives.
