Change in Deed name

Can any1 help me in knowing whether service tax would be applicable in case a company charges a fee in respect of change of name in the deed.

Suppose: M/s A real estate co. sold a residential property to Mr.B in the name of Mr.B.But after deed has been prepared Mr.B says Deed shuld contain the name of his wife also.Now M/s A real estate charges a fee for this.

will it attract service tax...
