InBev is seeking a legal ruling that declares shareholders can remove Anheuser's 13 board members without giving cause, the Financial Times reported.
Anheuser's board has not responded to InBev's $46 billion purchase offer, although sources close to the company said it was preparing to reject the bid.
Anheuser's Chief Executive Officer August Busch IV told InBev, before the offer was made, that Anheuser was "not for sale" the Times reported.
InBev has been seeking shareholder support, claiming it would not change the traditions of the company, the Times reported.
