If a stock split is coming soon and the company did not bother to consult shareholders before deciding to do the stock split, do I have the right to resist the split? How can I stop the stock split? Do I have to sue the company? I don't want any forward splits or reverse splits because they are useless to me. Stock splits also needlessly complicate my record-keeping.
As a stockholder you get to vote for board members and other corporate actions. You might even get a chance to vote on a stock split in some situations.
However, unless you own a ton of shares you will likely be outvoted because this is such a routine thing that most stockholders wouldn't and realistically shouldn't care about.
You can sue anyone you like, but in this case there is almost zero chance you would win because this is a standard practice and they don't owe you more say in the matter than the number of voting shares you own.
