there is already another topic in this board about this possibility and there are answers there:
https://bitcointalk.org/index.php?topic=1825035.0also this is what the developer said:
With the current version, the only way is to choose a server that you trust to be on the side of the fork you want. (disable auto-connect)
Right after the hard fork, we will be able to make a new release, that includes a checkpoint, because the block headers will differ.
Thanks for this one dude. I am also interested to what will happen in our coins when the hardfork happens because I also use Electrum as my main desktop wallet. It is so good to see that the developer is still involved in this project and he finds time to answer question here in Bitcointalk. I'll just have to monitor this section for more information for the hardfork and its effect to our beloved wallet.
