I had heard that all who own bitcoins will get bitcoin cash, and since I had my coins already for years, sitting in an electrum wallet, I thought I was ready for this.
But now I started to read about this, how to gain Access to these coins and it was written that I would need the seed phrase of electrum wallet. Well, you know what, I never realized it is important, I just had the wallet.dat file in a safe Place, and remembering the password I need to enter when making any transfers. This way I was always able to gain Access to the wallet whenever I reinstalled Windows, or changed my Computer, just downloaded my personal wallet.dat file and installed electrum.
So I didn't care that I had long time ago forgot the seed phrase paper somewhere. Had I known I would probably have moved the btc to a new wallet and have the seed phrase in a safe Place but as it is, I didn't do that.
I'be been holding coins for years but without the seed phrase, is there any way to gain Access to the bitcoin cash??
Don't worry, you didn't lose your Bitcoin Cash.
1) Create a fresh Electrum wallet (make sure to have a copy of your old wallet.dat ready as well!)
2) Backup the fresh wallet.dat file.
3)
Write down the seed phrase 
4) Send your BTC from your old wallet to your fresh wallet.
5) Wait for your BTC to arrive in your fresh wallet. Your old wallet now only contains BCH. Your fresh wallet now only contains BTC.
6) If possible, install Electron Cash (note the name Electron instead of Electrum) on a separate device. If you don't have a second device, remove the fresh wallet file from your current device
but make sure you have both the backup and the seed phrase.7) If you install Electron Cash on the same device where you used for Electrum before, it should automatically import the old wallet.dat file. Otherwise import the old wallet.dat file manually.
I think that about covers it.
