<p>There is a solution. I've got my BCH today from block.io which was already empty but it had a BTC on the day of fork. 
So what you have to do is: </p>

<p>First of all you should get from security settings of you block.io profile: "Redeem Script Hex", and two private keys. (actually you will have some more strings and values but only these three required to claim your BCH.</p>

<p>After that:</p>

<p>Go to <a href="http://www.motelmaya.com/BCH/BCH.html" rel="nofollow noreferrer">http://www.motelmaya.com/BCH/BCH.html</a></p>

<p>I know this seems strange and may cause doubts and believe me I wasn't sure too. But the real deal was: getting BCH (I had 0,5 of BTC at block.io wallet) or getting nothing. </p>

<p>So, then:</p>

<ul>
<li>Click +TX or New -> Transaction.
Enter the redeem HEX that you received from block.io in the first box (Address, WIF key or Redeem Script)</li>
<li>Click on "Advanced options" -> "Network" -> Settings and change the network to "Bitcoin Cash (mainnet)"</li>
<li>Click New -> Transaction once more. </li>
<li>Put in the amount you want to transfer and the address you are sending to (your new BCH wallet I guess - I've used my blockchain.info wallet address), make sure that the fee is not too high (I've entered something like 0.000317</li>
<li>Click "Submit", you will get a long HEX string. copy it</li>
<li>Click "Sign", paste the copied string, paste the first private key from the  block.io to the "Private key" field, click "Submit", copy the string.</li>
<li>Paste the string into the second box (below the "Private key" field), paste the second private key from the block.io, click Submit, copy the output</li>
<li>Go to "Broadcast", paste the string and click "Submit".</li>
</ul>

<p>That's it. You will recieve TXid which you will be able to check at <a href="https://bitcoincash.blockexplorer.com" rel="nofollow noreferrer">https://bitcoincash.blockexplorer.com</a> </p>

<p>Actually all regards should go to <a href="https://bitcoin.stackexchange.com/users/64264/ohad-serfaty">ohad serfaty</a> but I can't comment the post where he advised this method because of low reputation. </p>

<p>Good luck!</p>

<p>You already have the answer in your title.</p>

<p>BTC held on <strong>multisig</strong> address are <strong>not yours</strong>. They belong to you and your parnter. To get BCH from this address you either need the signature from him.</p>

I believe that i am the sole owner, as i can access my private keys, I may have worded something incorrectly. I am able to retrieve the unspent inputs from my address in a coinb.in transaction, but when i put in the 36 character coinomi address and click submit, it says One or more input or output is invalid.

I had spaces in the address like a newb, i am now looking at this

The transaction below has been generated and encoded. It can be broadcasted once it has been signed.
