Standard multi-signature transaction BitcoinCore I created a transaction with a script for a Multi-Signature in the form of 


M &lt;A pubkey&gt; [B pubkey] [C pubkey...] N OP_CHECKMULTISIG


It is documented (https://bitcoin.org/en/developer-guide#multisig) that this type of script would belong to the standard transaction types.

When i put that transaction into Bitcoin-CLI via decoderawtransaction, it says:


"vout": [
    {
      "value": 0.00250000,
      "n": 0,
      "scriptPubKey": {
        "asm": "2 &lt;PublicAdress 1&gt; &lt;PublicAdress 2&gt; &lt;PublicAdress 3&gt; 3 OP_CHECKMULTISIG",
        "hex": "XXX",
        "type": "nonstandard"
      }
    }, 


I then sent the transaction via sendrawtransaction and it is sent, accepted and mined successfully to the Blockchain but it seems to be invisible for my wallet.

Also when i send such a transaction to my BitcoinCore wallet, Bitcoin Core doesn´t notify me about it. 

Is there simply no support in Bitcoin Core for that type of MultiSig transactions or am i doing anything wrong?
Bitcoin Core will be default only treat M-of-N multisignature outputs as "yours" (contributing to your balance) if you own private keys to all N public keys. This is to prevent showing something as a balance which could be spent from under you.

If you instead of using a raw multisig output use P2SH the same rule applies, but in that case you're able to use importaddress to mark the outputs as yours regardless of whether you have access to the keys.

Once the outputs are treated as yours, you can use signrawtransaction to fully or partially sign for them.
