the uncle is the one that would create the deed. if you are married, from what it sounds like as to how it is being transferred, it would be community property so your husband could argue for 1/2 of your share, or the value anyway. If it is just you and the brother, that would mean husband would have a claim to a 1/4 share interest.
Before you do anything like this, you need to speak with a tax professional who can review the situation to determine who, if anybody, is going to owe taxes on this transfer.
