I am a lawyer in CT and practice in this area of the law.  you are permitted to disclaim your rights to property that is to be distributed in probate, such as under a will.  I suggest that you truly think about the inheritance right that you were given and decide whether you really want to relinguish that right to the property.  there may be ways to resolve disputes that have not been thought of or posed.  if your siblings cannot agree on a price then perhaps once of them or you would buy the other's interest in the property to end the dispute.  There are other methods that can work however, if you want to disclaim your rights you can file a letter with the probate court and it will take notice accordingly.
