Special retention is the right of withholding or retaining property of goods which are in one's possession under a contract, till indemnified for the labor or money expended on them. 2. General retention is the right to withhold or detain the property of another, in respect of any debt which happens to be due by the proprietor to the person who has the custody; or for a general balance of accounts arising on a particular train of employment.
