If the judgment is for a partition of the land, it shall state the number of shares into which the land is to be divided, and shall appoint not more than three (3) discreet freeholders, not related to the parties by consanguinity or affinity, to make partition according to the judgment. Either party may object to any master for cause, and, in case the objection is sustained, the place shall be filled by another appointment. If any vacancy occurs among the masters, the chancellor may fill the vacancy at any time by written appointment.
