If the partners have agreed to intrust to a third person the designation of the share of each one in the profits and losses, such designation may be impugned only when it is manifestly inequitable. In no case may a partner who has begun to execute the decision of the third person, or who has not impugned the same within a period of three months from the time he had knowledge thereof, complain of such decision.
The designation of losses and profits cannot be intrusted to one of the partners. (1690)
