You truly only know someone when you deal with money. A partner’s true character is revealed when a dramatic thing occurs such as one the four extremes below:
1) More money is made than expected (including an astonishing success)
2) Less money is made than expected (including a staggering loss)
3) More workload is demanded than expected
4) Less workload is required than expected
Unexpected, extreme results could cause partners to break up. The best way to survive and prosper is for the partners to agree to the terms and conditions of the partnership and spell as much of it in writing. Then keep the communication open to reinforce the duties and responsibilities of each of the parties.
