The bottom line is, you want a legal separation agreement that will protect you during a separation in case your spouse fails to live up to his/her obligations as outlined in the agreement. You want an agreement that will hold up in court should you have to go to court to have it enforced.
tribÂ·une 1. n. 1. An officer of ancient Rome elected by the plebeians to protect their rights from arbitrary acts of the patrician magistrates.
After a brief struggle, the patricians recognized the two (later ten) tribunes, but demanded that they would not veto military decisions. The tribunes were therefore some sort of anti-magistrates elected by the people's assembly (consilium plebis). The tribunes were also chairmen of the people's assembly, superseded the election of the aediles, and had to assist poor plebeians. In the fourth and third centuries, when the conflict between the patricians and plebeians was over, new functions were added: for example, the tribunes could convene a Senate meeting and arrest magistrates.
