Ptolemy XII's will named Cleopatra VII and Ptolemy XIII joint heirs under Roman protection, and the heirs went to war
Ptolemy XII Auletes held Egypt with Roman backing. His will named two heirs to rule together: the elder of his two sons, Ptolemy XIII, and the elder of his two daughters, Cleopatra VII. Caesar records that the king called on the Roman people, by all the gods and by his treaty with Rome, to see the will carried out. Two copies were made. His envoys took one to Rome for the state treasury; because of unrest in Rome it was lodged with Pompey. The other was kept sealed in Alexandria. The king died in early 51 BC. The Senate accepted the role of executor and named Pompey guardian of the boy king. Three years later the heirs were at war. Cleopatra was driven out in 48 BC, raised an army in Syria and faced her brother's forces at Pelusium. Pompey, defeated by Caesar, landed in Egypt and was killed on the orders of the king's ministers Pothinus and Achillas. Caesar came to Alexandria and was besieged there by the king's army. Ptolemy XIII drowned in the Nile while fleeing after his defeat. Cleopatra kept the throne. Neither copy of the will survives; the terms are known from Caesar's Civil War, Book 3, chapter 108.
Naming co-heirs who must share control, and an outside guarantor to enforce it, gives the guarantor the deciding vote when the heirs fall out.
Smith's Dictionary says the Senate accepted the will and made Pompey guardian ( Wikipedia says the Senate was occupied and Pompey alone approved it ( Smith dates Ptolemy XIII's drowning to late 48 BC or early 47 BC (same Smith URL).
