Charles IV of France married Blanche of Burgundy in 1308, and they had two children Philip born 1314, and Joan born 1315, in 1322, Charles annulled their marriage. Philip otl died in 1322 around the time or just before the marriage was annulled I believe. If Philip was still alive around the time his father considered annulling the marriage, what happens to his status? is he still considered the legal heir to the throne, does Charles look to marry again?
