Just checking - are you meaning that you need to hold shares 45 days before share is ex dividend to receive franking credits?
If that is your meaning i can assure you that the legislation says you need to hold shares "at risk" for 45 days (+ purchase and sale date ie. 47 days total). At risk means hedging of less than 70% . The 45/47 days can include days before and after dividend is declared. This is poorly understood by some brokers ( who say you must hold for 45 pre div) despite being specifically mentioned in the expanatory docs that accompany the legislation.
If this isnt what you meant then sorry for getting so technical.
