An e-petition will remain open for signatures for 30, 60, 90, or 120 days, as determined by the e-petitioner when the petition was created. To receive final certification, an e-petition must receive a minimum of 500 valid signatures during this period. If an e-petition has not garnered the minimum number of signatures by then, it will proceed no further, but will remain visible online.
