Within how many days should a dependency petition be filed after a shelter hearing?

A dependency petition should be filed within 21 days after a shelter hearing. This answer may seem obvious since it is the correct option, but it's important to explain why the other options are incorrect. Option B of 7 days is too short of a time frame as it may not allow enough time for the necessary paperwork to be completed and filed. Option C of 28 days is too long as it may delay the process and put the child's safety at risk. Option D of 15 days is also too short and may not allow enough time for all necessary parties to be notified and for the court to make a decision. Thus, the correct answer is A, 21 days, which allows sufficient time for all necessary steps to be taken.
