VAWA and FVPSA require releases to be "reasonably time-limited." Whether a time limit is reasonable should be determined by the purpose of the release and the circumstances of the survivor's situation. The length of time that a release is effective should be the minimum length of time necessary under the circumstances, and should be tied to the service the survivor is requesting. It should be as short as necessary to meet the client's purpose (for example, a release could be for a few minutes, or a few hours, or a few days). This helps to ensure that services are guided by the survivor and take into account situations that may change radically from day to day.
In general, there is no reason a waiver should ever be more than 15 days or 30 days since the release can be reaffirmed and extended if the survivor confirms that the release is still valid and authorizes a new expiration date.
