During the period when the qui tam complaint remains under seal, you will remain anonymous to the public and the defendant, but your identity will be known to the government. Once the seal is lifted, the qui tam complaint becomes a public document and your identity will be revealed.   There are circumstances in which you may be able to voluntarily dismiss a qui tam complaint during the seal period without the defendant learning your identity, but there is no guarantee of anonymity.  There are also strategies that your attorney can utilize to reduce the possibility that your identity will be disclosed. However, it is a rare exception when a relator is able to remain anonymous indefinitely, and you should expect that your identity will eventually be revealed if you file a qui tam complaint.
