Our Missing Plaintiff Service

.Is your plaintiff or class action representative missing or non-responsive? We specialize in getting missing or reluctant class action reps and plaintiffs back on board with your case as quickly as possible.

What we do, typically within a 24-48 hour time period:

1) Conduct a thorough locate investigation to identify any new addresses, phone numbers, work information, or other contact methods, such as social media

2) Identify spouses, parents, relatives, roommates, etc, who may be in contact with the subject

3) Reach out directly to the plaintiff with the new contact data and ask them to contact your office.

4) Contact relatives, roommates, etc, and encourage them to ask the plaintiff to contact your office.

5) We go in person (anywhere in California) and conduct a door knock to contact the plaintiff personally and encourage their cooperation.

6) If they are not there, we gather intel as to when we can contact the plaintiff and we encourage whoever is home to help get the subject to contact your office,

7) If we find the plaintiff and they are convinced to cooperate, we can have them sign declarations or settlement documents.

8) If we contact the plaintiff and they are still uncooperative, we can hand deliver a letter from your office informing them of the possible negative consequences of their failure to cooperate.
