Confidential consultation
Share the objective and the facts you already know.
We will assess the lawful options and identify the smallest reasonable next step.
Confidential contact
Start with the objective and the facts you already know.
Telephone and email contact let us assess whether an assignment has a lawful and proportionate next step.
Before the first call
A clear objective is enough to begin.
You do not need a complete case file or to obtain additional information on your own. A short chronology and lawfully held material are helpful.
- Objective. One question the assignment should answer.
- Timeline. Key events, known dates and locations.
- Lawfully held material. Documents, messages or images without accessing another person’s accounts or devices.
- Relevant identifiers. A vehicle description, photograph or company information, only when relevant.
- Time constraint. A hearing, meeting or known date that makes the finding important now.
