Your lawyer receives everything through a secure link, even if they do not use Prismo.
See how it worksA separation is not something you win. It is something you prepare for.
When the facts are unclear, conflicts get worse. When they are clear, everyone can move forward, starting with the children. Prismo brings that clarity, then leaves the defense to the lawyer and the decision to the judge.

Guidance at every step
When you sign up, a few questions (children, housing, income, assets) are enough to work out which documents to gather. Prismo gives you a checklist and tells you what is missing. The “Understanding” guides explain the rules of evidence without jargon.
For law firms: guided onboarding and invitations ready to send.
