Marital investigations are typically conducted by private investigators to gather evidence related to divorce proceedings, such as infidelity, child custody, or concealed assets in the division of marital property. Law firms then use this gathered evidence to file more favorable arguments in family court or the High Court. The legal process usually involves filing a complaint, exchanging documents, and sometimes requires hearings or special mechanisms, such as child settlement mediation (CDR).
■ Difference Between Private Investigations and Court-Ordered Investigations
• Private Investigations: These investigations, not ordered by the court, are conducted by private investigators. They primarily gather evidence before divorce proceedings begin to achieve the following objectives:
Proving infidelity: Gathering evidence through photographs, videos, and digital data.
Child custody investigations: Monitoring parental lifestyles to identify any neglect in childcare and ensure children's safe upbringing.
Tracing hidden assets: Revealing undeclared income and property to ensure a fair distribution of marital assets.
Background checks: Verifying the financial records or past professional history of potential partners.
• Court-Ordered Investigations: Under Section 29AB of the Matrimonial Procedure and Property Ordinance (Chapter 192), the court may proactively order the initiation of investigations, including voluntary disclosure by both parties and verification through questionnaires, particularly concerning ancillary support matters such as alimony determination or asset division.
■ How can the collected investigative evidence assist in litigation?
Strengthening Litigation Stance: Evidence gathered by private investigators can assist legal teams in developing more comprehensive litigation strategies for their clients.
Providing Evidence of Infidelity Allegations: Photographs, videos, and other documentary evidence can support a client's claims regarding infidelity or misconduct.
Protecting Legal Rights: Concrete evidence safeguards legal rights in divorce proceedings.
■ How to Apply Collected Investigative Evidence in Legal Proceedings?
• Filing a Complaint: The first step in initiating legal proceedings. Providing evidence of infidelity can shorten the required pre-divorce separation period.
• Claiming Dependent Relief: Uncovering hidden assets can ensure a legitimate claim for alimony, property transfer, or asset division.
• Child Dispute Resolution (CDR): Evidence of neglect in childcare by the other party or an undesirable background regarding the other party's future partner can effectively secure sole custody of the children.
