Technical foundation in a dispute

In any litigation, the party presenting documented technical arguments has a solid foundation. A party-appointed expert report is a report commissioned by you to investigate the technical reality of the facts and support your position with objectivity and rigour.

When is it necessary

Before filing a claim — to assess the technical strength of the case. During negotiation — a well-founded report facilitates out-of-court settlement. As evidence under the LEC. To refute the opposing party's report through a counter-report.
