Is it permissible to swear falsely before a judge to ward off injustice, and are there examples of equivocation (tawriya) in this situation?

If the questioner knows that the properties do not belong to his relative but to his partner, and before they are registered in his relative’s name, then this is an aid in squandering the partner’s right and consuming his wealth unjustly. The way out is to state the truth to the judge and testify that the property belongs to his partner, so that the judge may investigate and restore the right to its owner, and the questioner’s conscience may be cleared.
