If the 125 case cross has been done earlier and its favourable to you then using section 145 of indian Evidence Act which states "
Cross-examination as to previous statements in writing.
1*145. Cross-examination as to previous statements in writing.-A
witness may be cross-examined as to previous statements made by him in
writing or reduced into writing, and relevant to matters in question,
without such writing being shown to him, or being proved; but, if it
is intended to contradict him by the writing, his attention must,
before the writing can be proved, be called to those parts of it which
are to be used for the purpose of contradicting him."
You can use the previous statements of 125 case and cross examine your wife. Do ask a question if she denies that 125 statements are not true...then ask DV judge to note that and tell you need these statements to file complaint against your wife in 125 case for giving false evidence....she and her advocate may dance there itself....ONLY catch Judge SAHAB should listen to you.
