Evidence

Yes Call records and whatsapp chat records can be produced in family court to prove the point in question. You may be required to prove that their is no fabrication.

ok thank u sir...how can v prove that there is no fabrication ?

i think call record time and time of call duration according to telecom operator can help to prove ??

yes you can prove through call records and whats app chat. but said evidence is required to be proved as per section 65 A & 65B  of Indian Evidence Act. to prove as per above provision, you will require help of good advocate who is good in exhibiting the documents.
