Yes, provided they were obtained lawfully. WhatsApp exchanges you were a party to, screenshots and exported records can all be put before a court, and their integrity can be reinforced by having them formally determined before a notary or examined by an expert.
What decides it is how the evidence was obtained. The Code of Civil Procedure (No. 6100) provides that evidence obtained unlawfully cannot form the basis of a judgment. So getting into the other side’s phone without permission, breaking a password or covertly acquiring third parties’ private messages does more than invalidate the evidence: it can amount to the offences of violating the confidentiality of communications and of unlawfully obtaining data under the Turkish Penal Code (No. 5237). The safe route is to have the conversation you are genuinely a party to determined by the proper method, and we help you assemble it so that it holds.
