My wife and inlaws have filed DV and dowry (498a DP3/4 etc). Before we started to live separately, she forgot her educational documents at my place, which is abroad. Afterwards she started to give me threats for her documents and wanted me to bring (or send) her documents to her doorstep. I have already send her docs to India and I want to give back her docs but don't want to get in any other trouble. I don't want to give those backswithout getting a written proof that she has recieved everything intact.
Last time I contacted Father in law (before I got to know 498a &DP3/4) he was adamant that the docs should reach to his home first and only after that he will discuss anything.
Please suggest how to properly return her educational documents and save myself from any hassle for those. Can I send her notice (legal) for not contacting for her doucments?
