it is indeed an affidavit.

It may only be needed to move forward with the claim, but I always suggest to not sign an affidavit.

Ultimately, It's your call.

My question was, what do I have to do in this situation (which regularly happen) : The delivery guy comes to my house and call me to take the package from him, but my question is, how do I manage this situation ? I have to answer the call because otherwise he leaves with the package, but if I answer the call, there will be a proof that I was here to receive the package.

Just because you answered the call, It doesn't necessarily mean he successfully handed over the package to you, personally.

He could've left with the package In hand. A phone call doesn't confirm receipt of goods.
