Source file ownership

Hello guys,

Its me again, i posted a thread about one of my client delaying the payment…

Yea he paid me, recently he contacted me again asking for the source files.

After he being a pain in the *** to me, I think i would like to return the favour.

We didnt have any agreement of the source files ownership, however does he have the rights to claim the source files?

I created the source files, I should have the ownership.

And can I sell him the source files instead?

Hehhehe

regards
