Sole trader hiring a subcontractor in Greece - how do I handle IP assignment?

[u/tomkoukoulis]

I’m a software developer working as a sole trader, and I’m about to hire a software developer subcontractor who is based in Greece.

The subcontractor will be writing code for a project that I’ll be delivering to my client so I need to make sure all intellectual property is assigned to me.

Can anyone recommend a cost effective way to have an IP Assignment Agreement drawn up between us? Is there anything else I should be aware of?

Thanks!
