Do I need the source code or access from my previous agency?

Ideally yes. For a clean takeover, we need access to the server (SSH), the database, the hosting panel and the CMS backend. If your previous agency developed custom plugins or individual modifications, access to the source code of these extensions is additionally very helpful, since otherwise we first have to reconstruct how they work.

In reality, handovers are rarely complete, especially when the separation from the previous provider was not smooth. Should individual access be missing, we can find alternative paths in most cases, for example via the hosting provider or by analyzing the running system. Which documents are really necessary for your case and how we bridge gaps is something we clarify concretely in the initial consultation.
