What you need to know
Ownership covers separate assets: domain, hosting, source code, design files, text, photos, analytics, and third-party accounts. The agreement should say who controls each item and what is handed over.
How to apply it
Register the domain with a business-controlled account, keep admin access, list licensed assets and paid tools, and ask which files and credentials are included in handover.
Common mistake to avoid
Paying for development does not automatically give access to every account or licensed component. Confirm the terms in writing.
