Frequently asked questions

A template isn't binding on its own - like any contract, it becomes binding once it's properly completed and signed. Templates in our curated library are professionally drafted for US or UK law; review any template before you sign it.

Describe what you need in the chat and GitLaw will draft it for you.

Templates in our curated library are professionally drafted for US or UK law. The wider library comes from the GitLaw community and public sources - a solid starting point, but check any template fits your situation before you rely on it.

Mostly US and UK law. Some templates use general commercial terms that work across jurisdictions, and many note which law they're written for.

It depends on the situation. Templates work well for routine business agreements. For anything involving significant money, complex IP, employment, or areas you're unsure about, it's worth getting professional advice before you sign. GitLaw provides templates and tools, not legal advice.

Open any template in GitLaw and describe the change you want in the chat — 'make clause 4 mutual' or 'add a 30-day notice period', for example. GitLaw drafts the revised language and shows it as a suggested edit. You accept, reject, or keep editing from there.

Yes. Upload a Word, PDF, or Markdown file and GitLaw will open it in the editor. You can review, edit, or chat with GitLaw about it the same way you would with any template from the library.
