Questions
Do I need a written contract as a freelancer in Spain?
A written agreement is widely used because it records scope, price, deadlines and who owns the work. Whether specific clauses are required depends on the law in Spain and on your client, so check the rules that apply to you.
Are the FormSphere templates legal advice?
No. They are general-purpose, country-neutral templates. You choose the governing law, currency and tax wording. For anything important, ask a qualified adviser in your country.
Does FormSphere sell official government forms?
No. For official registration and tax forms in Spain this guide links to the authority's own site, where the current version is published.
Can I fill the documents in without printing?
Yes. The Freelancer Kit documents are fillable AcroForm PDFs that work in a normal PDF reader.
