Custom Contracts in Barcelona: Drafting, Review, and Negotiation with Legal Certainty

We draft a customized contract tailored to your needs: civil, commercial, labor, or administrative

Why should you trust us to draft your contract in Barcelona?

A contract isn’t just “a piece of paper”—it’s your safety net if something goes wrong. At Martínez Caballero Abogados, we draft and review customized contracts (civil, commercial, employment, and digital) so you can sign them with clarity, balance, and legal backing. If you already have a draft, we’ll refine it and negotiate the key clauses.

Avoid problematic clauses and ambiguities

Contracts tailored to your specific situation—we don't use generic templates

Preventive Approach: Sign the right documents today = fewer lawsuits tomorrow

Why does a “customized” contract make a difference?

A valid contract requires certain essential elements (consent, subject matter, and consideration) and must comply with the legal limits on the agreed-upon terms.
In practice, problems arise when:

  • Templates are used without being adapted (they don’t truly fit the business)

  • Prices, deadlines, deliverables, and responsibilities are not clearly defined

  • General terms and conditions are included without meeting the requirements for incorporation

  • In the consumer/e-commerce sector, risks arise from unfair terms or a lack of information

For contracts with general terms and conditions, the law requires rules regarding incorporation and transparency.
And if you enter into contracts with consumers, there is a specific framework governing non-negotiated and unfair terms.

What We Do for You

Drafting Contracts from Scratch

We draft a comprehensive document tailored to your specific situation: roles, obligations, price, term, penalties, warranties, confidentiality, data protection, jurisdiction, and dispute resolution.

Review and Improvement of Existing Contracts

We identify risks, “fine print,” unfair terms, and unregulated issues. We propose clear, negotiable changes (in plain language).

Negotiating clauses with the other party

If you need help, we can assist you in negotiating the critical points: payments, exclusivity, non-compete clauses, intellectual property, penalties, termination, and limitation of liability.

Types of contracts we typically work on (the most in-demand)

Commercial Contracts (Companies / Self-Employed Individuals / Small and Medium-Sized Enterprises)

  • Service Provision / Consulting

  • Agency / Distribution / Partnership

  • Partnership Agreement / Agreements Among Partners

  • NDA (Confidentiality Agreement)

  • Sale and Purchase of a Business / Assets

Employment Contracts / Employment Relationships

  • Confidentiality and Non-Competition Clauses

  • Basic Internal Policies and Supporting Documents (as applicable)

Digital Contracts (Web / E-commerce / SaaS)

  • Online Terms and Conditions

  • Cancellation / Refund / Payment Policies

  • Legal Notice and Compliance with the LSSI for the Provision of Online Services

  • Data Processor Agreement (if there are vendors that process data)

How We Work (A Fast and Clear Process)

1) Briefing (15–20 min)

We ask you only the bare minimum: your goal, the parties involved, risks, payments, deadlines, and “what you don’t want to happen.”

2) Submission of the draft + explanation

We’re sending you a draft and a summary in “plain language”: what protects you, what you should watch out for, and where it’s best to negotiate.

3) Final version ready for signing

We incorporate the changes, add appendices (deliverables, SLAs, pricing, data protection), and prepare the contract for signing.

  • Civil contract: starting at €200

  • Employment contract: starting at €250
