1. Coercive Control & Retaining Keys

🚪 Keeping keys to your property (car, house, post box) without your consent is a form of coercive control.

• It limits your freedom, independence, and ability to access your own belongings.
• It is often used to exert power and cause distress, especially in cases of domestic abuse.

📌 Legal Basis in Spain
Under Article 172 ter of the Spanish Penal Code, coercive control is considered a criminal offense, especially if it happens in the context of domestic violence.

• This includes controlling access to financial resources, personal property, communication, and daily life.
• If withholding keys causes you psychological harm or restricts your autonomy, it strengthens your case.

✅ Steps to Take:

• Request the keys in writing (text, email, WhatsApp) for proof.
• If refused, report it to the police (Guardia Civil or Policía Nacional).
• Inform your lawyer to use it as evidence in court.

2. Withholding or Stealing Mail = Coercive Control & Mail Theft

📬 Taking, hiding, or withholding mail (especially recorded delivery post) is illegal and another form of control.

• Article 197 of the Penal Code protects private correspondence and penalizes mail theft.
• If someone takes your mail, especially financial documents or legal letters, it can be reported as theft.

✅ Steps to Take:

• Report missing mail to Correos (Spanish Postal Service).
• Request a record of any signed-for deliveries (proof of fraud if someone else signed).
• File a denuncia (police report) for stolen post.
• Give all evidence to your lawyer and court-appointed psychologist.

3. How This Helps Your Case

📝 Evidence of coercive control can:

• Strengthen your legal case for domestic abuse or financial control.
