If your ex-boyfriend refuses to return your house key and you have made reasonable attempts to contact him without success, it might be appropriate to consider involving the police. However, before taking any legal action, you should consider the following steps:
Document your attempts to contact him: Make a record of all your attempts to communicate with your ex-boyfriend regarding the key. Note down the dates, times, and methods of communication (texts, calls, emails, etc.).
Keep a record of any responses or lack thereof: If your ex-boyfriend responds, document the content of his response. If he does not respond at all, keep track of the lack of communication as well.
Check local laws: Laws regarding property and key possession may vary depending on your jurisdiction. Research local laws or consult with a legal professional to understand your rights in this situation.
Seek legal advice: If you believe your ex-boyfriend is unlawfully withholding your property (the house key), you may want to consult with a lawyer to understand your options and the appropriate course of action.
Involve the police (if necessary): If you have attempted to resolve the issue amicably and your ex-boyfriend still refuses to return the key, you may consider filing a police report. The police can help mediate the situation and, if necessary, advise you on how to proceed legally.
When involving the police, it is crucial to remain calm, provide them with all the relevant information and documentation, and let them handle the situation appropriately.
Remember, the above advice is not legal counsel. To ensure you take the right steps for your specific situation, consult with a legal professional who can provide guidance based on the laws in your area. They can help you understand your rights and the best way to resolve the issue.
