Rating: 10 Lawyer Rating - 10 out of 10
I could be redundant and repeat all that I have listed above but to be brief, I will summarize by saying that Mr. Castaner deserves a "10" because he is a genuinely nice person, who is very bright, energetic, diligent, honest, trustworthy, scholarly, well spoken, and in the midst of turmoil and adversity somehow manages to have fun in the process. If I needed a lawyer in Puerto Rico, I would not hesitate to hire Alberto Castaner.

A must lawyer in PR Astute, fast and diligent, Mr. Castaner is the partner you need to represent you in Puerto Rico. From your initial contact, he will guide you through all the necessary steps to secure the best outcome the law can deliver. A must in PR just when you need him the most.

I can not say how grateful I am, for this guy! I highly recommend attorney Castañer to anyone looking for a personal injury lawyer in Puerto Rico. I talked to four other attorneys before him, and they all told me I had no chance of recovering from the establishment where I suffered a serious accident. Not only did Castañer take my case, but he was able to settle it for a lot more than we had anticipated. He always kept me appraised of the status and progress of my case and was very kind and understanding.

Q. Which is the name of the law that determines the percentage of honorary (and the %)the lawyer receive in cases of injury
A: The law is Act No. 9 known as Practice of Law Act and provides:

No attorney shall charge fees of a contingent nature in actions to recover damages in an amount that exceeds, for any reason, twenty-five percent (25%) of the final proceeds of the judgment, compromise or agreement if the client is a minor or mentally disabled, or thirty-three percent (33%) of the final proceeds of the judgment, compromise or agreement if it is any other client.

Q. How can I file a small claims law suit in Puerto Rico? I
A: Good morning:

There is no "small claims" court for personal injury claims in Puerto Rico. You will have to file suit in state court or federal court (if your claim exceeds $75,000 and you and the defendant live in different states). If you plan to sue a cruise ship, be advised that most cruise ship lines have a forum selection clause which require that you file suit in Miami. If the excursion company is based in PR and you live in the mainland US, you are better off filing suit in federal court where you have a right to a trial by jury (provided that you meet the above conditions) which is not available in state courts.

Feel free to contact us should you have additional questions.

Q. Failure to pay for storage on a boat storage lot
A: Good afternoon:

You must look into Alaska state law for available remedies. If the contract was purely for land storage and no maritime services were rendered, maritime law would not apply and the land owner may not seize (or arrest) the vessel in federal court under admiralty procedures. However, a similar remedy may be available under Alaska law so we recommend you contact a local attorney for advise.

Hope this was helpful.

Best Regards,
