If you want to sell a minor's property through a private sale, you have to file a petition with the court that includes specific information. This petition must meet the general requirements already spelled out in Article 4271, but it also needs some extra details specific to private sales.
Your petition needs to describe the property clearly so the court knows exactly what's being sold. You also need to spell out the price you're asking and any conditions attached to the sale, like payment terms or deadlines.
Finally, you have to explain why a private sale is the better choice for the minor compared to other options, like a public auction. The court wants to see that selling this way actually benefits the child, not just that it's convenient for whoever is handling the sale. This helps the judge decide whether to approve the sale and protect the minor's interests.
