This summary is not the rule. The rule text controls.
If someone is handling an estate (a succession representative) and there's property that could spoil or lose value quickly, like farm crops or other perishable items, they can ask the court for permission to sell it right away. This rule lets the court approve a fast sale so the property doesn't go to waste or lose its value while the estate is being settled.
The court has flexibility in how this sale happens. It can allow the property to be sold at a public auction or through a private sale, whichever makes more sense for the situation. The court can also skip the usual steps that normally slow things down, like getting an official appraisal first or advertising the sale to the public. If the court decides some advertising is still a good idea, it can require that instead, but it's not required by default.
This rule exists because some property just can't wait for the normal, slower process of settling an estate. Crops in a field or other perishable goods lose value fast, so the law gives the court a way to act quickly and protect the value of the estate for everyone involved.
