[Louisiana] I purchased a property from my brother who was a minor – was the money supposed to be set aside in a bank account?

Location: Louisiana

My dad died when I was younger. At the time, my brother was 10 years old and inherited a piece of land my dad owned. I inherited other stuff.

I then legally purchased the land from my minor brother through an attorney. Our uncle was his legal guardian at the time and signed everything on my minor brothers behalf.

Well fast forward to today, my brother is now an adult. When he asked my uncle about his money from the sale of the land my uncle admitted they spent it all.

It was from my understanding that when I purchased the land, my uncle was supposed to put the money into an account for savings. Was he legally allowed to spend it how he saw fit??? Is my brother screwed?

The property was purchased for $15,000
