No, they’re yours to keep.
There are various items you own which are exempt (protected) under bankruptcy law. Utah law provides various exemptions, most of which are found in Utah Code 78B-5-505. “Property exempt from execution.”
The specific code section here states that: “(1) (a) An individual is entitled to exemption of the following property: (i) a burial plot for the individual and the individual’s family….”
This means that your pre-paid burial plot is protected when you file bankruptcy. It doesn’t matter whether you file a chapter 7 or a chapter 13 bankruptcy. In a chapter 7 bankruptcy, the trustee cannot take that asset and sell it for your creditors. In a chapter 13 bankruptcy, the trustee cannot demand that you pay the value of that asset to your creditors.
It is safe.
