If you are concerned that you may inherit debts from someone who has died, or if you simply do not want to inherit anything from someone, you can renounce an inheritance.
Good to know
If, prior to the distribution of the estate, an heir appropriates items that form part of the estate (other than items of no value) or does something that is not simply part of the administration of the items making up the estate, that heir loses the right to renounce their inheritance.
