No, not necessarily. The fact that an estate has more debts than assets does not automatically mean that you have to renounce it.
In principle, heirs are not liable for the deceased's debts beyond the value of the assets they inherit. However, this protection is subject to the rules governing the settlement of the estate, and certain exceptions may apply.
When an estate appears to be insolvent, you should avoid making decisions solely based on the apparent amount of its debts. It may be necessary to verify, in particular:
If the estate's assets are insufficient to pay all debts and specific bequests, the Civil Code of Québec provides for a specific procedure that the liquidator must follow. Creditors are then paid according to the rules and order prescribed by law.
Renouncing an inheritance remains an option for a potential heir who does not wish to become one. However, it must be done in accordance with the applicable rules and within the prescribed time limit.
Before renouncing an inheritance that appears to be in deficit, it is therefore generally preferable to obtain sufficient information about one's financial situation and to check the consequences of each of the possible options.
