Parents' debts have nothing to do with their children, and they cannot ask for debts from their son's unit on this ground.
 In our country, there is no law to say that the father owes the son.
 Adult children are legally separate from their parents, and their own debts are borne by themselves. Only under certain circumstances, the debts owed by their parents need to be repaid by their children.
 When parents are in debt and die unexpectedly, if parents still have creditor's rights or property, these creditor's rights or property should be used to repay others' debts first. After the debts are paid off, they can inherit the remaining inheritance as heirs.
 If children do not inherit their parents' inheritance, they do not have to repay their parents' debts. If they voluntarily repay their debts, they are not within this limit.
 [Legal Basis]
 In Article 1161 of the Civil Code, the successor shall pay off the taxes and debts payable by the decedent according to law to the extent of the actual value of the acquired estate. This restriction does not apply to the part exceeding the actual value of the estate that the heir voluntarily repays.
 If a successor waives inheritance, he may not be responsible for paying the taxes and debts that the decedent should pay according to law.
