Legal analysis: no, parents' guarantee for others will not affect their children, and children do not need to bear the responsibility of parental guarantee. The guarantor assumes the guarantee responsibility because of the existence of the guarantee contract, and because of the principle of relativity of the contract, the guarantee responsibility only exists between the parties to the guarantee contract and does not bear the responsibility to the third party.

Legal basis: Article 388 of the Civil Code of People's Republic of China (PRC) establishes a security interest, and a security contract shall be concluded in accordance with this law and other laws. Guarantee contracts include mortgage contracts, pledge contracts and other contracts with guarantee functions.

The guarantee contract is a subsidiary contract of the main creditor's rights and debts contract. If the principal creditor's rights and debts contract is invalid, the guarantee contract is invalid, unless otherwise stipulated by law.

If the debtor, guarantor and creditor are at fault after the guaranty contract is confirmed to be invalid, they shall bear corresponding civil liabilities according to their faults.
