b. In the case of the third party’s custody or co-custody
1 The creditor and debtor may bring an action against the third party to have his claim declared unfounded if the claim relates to
1.
a movable item in the custody or joint custody of the third party;
2.
a claim or other right, provided that the third party’s entitlement is more likely than that of the debtor;
3
immovable property, provided the claim is recorded in the land register.
2 The debt enforcement office shall set them a deadline of 20 days to do so.
3 If no action is filed, the claim shall be deemed to have been recognised in the debt enforcement proceedings in question.
4 On the demand of the creditor or the debtor, the third party shall be requested to submit his evidence to the debt enforcement office for inspection within the time limit for bringing an action. Article 73 paragraph 2 applies mutatis mutandis.
