Previous Claims in Third-Party Proceedings


In the special case of a claim prior to the civil proceeding, by virtue of which a third party seeks to intervene in the enforced collection procedure filed by the Treasury General of the Social Security against an individual with debts owed to Social Security by claiming certain rights in relation to said debtor.


There are two categories of third party proceedings:

  • Third party claim to ownership, based on ownership of the debtor's seized property, whereby a third party claims the right to ownership of said property, by claiming and providing evidence of said ownership.
  • Paramount right of a third party, based on the third party's right to have their credit reimbursed, taking priority over the debtor in the enforcement procedure filed by the Treasury General of the Social Security. This type of third party proceeding does not aim to demonstrate ownership of the asset but rather to demonstrate that the third party claimant takes precedence or has the paramount right to be reimbursed the sum of money being pursued through the enforced collection procedure.

Minimum content:

The third party claim must be formulated in writing accompanied by the original documents that form the basis of the third party's claim along with copies of said documents, if the third party wishes the original documents to be returned to them once they have been checked.
