This question is very unclear. There are words here that are usually not found together - public defender and workman's comp case; sued for guardiaship; "winning" a guardianship case. Please re-post this question once you have ascertained the true nature of the proceedings and the people involved. If an attorney was involved - either the "public defender" or another - please see if he or she can help you understand the situation a little better.
Please note: The above is for general information purposes only. It is not intended to establish and does not establish any attorney-client relationship.
Usually payment for fees is governed by statute. To find an answer you might want to post in the subject area where the matter was held. For example, if this was a workers comp case, post in that area.
