An initial fee waiver shall be granted by the court at any stage of the proceedings at both the appellate and trial court levels if an applicant meets the standards of eligibility and application requirements under Sections and 68633. An initial fee waiver excuses the applicant from paying fees for the first pleading or other paper, and other court fees and costs, including assessments for court investigations under

Section 1513, 1826, or of the Probate Code, as specified in rules adopted by the Judicial Council, unless the court orders the applicant to make partial payments under subdivision (

c) of

Section 68632, subdivision (

d) of

Section 68636, or subdivision (

e) of

Section 68637. Under circumstances set forth in

Section 68636, the court may reconsider the initial fee waiver and order the fee waiver withdrawn for future fees and costs or deny the fee waiver retroactively. At the end of the case, the court may recover fees and costs that were initially waived under circumstances set forth in

Section 68637. Upon establishment of a conservatorship or guardianship, the court may collect all or part of any fees waived pursuant to this

section and

Section from the estate of the conservatee or ward, if the court finds that the estate has the ability to pay the fees, or a portion thereof, immediately, over a period of time, or under some other equitable agreement, without using moneys that normally would pay for the common necessaries of life for the applicant and the applicant’s family.
