Trust Administration: Co-Trustee Claims Last Minute Trustee Fees Upon Final Distribution

My question involves estate proceedings in the state of: Florida

In an article, "What Is a Reasonable Trustee’s Fee?" it was concluded that, "Therefore, any compensation to be paid to a trustee must be contained within trust accountings, unless waived by all interested parties. "

Question:
Does this also pertain to trustee fees as well? That trustee fees to be paid (to the co-trustee) must be contained within trust accountings, unless waived by all interested parties. "

The co-trustee for my father's estate decided at the last minute to deduct $100,000 from the final distribution to the beneficaries, for her trustee fee. Is this allowed? Are there any cases that you can refer me to?

Is there any cases that you can refer me to, that point this out?

Thanks Mark
