Trust, trustees and personal representatives

What is the name of your state? Maryland

My father just died. His will set up a revocable trust. The personal representatives are his attorneys and me (daughter). The trustees are me, my son and a bank. The attorney says I should "loan" the estate $5,000 so it can pay all the bills. Since I am both a personal rep. and a trustee, why do I have to do this? Can't I pay the bills?

Are you the trustee and your son and bank successor trustees? Are the personal representatives Co-personal representatives? Or, are one of you successor personal representatives? Who is the beneficiary of the estate? Just you? Are there liquid assets in the estate? Were there any retirement plans or life insurance involved? I would be willing to bet that the attorney and bank will make a chunk on this setup. How complex is the estate?
