The stuff about a "form" doesn't make sense. Perhaps the lawyer was looking for a motion to probate a copy of a will he could use as a basis for drafting a motion in your current case, although it seems your current lawyer could do that. When a will is lost there is a presumption that the decedent destroyed it intentionally, and that must be overcome in order to probate from a copy. Talk to your lawyer about what, exactly, your first lawyer meant by a "form" and whether it will be possible to proceed through probate based upon the copy of the will.

The estate has assets (the bank accounts) and expenses (property taxes, etc.) that it should be paying. It may well be that the estate also owes taxes. Who is the personal representative, and why aren't they attending to the estate's bills and to funeral expenses?
