This range reflects both the complexity of a standard petition under Missouri law and local attorney hourly rates in the Hillsboro area, which typically run $250–$400/hour.

Guardian Ad Litem in Jefferson County, Missouri
Attorney for respondent appointed (RSMo § 475.075). In Jefferson County, the Jefferson County Circuit Court, Probate Division routinely appoints an independent advocate — variously called a guardian ad litem, court visitor, court evaluator, or attorney ad litem depending on the state's statutory terminology — to independently investigate whether guardianship is necessary and appropriate.

The GAL or court visitor's fees are considered a cost of the guardianship proceeding and are typically paid from the ward's estate. In most Missouri jurisdictions, including Jefferson County, the court sets the GAL's fee at a reasonable hourly rate. For simple, uncontested cases in Jefferson County, the GAL's total fees often range from $500 to $1,500. In contested proceedings, the investigation may be more extensive and the fees correspondingly higher.
The GAL's recommendation carries significant weight with the Jefferson County Circuit Court, Probate Division, but it is not binding.
