When a conservator appointed by the court becomes insane or otherwise incapable of discharging his trust, or unsuitable therefor, or has wasted or mismanaged the estate, or failed for thirty (30) days to render an account or report, the court may upon such notice to the conservator as the court may require, remove him and compel him to surrender the estate to the person found to be lawfully entitled thereto.
