Wills, probate, letters of administration, powers of attorney
The normal chain of events is that the person who applies for administration of an intestate estate would pay for things that fall due during the process, in anticipation of receiving administration of the estate. Accurate records should be kept so that these amounts could be reimbursed once administration is granted.
The estate is subject to the normal rules of probate so the court would need to be satisfied that all monies are properly accounted for.
Beneficiaries would receive the percentage of the estate as determined by the laws of intestacy together with a copy of the records as provided to the court. The administrator needs to properly account for his expenses and these need to be outlined in the accounts of the estate. The administrator cannot charge for his time in doing this unless that administrator is a professional (eg accountant) engaged to do this work.
