Are there Court Costs for all involved in the same estate planning case?

The court costs are separate from attorney’s fees. Whomever opened the estate (usually the person wanting to be the personal representative) was the person who paid the filing fee to the clerk of court. However, if the estate planning case is contested and each person has their own attorney, each person will be responsible for paying their own attorney’s fees. Discuss with your attorney about whether you can recover those fees (and any additional costs that you may have such as deposition costs, postage, copies, etc.) from the estate.
