An interim grant is usually approved by the Court if there is some sort of contention during the probate process, allowing an independent third party to continue working on the administration until the problem reaches a conclusion.
The interim grant is only permitted to be in force during the period of the Court case and tends to be given to an accountant or solicitor. During this time, the individual administering the Estate cannot begin to distribute any assets. Their job is solely to protect the assets contained within the Estate.
So, regardless of whether or not a Caveat has been registered with the Probate Registry in an attempt to halt the process, the deceased’s Estate will continue to be administered with outstanding bills being paid and daily tasks being carried out as normal, until the probate dispute has been resolved.
