If the Conservators works out, Thomas Jr will oversee all of his father’s financial affairs and make decisions on his behalf.
It will also mean Thomas Jr will oversee the court case between his father and British photographer, Jeff Rayner.
Mr. Markle was caught on CCTV posing for faked photographs taken by Mr. Rayner, which were then sold for a reported £100,000 to media outlets.
The photos show him being measured for a suit to wear to the wedding, browsing a book of British landmarks, and working out with weights to get in shape ahead of the big day.
Information about the conservatorship arrangement was revealed in court documents filed in the Rayner case.
Meghan’s half-brother told the court he was “in the process” of obtaining the conservatorship for his father.
A well-placed source told the Sunday Mirror: “Tom Snr has had a series of health scares and his son wants to do the best for him by taking any stress away. Cases in America grind on for months or years so it will be a weight off Tom Snr’s mind. It will help him focus on his recovery.”
