While Filip Telibasa, owner of Benzina Wealth in Sarasota, Florida, hasn't had any lottery-winning clients he did have one who inherited close to $10 million from a wealthy uncle.

"No, that's not a Netflix plotline," he said. "It was real life, and he had a pretty average life beforehand. Worked for the [Metropolitan Transportation Authority] in New York, making an average salary. Once he discovered the inheritance, his emotions went from excitement to panic quickly. He didn't want to make any mistakes."

That's why Telibasa said his advice to a Powerball winner would be to stay anonymous, breathe and hire a team, including an attorney, a financial planner and an accountant, before claiming a single dollar.

"They do not need to have prior experience with major windfalls, though this may be a plus," he said. "The attorney sets up trusts or LLCs to protect privacy and reduce liability. A financial planner creates the road map so you can enjoy some of the money today without sabotaging your future. And an accountant keeps the IRS from becoming your biggest beneficiary."
