We delivered an AI Closing Coordinator for a three-attorney Mount Pleasant real estate closing firm -- one that opens every file the minute a contract lands and orders every document on its own, chases what is late against each closing date every morning, reorders payoff letters before they expire, and quarantines any email asking to change a wire before anyone on staff can answer it.

She passed the bar in 2004 and did her first closing at a card table in a model home in Park West. Her firm, in an office off Coleman Boulevard, is three attorneys and eleven staff now, and last year it closed 1,140 residential sales and refinances -- about ninety-five a month, in a state where an attorney has to be at every one of them. The closing itself takes forty minutes. What takes the month is everything that has to arrive first.

A title search. A payoff letter from every lender with a lien, each with a good-through date. An HOA estoppel letter from whichever management company runs the neighborhood. The CL-100 wood infestation report, a survey if the lender wants one, the insurance binder, and the lender's sign-off on the closing disclosure.

Each of those comes from someone outside the building who has no reason to hurry. Four paralegals chased all of it by email and phone, file by file, and the chasing ran behind the calendar. One closing in nine slipped at least a day, almost always for a document that had been ordered on time and then never followed up. Charleston AI put Claude Cowork to work under the firm's own account and gave it the files -- the intake inbox, the closing calendar, the title software and every outside party's address.

A signed contract landing in the intake inbox opens a file within minutes. The title search is ordered, the payoff requests go out to every lender on the seller's side, the estoppel is requested from the right management company and the buyer's agent is asked for the CL-100 -- before a paralegal has read the contract. At six every morning every open file is measured against its closing date. Anything missing at ten days is chased again, with the file number and the date.

Anything missing at five goes to the paralegal who owns the file, with what was sent and when. When a payoff letter arrives, its good-through date is checked against the day the money will actually move; if the letter expires first, a fresh one is ordered the same hour. The line it does not cross is money and judgment. It never sends, releases or changes a wire.

Any message that mentions new wire instructions is quarantined, never answered, and sent straight to the closing attorney with the phone number already on file for that party -- not the one in the message. It does not clear title exceptions, interpret a survey or tell anyone what a document means. Those belong to a lawyer. Everything that is simply getting the paper in, it owns.

The weekend that settled it was in May. The managing partner was at her daughter's volleyball tournament in Columbia, with a Monday 10:00 closing on Daniel Island on her calendar. Friday afternoon the estoppel came back showing $1,340 in unpaid dues. The ledger went to the seller's agent within the hour, and the amount went onto the draft settlement statement for the attorney to review.

Saturday the seller's first payoff letter hit its good-through date; a new one had been ordered Thursday and arrived Monday at 8:05. And at 11:48 Friday night an email came in that looked like it was from the seller's agent, asking that the proceeds go to a new account. The domain was one letter off. It was quarantined in under a minute.

Nobody answered it, and nobody on staff saw it over the weekend. She opened her laptop Monday at 7:30 to a single page. Everything that had been done, and one thing that needed her: the fraudulent email, the real agent's number, and a note that no reply had gone out. She called, confirmed the original instructions and closed at 10:00.

Five months in, slipped closings are down from one in nine to one in sixty. The four paralegals spend their day on the part of the job that needs a person -- the calls with nervous first-time buyers and the files with a real problem in them. Three more wire-change emails have come in since May. All three were quarantined before anyone opened them.

"I used to spend Sunday night scrolling through every Monday file," she said. "I don't anymore. What I get now is short, and when something's on it, it matters."
