The former couple reportedly signed the deal, which is estimated to be worth between $15 and $20 million, at the end of last year, with official paperwork expected to be filed in court within the next coming days.
The settlement came just as their marriage was reaching its 10-year mark. Their prenuptial agreement says Weinstein must pay Chapman $300,000 in spousal support for each year of marriage — and after a decade that figure jumps to $400,000.
As previously reported, Chapman could get as much as $12 million now that their 10-year anniversary has passed.
Chapman, a fashion designer, will also get a slice of their marital assets and other payments, sources said. Their holdings include a $15 million West Village townhouse and a $12 million Hamptons beach house.
Sources also said that the settlement process was so painstaking that it almost collapsed, which would have forced the parties to bring a public divorce case.
Chapman, 41, announced she was leaving 65-year-old Weinstein in October after a New York Times exposé accused the power producer of dozens of accounts of sexual misconduct, ranging from harassment to assault.
Weinstein and Chapman have two children, ages 7 and 4; Chapman will reportedly get primary custody.
